PYROLYSIS SOLAR PYROLYSIS GREEN GARBAGE DISPOSAL COAL ASH ALTERNATIVE FRESNEL LENS This is an idea I have had for a long time. Solar power. This offers an option for coal fire plants reducing the byproduct of coal ash disposal sites. This can be used for GREEN ENERGY power production. Many people do not realize that coal ash is used in products they have in their house. While is is trapped somewhat safely in some cement products, the high levels of heavy metals may present in household items.

    Super video! But the pyrolytic gasses are combustible, why not save them for use in cars, home heating or cooking?

    Burning precious resources and converting them into toxic gases and ashes? Why do you produce garbage in the first place? Its not technology, its strategy. The only thing people is listening to is how to solve a problem instead of working on how to avoid the problem. I.e. PET bottles. A complete idiotic thing. Even harmful for your health (endocrine reaction). Whats wrong about glass? I tell you: No waste. Did consumers chose PET? No.

    oh my god, just think of the CO2 that would make. Not in my back yard

    You capture these gases and use them for combustion. The gas process is complex and is done in many process already. This is designed for large scale not backyard. Also simply burning or staring your BBQ pit is many times more destructive to the environment. Char, the black stuff I made in this video is sequestered carbon.

    Excellent. I have been looking into possible methods of a slow pyrolysis system to provide biochar for safe, earth friendly, biowaste recycling, especially for my agricultural and organic home waste. The systems I’ve been looking at simply aren’t practical for non-commercial use, and a growing number of farmers want the biochar to free ourselves from fertilizers and the cost our agri waste. I can modify this for small scale use, and solar powered is even better.
    Kudos; This is excellent.

    wow u guys make the coolest vids

    🙂 Thank you.

    good vid…lets do it!

    I use dry grass clippings to make bio char, you heat a metal paint can with a lid. You must have a way for the gas to escape! This stuff is good for the garden. The down side is that it smells worse than anything you can imagine.
    Try it with wood chunks and you will find the best BBQ charcoal you ever used.
    I don’t need to use the underwater method just heat things without much air and you get charcoal and not ash.

    Very cool! I’ve never heard of biochar. It seems like a really nifty alternative.
    Thanks, Greenpowerscience!

    Wow, this is excellent. Having built a few solar ovens myself I wondered whether it would be a viable way of producing biochar – and now you’ve proven the concept! Well done!

    awesome. you could coil a hose in the water to heat the water running through it and connect that to your hot water heater. the water would already be warm entering the hot water heater, so, less work for your hot water heater, and less electricity being used.

    you should be able to light the gas coming out of the shavings.its called wood gas

  15. #15 by cavemanboborj at June 26th, 2009

    DUDE! The escaping gas is the most useful part of the process! That gas is commonly called syngas. It’s a mixture of methane, hydrogen, carbon monoxide and water vapour, along long chain hydrocarbons–tars.

    What you want to do is pass that gas through another cool container to condense all the tars out of it, then use it to run a normal piston-cylinder engine. Like a lawn mower or a small generator!

    Stop calling you ideas crazy

    porfavor traduscan al español , gracias…

    Hey Dan, they’re talking about biochar being the best way to sequester carbon and improve soils fertility … but all the biochar ovens i’ve seen seem to use conventional energy to heat the biomass … looks like your solar method releases zero carbon into the air…. do you think it could be up-scaled to make biochar on mass ?

  19. #19 by GREENPOWERSCIENCE at July 16th, 2009

    Yes, I think it it would be a better hybrid alternative to speed up the process while reducing emissions. The vent gasses are combustible.

    holy damn that’s genious!!!

  21. #21 by Mylitla at September 5th, 2009

    The water bath is a waste of energy. Use a suitable material for the retorte in the first place and skip the water bath. By all means capture and use the escaping gas, THAT is the whole purpose of pyrolysys. That stuff you are wasting can be a substitute for OIL if processed further.

  22. #22 by Way2Smart22 at September 17th, 2009

    what is the definition of ‘retorte’ as you used it in your post?

  23. #23 by royishan at September 28th, 2009

    But what happens in the case of wet garbage. In cases where the garbage is fresh out of homes then how does one convert it into char? Can the same process be used for such waste, or does one need to wait for it to dry first and then dispose it??

  24. #24 by GREENPOWERSCIENCE at September 28th, 2009

    The water vapor exits first. It does not have to be dry, just not soaking wet. Similar methods used for incineration, they usually do a mild gravity dry or compression first.

    Got it..!! Thank you..! 🙂
