Passively cool (or warm)

• The idea is very much simple. Engineering probably isn't.
• If the sun shines stronger it is hotter, but there is also more solar power for cooling.
• 
• The idea is not to cool huge skyscrapers...but to constantly use solar power to cool or heat spaces toward desired temperature.
• Install it (on the roof), set the desired temperature and forget it exists.

1. Follow the prices and development of such systems.
2. When the time is right (electricity gets expensive enough) start importing.

• I hope this doesn't make me a tree hugger :).
