## Systems of wireless electric supply

There are some systems of wireless electric supply.- The system of electric wave aims at space-based solar power.
- The system of an electromagnetic induction is the power transmission which is using electromagnetic induction.
- The system of a magnetic field resonance is a system which Massachusetts Institute of Technology announced.

However, each has the strong point and demerit.

Therefore, it is impossible to make one system apply to anything and to employ it.

Let's consider each system!
