Re: TEDs enable cool (hot) stuff
It's good to know there are a lot more applications for the devices than I had initially thought. So people are not just making chillers for their 6-packs of beer.


Definitely a field to which I will pay more attention.

TEDs enable cool (hot) stuff
Hi Brad--there is a lot of interest in TEDs.  They are used more widely than most realize.  TEDs show in in things like DNA sequencers becuase it is easier to control temperature with them.  They are used in some opto-electronics becuase the lasers need to be temperature stabilized to stay on frequency, so the are held above ambient and actively controlled.  

There are several areas of research regarding power generation.  Efficiency is the big issue for any application where size/weight is a concern.  So in cars, people are working hard on high-temperature TEDs that can generate powr off the waste heat from the catalytic converter.  Likewise for large-scale power generation.

An interesting area of work is to increase the absorption of solar energy as heat directly onto TEGs (Thermo Electric Generators) to improve efficiency as compared to photovoltaics.

Brad, Thanks for the post.

Power Felt can be used as thermoelectric generators. Most thermoelectric generators are inefficient. But generators using waste heat produced by engines, solar energy, wind energy then low efficiency may be practical.
