A German inventor has come up with the technology that will power your car on fuel derived from dead cats.Christian Koch, 55, has angered animal rights people with his alternative fuel which is made from a secret recipe of garbage, mashed-up moggies, and other ingredients.He said that his normal diesel-powered car has clocked 170,000 kilometres (106,000 miles) on pussy power without any major catastrophe.His company "Alphakat GmbH", says his patented "KDV 500" machine can produce "bio-diesel" fuel at about 23 euro cents (30 cents) a litre, which is about one-fifth the price at petrol stations now.It takes 20 dead cats added to the mix to produce enough fuel to fill up a 50-litre (11 gallon) tank. We're just one step closer to Mr. Fusion, the same technology used in the movie "Back to the Future".
