Concentrated solar power (CSP) is used for energy production with mediocre (though improving) performance/price, and heats to like 500°C. As the article states their technology doubles the temperature and is cheap to deploy, applying AI in the process to do so.
Sounds like a huge step forward to me. And Bill Gates is usually on track with his investments in transformative tech..
Hydrosol-II is a thermo-chemical solar power generator (https://cordis.europa.eu/project/rcn/75098/factsheet/en). It uses solar energy in combination with recycled outputs from process to reach the desired temperature. It is not capable of reaching the desired temperatures (1000 C) purely through solar input.
Heliogen claims to reach the desired temperatures purely through solar.
