Sure you can have these fancy concentrators, but nothing will cost less per kW than plain solar panels arrays or wind power. Why concentrate the suns rays instead of using solar panels, whose costs decrease all the time?
Concentrated solar power is a popular concept because mirrors cost a helluva lot less than solar panels.
Actually, my money is on plants, because they cost a helluva lot less than solar panels or mirrors. Yeah they're probably around 1% efficient compared to 16%-18% for most commercial panels. But who cares when plants are biological solar collectors which build themselves. No human intervention or energy cost needed (though it can help speed up the process). We just need to figure out a cost-effective method of converting cellulose into a more utilitarian fuel and we're set.
