I think RTG stands for "Radioactive Thermal Generation" or something like that.

It is a hunk of plutonium that, on its own, glows at a high temperature.
Since the temperature of space is near absolute zero, there is a large temperature difference.
A relatively simple, dependable thermocouple generates electrical power from this temperature difference,
making a really long-lasting, dependable battery -- but not of the sort you want in your kid's toys :-)

For the few of us on the list that are idiots (ok, fine, just for me
then), what is RTG sourced power?
