Synergy of naturally renewable energy sources and gravity for clean energy production and environmentally friendly energy storage

The number of inventions concern a producing electric energy from renewable energy, characterised in that the following integrated operations, all functioning in synergy, are carried out: capturing renewable energy; using this renewable energy for compressing a gas(free air); storing this cold-pressed gas in underwater ballons; then reclaiming it (by natural gravity water pressure) in controlled manner; converting the energy derived from this reclaiming into mechanical energy by means of a mechanical device; converting said produced mechanical energy into electric energy. The inventions concern the number of high efficient devices:

1. Hydro kinetic energy machines
2. Solar energy machines
3. Wind energy machines
4. Gravity-boosted hydro-kinetic machines
5. Underwater elastic balloons with compressed air inflation (energy storage) and return of the compressed air from the natural gravitational pressure of the water
