Using sunlight, lens (convex lens, fresnel lens) light concentration heat power generation

Abstract

The application discloses a theory and a method for generating electricity by using sunlight and lens (convex lens, Fresnel lens, hereinafter referred to as lens) to produce heat. The theory is that sunlight is concentrated by the lens to produce heat, and the heat is used to generate electricity by a generator or a thermoelectric effect.

Description

[0001] This invention enables humans to better utilize solar energy: by using a solar lens to concentrate sunlight and generate heat to produce electricity. Solar energy is inexhaustible, pollution-free, and considered the cleanest energy source for humankind. It can be used to generate electricity, electrolyze water to produce hydrogen, and burn hydrogen to generate electricity. This allows for a continuous current in this type of power generation, which is of great significance.

[0002] I. The specific power generation theory is as follows:

[0003] Heat generation: Sunlight is focused through a lens to generate heat. The hot spot turns the water in the tank into steam. The steam then drives the impeller on the generator, causing the generator to rotate and generate electricity. Alternatively, the steam drives a steam engine, which in turn drives the generator to generate electricity.

[0004] (See attached) Figure 1 )

[0005] Thermoelectric effect power generation:

[0006] Sunlight is concentrated by a lens to generate heat, and the hot spot shines on the hot end of the power generation module to generate electricity, or shines on the heat conductor above the hot end to generate electricity.

[0007] Thermoelectric effect: refers to the phenomenon where two different electrical conductors or semiconductors are connected at one end and heated, and a potential difference exists between the other two ends.

[0008] Two different metallic conductors or semiconductors, AC and BC, are connected at point C. Heating point C and connecting points AB generates an electric current. (See...) Figure 2 )

[0009] Connecting multiple such devices in series increases the voltage (see...) Figure 3 )

[0010] Power generation methods: Two experimental introductions (with video)

[0011] 1. Generating electricity using heat and generators

[0012] <1> Required equipment:

[0013] ① Lens with adjustable frame

[0014] ② Water tank

[0015] ③ Connect the tee

[0016] ④ Pressure reducing valve

[0017] ⑤ Air duct

[0018] ⑥ Air nozzle

[0019] ⑦ Impeller generator

[0020] ⑧ Voltage regulator

[0021] ⑨ Conductor

[0022] ⑩ LED lights

[0023] ⑪ Bracket

[0024] ⑫ Water tank lifting frame (for adjusting the height of the water tank)

[0025] <2> Operating instructions:

[0026] First, connect the impeller generator, voltage regulator, and LED lights with wires and fix them on the bracket. Fill the water tank with an appropriate amount of water and connect it to the tee. Then connect the tee to the pressure reducing valve and the air pipe. Next, place the water tank on the lifting frame. Under sunlight, adjust the lens angle by adjusting the frame nut to make the lens in the most ideal focusing state, with the focal point focused on the lower part of the water tank. This completes the basic installation of the device.

[0027] Under the heat-concentrating effect of the lens, the water quickly boils, generating steam which is then ejected from the nozzle in the air duct. The nozzle is aimed at the generator impeller, driving the generator to generate electricity, the LED lights up, and power generation is complete. (See...) Figure 1 (The video is recorded.)

[0028] 2. Thermoelectric effect power generation

[0029] <1> Required equipment

[0030] ① Lens with adjustable frame

[0031] ② Hot water box

[0032] ③Cold water box

[0033] ④ Wire

[0034] ⑤ Power generation module

[0035] ⑥ Heat sink

[0036] ⑦ Voltage regulator

[0037] ⑧ LED lights

[0038] 9. Stent

[0039] <2> Operating instructions:

[0040] First, glue the generator module and heat sink together. Connect the LED light and voltage regulator with wires. Then, place the side of the generator module with the heat sink inside an aluminum box filled with cold water. Place another aluminum box filled with cold water on the other side, which is facing upwards. Under sunlight, adjust the lens angle so that the focus is on the lower part of the aluminum box above the generator module. After a short time, the LED light will turn on, and power generation is complete. (See...) Figure 4 (A video is included.) The above describes two power generation methods, both of which utilize solar lenses to concentrate sunlight and generate heat.
