Principle: Inject compressed air from the lower side of a submerged buoyancy turbine ▶ Rotate the turbine by buoyancy

Air flows into multiple baskets on one side of the water turbine

One-way shaft rotation due to the buoyancy of the air filling the basket on one side
Turn over and air discharge of raised buoyancy chamber

Maximize rotational speed (RPM)
Various water purification effects

Water flow generation effect / Effect of underwater oxygen supply / Mixing effect of water surface and bottom water Prevent stratification caused by water temperature / Prevents freezing of water during winter Reduce, prevent, and block access to green algae
