..perhaps we can use water ,air , gravity and buoyancy to create self sustaining energy using the four most abundant resources air (gas),water (fluid ) gravitational pull (downward Force) and buoyancy upward force of pressure on a given volume causing an upward force using a cylinder half full (up and down ) then harness the upward and downward forces to run a air pump to fuel the buoyant force and fluid to run the downward force and generate electricity
that will in turn fuel itself and create excess for distributions does that make sense there many other forces that can be harnessed as well this is something I've been thinking about for some time but with no one to check out my concept
the device can be scaled to whatever size you need and the basic concept is that it will power itself once started and send surplus on down the line to a battery or power grid it could be used to charge battery's or something else the device could use many different (FREE) forces to power a generator gravitational,rotational,
..my first idea was to take a cylinder and put a divider down the center and fill one side with a fluid (water) and on the other side would be open to the bottom the fluid side would have a downwards facing cup and the open side a up ward facing cup and utilizing buoyancy/pressure to raise the fluid side cups running a generator and the open side would use the upward facing cups filled with water from the fluid side flowing downward exerting the downward Force
you could line the sides of the fluid side with small propellers /generators and have air bubbles flow over them creating an upwards force /FUEL all you need are high efficiency air pump and generators it could be retro fit in many differnt ways and is powered by free forces and will never run out of and would be made entirely of recycled materials and used anywhere depending on the fluid and density but making the device would be simple
