yes, I know they are much stronger for the HP than IC technology, the original subaru hybrid conversion featured in MEN used a 10HP aircraft starter/generator, but they did add a cooling blower. We have a subaru we have converted to EV with junk yard electric forklift parts, motor is probably be around 15 HP, 36-48V DC, it runs, but we only had 4 regular car batteries on it and it pulled the voltage down hard just to start moving. So it's also waiting for my power supply. I also have a 25 hp AC motor, will put it in my 3/4 ton truck just as soon as I can power it suitably.
I was homeschooled and started at around 13 YO over 30 years ago visiting a big city library and reading the stories of inventors and their inventions, been at it ever since. I've come across some very strange inventions and talked to some modern inventors who were being shut down by big business. there's been a lot of stuff invented in the relm of energy that the general public has never heard of, stuff that would have wiped big oil out of existence many times over, which is why you never hear of it. I gotta be very careful what I say. stick with general terms, The world and it's governments are held under slavery by big business worse than hardly anyone realizes. While they maintain a fairly nice public image. It way too big for anyone to fight, all we can do is a few of us figure out stuff for ourselves and shut up about it so we don't get our heads chopped off. Mr T tried to give it to the world over 100 years ago but they stopped him then, and are still stopping it, so they can make big money on energy.
