Yet another pretty picture with buzz word captions but no legitimate technology. The current high performance batteries are at (i.e Tesla) 244–296 watt-hours per kilogram (Wh/kg). Until we see a company brag about 400-450 Wh/kg batteries, we are not going to see anything but pretty proof of concepts.
So far, all these companies can do is get to the test flight stage with 20min flight time at max T/O weight. Then the company is unable to show a path forward for passengers and at least a 500mi range. The short range sweet spot is 100-250mi trips, where commuters are faster than ground or airline transportation. There seems to be no end to foolish investors.
