That's the idea behind road charging, roads that charge your vehicle as you drive over them.
Sci-fi. Nope. This is a new reality that Indiana will test some day soon. Indiana's Dept. of Transportation and Purdue are working with German firm Magment, a German firm, which makes magnetized cement called magment (small "m"). "The three-phase project will test whether Magment's product is capable of charging moving vehicles at greater than 200 kilowatts." (Source: Autoblog.com)
"INDOT will build a quarter-mile stretch of magment highway at an undisclosed location for real-world testing on heavy trucks at 200 kilowatts and above. And if that's successful, INDOT will build another section of magment highway, this time on one of the state's public roads."
So, when the future gets here, you might be able to drive from coast to coast on magnetized cement, just like you do today on asphalt.
Pretty cool idea, we think!
