As a person trained in computer science I can tell you that computers are fascinating. They are some of the most amazing things human beings have ever invented, the problem is that they are not very eco-friendly. They use a lot of nasty chemicals when you make them, and when you run them they make a lot of heat. The part of a computer that makes a lot of that heat is the CPU (central processing unit). This “brain” of the computer usually has a big noisy fan attached to it, which just blows the hot air out the back of the computer where it goes towards making your room really hot in the summer.

While the fans that are attached to these fans are pretty efficient, a much more efficient use of the heat of the chip to power a device that would cool the fan.
