Not for space craft if what @MilderRichter says is right. To generate power from a peltier you need a temperature differential between the two sides. It is very hard to bleed off heat in space since it’s a vacuum. That means a temperature differential is very difficult to achieve and it takes power to do that. Which would necessitate more of these, which means a bigger or additional heat removal system, which means you need more of these, which means a bigger or additional heat removal system, etc, etc, etc.
What’s the specific energy and power? If it isn’t terrible, could be very good for things like spacecraft.
Deep space probes are already nuclear power sources.
Right now this is mostly a radio isotope heat source and a peltier device to convert the temperature differential to electricity.
Yeah, RTDs. But I don’t know if these semi conductor based ones would have better performance.

With all the CCP misinformation about them making 5nn chips, this could be another bullshit tech coming from the CCP.
According to the article, it outputs 100 micro watts at 3 volts. Apparently for 50 years.
So less than 150watthours over its entire lifespan?
