Alternative Diesel Gaining Traction

I found "Biodiesel to drive up the price of cooking oil" (note, this article is from a computer news web site) very hopeful for diesel cars and diesel fuel alternatives.

paired with this is a research from UC Riverside: "From sludge to cheap and clean diesel" where trash is converted into very clean diesel for about $1 per gallon. Cost of distribution would add some amount to that cost but still should be cheaper than what we pay for regular gas!
