Water Purification on the Go

Water purification is as easy as riding a bike, according to Yuichi Katsuura, president of Nippon Basic Company.

The Japanese water purification company recently discussed ramping-up production of their portable system called "Cycloclean," which is powered by pedaling a bicycle. The man-powered system relies of the turning of the bike's chain to drive a motor to pump water through a series of filters. Nippon Basic estimates that the Cycloclean can purify 1.3 gallons (five litres) of water in a minute. Riding the bike for 10 hours would result in about three tons of water, an amount that could supply 1,500 people for a day.

The bikes also boast puncture-free tires and an "attaché case-like box" for housing the pump and hoses. Three filter cartridges are positioned around the rear wheel.

So far, the company has sold 200 bikes since the first introduction in 2005. Most of those bikes went to local governments in Japan and smaller numbers went to Bangladesh, Cambodia, China, Indonesia, Myanmar, and the Philippines.

Nippon Basic has already seen demand for more Cycloclean bikes in Bangladesh and hopes to bring local production into full-swing by April of this year.

General note: The WIRED link is pretty informative, with pic.

This is a pretty good idea. Too bad the going price (about $6,650 USD) is so steep. This seems to be the most value to people who do not have a lot of money.

As I consider, I am not too sure just where the $6,650 bucks is at. A bicycle, a water pump, couple of filters and fittings, some custom brackets and such... Maybe mass production will bring the numbers down.

1 purchase a decent rotary hand pump......$250.00

2. purchase a new mountain bike.....$800.00 (used maybe $50.00)

3. purchase the water filters as shown...$100.00

Bike to the river, there is a rotary handpump located there with attached filters.

4. Pump a gallon or two of river water, and put in about 20 ml of a tincture of iodine.

5. After about 30 minutes you have drinking water

6. Use the bike go to the market and get some fish and rice for supper.

I don't mean to crap on someone's idea but costing vs market suggests ..lets find an alternative.

How hard does one have to pedal the bike to generate what water pressure to produce said amount of purified water? Hardly any useful quantitative data have been given, but that's where all the action is....

Not all that new an idea- have a loook at Maya pedal, located in San Andrés Itzapa,
Chimaltenango, Guatemala. Although adding water filters to the system is not something covered in the Maya Pedal design.

I have a copy of a quick construction guide written by Jon Leary of Sheffield University for a bicycle powered pump (I believe I downloaded it from the Maya Pedal site, but I don't remember exactly). The document has a copyright notice, but includes an email address for Jon Leary, if anyone is interested. Looks like a whole lot cheaper than $6,000...
