Energy flow can be traced from a stream or river to a hydroelectric dam and thence via the turbine and generator to the electricity transmission lines. A particular aspect of energy, its «sensory imperceptibility» is examined. The energy flows with the water and circulates through the moving parts of the machines to the electrical conductors which carry it away to the consumer. The energy flow moves as if in a space which is inaccessible to human senses. George Adams shows that energy as a physical quantity, the product of force and distance, is on the border of the perceptible Euclidean space and the imaginable «counterspace», to which he assigns etheric forces.
