Solar powered water canal cleaners in Osaka
The engineering firm NTT Facilities has developed a pair of solar powered floating water purifiers in the shape of a UFO; I am guessing the designer sees a lot of alien movies, as a part of the upcoming Aqua Metropolis festival in Osaka. This will deployed in the city’s canals and in the moat at Osaka Castle. The Solar UFOs as they are called weigh about 3.4 tons and measure 5 feet tall and 16 feet across. An array of solar panels will power the machine’s filtration systems which will pump fresh oxygen into the water removing impurities. It is also fitted with a 1.3 kilowatt solar battery which provides the power for the LED lights lining the edges of the floating craft during night time.
The machines are capable of purifying around 9000 liters of water per day, spraying the clean water out from a nozzle on the top like a fountain. Unfortunately these water cleaners are currently not up for sale, but I feel these will make a good business opportunity if commercialized!
