Wired’ Roads Could Power Electric Cars As You Drive
A wireless electricity system could help people give a way to charge electric vehicles according to a new study and avoid the mess of cords.Researchers at Stanford University accommodated a theory from quantum physics to generate a wireless charger that does something other wireless chargers can’t: automatically tune the frequency of the radio wave — the medium that transports the power — to account for changes in the space between the charging pad along with the apparatus.
In an experiment, the group revealed that its system moved power with 100 percent efficiency up to about 27 inches (70 centimeters).”The range is fantastic for electric automobiles,” Sid Assawaworrarit, a doctoral candidate in electrical engineering at Stanford University, told Live Science. “The floor of a vehicle is about 20 centimeters [8 inches] away from the road’s surface. You can embed the charging pad.
