The New York City transit agency began a two-month trial of a 35-foot-long electric hybrid turbine diesel bus yesterday.
Unlike New York City's other hybrid buses that run on electric part of the time and regenerate by brakes (like gasoline car hybrid systems on the road), this bus runs on electric power all the time. A diesel turbine engine recharges the battery when needed and power is recovered by regenerative breaking.
The bus made by DesignLine International Holdings LLC. gets 7 miles per gallon, double the city's other hybrid buses.
Wow! If 7 miles/gallon is double the economy of a hybrid bus, I shudder to think what a non-hybrid bus gets.
On a somewhat unrelated note, check out the nifty wind belt...

It's so simple that I'm tempted to try to make one myself.
Drats! Must have goofed up the HTML for that link. Oh well, here's the actual address...
