In the future, electric cars could recharge on their own while a driver drives. In addition, this can be done wirelessly, making it easier to drive hundreds (or even thousands) of miles without having to plug it in. Over the last two years, Khurram Afridi and his colleagues have developed evidence of the concept for wireless power transfer that transfers electrical energy through electric fields at very high frequencies. The ability to send large amounts of energy across greater distances could one day allow the technology to begin powering bigger things like automobiles. The challenge of using electric fields for wireless power transfer is that the large air gap between the roadway and the electric vehicle results in a very small capacitance through which the energy must be transferred. These scientists continue to research and eventually find the solution.

This relates to engineering because it involves conducting research and then finding a way to construct using that knowledge.
