"...costs will need to be about $50 per kWh..."

Assuming such systems could be used at least 1000 times, you'd think that $0.05 per kilowatt-hour (each use) would be about an order of magnitude more generous than required.

If 10,000 usages lifetime, even more so...

So his numbers don't seem reasonable.
