Self-charging, thousand-year battery by startup NDB

"NDB is a nano battery technology that generates electrons by converting the radiation energy from the energetic electron. Energetic electrons released from the nuclide of carbon, carbon-14. ...the energetic electron release mechanism where a carbon-14 atom decays into nitrogen, an anti-neutrino (which are both harmless and clean) and an energetic electron.

The electron released then undergoes inelastic scattering generating a shower of electric charge in its track.

The 3D printed MOF/ACNO/Graphene Supercapacitor then stores the generated charge for later use. Due to this feature, NDB is a graphene battery technology as well as a nuclear battery."

This sounds too good to be true. Suppose they deliver this with the scale to be used any place, we could see a truly wireless world, even the tv could come with a battery that would last a lifetime, no power outlets would be needed anymore. What are your thoughts?

The proposed battery has a power output of 100 microwatts. You can probably get more output with a tiny photovoltaic cell (like the ones on calculators).
