Neat. We need more "box of hot rocks" thermal storage solutions.

It's fun to compare and contrast strategies, as startups explore and define the problem space.

For example:

Fourth Power is a heat to electricity solution. It uses graphite bricks (up to 2400°C), liquid metal for plumbing, and thermophotovoltaic cells.

Electrified Thermal Solutions is an electricity to heat solution. It combines the heating element, storage, and exchanger into a single brick (up to 1800°C).

antora also is a promising thermal pv company - heat up some carbon blocks resistively when clean power supply exceeds demand, then convert back to elec during peak demand or outages via pv panels operating on IR. Hopping container form factor. interesting partnerships w NREL and other gov partners.
