I think that show was from 2004 or so... Plus it is created in the UK.
BUt, your right. Isn't that one of the "laws" of physics.
"There's no such thing as a free lunch."
The could add a compressor to the drive shaft, but it would add extra drag to the engine so it would have to work harder... I bet if you calculate it then it would be a net loss. But, I could see them doing something like hybrid's do today with regenerative braking. Use that inertia to run some compressors to replace some of the air during breaking.
I also would want to get a higher speed compressor for my house rather than waiting 4 hours for the thing to fill. But, I guess is it really gets an 850 mile range per "fill" then it should be ok. Or course, I assume the mean full air pressure and petrol.

PS: I don't see how it will be "zero" polution either. I guess unless the fuel they talk about using to warm the air is clean burining like natural gas or propane or something... but doesn't combusion give of CO2 by definition?
