An experiment with a dynanometer has shown that the pressure exerted by
the sea waves during a storm often exceeds 7,600 pounds per square
foot. Multiply this by 1,393,920,000,000,000 feet, which the surface of
the ocean presents, and we gather some little notion of the
inconceivable power that is running to waste. When will come the
inventor who will harness the sea and set it to lighting our cities and
carrying men and mail-bags? There is said to be millions upon millions
of gold strewn on the ocean’s bed as the result of wrecks, but there is
vastly more gold for the daring inventor in the waves that forever pound
upon the beach.
