Thermoelectric Materials For Power Generation — New Insights Boost ‘Green’ Potential

The field of thermoelectrics might have just taken a notable step forward, especially with regard to “green energy” applications, thanks to new work from the University of Miami. Researchers there recently discovered the “surprising” properties of a metal named lithium purple-bronze (LiPB) — properties that make the metal very well-suited … [continued]

According to the newly published research, a very large thermoelectric effect can be created in a structure combining a ferromagnet (F) to a thin superconductor film (S) via an insulator (I), and where the superconductor is in the presence of a spin-splitting field due to the presence of a ferromagnetic insulator (FI) or a magnetic field (B).

Improved Thermoelectric Conversion Efficiency Via Use Of Magnets & Superconductors

An interesting development has occurred in the field of thermoelectrics — it’s been found that very high thermoelectric conversion efficiencies can be achieved by utilizing the “proper” combination of magnetic metals and superconductors. The findings are notable because previously most effective thermoelectric devices have been forced to rely on semiconductors … [continued]

Army Surveillance Drone Mashup With Thermoelectricity

No wonder the Army is so excited about thermoelectric technology, it’s the perfect energy scavenging system for those new surveillance drones you’ve been reading so much about. With a high power density and freedom from maintenance due to their lack of moving parts, thermoelectric systems are lightweight, durable, miniaturizable and … [continued]
