All my net surfing research has shown that large scale production of BioD is a big ass suck on the government titty boondoggle. http://www.ams.usda.gov/mnreports/lswagenergy.pdf I looked at all the tax breaks and incentives they get to offset the actual cost of BioD. This is on the same level of Solyndra and other "Green Energy" jobs that has screwed taxpayers. The only thing government has done has made it more difficult for home cookers to fine the yellow grease (WVO) needed. What restaurants use to pay to have removed now can be sold to the highest bidder who has arranged tax breaks to get it.
