permaculture

Scott, do you have any old copies of the Permaculture International journal 
sitting around? There was a company that advertised in there that sold 
various types of chippers that hooked up to your PTO shaft. 
Seems like that would be the simplest way to employ biodiesel in chipping - 
with a diesel tractor,  if you actually have one. Seems like even developing 
countries they aren't uncommon. Of course, you wouldn't need to do any 
conversions of your tractor or the chipper if you were to use biodiesel - but 
you would need to convert your waste vegetable oil (WVO) into a methyl ester, 
using relatively expensive and scary chemicals. Or you could modify the fuel 
system of your tractor so that after starting it on diesel or biodiesel you 
could run it on WVO. Here is a cool guy in Minnesota who sells some cheap 
plans for building components that will let you run WVO in an older style 
Indirect Injection Diesel: http://danalinscott.netfirms.com/ . The plans are 
like, under $50 for everything you will need, and even if you use all new 
parts to build his conversion you can make one for two or three hundred 
dollars - about half what you would pay for a "commercial" kit. Of course, 
you can scrounge recycled parts and make it all a lot cheaper.
