Reply to comment by polar_pilot in Seattle-based Jetoptera is developing a vertical takeoff aircraft that can travel at almost 1,000 km/h with a radically simplified new type of engine. With almost no moving parts, it uses super-compressed air to create vortexes for thrust. by lughnasadh
Traditional planes can glide some and hit the ground at a more gentle angle and do I recall that helicopters do some slow rotator spin to make landings more survivable?
That was something that came to mind, if these are an improvement on helicopters that'd be great, but if they became known as deathtraps when the engine fails it could tank the tech forthwith.

Most things can glide given the right conditions. 😁
More seriously, I'm no aviation guy but gliders tend to have longer wings and are light particularly because of their lack of engines. So while traditional planes can glide some, the compactness of this design makes me think it would be especially poor at gliding.

Reply to comment by Shape__Shifter in ELI5 why do electric vehicles have one big battery that's hard to replace once it's expired, rather than lots of smaller ones that could be swapped out based on need (to trade off range/power/weight)? by ginonofalg
The big batteries are already made up of smaller batteries internally.

Funny they went to the trouble of fitting into the lore but still made him half human.

> generally useless
Firefox now has JavaScript JIT acceleration for their RISC-V builds. Most of what I do is in the browser (and all of it could be in the browser) so doesn't seem generally useless to me.
