Battery Powered Commercial Airliners Coming

What Commercial Aircraft Will Look Like In 2050 | IFLScience

"Tesla CEO Elon Musk has said that once batteries are capable of producing 400 Watt-hours per kilogram...

....Given that practical lithium-ion batteries were capable of achieving energy-densities of 113Wh/kg in 1994, 202Wh/kg in 2004, and are now capable of approximately 300Wh/kg, it’s reasonable to assume that they will hit 400Wh/kg in the coming decade."

But don't charge your cellphone in flight, if you know what's good for you.

I've been on this planet long enough to have seen predictions of:

• The 20-hour workweek being common, with the biggest social problem being how to spend all that free time.
• Jet-packs being the new personal transport
• Jetson-style bubble-top flying cars... and everyone's got one!
• Robots doing all our housework (dishwashing machines and clothes washing machines had already been around for ages, so I'm not talking like those are sort of robots)
• CBs (Citizens' Band two-way radios) will be standard in all cars... along with a whip antenna.
• We'll have Mars colonies by 2000
• We'll have electric planes in the near future (prediction from 1970s)

Paint me skeptical about commercial electric planes. As for Mr. Elon Musk and his predictions, I'm skeptical there, too. He has a hard time accurately forecasting his own company's sales numbers each quarter (less-popularly called "always missing his own self-imposed sales targets"), so I don't put much stock in his predictions about commercial aviation.

Only 33 years when I turn 100. Won't be flying on any planes then. Y'all can have the battery fire in a commercial airliner, jumping out without a parachute LOL.
Look for a haystack like a few WW2 airmen did when they could not get to their chutes in time.
