Cars run on explosions
electric cars do not run on explosions
Electric cars run on outsourceed explosions.
Depends where their electricity comes from :trollface:
Eh most energy on earth can find it's source from a star or supernova, so close enough for me. Even ice cars are solar powered.
I mean if you want to get right down to it, literally everything that does work is solar-powered.
The universe's explosions!
While they can it's unlikely, not all burning of stuff is an explosion, and not all electricity is made with burning stuff.
If you are charging up your Tesla with a generator, maybe, but where fossil fuels are burned in powerplants it's incredibly unlikely that it's an explosion in an internal combustion engine. Generally it's a big fire that heats water to steam.
this is not true. They run on controlled burns. When explosions happen that's the engine knocking, which is a bad thing
It's a fast controlled burn with forces that could cause much destruction but is instead directed into rotational movement. The difference between an engine knocking and not knocking is pretty small, so I'd argue either both cases are explosions or neither are. Explosion isn't a very scientific word anyway
it's a fast controlled burn propagating subsonically. Which is what makes it a burn instead of a detonation.
Not that I trust Google, but I did a search and the first result said "A detonation is an explosion where the flame speed is greater than the speed of sound."
That implies there can also be explosions that are subsonic
I also found this wiki page https://en.m.wikipedia.org/wiki/Explosion Deflagration is listed as just that. And cars run on Deflagration, so therefore they run on explosions
This is not true. Knocking is just when the explosions happen at the wrong time.
