[ExI] Magnetizable Concrete in Roads Could Charge Electric Cars While You Drive

[John Grigg]

"Installing the system is also not cheap at roughly $5 million per mile,
but according to the *New York Times*

*,* the German government thinks it may still be cheaper than having to
switch to trucks powered by hydrogen fuel cells or large enough batteries
to enable long-haul deliveries. The country’s transport ministry is
currently comparing the three approaches before making a decision about
which to support.

Even if the economics make sense, rolling out road charging infrastructure
will be an enormous effort, and it could take decades before every highway
can help top your car up. But if the technology keeps progressing, it could
one day make empty tanks a thing of the past."
