I guess you never been in a data center in the last 10 years. All modern DCs run on DC power because stepping down voltage is easy and 95%+ efficient. Why do we backhaul electricity across the country by DC and convert into AC to our house and then back into DC for our stuff? Add renewable energy generation like solar cells and battery storage and AC makes no sense.

Theres a reason why china is spinning up DC power grids while posts like mine get bashed on.
