The Indiana Department of Transportation (INDOT) plans to develop roads that will be able to charge electric vehicles (EVs) while you drive on them. Though the concept is not new, it has proved to be expensive and inefficient till now.
The researchers are testing a new type of cement with embedded magnetized particles that aims to provide efficient, high-speed charging at standard roadbuilding costs.
The research is being led by INDOT with Purdue University and German company Magment, with funding from National Science Foundation.
The magnetized cement named “magment” will deliver wireless transmission efficiency of up to 95% and can be built at standard road building installation costs.
The project will be carried out in three phases, with the first phase testing its workability in the lab, the second phase testing the product on a quarter-mile section of road, and the final phase testing concrete’s capacity to charge heavy trucks operation at high power.
After achieving success in the final phase, INDOT will use the technology to electrify an as-yet-unknown stretch of public interstate in Indiana.
Magment’s website shows that the product has a high degree of thermal conductivity and can withstand all weather conditions. It also mentions that the magnetized cement could be made locally via licensing (if any other state wished to employ it).
The project will be part of the Advancing Sustainability through Power Infrastructure for Road Electrification (ASPIRE) initiative.
