For people like me though were the commute is say 10miles each way at 40mph stopping for various lights/junctions and i then work mosty a 12hr shift, sometimes 7hr i can get to work, plug in and start my shift and know i will have enough juice to get home. Then on longer journeys just use the built in genset to keep the thing going. Yes they can ber very bad for the enviroment depending on how they are produced but i firmly believe if we do not start to quickly get growing BioD in very large quantities ASAP we are going to be stuffed. Large ships and such forth could use it quite easily instead of normal diesel or heavy oil and cars don't take much if anything to convert to get them happy on it. IIRC at the minute 5% of all pump diesel is BioD anyway so upping that to say 20% would easily help bring down the cost and help relieve the strain on diesel supplies.
If they move these ERV's to diesel units instead of petrol like most have then it will help but they stick with petrol as it is much smoother when kicking in and out
I've even considered a bloomin electric scooter
For EV's to really take over the only way is to start covering parking spots with inductive loop charging systems and fit them to the cars, ie have them at traffic lights and on slips roads. lights because you can often spend a few minutes there and slips roads as an extra way to decrease drain during an acceleration cycle.
If solar cells get better like the tech news i've been reading suggests then having a roof covered in them wont be too far off and will enable some juice to flow back into the car
On board power generation is one of the best ways to move forward, loco's have done it for years now and some even use Gas Turbine engines are in some
I see Electric as being the next small step in the chain as the torque from motors is only getting better and thats what matters as most of a cars energy is used getting it upto speed and then very little for cruising (unless its a big old tank

) which is where they excel as peak torque comes in a 1rpm nearly all the way upto their rev limit and anywhere inbetween can have a tiny bit of power to just keep them ticking.
Then when you need to brake they recoup that energy instead of throwing it all away as heat and metal dust

and there will always be a loss in transmission thru the circuits and so on.
I just think its a little like ARCS, When citroen demo'd it and people laughed and said it would be too expensive to put in road cars and it would offer no real benefit they proved them wrong and im sure along the line it has saved plenty of lives through greater control in extreme conditions.
They were the first mass production company outside of the states, the first all steel car, the first mass produced front wheel drive and at the same time the first monocoque.....
Its just another step and while as a step its flawed and has its problems it will lead to something better and if it helps reduce our dependence on oil its all the better i say.
For the issues of growing BioD and Ethanol many plants are now being found to grow very fast and help create a decent amount of oil for the amount of energy put in, its just landspace... Which makes me think we have big deserts around the globe that are just unused and should be used.
Even things like Hempcrete interest me as it insulates and while not as perfect as normal concrete at least is more carbon nuetral which is the big thing at the minute and if you can regrow something surely its good
