It's difficult to work when you're heating up like a Wesley Snipes in tax court. To cool down without raising the earth's temp, check out Dyson's line of Air Multipliers which do away with traditional blades and instead draws in surrounding air and then multiplying by 15. What you get is a smooth, constant, steady stream of air. If that doesn't cool you down at work, drop what you're doing and take a lunch break.
