Tablespoon pico-Hydro Turbine

A Low-Cost Pico-Hydro Turbine Made with Tablespoons  

 

Millions of off-grid homes in remote areas around the world have access to pico-hydro (5 kW or less) resources that are undeveloped due to prohibitive installed costs ($/kW). The Turgo turbine, a hydroelectric impulse turbine generally suited for medium to high head applications, has gained renewed attention in research due to its potential applicability to such sites.

The research of MAE graduate student Kyle Gaiser and his faculty advisors (Profs. Stroeve, ChEMS, Erickson, MAE, and Delplanque, MAE) focuses on developing such a turbine. A low-cost, Turgo turbine made from tablespoons and readily available materials was designed, built, and characterized. This turbine reached a maximum power of 1.5 kW and a 62% efficiency.

The outcome of this investigation is a set of standardized equations to optimize the most important design parameters of a Turgo turbine. Hence this work enables the custom design and local manufacture of low-cost efficient Turgo turbines. In addition, the results can be expressed in terms of dimensionless parameters, which allow for scaling to systems larger than 5 kW.
