The Erinamese ambassador is treated to a good meal and sent to view the defense grid.
Large Tesla Coils have been planted in the ground. They are rigged so that the circuit can only be completed when:
1) A switch in the concrete room below the towers is turned to the on position.
2) Land Mines altered so that when activated, rather than exploding, they complete the circuit.
Each tower is provided with a gasoline generator which gives its energy to the main Avalonian power grid when the tower is not activated (it takes a lot of power to make these work, so it's wasteful to have them running all the time and only for the towers.).
The towers cannot kill anything, an Avalonian engineer explains, because despite the high voltage, the towers do not produce enough amps to kill. Rather, anyone within its .35 km range is stunned (and will return to normal in a few hours). The range can be enhanced with greater power, but for the use which the towers are currently employed, .35 km is acceptable.
A field demonstration is given, and an Avalonian soldier has the privilege of being the first of any military personnel to be stunned by the defense grid. He returns to normal within normal time parameters.
This is time accurate. As the earliest date we're at is 1917, and I think we've moved past that. This is late 1800s, wiki it like you did for the government chart if you don't believe me.
Avalonia is willing to sell the technology to Erinaum under the sole condition that until such time as there is general peace between communist and capitalist nations, the technology only be employed along Erinaum's side of the Avalonian-Erinamese border. Avalonia will provide a Tower and its blueprints should the Erinamese government accept.
Avalonia offers to sell the Confederation tanks similar to Britain's Mark IV. for 10,000 pounds of lead and the refrigerator technology.
