The BIGGEST problem with clean energy

I don't think it's surprising that the most inventive alternative power solutions seem to be started in California. It has the right climate and wealth to facilitate this. I can remember way back in the mid eighties spending time in San Francisco and Los Angeles and being surprised by the amount of wind turbines when there was hardly any in Europe. As a history buff I knew about how important windmills and waterwheels were as a technology way before the industrial revolution and although we had a lot of hydro electric plants in the UK especially in Scotland we didn't look to the future then. In fact it was all about North sea gas at the time. I guess solar energy is more predominant in States like California and the development of companies like Tesla and Zero motorcycles is not really a surprise but it is difficult to replicate such things here in the UK where the oil industry has such a hold on politics and technology and of course we don't see so much sun. Of course we do have a lot of wind farms now and I'm sure the oil companies can see the end of their days with our governments setting a target for no new ice powered vehicles produced in the near future. I have mainly been looking at different technologies for battery production and it is interesting seeing the research and development of the mechanical storage solutions you are doing over there. Maybe we could save the planet after all?
