Hydrogen Car

Several newspapers covered the launch of another hydrogen fuel cell car. This Riversimple Urban Car ticks several boxes, being made of carbon fibre and powered by fuel cell and electric motors. Also it is "open source" that is, designed collaboratively.

The car will be available for leasing rather than selling, which is a step forward as the split incentive is removed - both lessor and lessee will want the car to be economical over its whole life and not just to have a low first cost - but a fixed monthly fee will make people drive it more to get their money's worth. A pay as you drive cost model would be better and the next logical step would be to have the vehicles available for hire, of course, so that they're not sitting around doing nothing most of the time like most privately owned cars.

If the government really wanted to do something about pollution from motor vehicles it would be finding ways of getting refuelling stations out there to support hydrogen vehicles.
