Previously researchers from Ohio State University in the US pioneered the use of a quantum mechanical effect to convert heat into electricity. Now, they have figured out how to make their technique work in a form more suitable to industry.
The researchers used magnetism on a composite of nickel and platinum to amplify the voltage output 10 times or more. This time it was a thicker piece of material that more closely resembled components of future electronic devices.
Many devices, including car engines produce heat as a byproduct. This is usually called waste heat. Solid-state thermoelectrics aims to capture the waste heat inside specially designed materials to generate POWER, thus increasing overall energy efficiency.
The researchers were able to increase the output for a composite of nickel with a sprinkling of platinum, from a few nano-volts to tens or hundred of nano-volts. This required no nano-fabrication and can be readily scaled up for industry. Read the full article here.
