“This mirror is 100 times cheaper than mirrors for cheap solar electricity & thermal energy
This concave mirror is made from expanded polystyrene and this reflective film at a cost of 25 cents per square meter, and it is several hundred times cheaper than these mirrors which focus solar radiation to convert it into heat and electricity, and such a radical reduction in the cost of similar mirrors makes their electricity cheaper than from solar panels, or thermal and nuclear power plants.”
