Toyota thinks it has cracked the problem of refuelling electric cars without
building charging stations all over the place (EP 957 063). If cars use hydrogen
fuel cells to generate electricity, existing petrol stations can be adapted to
generate hydrogen on site from the natural gas supply (¿ìè¶ÌÊÓƵ,
18 March, p 20). The hydrogen will be pumped into a vehicle’s tank via a pipe
with an electronic monitor that tells you how much gas is needed, so you don’t
overfill the tank with highly explosive hydrogen.
