Sulphurreal's solar sulphur cycle makes unlimited thermal energy storage

https://www.solarpaces.org/why-solar-sulphur-cycle-ideal-seasonal-thermal-energy-storage/

"sulfur’s energy density order magnitude higher/ sand particles remain stable without degrading at much higher temperatures than molten salt... sulphur is cheap... burning using concentrated solar (no C02 emmissions) enables 1000° - 1500°C, centrifugal force creates dense particle film absorbing heat... enclosed endless cycles: sulohur --> sulphuric acid (valuable in itself)--> sulphur dioxide --> sulphur... power density >5 MW/m³ at ambient pressure (> 75 MW/m³ at 15 bar pressure)... seasonal storage"
