The trick is to use Computer Vision (aka a form of AI) to align a large number of mirrors when reflecting sunlight at a single target. This allows an accuracy that was previously not possible.
There is still a lot to do before the technology is put into practice. Heliogen reached record levels on the first day of its plant operation, company founder Bill Gross told CNN . While impressive, it does not immediately lead to a practical solution.
The impact, however, is enormous. As Gates noted in the announcement, industrial processes account for over 20 percent of emissions. If technology can reduce even a fraction of these emissions, it could help keep global warming at bay. Heliogen also has bigger ambitions. Ultimately, it hopes to reach temperatures of 2,732 ° F, which would be hot enough to produce hydrogen and synthetic gas. At this point, clean energy would have to be used to generate more clean energy ̵
