Nobody knows, we’ll find out. But here is a hypothetical:
-If you start with a charged battery..there is your initial power source. -Dual battery system -Primary battery powers car AND secondary energy source. (Whatever it may be) -Secondary energy source slowly charges secondary battery. -When primary battery is depleted, the entire mechanism reverses. -Secondary battery becomes primary battery -Former primary battery is now being charged while former secondary runs operations
I already said to go look it up if your interested. Not hard. That's what I did 8 (yes 8) years ago when my friend told me about this. I'm sure it has advanced to the point it could be used in 2021. Plus, I didn't invent the nano-technology usage in generators, just a big FYI for everyone that re-chargeable car batteries are a reality and not some made up sci-fi Star Wars thing.
