The Quasiturbine operates based on a novel design that aims to provide high efficiency, reduced emissions, and improved power output compared to conventional piston engines.

A radial piston pump is a type of positive displacement pump that features pistons arranged radially around a central axis or cylinder. In this design, the pistons move in and out of their cylinders in a radial fashion, which allows for efficient fluid transfer. Radial piston pumps are often used in hydraulic systems where high pressures and precise control are required.

A reciprocating pump is a type of positive displacement pump that uses a back-and-forth (reciprocating) motion to move fluid. This motion is typically achieved using a piston, diaphragm, or plunger that moves within a cylinder. The fundamental operation of a reciprocating pump involves the following key components: 1. **Piston/Plunger/Diaphragm**: The reciprocating element that moves back and forth to draw in and expel fluid.

A rope pump is a simple and effective type of water lifting device used primarily in rural and less developed areas for extracting water from wells or other sources. It consists of a long, flexible rope with a series of cups or containers attached to it. The rope is looped around a cylindrical casing or a pulley system, allowing it to rotate. When the rope is turned, the cups lift water up from the source and discharge it at the top.

A rotary compression pump is a type of positive displacement pump that uses rotary motion to compress fluids, primarily gases. These pumps typically consist of one or more rotating elements, such as rotors or screws, that move the gas through the pump mechanism. As the gas moves through the pump, the volume decreases, leading to an increase in pressure. **Key Characteristics of Rotary Compression Pumps:** 1.

A rotary vane pump is a type of positive displacement pump that utilizes a rotating mechanism to move fluids. This pump consists of a rotor with multiple vanes (blades) that slide in and out of slots as the rotor turns. The design allows the pump to create a vacuum or generate pressure, which enables it to transfer fluids efficiently. ### Key Features of Rotary Vane Pumps: 1. **Construction**: The pump typically has a cylindrical housing within which the rotor is positioned.

A rotodynamic pump, often referred to as a centrifugal pump, is a type of dynamic pump that utilizes rotational energy to move fluid. The core principle behind rotodynamic pumps is the conversion of mechanical energy from a rotating impeller into kinetic energy in the fluid, which is then converted into pressure energy. ### Key Features of Rotodynamic Pumps: 1. **Impeller**: The primary component that imparts kinetic energy to the fluid.

The Roundabout PlayPump is an innovative device designed to provide both recreational play and access to clean drinking water in communities, particularly in rural areas of developing countries. It combines a merry-go-round with a water pump, allowing children to play on the equipment while simultaneously generating water for community use. When children spin the Roundabout, the mechanical energy generated from the motion is converted into pumping water from a borehole or well into a storage tank, making it accessible for drinking and sanitation purposes.
