During my initial research into charcoal stoves, I was given the website for The Guatemala Bolck Stove, which uses wood for its fuel source. Charcoal burns a bit differently. I have a modified design for the block stove with an added sheet metal insert. Check out the pictures below.
The Block Stove is for use inside the Haitian homes. It will be the width of 2 blocks plus the insert. The height will be 4 blocks high, approximately 32". The fumes from the charcoal will be vented directly out side.
