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.
This video was made in response to Thom Powers (the documentary programmer for the Toronto International Film Festival, Stranger Than Fiction, DocNYC, and the Stephen Colbert-affiliated Montclair Film Festival) lobbying other film festivals not to play the film and trying to persuade journalists not to write about it or, if they had to write about it, to write about it negatively.
