Until now, it has been widely believed that wires are necessary to transmit electricity from one place to another. Electricity is transferred through wires, powering lights, fans, and televisions. We've even seen wireless mobile chargers in this era. But the idea of electricity without wires seems unimaginable. But can you imagine that electricity can be transmitted through the air without wires? This question might seem strange, but scientists have made it a reality.
This feat has been accomplished by Finland, one of the happiest countries in the world. It's possible that in the future, we won't need to lay cables to get electricity connections in our homes. If this happens, you'll be able to power your bulbs, fans, and ACs without any wired connections. Let's find out how Finnish scientists achieved this marvel.
How was electricity transmitted through the air?
Scientists from the University of Helsinki and the University of Oulu in Finland have demonstrated the transmission of electricity through the air without the use of wires. The most remarkable aspect of this experiment is that it doesn't rely on just one technology, but rather combines three different aspects of physics. In this experiment, the scientists used high-intensity sound waves, lasers, and radio frequencies simultaneously. By combining ultrasonic sound waves and lasers, they created a pathway for electricity in the air. This experiment proves that devices can be charged without cables and plugs.
The unique combination of sound and light
To understand this technology, we need to understand the concept of an 'acoustic wire'. Scientists discovered that when high-intensity ultrasonic waves are emitted, they alter the density of the air. This creates a tube-like pathway in the air through which electrical sparks can travel safely. The laser system delivers energy to a receiver located at a distance, while radio-frequency harvesting converts ambient waves into electricity. Scientists say it's just like sending water through a pipe, except that here the pipe is made of invisible sound waves, and instead of water, electricity is flowing through it.
Will the hassle of cables and meters be gone forever?
This success in Finland suggests that the appearance of our homes could completely change in the future. You won't need to look for a wall socket for every device. The risk of wires breaking or short circuits could be reduced. Your phone or laptop, wherever it is in the room, will automatically charge wirelessly.
However, this technology is currently only being tested in the lab. Its effectiveness in real-world applications has not yet been assessed. Which devices can be powered by this type of electricity, and whether it will have any harmful effects on the human body, have also not yet been investigated. It may take time to bring this to homes on a large scale, but this discovery proves that it may be possible to deliver electricity to homes wirelessly in the future.
