A long range motorcycle, powered by nothing but air...

Why bother dealing with gas, or even electricity? This bike zooms along at over 80 miles an hour using nothing but a scuba tank.
 

Electric motorbikes are slowly gaining acceptance, even among some diehard gear-heads. But electricity isn’t the only means of powering alternative two-wheelers; good old, plain air is also a viable, and sustainable, possibility.

Propelled by compressed air, the O2 Pursuit can go 100 kilometers on a single tank, and up to 140 kilometers per hour (87 mph), according to Dean Benstead, the graduate of RMIT University, in Melbourne, who designed it.
