Description

Technical Field

[0001] The invention relates to an energy storage device. Background Art

[0002] Assume that there is an ideal rotor whose mass is evenly distributed over the circumference of the rotor. Assume that its diameter d = 20m, mass m = 200t, and speed n = 2 rpm, then the kinetic energy it contains is W = 1 / 2mv 2 =1 / 2*2*10 ^5 *(2*20*Π) 2 =1.58*10 9 J.

[0003] From the above formula, we know that the kinetic energy of the rotor is proportional to the rotor mass, proportional to the square of the rotor speed, and proportional to the square of the rotor diameter. These three quantities can be changed according to actual needs to meet the requirements. The energy stored in this energy storage device can reach 1*10 10 Joules or more.

[0004] The attraction of two permanent strong magnet cylinders with a diameter of 1.5 cm exceeds 5 kg. Similarly, their repulsion also exceeds 5 kg, and their area is 1.77 cm 2 It can be seen that the repulsive force of the strong magnet per square meter is (10000 / 1.77)*5=28250kg. Theoretically, a strong magnet of 8 square meters can hold up a 200-ton rotor. If the area of ​​the strong magnet is large enough, the rotor will be in a suspended state. Therefore, this device can be used as an ideal energy storage device. Summary of the invention
