In a series of breakthrough experiments, scientists have demonstrated the ability to transmit electricity wirelessly through the air—using nothing more than high-intensity ultrasonic sound waves and focused laser beams.Researchers at the University of Helsinki and University of Oulu are placing Finland at the forefront of this emerging wireless energy revolution. One of the most visually striking innovations involves acoustic plasma channels: powerful ultrasonic waves create invisible, low-density paths in the atmosphere that guide electrical discharges (sparks) precisely along a controlled trajectory. This "acoustic wire" acts like an invisible conduit, allowing electricity to jump through open space without any physical conductor.Still in the lab phase, the technique hints at transformative applications: contactless charging, plug-free smart surfaces, dynamic electrical connections in robotics, or even temporary power links in hard-to-reach environments.Parallel efforts are pushing the boundaries further:- Power-by-light systems use high-powered lasers to beam energy across distances to photovoltaic receivers. These setups provide complete galvanic isolation—no electrical connection between sender and receiver—making them ideal for hazardous settings such as nuclear facilities, high-voltage substations, underwater operations, or aerospace platforms where traditional wiring poses safety risks.- Radio-frequency (RF) energy harvesting is turning ambient electromagnetic waves (from Wi-Fi, cellular networks, broadcast signals) into usable power. This "Wi-Fi for electricity" approach could eliminate billions of disposable batteries in low-power Internet of Things (IoT) devices, sensors, wearables, and remote monitoring systems, drastically reducing electronic waste and maintenance needs.Taken together, these Finnish-led advancements point toward a profound shift: a future where energy infrastructure becomes more flexible, decentralized, and invisible—free from the constraints of copper cables, plugs, and physical connections.While challenges remain (efficiency, safety at scale, regulatory hurdles), the convergence of acoustic, optical, and RF wireless power technologies signals that the era of truly cable-free electricity may arrive sooner than expected.[University of Helsink.

Cuba’s deputy foreign minister said to NBC news its military is preparing for possible US aggression, warning it would be “naive” to ignore the threat."We truly hope that it doesn’t occur. We don’t see why it would have to occur, and we find no justification whatsoever.”
