"power density" refers to the amount of power or energy produced or transmitted in a given area or volume. It helps us understand how concentrated or intense the power is in a specific space. Full definition
The data will help advance gas turbine engine designs for higher power density and efficiency, scientists said. (scienceandtechnologyresearchnews.com)
This explosion in power density does not come without costs, though, and is causing increased temperatures inside and around the chips. (treehugger.com)
The researchers were able to increase power density by increasing the number of batteries, so that this method is scalable to something that might be commercially attractive. (sciencedaily.com)
