Osaka, Japan, initiates several projects to revitalize rivers and waterfronts. One of the projects of the event 'Aqua metropolis Osaka' will be a giant floating water cleaner running on solar power.
"The disc-shaped machines -- called "Solar UFOs" -- weigh about 3.4 tons each and measure 1.6 meters (5 ft) tall and 5 meters (16 ft) across. During the day, an array of solar panels power the machine's filtration system, which pumps fresh oxygen into the water while removing impurities. At night, a 1.3-kilowatt solar battery provides juice to the LED lamps lining the edges of the floating craft.The machines, which can purify about 9,000 liters (2,400 gallons) of water per day, spray the clean water out through a nozzle on top, like a fountain. In addition to keeping the surface clean of bird droppings and grime, the water spray keeps the solar panels cool, helping to maintain a high output efficiency. Plans are to keep one Solar UFO operating in the Dotonbori canal (in central Osaka) until mid-October. The one in Osaka Castle moat is scheduled to remain in operation until the end of March 2010."
I would like that in Amsterdam!
