Abstract: To solve the problem that a charging installation is essential for an EV, a LiB is heavy and a high cost, and its life is short due to a chemical battery, and it contains a heavy metal, and the EV is said as a pollution-free, but a lot of commercial power supplies is from a power of a hydrocarbon fuel.SOLUTION: The problem can be solved by performing an in-house power generation by a RFG in an EV vehicle. When a power is produced by oneself and consumed by oneself not only by being applied to the EV but also by installing a RFG+LiB to a general home and a business office, a problem on a blackout can be solved. On the earth, there are a pollution-free and unlimited energy, a gravity, and a magnetic force. Regarding to the gravity, a power is fetched out as a water force. The present invention is to fetch a power of a high voltage from a permanent magnet by using a natural law as a magnetic force of the permanent magnet, an electromagnetic induction, and a three-phase current. A generated power of the water force is calculated by a formula of 9.8×an effective head×water amount (m3/sec) ×a total efficiency. There is a formula of a construction factor having the maximum energy product (BH)max of the permanent magnet, a winding length, the number of poles, a speed (rpm) of a rotator, the total efficiency for the generation power of the magnetic force.SELECTED DRAWING: None
