Tom, have you been working with Peter, off-list??

I have always wanted to build one of these puppies but fuel it with producer 
gas. Check out the below link:

Maybe the producer gas would not need to be super clean?

Make a rotary prime mover: Cement a a good sized pipe in the ground. At the 
top place a bearing. Next picture a rotor blade on top of the pipe and both 
are hollow to allow the producer gas to flow to the pulse engines mounted at 
the ends of the rotor. Next incorporate, from the wind mill people, an 
axial-flux PM alternator. Now you can make your charcoal and burn the off 
gasses in this pulse-jet rotary axial-flux generator!

I've also thought about mounting two of these on my jeep with a woodgas 
generator. Start off with the stock gasoline and engine and once up to speed 
switch over to the pulse-jet/woodgas unit. Hey, make charcoal as you drive 
and discourage tailgaters...


PLEASE, tell us more about your pulse-jet dryer.........



Jeff
