FFS dude If you're going to cite sources like that at least get it remotely close to right. "For aircraft, or just generally, you want to move a large mass of air slowly. So you can reduce the velocity component of kinetic energy, which goes as the square. You want to move a large amount of mass slowly, not a small amount of mass fast... So, the way you make aircraft engines more efficient is you move a lot of air slowly. Like big fans, basically, big slow fans work great. Small, tiny. fast-moving jets, are very inefficient." - your favorite billionaire, in the exact interview you're inversely misquoting. (JRE #1609 last ~12 minutes is electric planes) |
