Walking on Sunshine

A solar-powered plane has just completed a 26-hour flight, the nighttime portion of the flight being powered by the daytime portion – with power to spare.

With an average speed of 25 mph, solar-powered flight isn’t quite ready to render jet fuel obsolete; but it’s nice to see some progress on the power-sources-that-aren’t-depleted-by-use-and-don’t-cause-so-much-collateral-damage front.
