The Heads on Fire Community

so today while i was listening to the head of H design talk i had a few ideas

the first was

a portable cooking system based on a very durable rubber, so my idea was
we could use this plastic make a kinda furnace design that is very portable with a metal tray and smoke filtration i have a diagram i shall upload later

other ideas

use compression of shrubbery and paper to make coal like burning substance for portable cooker

use high level magnification to light stoves in areas like Africa

use 2 irons and a solar panel and a metal peice to make a $24 stove top that is portable and can be broken down

also add a filter to the hippo roller
