Can you beat this from Walkers Crisps (Chips) in the UK:
Potatoes are 80% water, most of which is lost as steam when 350,000 tons of spuds are sliced and fried annually at the factory. Seal hopes to condense the steam, possibly with a system of cooling tubes, and reuse the captured H2O to clean equipment, help wash potatoes along manufacturing lines, and even irrigate the shrubs outside. The method could save the plant $1 million a year. "Lots of people think we're nuts," says Seal. "We're trying to push the boundaries to make a difference."
