Figuring out what to do with the gas

created by the pyrolysis process is the real challenge.

Unfortunately, since I am a lawyer not a scientist, I can't help much with the design. But I had envisioned a ceramic based stove, potentially made out of pottery for third world applications. Even better would be a stove made out of something like soapstone for first world applications.

Modern wood stoves burn exceptionally clean, combusting the gas with catalytic converters or secondary chambers that get intensely hot.

I have kind of envisioned a three chambered stove/barbecue/smoker. The first chamber would have a small amount of sacrificial starter woodstock. The second chamber would contain woodstock for charcoal and the third chamber would be an oven for cooking/barbecuing/smoking. Obviously, the gases produced in the second chamber need to be redirected into the first chamber where they ignite and keep the oven going. Maybe catalytics are necessary here -- maybe not.

But that is what I have envisioned.

If they can make woodburning stoves that recombust all the gases, why not take this technology and use it for making charcoal in our homes?

After all, heating and cooling our homes takes up about 60% of our energy requirements, depending upon location.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
