The trick is the use of computer vision (also known as a form of AI) to align a wide variety of mirrors when reflecting sunlight on a solitary target. This allows for the accuracy that has not been possible until now.
There is still a lot of work to be done before technology is put into use in the real world. Heliogen achieved the record heat level on the first day of plant operation, company founder Bill Gross told CNN . Although impressive, it will not immediately translate into a practical solution.
However, the implications are large. As Gates noted in the announcement, industrial processes are responsible for over 20 percent of emissions. If technology can cut even more of these emissions, it can help keep global warming at bay. Heliogen also has greater ambitions. It hopes to eventually reach temperatures of 2,732F, which will be warm enough to make hydrogen and synthetic gas. At that time you would have clean energy used to produce more clean energy ̵
