Thanks for your message mass/energy/light. I got to clarify some
notions about these things. It certainly reenforced my feelings that
the key to FE (and real space transportation) is not to try to move the
actual electrons (ultimately bulky and noisy) but their potententials or
virtual electrons as per T.Bearden theories or as demonstrated by B.
Fogal (haven'succeeded in firing one of those transistor yet).
