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.
