I'm not a scientist, but have an important problem I'm trying to solve. Unfortunately for one reason or another I can't go into too much detail on the reason but I can describe the generalities of the problem.
The setup:
If you had a simple electrical circuit. The circuit is broken by two thin flexible metal plates 2-5cm appart, designed so that when pressure is put on the upper metal plate it moves down to complete the circuit. The circuit is buried in the gound shallow enough that the weight of a man on the upper metal plate would complete the circuit.
The Question:
Would it be theoretically possible to create a charge through the 2-5cm of air to complete the circuit. This would need to be done whilst the circuit was still in the ground.
