David has a chain reaction
A PEDAL power scheme which could be the answer to irrigation problems in developing countries has been devised by Northumbria University student David Brightman.
David’s design for a bicycle-powered water pump is part of the Graduate Show at the university.
He has designed a system where a bike is attached to a pump which is powered by pedaling.
David, 22, said: “This would be ideal for small scale farms which are lacking in reliable equipment, and can be used to irrigate large areas.
“It is low maintenance, low cost and doesn’t need any extensive machinery. I was also aware of the large number of bikes which are sent to landfill in this country.
“My idea is a very practical mode of transport, which can help make a real difference to the lives of people in the developing world.”
