Tree power?

Scientists have known for a long time that plants have the ability to conduct electricity. This has been proven before with the potato or lemon experiment. Power through trees is different though. The scientists use the same metals for both electrodes, while the potato and lemon conductivity test use two different metals. The Big Leaf Maple tree is the best tree for obtaining energy. It generates a steady voltage of about 200 millivolts. This is obviously not enough volts to power anything, but scientists have created a way to store this small amount of energy. When energy is stored you can add to it, until the energy level is high enough to power something. This way of obtaining energy is not as practical as most, but it is just another green form of energy we have now. You can never have too many environmentally safe energy sources. Any cut back on harmful sources of energy is helpful, and that’s not all it can be helpful for. Scientist can use the electrical output to keep track of the trees health. The more healthy trees we have the more oxygen we have. And, if we stop or slow our pollutant emissions the healthy trees will delude the harmfully toxins in the air. This is a source of green energy and is beneficial to the trees.
