Electromagnetic Harvester
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.
There are two types of harvester for different frequencies: a smaller harvester that is suitable for lower frequencies below 100Hz which you can find in the general mains (50/60Hz, 16,7Hz) and a bigger one that is suitable for lower and higher frequencies like radio broadcast (~100MHz), GSM (900/1800MHz) up to Bluetooth and WLAN (2,4GHz).
