no dude, it's well worth looking at, for your house, or for a company,
or for many things, however, for an overall energy solution and
looking at the world grids, it needs to be able to provide a
measurable fraction like say 10% fully deployed to be worth
considering. Granted that this is a technology worth exploring
wherever it is viable, but it's unlikely to make a splash.
