Other Turbines in Comparison

Francis turbine The Francis turbine is a reaction turbine, which means that the working fluid changes pressure as it moves through the turbine, giving up its energy. A casement is needed to contain the water flow. The turbine is located between the high pressure water source and the low pressure water exit, usually at the … Read more

LOW HEAD INVOLUTE WATER TURBINE DESIGNS & PLANS

The water turbine designs pictured here are new approaches to low-head water power generation.  Thanks to the instigation of Rod Johnson and preliminary funding from Rich Gover, I designed, built and tested several concept prototypes and learned much about the involute spiral geometry and its potential for harvesting energy.  Hopefully, these efforts will receive further … Read more

VERTICAL AXIS INVOLUTE SPIRAL WIND TURBINE

REVOLUTIONARY NEW DESIGN! This design offers many advantages over a traditional Horizontal-Axis Wind Turbine (HAWT) or Vertical Axis airfoil blades: Vertical axis means it spins like a top, without having to turn into the wind, nor torquing the gyroscope and wearing out bearings. Gravity creates even blade torque rather than the huge forces of downward … Read more

BIOMASS ENERGY: THE RESOURCE

Learn here about the cleanest, most efficient furnace fueled by one of the most promising domestic alternative energy source available anywhere! About 98% of the energy used by mankind today is derived from biomass; it is solar energy stored in plants by photosynthesis. Although our most widely used fuel source is nonrenewable fossilized biomass (coal, … Read more
