3D Printable Thin Film Thermoelectric Generator is Flexible Enough to Install Anywhere
Posted by Benji Jerew in Thermoelectric on March 28, 2013
Most energy systems are extremely inefficient, but flexible thermoelectric generators could recover some of that lost energy and put it back into the system. If we’ve ever seen steam billowing from a cooling tower or felt the hot exhaust coming from an automobile, what we’ve really been seeing is lost energy. According to the US [...]

New Thermoelectric Tube by Panasonic Recovers Lost Heat Energy
Posted by Mila Luleva in Thermoelectric on March 25, 2013
The latest technology by the giant Panasonic, a “thermoelectric tube,” is being tested at their Northeastern Clean Center in Kyoto City for its power generating capabilities. The tube can produce electricity from hot water by creating temperature differences between the different thermoelectric materials with low and high thermal conductivity. The company claims that a termoelectric [...]

How to Build an Electricity-Producing Peltier Gasifier
Posted by Mila Luleva in Biogas, How to..., Thermoelectric on February 13, 2013
A gasifier works by decomposing organic matter in an oxygen-free environment at high temperatures and then burning the hydrogen that results from that decomposition. It is a smokeless, much cleaner way of providing electricity and/or heat without particle emissions and soot. The so-called “Fusion Jr.” Home Energy Reactor has an amazing potential to generate energy [...]

New Hybrid Thermoelectric-Photovoltaic Device Demonstrated at UTA
Posted by Benji Jerew in Solar Power, Thermoelectric on November 13, 2012
For decades, photovoltaic devices have generated electricity directly from sunlight. Thermoelectric devices generate electricity from heat energy. Both devices have found their way into various applications, from photovoltaic roof panels to thermoelectric energy recovery in vehicles. Both methods of electrical generation are fairly inefficient, but now, by combining these two properties, researchers at University of [...]

Practical Thermoelectric Power Possible with Newly Invented Material
Posted by Benji Jerew in Car industry, Thermoelectric on September 25, 2012
Energy efficiency, that is, the amount of usable energy in a given fuel, is based off a number of factors. Hydrocarbon fuels, for example, have a given amount of chemical energy, that, when ignited, can be used to generate electricity, or propel locomotives and passenger vehicles. Even in the most efficient motor vehicle, more than [...]
