New Remote Power Supply Solution in Finland

New Remote Power Supply Solution in Finland

Finnish engineers achieved a revolutionary breakthrough in late 2025 by successfully testing a wireless electricity system that transmits power through the air without cables, plugs, or physical connections. Elisa in Finland is using cellular basestation backup batteries as an AI-enabled virtual power station. Using the Radio Access Network (RAN) to run a Virtual Power Plant could save telecoms operators around 50% of their current. At the heart of Finland's wireless power system is the concept of using electromagnetic fields to carry electricity over a distance. Research teams from the University of Helsinki, University of Oulu, and Aalto University. With the launch of its new smart charging service, EV drivers in Finland can now participate in grid.

Remote power supply and anti-tracking for quantum communication

Remote power supply and anti-tracking for quantum communication

This research proposes a hybrid quantum communication system combining Quantum Key Distribution (QKD) and an Adaptive Anti-Jamming Module (AAJM) to secure power grid communications against interference. NASA SCaN is a program for all of NASA's space communications activities, which enables both NASA and non-NASA missions. , quantum repeaters, low-Earth-orbit satellite) connected by optical fiber cables to transmit information. It capitalizes on the no-cloning theorem, stating that quantum states cannot be copied. QS will allow for more accurate measurements and could offer higher accessibility than existing sensors (for instance.
