Sharing Knowledge To Make A Better World...

"We send our children into the world with the notion that a house must have a pitched roof, a square window and a chimney. How can they ever imagine they can build something beautiful out of dirt?"

Eco-engineers Dick Strawbridge and Jem Stansfield are down on the farm in rural England and must tame a fuel-guzzling monster by turning cow manure into natural gas.


Farmer Andy's grain dryer uses 90 litres of gas an hour to dry 10 tonnes of grain.

Drinking over 450 kilograms of fuel for one crop, this gas guzzler burns as much fossil fuel in one ten hour day as a family car might in an entire year.

Cashing in on the farm's hefty amount of cow dung, Dick and Jem hatch a plan to harvest the methane found naturally in cow manure.

But storing a vast amount of this explosive gas is dangerous and Dick and Jem must work out a solution to keep their latest eco-friendly experiment from blowing up -- literally.

The pair cuts down an old 2-ton oil tank and submerge it in a custom-built massive water bath to minimize the explosion risk.
