The amazing thing is there basically were no batteries three four years ago. And they can supply about 10% of the max power demand already. So it feels like the technologies we need are now good to go on an engineering an accounting basis. And adoption can be quite rapid. We're not saying in 50 years, 25 years, 10 years. We're looking at 5 years.
I've looked and not seen numbers on the actual battery capacity. But I think it's about 3-4 hours at name plate power levels. I think from what I know capacity is a function of discharge rate. And wear is also a function of discharge rate and max/min charge levels.
