Bicycle Purifies Water Through Manpower

A Japanese company has produced a bicycle that can also be used to purify water at disaster zones or remote villages.

"If you can bike to a river, pond, pool or other sources of water, all you need is your leg power to produce clean drinking water," Yuichi Katsuura, president of Nippon Basic Co. said on Thursday as he introduced the system.

Cycloclean needs manpower to turn a bike chain driving motor to pump water through a series of filters, unlike other systems requiring gasoline or electricity. 

The bike features puncture-free tires, while the pump and hoses are housed in an attached box on the rear carrier and three filter cartridges are fitted around the rear wheel.

Katsuura said Nippon Basic has sold 200 bikes since first launching Cycloclean in Jana in 2005 at $6,600 each.

He said many of the bikes went to Japanese local governments but a small number were sold to Bangladesh, Cambodia, China, Indonesia, Myanmar and the Philippines.

Katsuura said the company had seen demand rise in Bangladesh and started local assembly late last year, partly to help reduce the price in cooperation with a Bangladeshi bicycle maker.

"We hope local production will go into full swing around April," he said during the presentation, adding his firm and local partners were aiming for annual production of 100-200 units.

He argued that Bangladesh's millions of rickshaws would decrease as its economy grows, but a bike-water business could provide new jobs to some of the drivers.

"You go to where water is, put your bicycle on a stand, drop a pump and peddle for clean water, which can then be sold elsewhere," he said.

He also said that the pump was capable of sucking up water at a depth of 16-feet despite its "low-tech appearance."

Cycloclean was on display at an environment-friendly technology fair in Kawasaki, which ends Thursday.
