The company produces its PowerSheet solar cells with printing-press-style machines that set down a layer of solar-absorbing nano-ink onto metal sheets as thin as aluminum foil, so the panels can be made for about a tenth of what current panels cost and at a rate of several hundred feet per minute.
Apparently the new Wembly stadium has more toilets than any building in the world. I bet the ladies’ room will still have a line, though.
