Making an airplane drone fly with solar-powered batteries is conceivable. The drone, usually a glider, just requires an extra piece of energy to take off and once in a while during its flight.
But making an aircraft ― a human pilot inside ― fly with simple batteries is… Wow, speechless.
And according to AFP, Japanese Matsushita has made it. Their glider-like plane in picture took off the ground for a 391-meter long and 5-meter high demonstration flight. Its pilot weights 53 kilograms.
But we’re not making an apology of electrical batteries ― especially the batteries used in the project, which are cousin of alkaline batteries and produce 1.5 times more power. We’re not saying that. But it’s a first step on the road to all-solar powered planes.
