Air conditioners are not usually solar powered because they use so much power you would need a large surface area of solar panels to keep it going. What’s interesting here is that the GreenCore 10200 solves this problem by using a battery pack that it recharges continuously throughout the day. (It can also be charged directly from the wall)

The GreenCore comes with a configuration that will not be enough power to run the air conditioner completely on it’s own, but what it will do is save you some serious money on your next power bill by doing it’s part and it can be combined with other solar panels to supply its complete power needs. The technology looks pretty promising and can be used in a variety of ways.

Control Freek has a new and unique tennis racquet that aims to prevent sweaty palms by including an air-conditioner in the handle. I suppose this is big news for the Tennis world because sweatty palms will lose you matches and hurt your grip.

No batteries required. It was specially designed to capture air in the handle every time you swing the racquet. That air comes out through the holes and onto your palm, hopefully improving your game. I’m not sure that this would work, but if you’re the sweattiest palmed Player on the court it will cost you $275 to cool off.
