Forget the tiger - put sheep urine in your tank

Guardian Unlimited | Life | Forget the tiger - put sheep urine in your tank:

"The urine is collected by the fertiliser industry from farmyard waste and refined into pure urea, which is then sold on to be used in the green engine technology. Ammonia from the urea reacts with nitrous oxides in the exhaust fumes and converts them to nitrogen gas and water, which is released as steam."

What is going on in the UK? If nothing else they are thinking outside the square. I guess it's better to run on sheep wee than oil in this day and age. I seem to remember we were doing things with pig poo to run generators or something and then there's the famous bit in the Day of the Triffids where they fly the plane on sugar. So , let's forget the oil and the daily price of the barrel. Let's take the bull by the horns and go fully organic with fuel. What a hoot. We could fill up at the bowsers on donkey wee, camel wee...run our homes on pig poo.Heaps more fun than oil. Can you imagine the branding, logos and ads?
