I came across something on the web, some guy put together what seems to be an electron accelerator, which is what I think similar to a particle accelerator but uses wire as a medium instead of a vacuum. You can see the schematic on page 29 of otto_ronette_TPU_ECD-V1_0.pdf
To get the electrons flowing in a circle you can use high voltage spikes which don't require much power. I found some math equations E=hc/λ and λ= h/p
E= energy
h= frequency energy constant
p= linear momentum of a particle
c= speed of light
λ= wavelength
doing some quick math it means E=pc which we already know obviously from E=mc<sup>2</sup>
which should mean you can get power from accelerating electrons if you can. They actually did light the bulb in this experiment apparently. In the pdf they say that it heated up a heat sink connected to one of switching transistors way beyond what seemed normal which to me suggested it started ionizing the aluminum by drawing away it's electrons in order to power the light bulb connected to the output. Remedied perhaps by a sodium based electron reservoir?
I donno, you guys figure it out. I'm not a scientist here
I'm having trouble posting the schematic. something wrong with the uploader on this site
