Researchers from Sandia National Laboratories have developed a tiny silicon-based device that can harness what was previously called waste heat and turn it into DC power. It is a solid-state device with no moving parts to jam, bend or break, and doesn’t have to directly touch the heat source, which can cause thermal stress. It is also the size of a small finger nail !
Paul Davids, a physicist and the principal investigator for the study says, “We have developed a new method for essentially recovering energy from waste heat. Car engines produce a lot of heat and that heat is just waste, right? So imagine if you could convert that engine heat into electrical power for a hybrid car. This is the first step in that direction, but much more work needs to be done.”
What a useful invention that could recoup heat losses from engines and any other devices. This could have many applications, including millions of vehicles powered by internal combustion engines throughout the world, saving power and therefore lowering emissions !
Hope you have a good month
All the best
