Another classic “Solution in search of a problem…”
EVs were going to be Jetson-like “intercity commuters”–but lacked the range, payload, and places to land. Then the prediction was for swarms of drones–either carrying passengers, or “something important.” Hasn’t happened…and has been pointed out a number of times–perhaps best by Chris C, William, and Jeremy H.
It has also been pointed out that the vehicle (the R-22) has existed for years–yet nobody has seen the need of the service.
If anyone REALLY BELIEVES this will be a “thing”–they should mortgage the farm and invest in the future–if you are right and the physicists are wrong, you can make a killing! That’s the benefit of the Capitalist system.
