    HEMP
    Biofuels, such as biodiesel and alcohol fuel, can be made from the oils in hemp seeds and stalks, and the fermentation of the plant as a whole, respectively. Biodiesel produced from hemp is sometimes known as "hempoline".[52]
    Filtered hemp oil can be used directly to power diesel engines. In 1892, Rudolf Diesel invented the diesel engine, which he intended to fuel "by a variety of fuels, especially vegetable and seed oils, which earlier were used for oil lamps, i.e. the Argand lamp."[53][54][55]
    Production of vehicle fuel from hemp is very small. Commercial biodiesel and biogas is typically produced from cereals, coconuts, palmseeds and cheaper raw materials like garbage, wastewater, dead plant and animal material, animal feces and kitchen waste.[56]

  • 1 simple question, is it efficient to just buy a panel say 120w and plug it in the home circuit?
    and what device is needed to do so?
    intention: instead of doing big business like selling produced electricity back (and all the technical equipment needed) a cheaper way to add some electricity at daytime, no batteries, just added selfproduced electricity
    (to be honest… to power 24/7 servers)

    • BreadAndButter BreadAndButter

      Hi catweazel, 120w? That won't get you far, I'm afraid (it's like 2 lightbulbs!) Usually, you measure solar panels in kWp (kiloWattt peak). A panel surface of 9-10 square metres will get you ca. 1000 kWh electricity per year, I think.

      catweazel, the short answer is "no" – it is not efficient to just buy a solar panel… especially if you want to power servers 24/7 without batteries.

      The bitcoin mining community is interested in such things because they tend to run 'puters 24/7, and there has been some interesting chatter about feasibility issues on their forums. For example:

      The easiest and fastest way to do zero carbon lifestyle is to switch to a 100% wind or solar or water power energy provider if you live in a deregulated energy state.

      Then buy an all electric car, plug it into this energy source. This works really well if your home is all electric.

      Voila… you are done.

      100% zero carbon, for home, car and potentially business too.

    The most available alternative fuel is being completely ignored and disposed of in the nations rivers. For those of you who are not aware, sewage can be used to grow multiple types of algae, natural gas, methane. The algae can be used to make oil or different species can be used to make a coal substitute. Not only is this algae available now the oil and coal substitutes can be used in jet aircraft,school buses, trains, ships, electric generators, trucks, and some cars now without modifying their engines or the distribution chains. Just our largest US cities produce enough sewage to not only supply enough fuel to replace our need to drill for oil or import it, we also have enough sewage to replace nuclear and coal mining while restarting the US and global economy. Sure, sewage may not be as glamorous to some as nuclear but sewage to fuel not only takes toxic nuclear by-products out of the equation it also has many other benefits such as reduction of eutrophication zones in the gulf of Mexico.

    As long as we eat we are going to make sewage. The sun is the source of all of our food. The most efficient use of the sun is to let none of its energy just get flushed down the drain while nuclear, drilling, and mining just keep on polluting.

    The best way to hurry up and get nuclear online is to promote a more beneficial energy source that is cheaper and reduces pollution. Sewage beats wind, solar, and geothermal but should be used with them.

      Have heard of using algae oil as a fuel; better than using corn and food sources that people need. I have read somewhere hat it is very efficient, but don't know much about it. Could you be self-sufficient? I mean, if you had a pond or graywater/treatment system at home, how much algae could you grow and how intense is the processing, and how much fuel would you get? Probably doing it as a community effort makes more sense. Experimented with veggie oil a few years back and the ongoing city-wide collection and ongoing filtering really take up way too much of any one individual's time it seemed to me.

        Unfortunately Jacobson does not recommend bio-fuels as they do not solve the negative effects of pollution from combustion


        Report comment

        • SnorkY2K

          I would disagree with that. That is throwing out a solution without allowing for secondary steps. For instance the burning of fuel from algae releases carbon dioxide. For portions burned in stationary generators, the carbon dioxide can be recaptured with calcium oxide in water to form calcium carbonate which can be transported to sun states to be heated by concentrated sun and reused while giving of carbon dioxide to grow more algae in higher concentrations at an algae farm in the sun state.

          It would probably take more consideration for vehicles if they would be able to have cartridges for recapture without impacting mileage. However, in this case more carbon dioxide is extracted for the production and the production is not 100% so more will be used that released so it will be carbon neutral for worst case scenario and drilling already starts at -125% or more

          When used in homes for heat, cartridges could be used. Or the calcium oxide can be used directly with snow or water to heat northern state houses then returned for reprocessing in the sun.

          By using a form of coccolyth forming algae when enough fuel is made, the mining and processing of limestone for making concrete can also be averted.

        much as you could cut your own hair, it does take time and specialization does help society as a whole do more. Unless you had an automated system that would probably be expensive, I do expect that it would not pay off for individuals. However, small coops may be economical. But, on a large scale equipment could be more efficient. By piping spring flood waters and sewage to sun states, we could turn a lot of sunlight into fuel. Sewage systems already in towns would spare the individual homeowners from any change in their daily life and food supply would not be involved.

      In theory it is a good idea, but there are lots of toxics going into sewage.

      Methane is still a carbon fuel, and we need to get off of this suicidal global warming acidifying gas.

      Carbon dioxide is an acid poisonous gas… we are concentrating it to higher and higher amounts.

      This is having an effect on both ocean life and our bones. Acid leaches alkaline minerals out of all living things.

      I agree with you that some good use must be made of the sewage. If it wasn't so poisened with antibiotics & the like nowadays, it would need to go back to the fields – that's how the Chinese kept their soil fertile over thousands of years in ancient times…

        I am already working with a state university helping them with sewage to fuel and sewage to coal. I was absolutely amazed at how far they already had gotten before I helped. The Chinese not only used "night soil", they still do as do many other cultures.

        As far as antibiotics, pharmaceuticals, and household chemicals are concerned there are means to compensate but most communities don't bother since their are little or no regulations and without liability there is no reason for a corporation or even a municipal organization to expand even small amounts of cash for such mitigation.

        Finland and the Netherlands are currently reprocessing sewage to reduce the cost of imported food. The Finns are ahead of NASA when it comes to reprocessing urine into clean water, oxygen, and food.

    Hopefully none will mind this. I'm going to forward my comments from the previous thread to this one.

    If I was one of these people that use all caps I would now.

    It's very common for nukees to throw up the diversionary straw man that clean alternatives cannot cover everyone all of the time. When you hear that watch out. They usually follow that line with a dishonest sleight-of-hand reasoning: since there likely could be some locations where clean alternatives won't work that therefore necessarily means that they are completely off the table, a total failure.

    No, this all-or-nothing assertion makes no sense. What's important is to maximize the use of clean alternatives as much as possible, keeping in mind the fact that every watt generated with clean energy is a watt of dirty left in the ground. If there are locations where, for one reason or another none will work in those areas you can use dirty energy (nuclear last) as a back up to make sure everyone is covered. We already have the infrastructure for dirty. Use it as a last resort rather than today's ass backwards policy of dirty first, clean last if at all – at least until clean can pick up the slack. Everyone covered now.

      Hi Ron – I remember back in 2000 the 4 big (nuclear) energy companies had full-page campaigns in the press over here (I live in Germany) saying that "renewables will never add more than 4% to the energy production."
      Surprisingly (to them) we now have more than 20% and rising fast.

      I don't quite agree though on what you said about areas not able to being covered by renewables. I think that for example for big cities it will be impossible to produce their energy themselves, as it's hard to implement all the infrastructure needed in a limited space.
      For those, it would be possible that surrounding communities produce energy for the big cities….we have small villages in the north of Germany who produce 5 times more energy than they need and feed the rest to the grid to support others and have extra income.

      Wow maybe more clean fuels right now will somehow stop Energy Fuels from drilling into a brand-new uranium mine at the Grand Canyon this Fall. Do they really think there will be an ongoing demand for uranium now? What fools. Just toxify the soil and waters of the indigenous people now living there for a few thousand years so you can make an extra few million before things go under?? I mean, what could possibly be the reasoning behind opening a new uranium mine in the Grand Canyon National Park? Sorry if this is off-topic….

    In developed countries we have the money to begin wholesale conversion to clean alternatives now. Think of a program, a really big one, that has way way overbuilt itself into ridiculous redundancy.

    The military. In the US the war machine continues to garner huge tax dollars ($700 BILLION in 2010 alone) to build yet more bombs and the bombers to deliver them. Come on, It's not like we are in a world war! Talk about welfare, these guys are by far the biggest pig on the public teat. Are we really supposed to believe that they can't get by with last years WMDs or the year before that or the year before that? Then there is another $200 BILLION in wasteful subsidies going to dirty energy which certainly does not need them. It's a scandal.

    Divert this money for a one or a few years to outfitting these countries (by far the biggest consumers of energy in the world) to clean alternatives. Problem solved. But not just that, if we made such a change Peak Oil would fade away in importance. Tragedies like the Gulf Oil Spill and Fukushima would probably be unheard of.

    We have the money and the technology now. All we need is a big political push.

    In the meantime some of us are tired of waiting for affordable alternatives and have been building our own systems. If you want something done right you gotta do it yourself.

    http://www.builditsolar.com/

    This site is hands down the best DYI clean alternative energy site on the web. Lots of ideas and creativity out there. Check it out and build your own!

    Rather than simply building more centralized mega energy plants, instead outfit every house, every inhabited building, home, office, school etc. in the country with it's own source of energy where possible, whether rooftop solar, roof top wind (yep they have them) etc. This would also save on power lost in long distance transmission. Decentralized energy make much more sense. As a side benefit, giving everyone their own source of energy, de-centralizing it, would unchain us from financial slavery to some mega energy plant. No more being subject to arbitrary price increases. No more rolling blackouts. And no need to build or maintain massive infrastructure to transmit that energy to customers many miles away, draining valuable energy in the transmission and blighting the land. And all paid for by diverting money from the military for a couple of years.

    Swords into Plowshares.

      Impressive map.

      We need to remember that, at least in the short term, fossil files would continue to be necessary to power our vehicles (automobile, airplane, ship). That is until we can convert them all over as well.

      But, again, the point is that every watt generated with clean energy is a watt of dirty left in the ground. Even if we only made it a 50% conversion initially that would be a LOT less FFs used. Think of the issues solved with even this quite reasonable changeover. A lot less pollution in the air, land and sea, A lot less dependency on foreign oil resulting in a lot less tension and wars, a lot less greenhouse gases, worries about peak oil going away etc.

      This really is a no-brainer. We know that if we are to survive as a species clean, safe and effective clean alternatives are inevitable. When you realize that something is inevitable you should just do it and get it over with. Continually putting it off only prolongs the pain and increases the risk.

      On top of that, who doesn't want to live in a safer, cleaner freer world? Who doesn't want peace? Who doesn't want to stop worrying about all the peripheral issues surrounding dirty energy? We have to stop kicking this can down the road. We have to stop letting mega corps and the few greed heads who run them run our lives and our one living planet into the ground merely for their short-term financial gain.

      It's gone past ridiculous. Let's get this gorilla off our backs.

    Solar power station in Spain works at night

    "It is the first station in the world that works 24 hours a day, a solar power station that works day and night!" said Santago Arias, technical director of Torresol Energy, which runs the station.

    The mechanism is "very easy to explain," he said: the panels reflect the suns rays on to the tower, transmitting energy at an intensity 1,000 times higher than that of the sun's rays reaching the earth.

    Energy is stored in a vat filled with molten salts at a temperature of more than 500 degrees C (930 F). Those salts are used to produce steam to turn the turbines and produce electricity.

    It is the station's capacity to store energy that makes Gemasolar so different because it allows the plant to transmit power during the night, relying on energy it has accumulated during the day.

    "I use that energy as I see fit, and not as the sun dictates," Arias explained.

    As a result, the plant produces 60 percent more energy than a station without storage capacity because it can work 6,400 hours a year compared to 1,200-2,000 hours for other solar power stations, he said.

    "The amount of energy we produce a year is equal to the consumption of 30,000 Spanish households," Arias said, an annual saving of 30,000 tonnes of CO2.

    New twist on solar cell design

    The key is to the cells high efficiency is its use of small micrometre sized rods of silicon instead of traditional silicon wafers.

    Incoming light bounces back and forth multiple times between the rods in the panel until it's absorbed.

    Small alumina nano-particle reflectors are placed between the rods to ensure the light is guided as efficiently as possible.

    The scientists claim up to 85% of usable sunlight is absorbed by the new panels, compared to approximately 17% efficiency with current commerically available solar cells.

      You're doing very well B&B. Just figured ours (three people, + dog, cat and horse – admittedly the latter three don't use much) for one year. 7335 Kwh for 2011, with by far the highest in usage in the winter. It get's cold here. Rather than use gas we use space heaters.

      Our contribution is a solar water heater which works well from April/May to the beginning of November, seven out of 12 month. We are on propane and since building it we've be able to cut our use of it to a fraction of what we used before, which is very nice considering the price of gas these days.

    Backfilling Nuclear Shutdowns With Efficiency And Renewables In Japan, Germany And California?

    Electric utilities and policymakers in Japan and Germany have been scrambling for months to find ways to compensate for nuclear power plants shut down in the aftermath of Fukushima.

    In both instances, fossil fuels are part of the stopgap solution to offset the declines in nuclear generation in the short term, but longer-term energy policies are shifting definitively toward efficiency and renewables. Now, the unexpected and indefinite shutdown of both units at the San Onofre Nuclear Generating Station in Southern California has raised questions about California’s short-term electricity supply options and long-term contingency plans.

    Corporate Japan is starting to "get it"

    Roundup: Companies rush to set up solar plants in western Japan

    In July, Japan will launch a new feed-in-tariff scheme for renewable energy, expecting to encourage both solar and wind power projects in the country.

    Among them, Japanese electronics giant Kyocera Corporation earlier this month unveiled plans to build Japan's largest solar plant in the country's southern city of Kagoshima. Kyocera said the new project would be jointly undertaken with heavy machinery manufacturer IHI Corporation and Mizuho Corporate Bank which will devise a financing plan for the project.

    The three companies agreed to construct the 70-megawatte solar power plant, The total cost of the project is estimated at 25 billion yen (about 309 million U.S. dollars). The planned site of the solar plant is approximately 1,270,000 square meters, and construction is expected to start this July.

    "As long as the new program to utilize renewable resources within the national electricity grid brings a lot to the developers and people, 'mega-solar' can be the start of an effort to seek much safer way of energy supply in the country," Nomura added.

      Hi Jebus, that's good news! There's still one thing I don't quite get: 70 MW is equivalent to 14 windmills of the newest generation.
      If I had to decide how to use Japan's limited resources of land, I surely would put solar on existing roofs and put up windmills. On 1,27 square kilometers you could put up some windmills and still use the land they're on for agriculture.
      Just wondering!

        Simple…
        If you give the people their own energy generation options, you loose control of the revenue. Build a solar plant, your corporate self, and you keep control of revenue.
        Again, it's all about the revenue!

            If we all, individually, invested into our own, currently available, energy solutions, the cost of these giant monopolized energy plants would far outweigh the dwindiling revenuses they would recieve from them and the cost of investing in individual solutions would drop next to nothing. Economies of collective scale. Convert just all of our lighting to low voltage electricity, generated locally, and you would eliminate a large percentage of the worlds energy issues.

  • Wind turbines are inefficient and expensive, but there are better ways of harnessing the plentiful power in wind:

    http://www.kitegen.com/en/technology/details/

    Pros:

    1. provides more power than nukes or other power plants ("kites can extract more energy from the no-fly zone above a typical nuclear power plant than what the plant itself produces").

    2. it is actually safe (kites are just pieces of fabric floating in the wind).

    3. can be built almost anywhere (there is almost always enough wind at 1km altitude, even when there is no wind at ground level).

    4. way cheaper kw/h than anything else (see site).

    5. 100% renewable and clean.

    Cons:

    -. can't think of any serious downside, can you?

    Replace current nuke plants with these, then add more as needed. I am not associated with Kitegen, just trying to get people to realize that the energy problem is solved already, if enough hear about this.

      Soooo…the scientific papers are from 2007, the press says it might start in 2009 – now it's 2012, is there one of the systems up and running?
      On paper, it's a charming idea, though I'm a bit worried for maintenance (lots of moving parts, entangled ropes,…), and if people are worried about killed birds in regular windmills, I wonder what those would say to the kite system…

      I know there's always room for improvement, but I wouldn't say that today's windmills are "inefficient". They have a steep development curve.

      • windmills are inefficient because building a giant pedestal that can resist storms is expensive, the giant blades are expensive, maintenance of the generators and the associated heavy machinery perched at an inconvenient height is expensive, and with all that effort they're often not turning, either from too little wind or from being out of order.

        With kites there is no pedestal, no blades, and the generators are conveniently located on the ground. Thus they cost just a fraction of what windmills cost. And kites can reach 10 times higher than windmills where the wind is much stronger and much more continuously available, they can be producing megawatts of electricity even while the towers underneath are sitting still.

        Kites have made windmills obsolete. My guess as to why there aren't kite farms everywhere yet is that most people are afraid of change and will blindly oppose it even when it's good for them. Look at your own comment about tangled ropes, or the alleged problems with birds and windmills. How relevant is that in a world where we have to contend with the risks of nuclear plants?

      Kites provide more than one way to generate power. Besides extracting power from air movement they can also tap a larger force which is differential static charge. It does not have to be lightning and by tapping it lightning strikes could also be reduced. By adding wind and direct power production from kites, they would be very very efficient. (I am partial to kites. Franklin produced his power for an important experiment from kites) We would have no aircraft if the Wright brothers did not love kites

    First the good news: If you live near the ocean, this project may interest you. It's a government-supported tidal power project in Nova Scotia, Canada.

    http://www.fundytidal.com/

    A wind farm has recently been established in the same area:

    http://eonwind.com/projects/?p=54&show=slide

    Now the bad news: about 45 miles away from these projects, on the opposite shore of this same body of water (Bay of Fundy), the government of another Canadian province, New Brunswick, is refurbishing and restarting a rust-bucket nuke plant (Point LePreau). Ironically, the Nova Scotia residents are downwind from it much of the time.

      We need a term to replace downwinder since the whole globe eventually shares the pollution. I suggest that we say "same ballers" since we are all on the same planet.

      I had to testify in an open hearing for a windmill farm. Many religious fundamentalists have really got something against windfarms and pay for experts to give testimony against them to come from far away.

        Congratulations on the windfarms. In my part of the world, there are vigorous murky objections to wind power because "some outsiders will make a lot of money from this". I always figured that was enemy action from vested interests in other power sources – generic FUD.

            The fundamentalists showed up with about a hundred home schooled children and claimed that the windfarm would kill all or their children. They had experts from Connecticut that "proved" that windfarms caused spontaneous abortions in llamas and low frequency sound induced insanity. I was able to discredit one of their witnesses who claimed that the windmills just north of Ames, Iowa created a low frequency sound at least every half hour that would be harmful to everyone living in the area. I received my undergraduate degree in Ames, Iowa and also had family servicing the main Union Pacific cross continental railroad tracks there. My questioning their witness if he accounted for the subsonic train noise captured in the Skunk river and Boone river valleys. The trains can be miles long and can be heard over ten miles away in the audible range. Several of the county board members later stated that that was the testimony that ruined the credibility of the witness for the anti-windfarm side.
            My supporters were some local environmentalists, a union that would build the windfarm, and surprisingly a nuclear power company that was switching from investments in nuclear to wind.

                Fundamentalist Christians tend to be strongly rightwing politically. The Republican party and also Libertarians are pretty strongly anti-environmental. Their ideology has been pretty much appropriated by the corrupt corporate world which works hard to destroy environmental regulation. It's ironic since fundies love to tout "God's glorious creation" when pushing creationism in public schools.

                Also, as SnorkY2K intimated, they are focused on heaven. They believe the Bible says that God is going to destroy the earth, and since they think they are going to heaven anyway they simply don't see the necessity in preserving this planet. It's destined by God for destruction and they don't wan to do anything against that. Besides this, they'e always had a view of nature from their interpretation of the Bible that it exists simply for man's pleasure.

                If you express any interest in conservation they'll accuse you of nature worship.

          "Solar Credits is a mechanism within the SRES scheme that provides additional support to households, businesses and community groups that install small-scale solar photovoltaics (PV or solar panels), wind and hydro electricity systems by multiplying the number of small-scale technology certificates (STCs) able to be created for eligible installations."

          So, when a home is vacant, with no one using any devices, it can possibly make money by 'pushing' power back into the grid.

    A question I have about renewables, batteries, production etc …

    For a 'device', there is a need to consider the entire 'dust to dust' process.

    What energy/resources/carbon emissions went into producing the entire 'device', then the ongoing/operational costs, then the final decommissioning of said device.

    For example, hybrid cars might look like they are doing a great job for the environment, but what went into the production of the batteries .. what rare and precious metals were consumed, what rainforest was depleted to mine and extract those metals ?

    The hybrid car uses electricity – how was that electricity produced – nuke ? – solar, wind, coal ?

    And then there is the 'recycling' of the batteries, if it's done correctly.. and what emmisions/contamination will occur at that stage?

    Don't get me wrong, I'm not having a go at electric cars .. I just want to raise the question and get a better idea of the holistic energy/resources of a device.

    There is a need to watch out for subsidies as well .. a product or service may be discounted due to a false economy in the supply chain. But it doesn't reflect the true 'cost'.

    Batteries are an ongoing concern for me – their exotic metals can be very nasty. But that's another thread.

    dust to dust starts with the road that the car drives on. Huge production of carbon dioxide comes from cooking off the limestone to make concrete. The quicklime soaks up carbon dioxide later but there is a tremendous amount of energy used to make the heat that is not recovered. Concentrated solar could do it as well and the carbon dioxide captured to grow algae for making fuel. Doing so would have a tremendous net reduction of atmospheric carbon dioxide.

      Good point about the road itself.

      funny, i'd been lightly pondering roads and concrete and lime over the last few days .. not sure why. I was kind of wondering where it's all coming from, when will it run out, how it will be recycled.

      but anyway… that is a major thread of it's own as well.. the construction industry. But yes, apply solar at the contruction stages would be fantastic – the 'base load' problem is not as prevalent, as some of these services do not need to run 24/7. there are so many ways power can be decentralised and recategorised to provide something more attune with the need at the time.

      but, in general, I was refering 'simply' to the discrete devices themselves. oh, what a web we've weaved. so i'm not going down that 'road' :)

        Calcium carbonate (limestone) can be produced by coccolith generating algae grown in sewage and sunlight. Why mine when it can be done without burning fuel for heavy mining equipment? Many midwestern US towns are surrounded by big holes where the limestone came from. Most of Illinois' original forest went to heating limestone kilns to make quicklime and not for houses or paper.

        However, I am more for centralizing processing to states such as California through Texas where there is plenty of sun that is fairly constant and easily concentrated to high temperatures. Also, with scale and size, means of storing energy from sunlight becomes economical.

      There are solar light poles available. However, that is another topic on its own for we have a wasteful light problem. Do we really need so much light? Can we turn the lights on only when a car or people are approaching? Can we replace the lights with luminescent materials? Can we reduce the massive amount of power used by using lights more conservatively?

      Lights were first pushed by power companies as were electric water pumps. Farmers in the 50's and 60's removed their windmills and put up big lights more to keep up with the Jones' than anything else. I could see electric water pump for the house and a backup to wind. But, why not use wind when available? Want to get rid of nuclear? Try reducing the need.

    Solar Energy Field renewable energy producing structure for deserts

    The Solar Energy Field by eco-conscious architect Michael Jantzen has been inspired by the conceptual symbolic representation of the micro energetic interaction between photons of sunlight and the release of electrons with photovoltaic cells, which in turn produces electricity. This energetic interaction is symbolically represented as a large, pragmatic, scalable, abstract, three dimensional, stimulating and challenging form, capable of capturing energy from the sun, and converting it into electricity for the local community.

    The basic structure would be constructed from a series of prefabricated panels, each fitted with a steel support frame, and covered with a colored concrete composite skin. These panels can be added or removed to scale the structure up or down and/or to change the shape at any time.

    The architect believes that during a sunny day, the solar panels will be able to generate up to 10,000W of electrical power for the local grid. In addition to generating renewable energy, the structure will also be used as an oasis sheltering visitors from the hot sun. Some of the lower panels of the structure fold out in different ways in order to provide places to sit.

    Old Electric Car Batteries to Find Second Life on the Power Grid

    Electric car batteries have up to 70% capacity remaining after 10 years of use. This allows them to be used beyond the lifetime of the vehicle for applications, and smart grids can take advantage of their capacity to store intermittent renewable energy.

    I've already written about how they could be used to store wind power to reduce the intermittency problem, but a new partnership between Nissan North-America, ABB, 4R Energy, and Sumitomo Corporation of America believes that used electric car batteries (Nissan LEAF ones, in this case) could be used for residential and commercial energy storage, even acting as emergency back-up during natural disasters like last year's earthquake and tsunami in Japan.

    The partners plan to develop a LEAF battery storage prototype with a capacity of at least 50 kilowatt hours (kWh), enough to supply 15 average homes with electricity for two hours. I assume that if that works out well, they'll scale it up, possibly even up to the multi-megawatt-hour scale, which would make it really useful in emergencies and to store solar or wind power.

    Wind Turbine Makes 1,000 Liters of Clean Water a Day in the Desert
    A cool new concept being tested in the Abu Dhabi desert uses a wind turbine to condense water from the air and pump it into storage tanks for filtration and purification.
    A prototype of the technology has been installed in Abu Dhabi since October and has been capable of producing 500 to 800 liters of clean water a day from the dry desert air. Eole Water says that volume can increase to 1,000 liters a day with a tower-top system. The system requires wind speeds of 15 miles per hour or higher to produce water.

      This link is from the article above about the simple process to get water from the air.

      EWA Squeezes Water From Thin Air, Like In Old Biblical Times
      EWA (which stands for Extraction of Water from Air), has developed a clean technology that extracts water from the air, while using little energy in the process. The key they say is in its unique water adsorption technology – which employs a solid desiccant to trap the water – and a special energy saving condenser that reuses more than 85 percent of the energy input to the system.

      The company, which was founded in 2006, is based on nine years of research by Etan Bar, a former researcher at Ben Gurion University. The company now has representatives in the US, India, Jordan, Cyprus, Australia and West Africa where EWA is helping farmers generate carbon credits, on top of providing them with clean water for drinking and irrigating their crops.

      To compare – according to the US-based Global Policy Forum, the average American household consumes about 480 cubic meters (127 thousand gallons) of water during a year. While homeowners in Washington D.C. pay about $350 a year (72 cents per cubic meter), buying the same amount of water in the slums of Guatemala City would cost about $2,000.

    somebody was inquiring if there were any programs / providers for actual solar-isolation data. There is but it would appear that it's for the big-boys (institutional/architectural). Still, that shouldn't prevent someone from inquiring as to when they'll be providing this kind of data for the little guys like us…

    Hmm. Is the White House listening?

    The other day (4/29) in this thread I recommended using money going to the military to instead fund the purchase of point-of-use alternative energy (e.g. rooftop solar, rooftop wind etc.) so that everyone can finally have their own and we can finally get off dirty energy.

    I just happened on an article in which President Obama proposed something very similar the day after.

    "American workers built this country, and now we need American workers to rebuild this country. That’s what we need. (Applause.) It is time we take some of the money that we spend on wars, use half of it to pay down our debt, and then use the rest of it to do some nation-building right here at home. (Applause.) There is work to be done. There are workers ready to do it, and you guys can help lead the way."

    http://www.telegraph.co.uk/news/worldnews/barackobama/9237453/Barack-Obama-we-need-to-do-nation-building-right-here-at-home.html

    So okay, the concept of diverting the money being wasted on the purchase of ever more military garbage to better uses domestically is now officially valid. My question is, whatever happened to Obama's "Green Economy"? Wouldn't using the money to outfit every home, office, school, hospital etc. in the country with a clean energy alternative be a logical extension of Obama's above proposal?

    Swords into Plowshares. Spread the word.

    it's important that we keep an eye on how this industry is growing and how they'll usurp it to meet their ends; like everything else in history…

    TWO THOUSAND FIVE HUNDRED WATTS from two solar panels on a custom golf cart that can power your home, venture into the woods to cut firewood with your ELECTRIC chainsaw, or just go and kick butt @ a tractor pull and blow everybodies mind!!

          @selfsovereign" quoting power output from battery storage of PV generated electricity is misleading. You could take a trickle charger panel that only produces 10 watts in bright sunlight to charge a battery. When the battery's topped-off, it may be capable of providing a five-hundred-watts for the first hour's use. Would that mean the solar-panel provides five-hundred-watts of power? No. The configured system is but not the actual solar panel itself. It's important people not get snookered by misleading numbers. Which I've seen throw-about lately by some – less reputable – companies…

            Hi AFTERSHOCK,

            Respectfully agree to disagree.

            The sucessful, creative integration of off the shelf parts to deliver 2,500 watts of A/C power is NOT misleading, it's simply brilliant.
            As you know, having watched the video, the first concept vehicle (there are 3 different vehicles featured) would provide far more than 2,500 watts of A/C, if there was an off the shelf inverter compatable with the tractors voltage configuration.

            The video provides what my post describes.

    This is going to be a really important issue. When you're talking leases, you're talking bank funding. The details of how this type of funding evolves is extremely important to all parties. We know the same people who control the funding towards centralized energy (nuclear, coal and gas) see the writing on the wall and need to develop financial instruments to cover both the costs of cleaning up the nuclear mess, while also continuing their control (indenturing) of the people. If we don't want to discover ten years from now that the promised return of renewable energy is only going into the pockets of the banks (like everything else these days), then the concept of leasing PV / Wind systems for use on residential sites needs watching…
