My little project

[J.B. Simpson]

One of the serious drawbacks to biofuels is their viscosity. BioDiesel as an example will gel at a higher temperature than regular diesel. This makes it's use in colder climates very very limited. The only way to prevent it from gelling (besides heating it) is to "cut" it with regular diesel. In my area most users will have 80-90% diesel with the remainder BioDiesel.

Users of "waste" cooking oil derived BioDiesel have problems with not only gelling but a formation of a hardened like what you will see on a heavily used and seldom cleaned deep fryer. In some areas the "bio" fuels will work, but not in all.

Just my $.02, take it as you will.

Another quick $.02.

If/When BioFuels become popular and demand increases for the crops to produce them a shortage of food crops will follow. A farmer who makes very little raising standard grain crops would plant his entire farm into a crop that has a higher value and is easier to raise. It is a tricky road to travel. For every positive aspect there will be a negative that is alrready known or that will rear its ugly head when the time comes.
