Recycling is a HOT Topic

Newspaper clipping from the Straits Times about harnessing of heat as energy

It seems like there are many things that can be recycled, including waste heat! As reported in the Straits Times, a seemingly useless by-product of industrial processes, in this case, heat, can be used to cool buildings down. Sounds pretty contradictory huh?
Scientists at A*Star and Hitachi have discovered that the 440 degrees Celsius heat waste produced by diesel generators can be used to heat water, which is then used in a thermochemical reaction to get cold water of about 7 degrees Celsius that is circulated throughout the building. Sort of like an alternative to air conditioning.

I'm quite excited for what may be to come in the future; a revolution of the air conditioner! As many of you may have noticed, normal air conditioners have condensers outside the building which emits a fair amount of heat. Waste heat! (If you're not sure how air conditioners work, may I refer you to this page?) With this new discovery, I believe that many new and clean technology can be developed soon!
