Show HN: Will this buoyancy perpetual motion engine work?
Please feel free to dismantle this weird idea or if you think you can improve on this design. Please go-ahead and improve on it.
The idea is based on principles of buoyancy and electro-mechanical cylinder (though there is no DC motor is been used, instead there are spring coils to which keys are given just like what clocks have)
Please explain the flaws and why it will not work?
