Answer to Question 1

This is true, especially of magnesium and, to a lesser extent, chlorine.

Answer to Question 2

The surface of the ocean is in constant motion. Even if many wave energy
machines are operating and reducing waves locally as the energy is absorbed by the devices,
there is little chance that it would greatly affect climate or weather. There is some possibility
of collision of mammals (porpoises, whales, sea otters, sea lions, etc.) with the devices (fish
should not in general be affected). It is impossible to say there will be no adverse effects,
but the disadvantages are small.
