A concrete thermal battery could be key to cooling data centers at scale — 150Kw prototype that can withstand up to 500 degrees centigrade is running

Thermal storage moving into concrete form factors is a direct response to AI data center heat and power constraints. If 150 kWh units pencil out, expect site selection and cooling design to shift toward co-optimizing land, materials, and waste heat reuse, not just cheap electrons.
