Outdoor Air-Conditioning

When it's hot and sunny, we like air-conditioning. But we also like the sunny outdoors, breathing open air. What we really need is outdoor air-conditioning.

You've seen the Dyson fans, vacuum, and even hand-dryers, which make use of Coanda effect. Here we'd have an outdoor chair which would make use of Coanda effect to pass cooled/chilled air over a person seated in the chair.

The skin of the furniture would be porous, enabling the cool air to emerge from within, to cool the seated person while they're outdoors. The temperature would of course be adjustable, perhaps with a control panel built into the armrest.

(Technically, you could probably use it in winter too, passing warm air over the chair/person. )

There could even be air-conditioned couches, mattresses, beds, etc. The idea is to cool a person who is sitting outdoors, by passing the air-conditioned air over the person via specially designed furniture.
