The super high power wedge shaped power transfer switch reminded me of my dad (high energy PhD) explaining how the super-colliders were experimenting with laser switched solid state relays capable of transferring enormous amounts of current with very little transition resistance. Unfortunately my father passed away so I can't get details from him. Maybe someone knows more about that technology. Or it never saw the light of day.
