Fortunately I have someone (a very close friend) doing first line research in soalr cells for the  last ten years.. she is a great researcher coming from the great unviersity suystem of spain (Barceloan too) .. in phsyics.. and of course after spending a lot of money in her education the spanish state is using her by.. well... suffice to say she is now working in research for an europeaa company..at least european.. but of course.. not in Spain..

She has told me a lot of times that efficiency is not really a problem... silice cost is the problem.. the same efficiency but with any kind of cheaper material and the future is all solar.. the problem is that this new material is not there yet..

So they are coming with cheaper ways to process it..soa s to spend less enrgy int he proces of creating it (first roadblock) and with ways to put less silice without losing the 10% efficieny  (that's all it is needed she says.. 10%.. more than enough.. acutally 5% would be fine with most of the elements you can find in the market...)

So... what to do... research on new materials.. and ways to recude the silice requirements of the cell.

On the good side.. she also projects huge growth in the sector because there have been very important discoveries in the last ten-fifteen years... and now these technologies will move mainstream and reduce the price heavily.. especially on the energy requirements of the production (deposition).

That was for the last part of this great diary.. regarding the comparison with wind.. I just sit and listen to the experts discuss (jerome, you.. and the rest....) I just learn.

A pleasure
