Discussed is a wireless charging device that changes a direction of a magnetic field generated by a transmission coil, through a repeater capable of rotating in a plane, and supports a user terminal in parallel with the repeater, to wirelessly transmit power in various directions and at various angles. The wireless charging device includes a power transmitting module including a plurality of transmission coils arranged side by side, therein, a terminal supporting module including a repeater therein and disposed at a slant with respect to an upper surface of the power transmitting module on the upper surface of the power transmitting module, a moving module to move the terminal supporting module along a direction in which the transmission coils are arranged, and a controller to supply a voltage to any one of the plurality of transmission coils depending on a position of the moving module.

A magnetic alignment system can include a primary annular magnetic alignment component and a secondary annular magnetic alignment component. The primary alignment component can include an inner annular region having a first magnetic orientation, an outer annular region having a second magnetic orientation opposite to the first magnetic orientation, and a non-magnetized central annular region disposed between the primary inner annular region and the primary outer annular region. The secondary alignment component can have a magnetic orientation with a radial component.

A power receiving device is disposed underwater. The power receiving device includes a housing formed of a weak magnetic material, a ferromagnetic body that surrounds an outer side of the housing and is formed of a ferromagnetic material, and a power receiving coil wound around an outer side of the ferromagnetic body.

Solar radiation is collected and converted to microwave energy by means maintained in outer space on one or more platforms in space. The microwave energy is then transmitted to earth and directed to and constantly focused on one or more segments of a generally circular and slowly rotating tropical depression, which is a precursor to a tropical storm and then a hurricane (alternatively called a cyclone or typhoon). The focused microwave energy interrupts the cycle of vertical upward and downward movement of air, water, & water vapor, and destabilizes the developing rotational motion of the tropical depression, causing it to break up and dissipate, and preventing it from ultimately developing into a hurricane. When not focusing microwave energy on a tropical depression, the microwave energy can alternatively be used to create earth based solar energy, which would help alleviate costs of operating the system solely for hurricane prevention.
