Trees blow back and forth all the time out of my window and its healthy for them to move back and forth to grow, but why can't we collect the energy of a tree moving back and forth with possibly 100s of pounds of force. Through a generator you could collect this energy of a tree moving back and forth an inch or so. Why stop at one tree when you could connect a few trees solid enough to sway together, you'll get an amazing amount of force. What is the downfall, weakness, or slippery slope. I am in the middle of drafting the idea of this massive collector of sun's energy with using so little man made materials.
