Harnessing the power of the ocean - Curious

To maximise the power drawn from tides, a tidal turbine should be placed where the tidal flows are fastest, ideally reaching more than 10 km/h, although slower flows can be used. These locations are often where the flow has been concentrated between obstacles, such as between islands or rocky outcrops, or at the entrance to a bay or river.

Wind Turbine Efficiency - DataGenetics

The velocity of the air flowing through the turbine disk is the average of the upstream and downstream velocities. If we calculate the power of the air upstream, and subtract the power of air downstream, the difference is the power extracted by the turbine. We know the power is the half the mass flow rate times the velocity squared.

Sulfur dioxide, SO2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) that contain sulfur. Sulfur dioxide dissolves easily in water to form sulfuric acid. Sulfuric acid is a major component of acid rain.

If air velocity were increased further, the bed material would be blown away.
