you ought to get a response.
ive become a bit skeptical of renewable energy schemes,
as its argued some dont recover the energy it takes to build them, but this might be promising, its a bit like the film sahara where they had a field of mirrors pointing at a tower wich melted stuff. suposedly photovoltaic cells made from silicon wafers arnt likely to generate the energy used to make them, good only if you not near a local electric system.
amorphous silicon is less efficient but takes far less energy to produce, the thing to watch out for is plastic solar cells ! theyr actualy called polymer semiconductor. they not very efficient but they recoup the energy needed to make them very quickly.
the distribution system is also a quite an investment, my idea would be to put all the industries wich need a lot of heat eg, smelting and foundries etc as part of a CSP system.
