Remember those little CO2 cartridges that powered the acceleration of tiny balls of paint at your hoodlum friends?  Well…I do.  Now a similar principle is being used to power the acceleration of entire cars.  Or, in this case, entire rickshaws. 

Tuctuc limited has created several rickshaws powered by compressed nitrogen gas.  These vehicles will run a regular route around Brighton, England and will refuel at a proprietary fuel stop. 

Refueling is basically filling the tank with compressed gas which, upon expansion, powers the car.  Of course, electricity is used to compress the nitrogen, but, overall, it’s a much more efficient and less polluting use of energy than a gasoline engine.
