I doubt we're going to see any kind of combustion engine which produces no CO2 unless it runs on pure hydrogen mixed with air - the air thus providing the oxygen necessary for combustion.
We're not ready politically, nor socially, for fully electric cars. Nor is the technology sufficient to provide usable range and performance.
Anyway, if these [electric cars] becamse readily available and cheap what would we do with all the cars we have at the moment? Landfill? That's gonna be really good for the environment, isn't it? This is something that the tree huggers forget.
I don't have a problem with electric cars per se, but if we're going to do it properly then we have to adopt nuclear energy for electricity generation. Nothing else is remotely efficient enough. I am in favour of nuclear generation - it's clean and quiet.
Electric cars are quiet, too. Something I like. Some argue about pedestrian safety because they'd not hear the things approaching, but if every car was electrically propelled then there'd be no petrol and diesel engines to mask the small amount of noise an electric car makes. Whole towns would become quieter places in general.
There's another benfit, too. If electric cars become commonplace then the remaining fossil fuels will last longer so we can carry on driving our liquid fuelled cars for longer if that's what we choose to do.
