all weather coat: human fur

Since, humans came from relatively hot parts of the earth our lean, hairless (mostly) bodies are not very well adapted to the cold. Since, we’re so clever we’ve made jackets (some times out of fur... well, before PETA, at any rate) But, even our most advanced jackets lack the weather responsiveness of real fur.

Take a bear, for instance, in the summer his fur is lighter and stands up more letting the air in. In the winter it thickens up-- if he swims (or if it rains) a layer ‘slick’ hairs stick together keeping much of the water from his skin.

To make a coat like this I say we use “smart” plastics. You know, the stuff that can be trained to remember different shapes depending on the tempeture?

If it’s hot, your coat turns white-silver and little air holes open for circulation. If it’s wet, the coat seals up water tight. If it’s cold, it turns black and a layer (or two depending on how cold it is) of air is formed between you and the cold outside world.

Plus, a coat like this would be a mighty fashion statement.

And you’d only need one. And no more putting on a coat in the morning and carrying it home because it got too hot, or any of that stuff.

Oh-- the thing here is to do climate controlled clothing, but without the moving parts-- or the need for a power source.
