Regarding the compressed-air problem you mentioned, have you seen LightSail Energy's (http://lightsailenergy.com http://lightsailenergy.com) solution to it?
"Our innovation: an elegant method of capturing this heat energy and regenerating useful energy from it. We inject a fine, dense mist of water spray which rapidly absorbs the heat energy of compression and provides it during expansion."
Maybe one of the founders, @DaniFong (https://news.ycombinator.com/user?id=DaniFong https://news.ycombinator.com/user?id=DaniFong), can chime in.
- DaniFong 11y agoYou've pretty much got it. The author mentions us actually. The parent commenter does accurately locate the challenge to date with compressed air energy storage, but we've directly and successfully targeted that loss channel :-)
- infogulch 11y agoThanks for replying. Most compressed air systems attempt to pull as much moisture out of the air as possible to prevent corrosion, but your solution to the heat problem means actively making the air and interior even more wet. This wouldn't be a problem in the short term, but your product is meant to be used over a very long period (~20 years); how are you approaching the issue with corrosion?
