The Schneider HydroBeaver is a revolutionary idea in Hydro-Power Generation. Conventional dams employ the use of turbines which require a large head to generate the power. The large head is developed through dams, which alter the natural course of rivers, destroying fertile river valleys and ruining the environment for fish. The HydroBeaver plans to develop power through a head of only 3 meters. No dam is required to develop this head. The HydroBeaver unit is small and environmentally friendly. Because no dam is required, no land is destroyed, plus the design allows for safe passage of fish downstream. The purpose of this thesis was an investigation into Llie feasibility and efficiency of a linear generation unit rather than a rotational generation unit. As is, the Hydro Beaver generates power through a rotational power generation unit placed on one of the axis. The idea is that a linear generation unit would be able to provide more power, more efficiently and in less space. This thesis discovered the governing variables in a linear power generator and briefly describes how to design a linear generator according to these variables. Airgap, magnet size, magnet flux density and field intensity, as well as velocity were discovered to effect power generation. Given the size restraints of the HydroBeaver and limits on foil velocity, it was discovered that a linear power generation unit is an inefficient and not very economic approach to the power generation problem. It will develop power, but only at about 10% of the power desired. This thesis lays the groundwork on the design of a linear generator so in the event of advancement in magneto-solid technology or some other technological advance, this thesis can be referenced or reinvestigated.
