you know like a washer and dryer?
and it would be a very small load of white clothes?

A: It all depends on how fast the washer fills with water, the temperature setting of the water, the water level setting and how long the wash cycle is set for. Roughly you can figure on 20-30 minutes.

UNH seniors create bicycle-powered washing machine

DURHAM — A senior capstone project by three University of New Hampshire mechanical engineering students could make life easier — and cleaner — in developing nations. The project, a bicycle-powered washing machine, harnesses plentiful bicycles and salvaged materials to clean clothing with just six gallons of water, 30 minutes of easy pedaling, and no electricity.

"In countries where washing machines aren't available, this would free you up to do more interesting things," says Britta Moore '12, who designed and created the washing machine as a senior capstone project with Garrett Cassidy '12 and Vincent Lyon '12. The trio was inspired by a TED Talk speaker who addressed the life-changing impact of washing machines in rural areas.

"The purpose of this product is to bridge the gap between convenience and sustainability," the students write in their research poster. If the students are successful, their invention could bring a whole new meaning the concept
