That is a compound system that uses extra solar fields to charge eutectic salts to provide for full capacity night time output and non period output. The general solar field figure is 50 megawatts per square kilometre. Your calculation there came to 36, so there is a discrepency to find a reason for. We are designing a PV system (I think that I have already noted this in your area) that will put 10Kw capacity on house and small business premesis rooves. This system will deliver 19,200 Kwhrs per year (+other energy) in Sydney. This is a very different construction to normal PV and does not disfigure the appearence of buildings. Where such a system is suitable it will provide all of the electricity for a family of 4 plus the energy required to run 1 car (the above VW) with a charge every day and a half (186 miles range times 3 per week). Once the units are paid for the energy thereafter is free. The point of the comment is that there are solid energy systems on the way using todays technology. I do not see the people to need to significantly reducing their life style unless they are massive energy wasters. Replacing gasoline with electricity with solar will be no big deal, and could well happen for many sooner than previously thought. Improvements in electric vehicles from VW

Or did you realise that internal combustion engines (working fleet) are 35% energy conversion efficient whereas electric vehicles (properly designed) are 90%+ (running) efficient. ie require a third of the energy charge to power them the same distance on electricity alone.
