Is it possible to transmit electricity through the air over long distances?

2025-08-17

While the concept of transmitting electricity through the air has captured the public's imagination since the time of Nikola Tesla, it is not a feasible or efficient solution for a large-scale power grid. While electricity can be transmitted short distances without wires (e.g., through inductive charging), long-distance transmission through the air faces significant technical and efficiency challenges.

  • Significant Energy Loss: Transmitting power through the air over long distances is highly inefficient. The energy would dissipate rapidly as it travels, with a significant portion being lost to the atmosphere and the surrounding environment. This makes it a very impractical and costly method for bulk power delivery.

  • Safety Concerns: High-power wireless transmission would pose immense safety risks to humans, animals, and the environment. The high levels of electromagnetic radiation required to transmit power could be hazardous to living organisms and could interfere with other electronic systems.

  • Feasibility and Cost: The infrastructure required for a wireless power grid would be astronomical to build and maintain, far outweighing the cost of the existing wired grid.

For these reasons, the most efficient, safe, and reliable method for bulk power transmission remains the use of high-voltage conductors, which is the foundation of our business.
