r/worldnews - Bill Gates backs startup using sunlight to create 1,000C-plus heat - The world’s richest man is joining investors behind Heliogen, the first company to concentrate sunlight to reach temperatures that are high enough to power heavy industry without carbon emissions.

Concentrated solar power has been around since the 70s and various plants exceeded 1000°C by far. Silly headline. What happens when there isn't sunlight. Meanwhile production isn't even reliable. How much more has it cost just to make a furnace? As those parts stress and break far more.
