Are these based on the Seebeck or Peltier Effect? If so, then it is probably just an increment on existing technology. You can go to your local variety store and buy a 12VDC camping cooler based or Peltier junction solid-state heat pumps.

Or is this truly something new?

Change “comprised of” to “composed of.”

This solid-state heat pump technology was old hat decades ago. You can buy such heat pumps off the shelf today. Some picnic coolers for use in cars (12 volt) are made with this technology. When they were introduced many years ago they were hailed as using the latest new technological developments from NASA, although even then the technology was basically well known though NASA had funded useful improvements. There is nothing at all in this article that merits the description of a ‘new technology’.

Where’s the efficiency numbers?
“ready for launch in 5-10 years” = “we have a tech we think is kewl but have no idea how to manufacture it in quantity or how to market it”

Don’t have to wait 5-10 years, buy them now from lairdtech dot com, search for thermoelectric-modules

Where is a useful link to the source of these news? Just a *single* useful link. Is that too much asked in the age of the Internets?
