The Linear Motion Translating Wing / Shuttle Foil (TW/SF) process is based on the use of the common air or hydrofoil.
The common sail is a form of airfoil, similar in function to an aircraft’s wings.
This ultra simple process was first created 100s of millions of years ago by Mother Nature, both fish and birds, employ forms of hydro/airfoils to swim/fly.
Mankind was a relative latecomer in the use of foils. Man’s experimentation with ‘foils’ started circa 5,000 years ago, (some believe it was even earlier) with the advent of mounting a simple sail on a boat. The simple sail is in fact the oldest form of energy harvesting known to man – and by far, the cheapest.
Simple ‘Windmills’ have served man for almost 2,000 years, they also rely on the use of ‘airfoils’ to work. Ultra modern versions of these very old ‘rotary motion’ driven airfoils, a.k.a. Horizontal Axis Wind Turbines (HAWT) have replaced ‘windmills’ of antiquity, however, it is import to note that they still rely on the (exact) same principle of extracting kinetic energy from the passing wind via their ‘rotary motion wings’.
Foils, air or hydro, have been applied in many different applications. It may surprised the reader to hear that turbine engines, whether on aircraft or in natural gas generation systems, employ small airfoils internally, without them they could not function. Also, that every powerboat/ship also employs at least one hydrofoil, namely in the form of a rudder. Modern sailboats, large or small, employ both airfoils, in the form of sails, and hydrofoils, in the form of a keel and a rudder.
Whether on a child’s toy sailboat or on a mega sailing yacht, the simple sail works on all scales.
What no one can seem to tell us, is why a ‘Linear Motion’ sails (airfoils) have never before even been considered/research as a means of harvesting kinetic energy to make electricity from; literally, this appears to remain a mystery to all scientists we contacted.
The logic (and obviousness) of adding a simple cable loop to something like a working Reaction ferry, so as to have its ‘shuttle action’ pull on a wire-rope loop, to in turn, turn shore-located/situated generators, is both overwhelming and compelling, at least to us!
