Where the hell do they get the '5000 suns' part? That's completely pants-on-head stupid. We have only one star with enough relative luminosity to generate significant power. Hell - even the ONE PICTURE where we get stats, it rates the array at a concentration of 2.000 suns - that's exactly twice the normal light of the sun. I don't even know if we had the material and space to do a light concentration of 5000 suns - that's about 6805 kW per square meter. Really fucking hot. Hell - things would probably start getting impossibly hot just at 5 suns-luminosity. Overall, the technology in this article is nothing spectacular - it's pretty much, as far as I can gather, a really fancy solar array that can make hot water. I'm disappointed - I somewhat hoped for
