But how do you start the engine? DUN DUN DUN!

Because battries don't turn the crankshaft in cars, the engine does.

I meant to run the electronics, not the motor itself.

Are you being retarded on purpose? You better not be.

You can have a car's electronics on without the engine running. What you're suggesting is to do the opposite, which is both overkill and terribly inefficient compared to battery power.

Why'd you post a turbo?

Are you joking m8? What he described is literally how car electronics are powered

>>8991942
You do have a generator powering a battery up in most cars, but you need the initial kick from the battery to get the chemical reaction in the engine starting. It is like the bootstrap. Relying on battery to start the engine. Relying on engine and generator to refuel battery once engine has started.

Even better, you could build a device that spins faster than the engine, due to a pulley system with different sized pulleys. Since it's on pulleys you could mount it anywhere it will fit, but you'd probably want it close to the battery. Starters take from 100 amps to 300 amps to turn the engine over if it's not running, so you're not going to be able to get away from that unless you want to push start your manual transmission car every time you use it. If only there were a device that pulls electrons out of the positive terminal and jams them into the negative terminal though...

You can, it,s called a magneto, the main drawback is, without stored electrical power to turn the starting motor, the engine must be hand cranked, as in power tools, light aircraft, rc toys, t model fords, etc,
