[Milsurplus] Brouhaha over Navy ROTHR radar

Large battery systems are interesting.  What kind of batteries are you 
using, how many and what voltage?  I see interesting problems with 
over-current and short-circuit protection.

I make large battery systems which solve the intermittency problem and yes those are now economically feasible as well.  My batteries are made in 1 MW chunks and run 4-10 hours depending on how much electrolyte is used. Typical real systems are 4 to 35 MW.  Investors buy the battery systems and sell the services to utilities and there is no subsidy from anyone. Ratepayers save money and both utilities and investors make their desired returns.
