Wave Energy Propeller Engine
Wave Energy Driven Ship
The present device concerns an engine of Navigation. Navigating on a sea, lake, ocean or any water surface shaken by waves, undulations, streams, etc.
The device according to the invention, aims at supplying a means of
Navigation appropriate (clean), easy to use; it can be an additional means of navigation.
The device according to this invention allows navigation. By converting the kinetic energy of movements, the oscillations, right-left an/or front-back or high /down to a uni-directional one-way horizontal push. These energies are free, renewable but still undeveloped yet in navigations . They have an uncomfortable incidence. (sea sickness)
This device doing the conversion, a part of the oscillations. (Friction, Vertical Level variations), to a (one-way) horizontal push.
In fact, any variation of the boat level is attenuated and converted to a one-way horizontal push. This device converting the bi-directional kinetic energy (up/down),or any variation immerged /emerged area to a horizontal kinetic energy (one-way) push .
A similar device has been successfully used in aviation for a century, but in opposite applications. Aircraft manufacturers, the power developed by the engines and reactors pushes the air-plane forward. The arrangement of the wings ,flaps and the position of the ailerons, convert part of this power into a vertical push . Gliders also convert the current of the ascending air(sight) and or while losing of height to a uni-directional horizontal push .
This device has been experimented on a prototype (at a reduced scale) and it works perfectly. We can do a demonstration.
Navigating waves energy propeller engine . ( a model set video available)
Wave is the most abundant source of renewable energy in the world. The usefulness of available wave energy has no longer to be proved. The average the most economical, the most profitable and the most practical is to use this energy on the spot that mean on board of a vessel, ship, boat, platform or any floating element which needs to move on the ocean or sea, without any need of transforming, transporting and/or stocking.
The energy converting device uses the principle of an oscillating (frequency different) Boat / Water. This device converts the bi-directional (up/down )of the Boat's (kinetic energy ) to a uni-directional horizontal power push
Because Navigating with wave energy needs ,requires no access roads, infrastructure .
Wave energy devices are quieter and much less visually obtrusive than wind devices, which typically energy devices can be integrated in Boat producing power to travel exactly where it is needed;
When constructed with materials developed for use on Boat, Ship, Vessel, ocean wave power navigating devices (which contain few moving parts) should cost less to construction and maintain than... ( photos& video clip on request) ..
This has been tried many times. It is such a simple idea I would not be surprised to find that a "self rowing galley" was tried by the Greeks.
First check your scaling. For this thing to work a 1 meter long model has to move with 0.5 cm waves. That is tough.
The problem is energy density. You are basically driving the ship by letting the waves move a float up and down and converting that into propeller rotation. The power available is proportional to the volume of the float times the wave height. You can work out the math ( I do not care enough anymore) but you need a float at least half the volume of your ship. There are also limits on how far apart the wave peaks can be.
There have been a couple of these things that have actually worked, sorta. One was a multi segmented barge. The barge was the float. The segments moving relative to each other drove the prop. It was said to move under it's on power but it was not very strong and broke apart in calm water. The other was a boat with what looked like giant caterpillars on each side. Actually moved but it would not turn, it just stopped.
Anouther problem is wave direction. (Think wind direction) they barely go "upwave" and there is no power going parallel to the waves.
This is about all I remember. The information is from chapter in the very back of a text book, I used. The title was "problems with perpetual motion machines".
