New Antennae Harvests Lost Heat Energy
July 12, 2018 | Leave a Comment
Sandia National Laboratory researchers have developed a tiny silicon-based device that can harness what was previously called waste heat and turn it into DC power. The rectenna, short for rectifying antenna, is made of common aluminum, silicon and silicon dioxide using standard processes from the integrated circuit industry. Converting electrical power to heat is easy. […]

Hokkaido University researchers have more than doubled the ability of a material to convert heat into electricity. With progress in development it could help reduce the amount of wasted heat, and thus wasted fossil fuel, in daily activities and industries. The researchers and their colleagues in Japan and Taiwan have improved the ability to transform […]

New research at the University of Warwick shows waste heat can be converted to electricity more efficiently using one-dimensional nanoscale materials as thin as an atom. This suggests there may be a new way of generating sustainable energy. Led by Drs. Andrij Vasylenko, Samuel Marks, Jeremy Sloan and David Quigley from Warwick’s Department of Physics, […]

Better Thermoelectric Materials Use A New Process
May 31, 2018 | 1 Comment
Massachusetts Institute of Technology (MIT) researchers are using thermoelectric materials that when heated under high magnetic fields could produce record levels of energy. Improvements in thermoelectric materials – which spontaneously produce electricity when one side of the material is heated give rise to imagining being able to power your car partly from the heat that […]

A New Type of Thin Film Thermoelectric Cell
February 22, 2018 | 4 Comments
University of Tsukuba in Japan researchers have developed a way to recover environmental heat with a new type of thin-film thermoelectric cell, based on two different materials that show changes in their redox potential on cycling of temperature. The device is driven by differences in temperature and capable of recovering background heat energy at slightly […]
