WEST LAFAYETTE, Ind. — For the first time in the U.S., a roadway has wirelessly charged an electric heavy-duty truck driving at highway speeds, demonstrating key technology that could help lower the…
Research in Indiana lays groundwork for highways that recharge EVs of all sizes across the nation
Seems like a lot of energy will be lost when transmitting the energy wirelessly. How about we put up some wires that can deliver the energy more efficiently. After that, we can switch out the rubber tyres on asphalt for steel wheels on steel rails, such that we improve the energy efficiency further. This way, we can transport so much more stuff at a fraction of the cost.
Many science fiction stories fall back to using rail for transporting goods. Because it’s efficient. Unless we come up with literal magic like anti-gravity, rail it is.
