Ask HN: What under-the-radar technology are you excited about?
Heat pumps and better insulation. It&#x27;s magic how heat pumps pull heat out of thin air. I honestly think part of the reason they are not adopted as much is people can&#x27;t understand them and don&#x27;t trust them because of their ignorance. Insulation seems pretty boring until you start to realize how much energy can be saved by modern insulation.
