What if you made a head in which you could energize the element in a glow plug but at the same time adjust the compression once running. Might it be possible to eliminate or reduce drastically, (10%) the ether content or the ignition improver or both?

Or, what if you installed the filament from a glow plug into the contra piston in some way. Once started, would the element glow and would we get the same effect? I understand that heavy equipment diesel engines actually use a glow plug. Any merit to this idea? anyone tried it?
