Sandia National Labs has discovered another way to extend Moore's Law:

Thermoelectric Nanowires to Cool Chips

However, before you panic and sell your POET Technologies shares, consider these quotes from the article:

• The trickiest part of threading thermoelectric wires on the topside of chips will be developing an excellent thermal contact that does not interfere with electrical functions. Unfortunately, this research will be expensive and involve a lot of supercomputer time as well as trial-and-error experiments to discover the right mix of materials and mounting techniques.
• “We need funding to carry on this work."
• Despite the progress made, Yelton claims thermoelectric materials are in their infancy and will be improved tremendously as their properties become better understood.

So as a POET shareholder you can still do what chips are supposed to do: stay cool.
