Google.com is amazing.  I have a "Google Alert" set to email me when new webpages come appear which mention thermoelectrics.  Many of these hits concern "thermoelectric power plants", which includes anything that produces electricity by burning something (as opposed to hydroelectric, solar or nuclear, for example).

But here are some recent hits related to thermoelectric energy conversion:

• NASA To Accelerate Space Nuclear Power
  • NASA reportedly plans use nuclear power much more frequently, based on Stirling cycle nuclear power systems being developed by Lockheed-Martin and said to be four times as powerful as previously used RTGs.
• Nations Looking For a Piece of the Exploration Pie
  • China reportedly plans to use a Pu-238 Radioisotope Thermoelectric Generator for a lunar lander mission planned for 2012-2015
• Scientists Mark Cassini Saturn Probe's 10th Anniversary
  • Cassini has been out there 10 years now, and the RTG just keeps on going.
• Wireless EEG System Powered by Body Heat
  • EEG & radio need only 0.8 mW, provided by body heat and a TE generator
• Keep Your Lunch Fresh With the Power of NASA Technology
  • A TE beverage cooler with a digital LED readout.
• Thermoelectric generators go to infinity and way beyond
  • A blog piece on TE generators, with some nice links to pictures of generators going back to the 1800's.
• Thermoelectric cooler available from Warsash Scientific
  • A marketing blurb for a distributor of Marlow TE modules
