I hate nuclear with a passion but other 'alternatives' just will not provide the power demanded without expending all the resources we've got. Waste storage is always improving and storing radioactive waste in glass was quite a milestone as it means it will resist being leached into surrounding areas.
I agree the storage of waste is a problem, you just have to see the number of containers sat at sellafield to realise that. But we extract radioactive material from the ground in the first place, what is wrong with putting some back, albeit a lot more unstable than it was when we took it out.
I wish we could find an alternative, but so far all the 'alternative' sources have proved do little to provide mainstream energy, instead being used to up the supply when it drops below 50Hz as it's normally a lot quicker to set up than anything else, traditional coal and oil powerstations emit tonnes and tonnes of noxious gasses and pollute the ground around them, plus the transport costs of getting the fuel to them are stupidly high. We should keep a rolling program of nuclear stations online, they don't have to start popping up out of nowhere, they can quite happily be set up on existing sites.
But anyway, no the car is just another gimmick.
