Dear friends. I can sense the imagination and excitement whirring up a lot but before you all tale the dip let me play the spoilsport. Let me tell you a few things that you must not venture into as that will lead to ultimate failure.
- Free energy is not possible. It goes against the very constituent of law of conservation of energy. So free energy is not possible.
- Energy harvesting from gravitational waves though not impossible is very close to it since the energy is unimaginatively small and difficult to detect let alone harness.
- The bright spot is if you can take things high up and couple it with a flywheel and let the object come down with gravity you may as well be able to harness the energy of gravitational force through the flywheel rotation.
