It’s crazy that our grids are still held together by the speed of a physically spinning generator. It’s like driving your electric motors with brush motors or using analog tape instead of digital audio, POTS instead of VoIP. A perfectly reasonable but still obsolete technological anachronism that will be gone within our lifetimes.

Watching the enormous progress we’re making on upgrading our energy infrastructure is definitely one of the most exciting things happening in tech. People seem determined to stick to old ideas.
