I avoided chrome for a long time. Finally I made the switch because FF was getting too slow on old computers back in the day. Lasted for maybe five or six years before I started getting some bad vibes. Why am I letting google run the web browsing software I'm using? This can't/won't be good in the future.
At least five years ago I made the switch back to Firefox, and haven't looked back. I love having adblocking that works (I use a router level ad block and ublock origin just in case to ensure I block almost every ad on the internet lol).
I'm honestly surprised it took people this long to decide to move away from Chrome.
TL/DR - they're using mini solar tower collectors to concentrate and collect sunlight to charge PV panels. This produces a lot of excess heat (enough to melt steel) - the heat is pumped away via water into an underground vault where the heat is stored until the evening where the heat is converted back into electricity using conventional off-the-shelf materials and hardware.
