A Tiger In Your Tank

Some years ago Exxon and its predecessor advertised their gasoline as "putting a Tiger in your tank". Now a German scientist is trying to do just that:

A German inventor says he's found a way to make cheap diesel fuel out of dead cats.

Dr Christian Koch, 55, from Kleinhartmannsdorf, said his method uses old tyres, weeds and animal cadavers.

They are heated up to 300 Celsius to filter out hydrocarbon which is then turned into diesel by a catalytic converter.

He said the resulting "high quality bio-diesel" costs just 15 pence per litre.

Koch said the cadaver of a fully grown cat can produce 2.5 litres of fuel - meaning around 20 cats are needed for a full tank.

He said: "I tank my car with my own diesel mixture and have driven it for 105,000 miles without any problems."

Annelise Krauss of the Dresden Animal Protection Association blasted Koch's new diesel though, saying: "This is as bad as experimenting on animals."

That'll make your engine purr.
