I'm just wondering why this isn't more developed by now? It's a great way to use up nuclear fuel and the batteries are essentially reusable.

In the late 1980’s I sold watches that had a tritium dial.

They were a lot brighter than radium dial watches and did not have to be exposed to sunlight to glow.
