I’m always annoyed by the waste of cooling (or heating) a whole building when what we really need is just our body temperature to regulated. My thoughts drift towards clothing that has cooling built in, but become my usual muddle of 1/1000th baked ideas.

But try putting a reusable cooling pack right on your body, it’s pretty great when you’re overheating.

Back mounted compressor that runs cooling pipes to your underwear, that could be amazing!
