  Betavoltaics have been around for 40+ years. en.m.wikipedia.org/wiki/Betavoltaic_device

  This device generates microwatts. You’d need thousands of them in parallel to power a typical mobile phone.

  What’s the specific energy and power? If it isn’t terrible, could be very good for things like spacecraft.

    With all the CCP misinformation about them making 5nn chips, this could be another bullshit tech coming from the CCP.

    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 silicon based ones would have better performance.

    According to the article, it outputs 100 micro watts at 3 volts. Apparently for 50 years.

  Just what we need, radioactive materials in our waste stream.

  Meanwhile the Voyager proves launched in 1977 are still live and kicking. Yeah one of them is getting pissy at us but it’s still rolling.
