The only condition: raise the heat during the nighttime. Aarhus University researchers created this environmentally-friendly, financially-winning system by using simulations and calculation models. Increasing the use of 10 percent more energy will save the same percentage on the heating bill. This […]

Fiberglass insulation is a key component to the green home. This barrier, in the winter, keeps the heat creeping through the walls to a slow crawl. In the summer, the insulation does the same thing, only keeping the heat […]

The circuit needs so little energy to run that it doesn’t even need a battery – it works by tapping the ambient energy. Spintronics harnesses the natural spin (up/down) of electrons. This up/down […]
