Electric vehicles are getting a lot of buzz. Yet sales of electric vehicles, or EVs, are expected to amount to less than 4 percent of passenger vehicle sales in the United States in 2021.<\/p>\n

One reason: the inability to easily recharge on long trips, known as range anxiety. And the concern is valid: Range, charging time and availability of charging stations all still have a long way to go.<\/p>\n

EVs are getting a boost, though: They are prominently featured in a $7.5 billion initiative from the Biden Administration, signed<\/a> by the president earlier this month, with the goal of building a nationwide network of a 500,000 high-speed electric vehicle charging stations by 2030. (Currently, there are about 43,000 charging stations, according to the U.S. Department of Energy.)<\/p>\n

But that would solve only part of the problem, in part because charging times are still lengthy. The real sweeping change in the next decade may address that: roadways that electrically power cars as they travel, using a technology known as inductive charging. <\/span><\/p>\n<\/div>\n<\/div>\n

In July, the Indiana Department of Transportation and Purdue University announced<\/a> plans to develop the world\u2019s first contactless wireless-charging concrete pavement highway segment.<\/p>\n

The project is being undertaken by an engineering research center called Advancing Sustainability Through Powered Infrastructure for Roadway Electrification (ASPIRE)<\/a>. It is funded by the National Science Foundation.<\/p>\n

\u201cOne of the major barriers to electrification is the range anxiety. This technology is intended to solve the problem,\u201d said Nadia Gkritza, a professor at the Lyles School of Civil Engineering and ASPIRE campus director at Purdue University. \u201cIn simple terms, the vision is to bring the charge to the vehicles, rather than having the vehicle stop at charging stations to recharge.\u201d<\/p>\n

The multiyear project will use a magnetizable concrete technology \u2014 developed by the German company Magment<\/a> \u2014 enabling wireless charging of electric vehicles as they drive.<\/p>\n

The technology works by adding small particles of recycled ferrite \u2014 a ceramic made by mixing iron oxide blended with slivers of metallic elements, such as nickel and zinc \u2014 to a concrete mixture which is magnetized by running an electrical current. This creates a magnetic field that transmits power wirelessly to the vehicle.<\/p>\n<\/div>\n
