ABSTRACT:

BACKGROUND
A turbine is an element which moves based on fluid flow. Conventional turbines use a rotational element, which is rotated by the flow. For example, a gas turbine in an electrical power plant is caused to rotate based on expanded exhaust gas from a combustion chamber. Aircraft jet engines are another form of turbine which rotate to move gas and cause thrust from the moving gases.
Conventional turbines use a set of vanes arranged around the periphery of one or more rotatable disk. Using the example of a turbine arranged as a generator, fluid movement through the vanes rotates the disk and converts at least some of the energy in the fluid flow into rotational energy of the disk.
On the scale of a typical turbine, that is the macro scale, conventional rotating turbines work well. However, when a turbine is miniaturized below a certain minimal size, it becomes difficult to form rotating bearings.
SUMMARY
The present application teaches a system which uses an oscillating moving turbine. The oscillating turbine is displaceable from its reference position, and also can be restrained by a restraining mechanism. The restraining mechanism can be a flexural structural element.
The turbine can be connected to a motive element, e.g., a driven element such as an electrical power generation element, or to a fluid flow generating element, such as an engine.
