Chinese Scientists Generate Electricity from Blood Flow

Janina Lazo-Cruz — Tue, 12 Sep 2017 16:40:18 +0000

The conversion of kinetic energy to electricity has been appreciated and applied in huge hydroelectric power plants, water dams, and wind mills. Chinese researchers from Fudan University have recently shown that the same concept can be applied to electric power generation in bloodstreams for medical devices applications, which has been tested successfully with frog nerves.

Researchers Harness Photosynthesis to Produce Energy

Leigh Hutchens — Tue, 14 May 2013 03:18:22 +0000

For years, scientists have been trying to harness the energy of photosynthesis since plants themselves are the perfect solar technology. Plants use photosynthesis to produce energy at nearly 100% efficiency. Researchers at the University of Georgia have been able to tap into photosynthesis directly to produce electricity. They discovered a method to interrupt photosynthesis to […]

Recently Discovered Nanocoating Makes Heat Transfer Happen Much Easier

Ovidiu Sandru — Thu, 10 Jun 2010 13:04:42 +0000

The action of cooling things down plays a critical part of any mechanical or electric system, because the inevitable heat, produced by friction, is the number one cause of almost instant failure. So far, different methods that cool systems have been discovered, but not to the extent of performance that engineers dream of building their computers or mechanical devices (cars, for example).
