Assuming the theory (”double the voltage, halve the charge time!”) is viable (*cough*), consider:

- For me, “taking the kids to gramma’s” is a 1000-mile 16-hour trip. Save maybe one sit-down meal, food is drive-thru. Ain’t nothin’ like “recharging” every 400 miles in 5 minutes flat.
- Over 220v, electricity becomes an extreme safety issue. You don’t just double voltage in a family setting. Ditto for increasing current (an issue with fast-charging capacitors).
- Difference between gas & electric: with gas, you extract energy from a stable medium as-needed in small doses; with electric, you in essence convert all that energy all at once then try to contain it. It’s hard to release all the energy from gasoline at once; it’s easy to release all the energy from batteries/capacitors all at once ... the difference makes a huge safety problem.

So maybe Tesla needs to design a compartmentalized battery? Sorry if this is really silly, but:

If this is 110 volts,

why can’t you do this?

and get 440 volts?
