We are getting closer to charging cars while traveling

Finally, one of the biggest obstacles to loading moving vehicles has been overcome, which means we are getting closer to being able to travel without the annoying stops to refuel the batteries.

This incredible technological advance could have giant implications in increasing the range that an electric car can travel between charges while it is traveling on the highway, and not only this, but this new advance will also allow greater mobility of industrial plant robots, and naturally, while reducing production costs.

The group of scientists from the Stanford University, based on the research initiated by MIT, transmit enough energy in the space of 1 meter to illuminate an LED while it was moving, and although a lot of work is still needed until this technology can benefit our day-by-day and our electric vehicles, is irrefutably a giant step, as it proves that it is possible to transmit electric current to a moving object.

The idea of transferring energy through the air over long distances isn’t new, in fact it is almost as old as electricity itself, and was first presented and proven in the XIX century by our preferred inventor, Nikola Tesla, who resorted to capacitors to increase current voltage, and produced our well-known, Tesla Coils.

The principle used in the Tesla Coils, is similar to the base of another idea of his that we use every day, in our day-to-day, the electric induction motor, which transmits energy through electromagnetic force.

Although Tesla did not live to see the “wireless world” he helped create in action, without him it would never have been possible to have anything we have today, not even a simple computer.

In this case, the scientists went looking for a technology developed by an MIT research team about 10 years ago, which allowed the team at the time, to transmit 60 watts at a distance of 2 meters, with an efficiency rate of about 40 percent . The problem is that this transfer method depends on the angle of the magnetic field, which when working with a moving object is a crucial problem.

In order to overcome this situation, scientists have used a voltage amplifier and a response resistor that automatically adjust the voltage based on the data received to allow the transfer of the electric current.
