comment What is the voltage difference between the Moon and the Earth?
Thats a good point. However I do think that a current can flow if electrons are released from the surface. This can happen if the field strength is great enough to locally ionize the surface material, after which electrons will be accelerated by the field, even without atoms in the space to be ionized. In a vacuum tube the electrons will flow even without a space charge if enough voltage is provided.
