You could set up some poles on the Moon's surface, string heater wires on one set, some chicken wire for the grid and a many square meters of aluminum foil for the plate. In 1/6 G gravity, imagine how big it could be. A ten-meter high triode, maybe.Actually,I think G.O. Smith had something like this in a story long ago.
