If you can imagine a massive, horrifying beast with some 6 million miles of tentacles that costs up to $33 billion to feed and $5 trillion to replace, then you can imagine the U.S. electricity grid. But it’s a beast that can possibly be vanquished, finally. How? Magnetic induction and resonant coupling. Imagine a future where you can charge your electric vehicles while in motion using a charging mechanism built into the road on which it drives. Where the electrical grid is no longer reliant on power lines, utility poles, or expensive transformers and underground cables. A future where power companies stop chopping down trees that threaten nearby power lines. This might sound like a sci-fi movie, but the future you just imagined is nearly here, in the form of magnetic inductive coupling and resonant coupling. Magnetic induction, or magnetic inductive coupling, courtesy of Nikola Tesla, is already a […]
