That's quite interesting, notarboca, I didn't think of that. But if the temperature-change method proves successful, I'm sure researchers will look for other ways to harvest energy on airplanes as well. That could be another way they do it.
Temperature change to harvest voltage is a good idea. These folks even have a working prototype. My thought is that there is a great build up of static electricity on an aircraft in flight (witness the static "wicks" on the wing trailing edges that help dissipate it). Wonder if this energy could be harvested as well?
