We need 10 years of study and another 20 of experience to have 1 guy capable of doing the brain surgery. You need a lot equipment and rules and liability, infrastructure and all that to do it. It’s extremely expensive.

But mints are everywhere and anybody can do it. :) Effective? probably not.

But, to keep in line with the phone example, you can have a battery load in 10 minutes, and still have reasonable cycles, fine, but it’s going to cost or going to be bigger, unless we find a new material that changes the paradigm.

As this is using just same old lithium.
