COLLECTING & USING THE HEAT FROM YOUR HOME COMPUTERS TO CREATE USEABLE ENERGY

Harvesting heat from computers

One estimates that half of the energy consumed by data centres goes toward cooling computer processors, with most of the removed hot air simply being blown into the atmosphere. Instead, IBM sees that heat being captured & used to warm the air in other areas of the building, to heat water, or to be converted into usable electricity. The company has already developed an on-chip water-cooling system for computer clusters, which is being demonstrated on the Swiss Aquasar supercomputer. It utilizes a network of microfluidic capillaries inside a standard heat sink, attached to the surface of each chip. Water flows within a few microns of the semiconductor material, picking up heat from it, then piping the warm water to a heat exchanger – from there, the cooled water returning to the computers, using a closed loop system.

As with last year’s list, given that all of these technologies are already in experimental use, it’s a very good bet that they will indeed one day find their way into our lives. Whether that day is within the next five years, however, is another thing-time will tell
