When I come into the office on a Monday morning, its always colder than when I left on Friday despite heating being left on over the weekend. The reason is that the computers, printers and other devices that are used during a working day generate heat. It’s this sort of  bi-product heat that forms the basis of a green initiative from the Netherlands. Nerdalize is using the heat produced from computer servers to warm the homes they are installed in.

Data-centres filled with servers need cooling installations to handle the excess heat produced. Nerdalize offers an eco-friendly solution by placing individual servers in people’s homes where the heat can be useful, rather than a problem.

Homeowners can lease servers and the company pay for the electricity they use. Businesses can then buy the computing power they need from Nerdalize, saving between 30 and 55 percent on costs. The same energy is effectively used twice, creating a win-win situation.

I wouldn’t pretend that it’s easy, but I’m sure something like this could work in the UK too. Something for a very ambitious entrepreneur.
