"Tree lights" instead of street lights? Wuhan university students fun LED

On 19 July, a creative power leaves using Wuhan University students, the Ministry of education sponsored by the College of the seventh national energy saving and emission reduction of social practice and science and technology competition won the first prize: if the trees are installed on their devices, the basic can be unsettling tree lights, can realize the whole night lighting in the night.

The idea of "green plant transpiration power generation". Team members, large power and mechanical engineering 2011 undergraduate Dan Yuanhong told reporters that they use the green plants "nature" transpiration. Trees transpiration can provide very large energy, is a green treasure, because transpiration can use in the environment, it is difficult to collect the solar heat energy, the power of breeze, the advantage is that you can collect the weak energy, for the benefit of mankind.

See in the scene, they put a glass beaker, electrolyte solution is simulated inorganic salt solution in the soil, small branches and power generation device connected to the solution in the beaker, simulation trees to the underground drawing process of inorganic salt solution. In order to demonstrate the effect of power generation, the device is a circuit board on the other side, the above is the students with 5 diodes spell a smiley face. In a short while, the "smile" on the circuit board.

Students, because of transpiration, small branches will be "sucked" dynamic solution, through the power generation device, the device is a 26mm nano film core diameter, micron level thickness, and the principle is through the power generation device of electrolyte solution through directional nano membrane to produce electricity, Seoul by nano film under plating the electrode will generate electricity.

Their initial idea is to combine the existing LED technology, the design of a "tree lamp". "If the device works for a day, the energy accumulated by a tree all day long, to the night can supply a LED lamp lighting, if the night lights are powered directly by the tree, you can save a lot of resources!
