This is just the beginning though. The real problem becomes one of energy density:mass. The developers already know that. That area is already showing marked improvement across the board. Right now it's just a startup. Imagine what will happen if an investor with real money decides to back it. How about a small ceramic gas turbine feeding power directly to the motors (and to a smaller battery pack for emergency backup power for a controlled landing in case of failure)? https://infogalactic.com/info/Gas_turbine#Microturbines https://www.sbir.gov/node/1654357 https://www.electrochem.org/dl/ma/201/pdfs/1108.pdf https://www.intechopen.com/chapters/45114 https://enertwin.com/ At one point I remember seeing an experiment using an alcohol fueled ceramic micro turbine only about 1 square inch and running at about 1,000,000 rpm. To be used to power electronic devices with better energy density than batteries. I retired out of a unit at Ft. Bragg in 2009. I can just about guarantee you that as soon as this video hit, somebody was up in the commander's office, asking him, "Why don't we have these?" When I saw the jet-pack guys doing a VBSS exercise, I thought, "Well, okay, that's very nice, but you can't shoot while you're flying that thing can you? It's loud af and you make a great target. This Jetson thing can hover. And be controlled by remote. Now imagine one or more guys with M240's being able to approach a target in these things and then hover just out of hearing range, in support by fire positions near the target. Imagine being a bad guy on the 20th floor of a building, thinking he's safe because of how high up he is, controlling the high ground, all of the elevators and stairwells. Imagine sending the Jetson out empty, by remote, in a remote SAR scenario with a thermal camera package. Find the subject, land next to them, tell them to get in, fly them out. Critical resupply with follow-on CASEVAC. Those are just a few, off the top of my head.

The first cars were a joke too
