Yesterday, it was learned that a student of Wuhan University who used leaf power generation has won the first prize in the 7th National College Student Energy Conservation and Emission Reduction Social Practice and Technology Competition sponsored by the Higher Education Department of the Ministry of Education: If every tree tree is loaded with them The device can basically be uneasy street lights, and the big trees can realize the night illumination at night.
The creative name is “Green Plant Transpiration Power Generationâ€. Team member, Wu Dao Power and Machinery College 2011 undergraduate student Shan Yuanhong told reporters that they are using the "natural" transpiration of green plants. Tree transpiration can provide very large energy. It is a green treasure. Because transpiration can utilize solar energy in the environment, low heat energy and breeze energy that are difficult to collect, the advantage of this power generation method is that it can collect these very weak energy for the benefit of mankind. .
At the experimental site, they put a beaker in place. The electrolyte solution in the cup simulates the inorganic salt solution in the soil, connects the twigs to the power generation device, and puts it in the beaker solution to simulate the large tree to absorb the inorganic into the ground. The process of salt solution. In order to show the power generation effect, the other end of the device is a circuit board, which is a smiley face that the students use 5 diodes to spell out. In a short while, the "smiley face" on the board will light up.
The students introduced that because of transpiration, the twigs will “suck†the solution and flow through the power generation device. The core of the device is a nanometer film with a thickness of 26 mm and a micron level, and the principle of the power generation device flows through the nanometer through the electrolyte solution. The membrane generates electrical energy, and then the electrical energy generated by the electrodes coated on the nanofilm is transported out.
Their initial idea was to design a "tree light" in combination with existing LED technology. "If you let the device work for a day, the energy accumulated by a tree all day, you can supply an LED light at night. If the street lights are directly powered by trees at night, you can save a lot of resources!"
