||PCT/GB2013/050901||VERA, Eudes||VERA, Eudes|
The Accelerated Fluid Machine is an apparatus capable of generating inexpensively renewable and clean mechanical and/or electrical energy for powering partly or totally a vehicle, or a location (home, building, factory, etc.). Therefore it is an economical and effective way to reduce nowadays global warming and high energy costs. Its main components are a fluid-acceleration chamber and exhaust, and one or more fans placed inside it. It is an aerodynamic device whose operation is based upon the same physical principle of airplane flight. The generated energy comes from a fluid flow that can be created by one or more fans or captured from the environment into the chamber where it is accelerated. The machine produces no pollution, and requires no fuel at all as it is driven entirely by the fluid (typically air or water). It can be stationary, or mobile if carried by a vehicle.
