What you said is not complete enough. This is news from the Hunan Metropolitan Channel. It is a liquid that looks a bit like red water and can be drunk. Connect the positive and negative terminals of the AA battery to both ends. Electricity can be generated by connecting a light bulb or tape recorder to the front of the driver, which can generate 2,100 watts of power. I can't ask for an explanation. The original person on TV said that whoever breaks the crack will be rewarded with 100,000 yuan.
Why do water lamps light up when they touch water? How long does it last?
You've never seen it before, and it's probably difficult to popularize it, because except on very special occasions, it's convenient and cheap to have electricity .
The LED is a component that must use electricity to light up. Not using electricity means not using batteries. Where does the energy come from? It is necessary to convert other forms of energy into electrical energy to use it. The simplest and most straightforward is the fuel cell. No matter what type of energy is ultimately converted into electricity, how can it be said that it does not use electricity? !
Unless it's not an LED light source, but a non-electroluminescence involving water, that's too avant-garde, I'm looking forward to that! But "there is also a screw port that can be used for electricity" means it also has electroluminescence function. Oh my god, your friend is either ignorant or an expert.
What is an LED shower?
The touch bulb contains a battery. When the battery is exhausted, it will not turn on.
The hydraulic energy lamp is driven by the impact of water flow on the wheel, causing the rotor connected to the wheel to rotate through the bearing,then generates electromotive force in the generator coil through the principle of electromagnetic induction.
The principle is to connect the positive and negative poles of the bulb to turn on the light, or after arriving, grab all the metal parts of the lamp holder, or put the lamp holder part into the water. Cup, but the water level cannot exceed the heat dissipation hole of the lamp holder, otherwise it will enter the lamp holder. Water will cause a short circuit in the circuit and cannot be used.
Detailed information:
Hydraulic resources are one of the sources of electrical energy. When planning electrical energy, it must also be planned according to energy conditions. In regions with relatively abundant water resources, priority should be given to the development of hydropower and the maximum use of renewable energy to save coal, oil and other valuable resources.

The so-called LED shower head refers to a q shower headui adds interesting light changing effects and water saving functions on the basis of meeting people's needs. daily bathing needs. Shower heads and LED shower heads are popular high-tech electronic products today. They can freely disperse the flowing water column. Full of crystal brilliance, it transforms your shower room into a dream world. Usually, LED shower heads achieve this dreamy effect by integrating LED lights into the shower head. The power required for LEDs does not require additional electricity. generated by the water flow. Therefore, a micro-hydroelectric generator is installed inside the LED shower head and the water pressure is increased through some physical principles. Even if the water supply pressure is low, it can ensure smooth water flow and generate ain currentif. that the shower head can be used normally. The light colors emitted by LED shower heads currently on the market mainly include seven different colors: white, green, red, blue, **, purple and cyan. When water of different temperatures passes through the shower head, it emits different colors. light. LED shower heads are very popular among people because they are relatively new in design, environmentally friendly and energy efficient in use.
