The MIDGE is the simplest, cheapest gasifier campstove you can make.
It's name means "Modified Inverted Downdraft Gasifier Experiment"
Arthur Knoll (the inventor of this stove I assume?) came up with a .PDF explaining how to build it:
I was very impressed with it after building one.
This could have been built 50+ years ago and would have been a revolution in campstoves.
Literally *anyone* can build one.
3 tin cans and (10x) #10/32 inch screws are all that's needed.
I decided to take these plans and make detailed YouTube build instruction videos.

These videos show you far more than most videos out there.
Most neglect to show how to *properly* prepare the wood for best performance from these stoves.
When around "home base" or car camping, I fuel my MIDGE with hardwood pellets exclusively.
A MIDGE will run 25 minutes on a 3/4 can load of wood pellets.
I've cooked rice for 4 people and cheeseburgers in a large frying pan with my MIDGE.
I rarely use my MSR XGK all fuel expedition stove anymore since building a MIDGE.
Step 1: MIDGE Sketchup Model
MIDGE Gasifier Campstove by KK - 3D Warehouse - http://is.gd/WVdy5E
It's an exact scale 3D model of the cans.
Transparent X-Ray view shows the inner alignment of the cans.
I've changed the design slightly (6 main airholes and 6 support screws with nuts)
Main screws are 10-32 x 1 1/2"
Pot standoff screws are 10-32 x 3/4"
