Plus: Trump’s China AI chips U-turn hasn’t gone down well with Democrats This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. This startup wants to use the Earth as a massive battery Texas-based startup Quidnet Energy just completed a test showing it can store energy for up to six months by pumping water underground.
