Solar-powered clothes: a Wearable Air-Con for Heat & Cold?

Running into science fiction

How would it feel to walk around wearing an air-con? Of course, we are talking about a tiny air-con that could fit inside your clothes and keep it warm of cool, depending on the temperature at the moment.

Clothes are really important for keeping our bodies at the right temperature and making sure we feel comfortable. They help us in different situations, especially when the weather keeps changing. For example, imagine going from a cozy room at a nice temperature (around 25°C) to a really hot place (over 36°C) or a really cold place (below 15°C) outside. If our clothes couldn't help us adjust quickly to these changes and either warm us up or cool us down, we would feel really uncomfortable, get sick, and maybe even die.

But it gets even tougher when we have to stay comfortable in really harsh environments, like the freezing polar regions or during space travel. In those places, the temperature can be really hot when the sun is shining, but super cold when it's dark.
