Electricity moved through air in a groundbreaking experiment conducted by scientists in Finland, proving that power does not always need plugs, cables, or traditional wires. By combining sound waves, lasers, and radio frequencies, researchers showed that electricity can travel through open space in a controlled and safe manner, leading to the concept of an “acoustic wire,” an invisible path that guides energy through air.
However, this experiment is not about unlimited or floating power; instead, it emphasizes precise control, safety, and efficiency without physical contact. As a result, the findings place Finland at the center of global wireless power research and clearly demonstrate how known scientific forces can shape and deliver electricity through air.
What actually happened in Finland
In Finland, scientists successfully demonstrated that electricity can be transmitted through air. They did not rely on copper cables, plugs, or sockets. Instead, they used a mix of ultrasonic sound waves, laser beams, and radio-frequency energy.
First, they generated high-intensity ultrasonic sound waves. These are sound waves above the range of human hearing. When these waves move through air, they slightly change air density. As a result, the air forms a stable path that energy can follow. This path works like an invisible wire.
Next, the researchers used lasers. Lasers can carry energy in the form of light. When the laser hits a suitable receiver, that light converts into a very small amount of electricity. This method allows energy to move without physical contact while keeping the system electrically isolated and safe.
At the same time, radio-frequency energy played a role. Radio waves already exist all around us, coming from communication systems and other sources. The researchers showed that this ambient energy can be collected and turned into usable electricity, especially for very low-power devices.
Together, these methods created a working proof-of-concept. The experiment showed that electricity can move through air in a guided and controlled way. It was not random, and it was not dangerous. Each step was carefully measured and calibrated.
The experiment did not aim to power entire cities or large machines. Instead, it focused on showing that the idea works. By doing so, the scientists proved that traditional wiring is not the only way to move electricity from one place to another.
Who developed the idea and how does it work
Research teams from Finland’s leading universities carried out this experiment in collaboration with private technology groups. Their work brought together different fields, including physics, electrical engineering, and material science. The goal was practical testing, not just theory.
The key concept behind the experiment is known as the “acoustic wire.” This is not a physical object. Instead, it is a path created in the air using ultrasonic sound waves. These waves organize the air in such a way that tiny electrical sparks can travel along a specific route.
Electricity usually needs a solid conductor, such as copper. In this case, the sound waves acted as a guide. They shaped the air so that electrical energy followed the path instead of spreading out. As a result, the electricity moved safely without touching any solid material.
Lasers added another layer to the system. A laser beam can send energy over a distance as light. When that light reaches a receiver, it converts into electricity. This process allows energy transfer without metal connections and reduces the risk of electrical shock.
Radio-frequency harvesting completed the system. Many environments already contain radio waves. The researchers showed that devices can collect these waves and turn them into small amounts of power. This is especially useful for sensors and smart electronics that need very little energy.
All these elements worked together. The sound waves guided the path. The lasers delivered energy. The radio waves provided additional power. The result was a controlled flow of electricity through air, without wires.
Does electricity flowing through air break the laws of physics
At first glance, sending electricity through air may sound like it breaks the laws of physics. In reality, it does not. The Finnish experiment follows known scientific principles very closely.
This is not the same as electricity floating freely through space. The energy does not move randomly. Instead, the scientists guided it using carefully designed fields. Ultrasonic waves shaped the air. Lasers carried energy as light. Radio waves supplied small amounts of ambient power.

In simple terms, the electricity still follows a path. That path is just invisible. It exists because sound waves and electromagnetic fields shape the environment around them. The experiment also focused strongly on safety. The energy levels were controlled. The systems were designed to avoid harmful exposure. The electricity delivered was small and precise, suitable for low-energy devices.
Wireless charging systems already exist for phones and wearables. However, this Finnish experiment went further by combining multiple methods into one controlled system. Using sound, light, and radio waves together at this level is rare.
The work does not claim unlimited power or instant charging of everything. Instead, it shows that electricity can be directed without metal wires. It also shows that imagination, combined with careful science, can challenge long-held assumptions.
By proving that guided energy transfer through air is possible, the experiment expands how people think about electricity. Wires are no longer the only option. Controlled fields and invisible paths can also move power safely and predictably under the right conditions.
