The Hydro Multiaxis Turbosystem (Hydromat) is a tower structure comprising large lattice like tower sections with many smaller blades that are connected to each axis or shaft of the unit comprised of many shafts with gearboxes and generators. Unlike the Multiaxis Turbosystem, the wind version of the Hydromat, water has 800 times more density and power for any given same velocity for both air and water. The use of stainless steel or any number of composites to support the powerful water velocity could be used as material and still be cost competitive, Mass Megawatts argues.
The tower structure supports the shafts as a whole. The new product was developed to simplify the blades cost by reducing their size by avoiding larger blades, which can require an expensive construction cost. Mass Megawatts maintains that using many smaller blades is a more cost-effective approach than using a large and complex one toward a given power generation unit. The Hydromat has a different approach of positioning the blades for gathering the mechanical power and directing it toward the generator for producing electricity.
