What's KB telling us?

I was researching Nuclear isomers on the weekend, as you do, and I found out that for Nuclear batteries: "As of 2004 the only isomer which had been successfully triggered was 180mTa", i.e. Tantalum.
https://en.wikipedia.org/wiki/Nuclear_isomer
"Hafnium and tantalum isomers have been considered in some quarters as weapons that could be used to circumvent the Nuclear Non-Proliferation Treaty, since they can be induced to emit very strong gamma radiation. DARPA has (or had) a program to investigate this use of both nuclear isomers. The potential to trigger an abrupt release of energy from nuclear isotopes, a prerequisite to their use in such weapons."...
There are 5 candidates for Nuclear batteries. It's not been shown, but if it could, and you owned a big source of the material supply for a Nuclear battery, well you would be the progenitor of "Dynastic wealth"!
Listen to this nut bag from 29min point. Silver is one the 5 candidates for a Nuclear battery and he makes it sound like the second coming:

For this long shot my money is on Tantalum.
PLS, Lithium with a Tantalum kicker.
