In July 2025, the company completed an experimental campaign, a key opportunity to test the performance of the technology and verify its operation at a distance of 120 m in a controlled and repeatable environment.

The experimentation, coordinated by CTO Tommaso Aresi, aimed to analyze in detail the behavior of the laser beam during energy transmission to electronic devices. In particular, the team measured the system’s efficiency, the beam intensity, its divergence, and its ability to self-calibrate by precisely targeting the receiver.

A key step of the campaign was the long-distance charging of a light bulb as a demonstrative load, replaceable with several other devices. The tests conducted demonstrated the stable and continuous powering of the bulb at a distance of 120 m, confirming the full functionality of the system.

According to Aresi, one of the most innovative aspects of SunCubes’ technology lies in its ability to operate fully within regulatory limits, keeping user safety at the center of the design. “Our patent enables a new way of using lasers in everyday applications,” he says. “The goal is that no protective goggles are required for safe operation, without sacrificing performance.”

The success of the campaign opens interesting scenarios for several sectors: charging security cameras, drones in flight, remote sensing, and all applications that can benefit from a stable, contactless wireless power system.

The results achieved represent the basis for the next step in SunCubes’ path: transferring the technology to the products under development, including the Lucy and Light systems.

To share behind-the-scenes insights from the campaign with the public, SunCubes has produced a dedicated video that showcases the key moments of the experimentation and the work of the team during the tests, published on every social media platform.

With this campaign, SunCubes confirms its pioneering role in long-distance wireless charging and prepares for the next phase of technological evolution, with tests on dynamic drone charging in hovering and in motion already planned to begin this month (December 2025), bringing new opportunities for collaboration and application.
