https://lnkd.in/eMafcr8V Invention sheds new light on electricity generation By using gravity to generate energy more efficiently, architect Janjaap Ruijssenaars (Gravity Energy) and Ali Ghaderiaram (Civil Engineering, TU Delft) have achieved a breakthrough. Ruijssenaars has obtained global patent protection for the invention. During the years-long development from initial idea to construction of a prototype, he collaborated with parties from Twente and scientists from the Delft University of Technology (TU Delft). "The ancient Greeks already knew that when you bring two materials into contact, energy is released. However, they never translated that knowledge into a usable technique to, for example, harvest energy. It has only in recent years become possible with TENG (Tribo Electric Nano Generator). With the help of such a generator and an unstable weight, we have now made a new usable invention," says Ruijssenaars, who works as an urban designer for the municipality of Amsterdam in his daily life. Balloon Everyone is familiar with the phenomenon that when you rub a balloon against your hair, energy is generated. That is essentially how the prototype, a street lantarn, now lights up. "By adding a weight, attracted by gravity, you can generate energy with a greater impact. You only need a bit of wind, vibrations, or temperature difference. Anything that destabilizes the weight can serve as a source.’’ Convenient The gravity invention is especially useful in places where electricity is not readily available. Ali Ghaderiaram (Civil Engineering, TU Delft) demonstrated the technique in a wooden lantarn made by TimberLab. But it can not only produce light but also charge your phone or laptop, for example. Scientists at TU Delft see the most potential for this technology in sensors that require electricity to function. Ruijssenaars adds, "But of course, we will also explore how this technology can be made usable on a larger scale, such as for charging electric bicycles."
