Everyone knows about the pollution problems in China, especially people in Asia. The cities function in a perpetual haze with varying levels of visibility.
While walking down a street in Shanghai the other week I saw a gaggle of scooters coming my way. Not an uncommon appearance in Asian cities.
As they sped towards me I was expecting to be assaulted by the smell of gasoline and the high pitch hum of single stroke engines. To my surprise, they zinged by quietly. It turns out that most scooters in China cities are electric. They are cheap to power and cheap to buy ($100-300).
