Together with students Computer Science from Delft University of Technology (DUT), Nerdalize has developed a way to save even more energy!
Computer servers produce a lot of heat. In data centers, where a lot of servers are stacked together, it additionally costs a lot of energy to cool all these servers. In order to solve this, Nerdalize doesn’t place the computer servers in data centers, but in houses. Therefore the heat that comes off the server can be used to heat these houses. This way homeowners save up to 300 euros a year on heating and 3 tons of CO2 is saved per household per year. Additionally, companies save up 30 to 50% on cloud costs, because they do not have to pay for the overhead costs of building a data center.
This approach already causes a huge decrease in the energy usage. But it could be done even more efficient, is what DUT students Robert Carosi and Boris Mattijssen thought. For their bachelor final project in Computer Science, Robert and Boris found a way to utilize the heat that comes off the computer servers. Instead of using just any server to do a computation, they developed a way to always use the computer server in the house that needs the heat the most. For example in a place where it is a bit colder that day.
How does this work? Instead of doing one complete computation on one heater, this computation is cut up into smaller pieces. This way the computation can be divided over multiple houses. The pieces can then be computed in the house where the temperature is the lowest. When the wanted temperature is reached, the computation can be transferred to a house where the heat is still desired. This makes that the energy will always be used to its full potential.
Last Friday, the first of July 2016, Robert and Boris presented their project to family and friends. For their solution, they made smart use of Kubernetes, an open source system initiated by Google. This makes that not only energy can be saved, but our computer servers can run even faster and more efficient. A smart technological solution with a positive impact on the environment, that is what we love at Nerdalize!
