  • Model Wave Power Machine
  • This Machine could be used to compress air, to drive an Air Engine, or to work the Electric Light at any Light House, or for other purposes on the sea coast. No difference would be made in the forward motion by the irregularity of the waves. With a cylinder 20-ft. in diameter and 18-ft. wave per minute, the machine would be equal to 19 horse power, and with 3 waves per minute, each 5-ft. it would give 22 horse power. It has been favourably reviewed in "The English Mechanic and World of Science" of October 22nd, 1875.
