It would not be too far off to surmise that 90% of the input energy goes to heating the outer casing of the fusor. (Electron bombardment due to conventional electrons flow as in a vacuum gas diode.)

Just off the cuff... Say you had a multi grid system. Then, arrange the charge on the outer most shell to repel the electrons before they hit...

I don't know, this is starting to look more and more like a multigrid vacuum tube, with screen grids and suppressor grids.. No wonder they went to ion guns.
