That's awesome but assuming that that means getting Tesla Megapacks at half the price (inverters and infrastructure would likely prevent a 60% reduction and it makes the math easier), you're now getting 16 hours at 300MW out of your batteries for the same price as a 300MW nuclear plant that runs 18-24 months before refuelling.
