If this technology is as good as stated, it could be a game changer for EVs.
That's basically saying "big if true". Inductive charging is barely fast enough to charge a phone laying directly on top of the charger in a reasonable amount of time, do you honestly think electric roads that inductively charge fleets of EVs are going to be ubiquitous?

It's fine. Even slow wireless charging can fill up a phone pretty well and can easily keep a phone running indefinitely. And the underside of a car is about five thousand times as big as the charging coil on a phone.

Now compare the distance between a phone and charging pad to the distance between the bottom of a car and the wires that are going to be buried under concrete. And forget about listening to Spotify while driving on these roads, the massive EMI those electromagnets will produce is going to take your reception to 0 bars.
- Dylan16807 4y agoIs it the distance that matters, or the ratio between distance and coil width? Because the latter comes across pretty favorably.
