One from Jenny from the unused DVD questions.

Might be better used in the series.

What natural substance is being used in Winchester to clean up harmful emissions from bus engines?

Answer : Sheep urine.

The Stagecoach company has fitted a bus in Winchester with a tank of sheep urine. The waste is sprayed into exhaust fumes to reduce emissions of harmful nitrous oxides.
The urine is collected by the fertilizer industry from farmyard waste and refined into pure urea, which is then sold to be used in the new engine. 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.

LordWilson posted this on the B forum, and I couldn't resist it!

Question: Who were the biggest losers of the last world cup?

Forfeit: Wayne Rooney, England

Answer: The trees

This was the story about football fans urinating in bushes in Berlin, causing very high levels of ammonia and supposedly poisoning trees. The Germans called it the "Pinkelproblem"

Quote:

Thousands of fans have been resorting to emergency measures: peeing in the surrounding bushes.

This has prompted one scientist to warn that the Tiergarten's plant and tree life is in serious danger of dying because of the 100,000 litres of (almost exclusively male) urine being dumped on it every day. 'The urea sinks into the ground as ammonia. In small quantities this is a good fertiliser. But too much acidity leads to over-fertilisation and is bad for the soil,' biologist Tilman Lamparter, from Berlin's Free University, warned.

Anyone for icecream?

Quote:
Researchers at the state-run International Medical Center of Japan said they have succeeded, in co-operation with Sekisui Chemical Co, in making the smell of vanilla from cow dung.

Compared with usual vanilla, 'this component is exactly the same, but it would be difficult for people to accept it in food, given the recent rules of disclosing the origins of ingredients,' she said.

SEOUL (AFP)—South Korea Wednesday opened its first domestic-designed power plant using animal waste for fuel as part of efforts to provide a new source of evironmentally friendly energy, officials said.

The 30-kilowatt plant in Icheon, 60 kilometers (36 miles) southeast of Seoul, can process 20 tons of animal waste a day, the ministry of commerce, energy and industry said.

Here are some cloacas, which do a lot of the waste digestion in us.

Personally, mine is a little more compact than these models. Have a read of the essays under the 'resources' link, some of which contain a terrific assortment of crap.

A dung-fired power station has been operating in Devon since 2002. See post 57141
