That is one pretty car! But pretty doesn’t get you there any sooner.

The problem is that the electric utility and firm providing the charging service would not be able to handle the 1 minute charge time, without incredible infa-structure investment.

Under that National Electric Code all components must be sized to handle at least 125% of the maximum current. This requirement often results in most conductors, transformers, etc. being twice as “big” as required for residential and commercial electric installations.

Most electric utilities (which are designed to the National Electric Safety Code) don't have to generally follow. Instead they use assumptions on diversity of loads. Charging stations are very problematic for electric utilities as most of the diversity studies don't cover such loads.

Nothing is 100% efficient. Enough waste heat to cook an elephant?
