Harnessing Error-prone Chips Trades Computational Accuracy for Energy Savings

October 31, 2014 2:09 pm | by Larry Hardesty, MIT | News | Comments

As transistors get smaller, they also grow less reliable. Increasing their operating voltage can help, but that means a corresponding increase in power consumption. With information technology consuming a steadily growing fraction of the world’s energy supplies, some researchers and hardware manufacturers are exploring the possibility of simply letting chips botch the occasional computation.

Renewable Energy: The Power of Salt

August 26, 2014 4:27 pm | by Jennifer Chu, MIT | News | Comments

Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT. The researchers evaluated an emerging method of power generation called pressure retarded osmosis, in which two streams of different salinity are mixed to produce energy. In principle, a PRO system would take in river water and seawater on either side of a semi-permeable membrane.
