A full tank is safer than an almost empty tank.. Also the tank is designed to keep the vapor part of the gasoline too saturated to explode, this is why there is a latch on the fill tube. I found this Quora post: https://www.quora.com/How-come-the-gasoline-in-gas-tanks-never-explodes-What-makes-a-spark-so-impossible https://www.quora.com/How-come-the-gasoline-in-gas-tanks-nev... And even if it can explode in the situation where there's almost no fuel left, in that case it's not as bad as liberating the full energy of a full tank, which is what you'd do if you have a flywheel spinning with the same total energy as a full tank of gasoline. That would be madness. Heh I came to think of the recent demo of the company that wants to spin up satellites on earth and THROW them into orbit. If something goes wrong in that spin-up, they would destroy the entire launch facility and whatever is in the way. https://youtu.be/JAczd3mt3X0 https://youtu.be/JAczd3mt3X0 I once had a CDROM open while the CD was spinning at like 40x or so, it ejected and went into the plaster wall. And that was just a CD..
