PML Impact: April/May 2023

The latest news from the Physical Measurement Laboratory (PML) at NIST.

View As Web Page April - May 2023 Novel Way to Convert Heat to Electricity If perfected, the technology could help recoup some of the heat energy that is wasted in the U.S. at a rate of about $100 billion each year. Silicon sheets could be wrapped around steam or exhaust pipes to convert heat emissions into electricity that could power nearby devices or be delivered to a power grid. Another potential application would be cooling computer chips.
