Of course.It takes energy to defect particles or to change the shape of a crystal, doesn't it? You would be observing/measuring effects and *deduce* that there is a potential, but that is different from observing/measuring the potential itself, isn't it?Yes, it takes energy. It doesn't take current.
Actually, it does. Energy (power) is voltage * current. Without current, you have no energy.
BTW, I agree a bit with an earlier poster that you a being a bit of a twat. This mailing list isn't really appropriate for epistemological discussions.
Me, three.
