MIT Wristband Could Make AC Obsolete

19. Make active thermal clothing or individualized atmosphere

I have long thought there would be a future for clothing that actively heats or cools the person, allowing us to adjust the climate of a razor-thin layer of air around a person instead of adjusting the climate of an entire room or house. Especially for cooling, since regular clothing can insulate and warm a person but it cannot cool.

The extreme example would be a climate-controlled space suit, but I was thinking something would eventually evolve that is functionally similar but unobstrusive.

Maybe not even clothing but a tiny atmosphere or air bubble that somehow is attached to an individual. Obviously it would have to have intake and exhaust for fresh air to breathe, or maybe the nose and mouth would be outside the bubble.
