Kawasaki from the air

T&A: Nikkei’s Tech-On published a feature story on Japan’s Kawasaki city and how, through anti-pollution technologies, the city has managed to see Mt. Fuji through clearer skies from a once heavily polluted, dark sky industrial city in the 1960s and 1970s.

In the city’s recently ended International ECO-Tech Fair 2009 (17-18 February 2009), several anti-pollution measures and technologies were unveiled, including a bicycle that uses pedalling energy and a filter to convert muddy water into drinkable water, and an electric car that can go up to 370km per hour (2015 is the targeted go-commercial year).

It is quite apparent that many Asian cities, including those HWM is based in, are now looking at how Kawasaki did it and taking lessons learned from the fair to bring home and study.

We’ve polled our various regional editors based in the various industrialized cities in this region to find out if there are any new recycling and anti-pollution technologies introduced that could help keep our skies cleaner. (Editor opinions: 3)
