German designer creates device that absorbs energy from electromagnetic fields
Depending on the field strength, it is possible to charge a small battery per day
In the world we live in, information is a fundamental part because it greatly helps in communication and in the way people organize themselves. And for it to flow, it needs to be transmitted in different ways. One of them is something we constantly produce: electromagnetic fields. They are the junction of electric and magnetic field vectors to generate electrical energy. They are common in places such as power transmission lines, but also in many objects that have a battery or use electric light.
However, German designer and photographer Dennis Siegel developed a device that exploits electromagnetic energy and manages to “touch” various electromagnetic fields, harvesting it. With this, it is possible to absorb energy from devices such as a coffee machine, cell phone or energy cables located on poles and store it in a common battery. To do this, simply hold the “Electromagnetic Harvester” directly in the electromagnetic field and, depending on the intensity captured, it is possible to charge a small battery in a day. The size of the power is identified by a light-emitting diode (or, in English, LED ) that is positioned on top of the device.
As there are different electromagnetic fields, the designer created two types of devices that harvest energy. The first is smaller, suitable for low frequencies, less than 100 hertz, which can be found in networks in general that have an average of 50 hertz to 60 hertz. And the other that suits low and high frequencies such as radio transmissions, around 100 megahertz, the Global System for Mobile Communications ( GSM ), which varies between 900 and 1800 megahertz, and Bluetooth.
If there is an electric current flowing, you can be sure there is an electromagnetic field. That's why it's possible to harvest energy from both a toaster and a transmission tower. The only care that must be taken is the field strength and frequency, which goes up to 2 gigahertz.
Dennis, who studied at the University of the Arts in Bremen, believes that the exploration of these sources can raise awareness in people that these electromagnetic spaces are there to help and even supply the energy needs that are increasing each year with population growth. .
