How about we use GRAVITY in a different way for energy!!!!! We can use mountain sides with rail track that goes top to bottom. Have water pipes at top. Fill train cart with as much water as possible. Utilize a hard slope to assist in cart acceleration down a tall mountain. The brakes can generate emissions-free electricity while pulling up another cart from the bottom to the top (but empty) I mean if windmills can be a thing then so can using gravity as a source of energy. Hopefully this should free us to repurpose trash into bricks that we can use to house the homeless using gravity generated energy.<br><br>These options may be sub-optimal to the educated engineer, i understand that i just want to point out that we HAVE OPTIONS!!!! all we need is real unity!
