The omnipresence of electromagnetic fields is implied just by simple current flow. We are surrounded by electromagnetic fields which we produce for information transfer or as a by-product of electric infrastructure. Many of those fields are very capacitive and can be harvested with coils and high frequency diodes. Accordingly, I built special harvesting devices that are able to tap into several electromagnetic fields to exploit them and charge a regular battery. Thus you can gain energy from the power supply of a coffee machine, a cell phone or an overhead wire by holding the harvester directly into the electromagnetic field whose strength is visualized by a LED.
Depending on the strength of the electromagnetic field it is possible to charge a small battery within one day. The system is meant to be an option for tapping into already existing but unnoted energy sources. By exploring these sources it can create a new awareness of the invisible electromagnetic spaces while giving them a spatial dimension.
