Wow, a mere 150 seconds to recharge and 20 year lifespan. With a few
good solar panels and wind generators, who would need the utility companies?
It would be nice if they could effectively replace the batteries in
electic cars. Unfortunately, the additional weight may short-circuit
any gain.
If you read some more of the fine print, the unit that charges in 150
seconds will supply its rated output for 120 seconds. No free lunch.
But plenty of time to get the diesel backup generator fired up.
Also, these are rather large, in the hundreds of kilowatt range. Not
the thing for the average home computer.
