ok. this is talking about transmission of electricity. as far as I could dig thru the link, no mention of the source of the electricity??
So how does one avoid getting electrified?

Likely from the surrounding atmosphere if’n I remember my Tesla correctly.

Yes, Finnish scientists are making significant strides in wireless power transmission, developing technologies to send electricity through the air using methods like controlled magnetic fields, lasers, and sound waves to power devices without wires, moving beyond laboratory concepts towards practical applications for smart cities, drones, and industrial uses, though widespread adoption is still years away and presents engineering challenges.
Key Finnish Innovations:
Acoustic Wires & Lasers: Researchers are using focused ultrasonic sound waves to create pathways for electrical sparks and powerful lasers to deliver energy to receivers, offering electrical isolation for hazardous areas.
Magneto-Inductive Systems: Engineers are transmitting power via oscillating magnetic fields, similar to Wi-Fi for power, which could eliminate plugs for devices, vehicles, and sensors, says Facebook post Themech.mind.
Radio Frequency Harvesting: Low-power devices can capture ambient energy from radio signals, reducing reliance on batteries.
