This sounds promising. I’m puzzled by what is used for the photovoltaics and how it can handle such high temperatures – 1000 deg C. The glowing ferrosilicon generates a lot of infrared so in order to have 40% efficiency the photovoltaics must convert a lot of the IR to electricity. https://www.pv-magazine.com/2022/03/23/latent-heat-thermophotovoltaic-battery-for-renewables-storage/ I know a bit
