free energy (almost)

wood powered air compressor 15 to 20 feet high, have not added the valves or pistons or gears but i thought this idea up today and felt like sharing it, last month I posted an idea about using steam pressure to pump water vertically and with the right configuration a header tank might be able to be adapted to work this contraption, using kinetic energy with a spring on the main arm and the weight of water to operate the arm to drive pumps. I dislike seeing fires go to waste and theres only so much damper you can cook. its the first time ive attempted to upload a movie, hope it works otherwise this message is pointless.
