Diamond Thermal Conductivity: A New Era in Chip Cooling

Assuming this becomes easier and cheaper to do as the technique matures, a different use of this could be to help with cooling solar PV cells. Despite it being desirable (in terms of overall energy output) to put solar panels in places where the sun's energy is felt the strongest, solar panels tend to work the most efficiently when they're cool. By making it easier to efficiently cool solar PV cells, it may help provide a small boost in overall solar output.

Putting on my frowny-faced principal engineer hat: we need someone to do the calculation of cost of manufacturing vs the amount of money saved by increasing energy efficiency.

Before you put on your frowny-faced principal engineer hat, you should put on your reading glasses. Try reading the first statement I made again...

"Assuming this becomes easier and cheaper to do as the technique matures"

In other words, what I'm suggesting is a potential future use if the cost comes down.
