Futurology

Spread it over enough people and it's the same energy. For one person it's a much shorter charge. Over a population with random charging times it's the same consumption off the grid. The problem then becomes a distribution issue, not a production issue.

Likely these kind of chargers will be expensive and at supercharge stations. Homes will use lower over longer.periods as it's rare you want to pop home for 10 minutes needing a full charge.

This is a big step forward, no matter how you look at it.

It might be also useful for excess storage when we have wind and solar energy that the grid doesnt need. Being able to do so rapidly will mean a smaller array of batteries required for grod storage.
