DIY: Make your own biodiesel for fun and profit

Etruk, a UK company, is selling a do it yourself biodiesel machine that will turn your fry grease into fuel for just pennies a gallon! For just £895 ($1,821) you can buy its smallest distiller that turns out 40-liter batches. Etruk's site says it's perfect for keeping a single car fueled. Or you can step up to the largest machine, which costs £2,095 ($4,265) and churns out 150 liters of fuel at a time. Just the right amount says the site for someone who wants to start their own biodiesel fueling station.
While it's legal for Brits to make their own highly-flammable fuel right in their own back yards, it's not clear how U.S. authorities would react. So before you go ordering one of these, check your state and local laws.
