Electric vehicles using electrified roads. Needs smaller battery

IMO, the biggest question will be electrified roads.

Also means electric trucks become profitable FAR sooner.

Hope it works. I see thousands of miles of expensive copper underneath each lane of every road, fully energized at all times, and tremendous losses due to resistance at every mile. So maybe where electricity is “free” it could work, otherwise, I have questions.

fully energized at all times, and tremendous losses due to resistance at every mile.

It is not fully energized at all times, only when in use by an identified user (to charge them for power used), so no losses there. Losses to resistance happen at every level–charging and using battery power. Needing ALL THOSE CHARGERS (so lots of resistance getting the power to the charger), and so on. Copper would be tempting for thieves, but tech should be able to create something that helps prevent it. Maybe not use copper where it is readily accessible.
