I'm liking the general idea; I have doubts as to whether it will significantly reduce overall costs - certainly a bit, but the majority of the cost of the cells is in deployment and general maintenance before payback, and as far as I can see this process, clever and admirable though it is, will probably only make a small dent. That's a bit of a lame gripe by me though - there is clearly a massive amount of development that we could push with solar that will push the per-unit cost down further, so, like the cyclists say, stacking a 1% advantage here on another 1% there and so on - it all adds up!
