Bullshit on the veggie power...

more like the "chicken-ish" smell near cottonseed refineries.
better than petrol diesel by a long shot, in my nose.
Plus it uses another waste product.

 

Depends on what the region needs.
In Colorado, I often have days where we cannot use fireplaces (this is suburban/urban mix), so with less particulate matter going out, it would be an improvement here.
The mustard relative grown in Wyoming and Nebraska and a few Colorado counties for its high oil output (these are farms co-oping with Blue Sun Bio-D) is a cover crop. So, it's a crop usually plowed under, or more common;ly here, harvested and trashed. No "market crop" time or land is taken from production. plus it's a bloody weed and nothing seems to kill it, so no forest land needs to be appropriated for its growth.
Using industrial waste for fuel still makes a lot of sense to me, as well.
Maybe we will (gasp) diversify the fuels we are dependent upon so that all fuels can drop in price.
