We’ve already established that your favorite tech company, from Apple to HP to Nintendo, and everyone in between, is being pressured to go green. While some of the tactics may be a bit silly, I think it’s safe to say that you’d rather see these companies green than not green, right? It makes us feel good about ourselves, that even though we’re buying hunks of plastic and metal—Lord knows what chemicals are in these things—the company in question is trying to make everything as environmentally friendly as possible. In the spotlight today is IBM, which continues to develop technology that could, one day, lead to zero-emission data centers.
The key to such data centers lies in a new cooling technology that IBM is currently toying around with.
Says Bruno Michel, an IBM research manager:
High-performance liquid cooling allows data centers to operate with coolant temperatures above the free cooling limit in all climates, eliminating the need for chillers and allowing the thermal energy to be reused in cold climates. [In so doing, Michel] demonstrated the removal of 85 percent of the heat load from high-performance compute nodes at a temperature of 60 degrees Celsius and compared their energy and emission balance with a classical air-cooled data center, a data center with free cooling in a cold climate zone and a data center with chiller-mediated energy reuse.
In other words, thanks to this fancy new cooling technology, IBM has to use less energy than it otherwise would have it.
The whole system reuses about 75 percent of the energy initially put into it. It’s that loss of only around 25 percent that makes the whole thing so efficient.
In other news, I have a massive headache. Is there an App for that?
