There was something magical about the construction that Berlin allotment gardeners used to light some gazebos after the Second World War. And, depending on the point of view, it was a brilliant technical trick or simply criminal. Copper wires were stretched to the ground from flagpoles or trees, plus a couple of coils and light bulbs that began to glow – without a battery or a connection to the power grid. The allotment gardeners harvested the electrical energy from the air: in the vicinity of the large radio transmitters, they were able to tap the transmission power of the antennas with the copper wires and use the voltage generated to generate electricity from nothing.
