Goodbye to copper and hello to wireless electricity: The US presents one of the greatest advances in history.

We saw firsthand how dependent we are on electricity during the national blackout at the end of April, as this energy is key to virtually everything we do and need.

Many things are needed to generate electricity, but one essential element that cannot be missing is copper, as it is the key element for transporting electricity from the grid to our homes. Because human beings are tireless and always looking to turn things around, for many years, researchers and experts in the field have been trying to find alternatives to this material.

Although it seemed like an "impossible mission," the Persistent Optical Wireless Energy Relay (POWER) project of the United States Defense Advanced Research Projects Agency (DARPA) has carried out an experiment that will completely change our view of electricity, especially because it seems like something out of a science fiction movie.

During the experiment conducted at the White Sands Missile Test Range in New Mexico, researchers demonstrated that it was possible to transmit electricity wirelessly over long distances . Specifically, they managed to send more than 800 watts to a receiver located 8.6 kilometers away using a laser beam , an amount that would allow a microwave oven to function normally.

The key behind this technology is the ability to send energy through the air using light, with the goal of converting it into electricity. This is possible using an infrared laser, which, when pointed at a mirror, directs this light to solar cells, which transform the light into energy.

While this breakthrough is still in its early stages, meaning it is far from being applied in the real world, this achievement paves the way for one of the greatest achievements in history, as it would completely revolutionize the way electricity is sent.

This project seeks to eliminate dependence on large fuel supply chains and the need for expensive power lines to deliver energy to combat zones, remote regions, or locations affected by natural disasters.
