Abstract: Abstract: This article is presenting a new approach using turbines to collect energy from the different movements occurring in any direction in the oceans or rivers, as opposed to existing solutions that are focusing on specific direction of flow as the In-and-out movement of the waves. In fact, this new architecture does extract energy from randomly-agitated fluid regardless of flow direction. It is using well-known and proven technologies to create a new energy extraction process from the ocean, with low implementation, production and maintenance costs compared to existing solutions. The new proposed architecture is highly scale-able with plant's power output from few Kilowatts to megawatts range. Also, this process can be implemented in different parts of the world with almost no impact on the surrounding environment and would represent a long-lasting sustainable source of clean and cheap energy for our economies. Introduction: In the recent decades, Horizontal-axle Wind-turbines became a proven technology for producing clean energy, and are almost as competitive as other more conventional means of production. They are used in specific areas with optimal wind presence across the year, thus limiting their use. Some other types of wind-turbines with a vertical axle are well adapted in other areas with low and irregular wind speed and direction. In fact, the primary advantages of vertical-axis wind-turbines are that they are not affected by the change in the wind direction and can start rotating at low wind speed. In this novel process, we will be implementing vertical-axle turbines that are installed on the ocean's floor or mounted under floating platforms, to collect energy from the perpetual and random movement of water in the oceans and some rivers. This is a new and unprecedented way of using vertical-axle turbines to collect under-water energy, and therefore the author of this article is claiming intellectual property for such novelty. The process: Under-Water Vertical-Axle Turbines or UWVATs can be installed on ocean's floor or mounted on floating platforms, in such a way that the rotating shaft can be accessed mechanically from the surface of water to drive generators installed on a platform, well protected from salty water and weather conditions. The floating-platform configuration requires also that it should be attached to ocean's floor with cables to avoid moving with the currents. Many designs for vertical turbines do exit, and all can be used depending on their cost-effectiveness. The main point is that they collect energy from fluid movement flowing in any direction, and they will always rotate in a predefined sens, clockwise or counter-clockwise. In this article, we will use 3 half-cylindre shaped blades mounted on a rotating shaft at 1200 angle as shown on Figurel (Top view). This design has the advantage of being easy to manufacture and duplicate. On Figure I, one example is presented for the flow direction of the fluid as being perpendicular to the shaft and coming from south, which makes the 2 turbines to rotate in different directions as per the
