The inner tubes are insulated from each other andthe 1 inch one is connected to the bolt through the bottom. The delivery tube and outer case must be isolated from the restof the car. The deliver tube runs towards the carby or throttlebody. The cell is filled with specially charged water and the timingis adjusted over a couple of days . At the end the fuel is cutoff all together and the motor will be running with a advancebetween 25 and 80 degrees.
Castiron engines are the hardest todo.
This photo taken just a current is beig applied notice the gas bubbles being formed, a few seconds later the entire glass is filled with a white mass of bubbling foam Aluminium is the easiest to do. Some aluminium engines one takea day of driving to completely cut over. The exhaust is ice cold,the radiator has ice on it and it has twice the power of a petrolengine. I believe it may be worthwhile to remove the water fromthe block and replace it with Auto Transmission Fluid as it freezesat a much lower temperature. I would expect that the water pump vanes would need to be clippedor drilled to decrease efficiency and drag in the oil.
