  • All this worry about charging is not really the problem in my view. The whole idea of electric vehicles sounds good to those who think any combustion is bad, but is simply impractical and ridiculously expensive unless the whole basis of our economy becomes stone age. Examine the HGV problem above, in terms of supply. 250,000 Trucks at an average consumption of 100kW each. Supply required 25GW. So we need to increase the entire electrical infrastructure by 50% or so, and then there are cars and vans, perhaps another 25GW (25million units x 1kW average each), taking us to doubling everything. What have we achieved? We have moved the burning from the vehicle to the power station at immense cost! You say nuclear, wind or solar sources but how do we do that, these are already a serious problem in many ways at perhaps 15% average supply? It may be that gas is fairly "clean", but so was a coal station with flue treatment! It may be that gas is a bit more efficient but not spectacularly so. New build of 25 new nuclear plants of 2GW each is pretty much impossible in any reasonable timescale, doubling the grid the same, and the local distribution enormously expensive. It cannot be afforded without a tax on electric vehicles of perhaps 200%, and at that point the economics become clear to the proponents of this impossible scheme.


    So the conclusion must be that the aspiration to electrify transport is impossible without a huge reduction in transport overall. It seems that electricity is thought to be "free" because it cannot be seen and is nearly non-polluting at point of use, but the whole system is not and cannot be. Society as we know it without virtually unlimited transport is basically pre-industrial revolution, and cannot support anything like our current population.


    The problem is not the connector or cable at the charging point, it is the overall system design, which is fatally flawed although it seems that no one else has realised this! The fundamental misunderstanding behind the whole concept of electric transport is that CO2 is harmful to life. It is not, cannot be and in fact is the opposite! Do all these batteries, wind generators, solar panels, power stations etc. have no CO2 footprint? Of course not, it is just as big as the present system!
