Output of best betavoltaics per size?

[jim_990]

does anyone know what power output the best current betavoltaics can produce per size per volume/type/radioactivity of fuel? Are they capable of size for size equaling a normal battery? and if not what fraction of the way there? or are alphavoltaics more promising? I cannot find much of interest on t
his except on these 'crazy' 'antigravity' web sites, which i don't know whether to believe or not.

Looks like your researching ways to build an Electrical energy source from a Beta emitter.

I heard that Beta decay emissions can be accelerated by inducing a current into it, I don't know how true it is though.

another potential maybe be to look into a Beta emitting Dielectric material and build a Beta emitting Capacitor. The Dielectric could be a b- or an b-b-
and the charge plates could capture the emissions.

Can't wait for High K Dielectrics in a spray can. Hehe.

Hi there, from my research, the current best betavoltaics can produce power outputs ranging from a few microwatts to several milliwatts per square centimeter. However, this greatly depends on the type and amount of radioactive fuel used. Some betavoltaic cells have been able to achieve energy densities comparable to traditional batteries, but they are still not quite there in terms of size for size comparison. Alphavoltaics, on the other hand, have shown more promise in terms of power output and efficiency, but they are still in the early stages of development and not yet commercially available. As for the 'crazy' antigravity websites, I would take their claims with a grain of salt as they are not backed by scientific evidence. Hope this helps!
