That said, I'm working on a project I hope will be a game changer for producer gas production. I'm doing it using an external flame, almost exactly the same way folks who make charcoal do it. Instead of venting the producer gas into the air or routing it to a burner beneath the chamber the way charcoal makers do, I'm attempting to capture it and "clean" it up using the external flame to heat a reduction chamber. This should allow gasification of ANY gasifyable material using just one gasifier. I'll update my progress in a thread titled 'Rocket Stove Gasifier'.
My ultimate goal is to efficiently gasify landfill-destined waste. Reduce the amount of waste going into landfills by cleanly turning it into electricity by converting it to producer gas to fuel a generator.
Since compressing the gas is out, I'm going to store it in big innertubes. I'll weigh down the stack of innertubes in order to make pressure.
Please feel free to look over this experiment and comment.

If the heat from the rocket stove isn't enough, we're going to try to burn charcoal in the stove, since that's our byproduct anyway. If we melt our stove, we'll at least know we have the necessary heat to crack tar.
Turns out a member here posted about the answer to how you gasify not only wood, but any other organic feedstock as well. It was a post about charcoal gasifiers, started by---you, Marcos, if I remember correctly. I thought it was brilliant and saw the potential for gasification of just about any organic waste one might have locally available.
Marcos, do you know if I'm going to run into any trouble storing producer gas in a stack of innertubes? Does it go " bad" after a set amount of time? Will it degrade the rubber quickly, assuming our stored gas is clean? What is your preferred storage method?
If my partner and I fail to build a workable multi-fuel gasifier the way we're attempting now, we're going to move on the charcoal gasifier and making charcoal from municipal and agricultural waste briquettes.
Bill Bianchi wrote:The water chiller interests me very much. Electricity, transportation fuel, home heating, and hot water heating are fairly simple to handle with passive and active systems; gasification, fuel alcohol still, solar panels, wind gadgets, TEG technology.
AC has thrown me for a loop, though. I've looked into absorpsion cycle chillers/refrigerators/freezers/ice makers. While possible, there aren't many products for sale that use this for air conditioning, at least so far as my searches have gone. I've been wracking my brain for a while on this. Even tried to figure out a small, personal AC system designed to cool off one or two people, rather than the whole house. Still think it would use less energy overall to cool the people down rather than a whole house, or even one room, but I'm not sure how to do it yet, or even if it's possible or viable.
You gave me a name to look up in another thread. I'll be looking him up today.
Bill Bianchi wrote:You are miles ahead of me on this. The best I've come up with so far is a possible portable, single person cooler made from a small fan, styrofoam beer cooler, and a pipe.
Fill cooler with water. Put pipe in the water, both ends of the pipe coming out two holes cut into the lid. No water gets inside the pipe as both ends remain above the waterline at all times. Stick it in the freezer until you have a block of ice with a pipe through the middle. Take it out, press the lid down, put the fan on one end of the pipe, and aim the other end at yourself.
For constant cooling, make two of them, so one can be freezing into ice while the one in use melts.
LOL, that's my redneck approach for single person cooling. Goofy, but the extra load put on the freezer might be less than running an AC unit to cool a room---maybe. The only thing I can think to do to make this not cost money is to run an absorpsion freezer on homemade methane or producer gas.
Your idea sounds better than mine. Wish I knew enough to try it. If any DIY plans exist, I would be interested in getting ahold of them.
