How should you drive a sports car?

Surely a hydrogen car makes more sense.

The waste is H2O.

The fuel is H2O that needs electricity to split it. The fuel can be slowly formed using solar (PV) cells on the roof of your house. Off peak electricity (cheap tarrif) can be used to overnight too.

It makes a rubbish fuel though. It either needs to be compressed, which means a small heavy tank in the boot that might go boom, or frozen to near absolute zero, which isn't great either.

There are industrial charges with high amps that can recharge those cars very quickly - 15-30 mins, it's not something you can find in average household though.

Give it 5-10 years and finally nanotubes will be good enough to create instantly chargeable batteries - after that sky is the limit.

I bet that heats up the battery bank a bit. That's a lot of amps.

Or there is wireless energy transfer, Tesla (not the car) came up with this first as it happens, or electrified roads.

I'd go with compressing it.

Not sure how safe a tonne of laptop batteries with a short circuit are either.

Why not cut out the hydrogen and keep the compression bit? Compressed air energy storage is supposed to be as energy dense as lead-acid batteries and takes up less space than lithium-ion batteries, so it won't get you far. Refueling is quick though.

Or just make simple hydrocarbon liquid fuel, which I think can be done now without the aid of life.

Anyway, back to the topic - driving any car aggressively would use up more fuel as all fuel tests are designed for "normal" driving with particular emphasis on driving in a way that increases MPG in the test.

Can we have some proper SKA news please.

Not how many GB of ram you have, but how close to being the first birmingham bedsit dwelling immigrant millionaire you are.

Hydrogen is a viable option although you don't generate the fuel quite as simply as that... however it appears fuel cells might still bypass that technology.

Another here, that doesn't require you to cover your house in solar panels.

How about a nuclear powered hydrogen car? Spent fuel rods aren't in short supply (even described as 'waste') and will happily generate hydrogen if mishandled. It could blow your roof off though. Either that or buy the hydrogen off the Japenese who aren't in short supply of H, but then you've still got the storage problem.

Nuclear plants may be clean hydrogen source

Fancy a nuclear powered car?
