PROBLEM TO BE SOLVED: To provide a wind turbine generating installation that has a simple structure and is inexpensive, and that is effective in a water channel or a river having a relatively high flow velocity and a relatively large flow volume.KIMURA MASANORI...
However, wind turbine simulation through Computational Fluid Dynamics (CFD) software offers inexpensive solutions to aerodynamic blade analysis problem. In this study, two-dimensional aerofoil (i.e. DU-93 and NREL-S809) CFD models are presented using ANSYS-FLUENT software. Using the Spalart-Allmaras...
As in all areas of the computer penetration and large-scale integrated circuitry and the gradual development of applications is being continuously toward social frontier. Because it has low power consumption, is a powerful, small, inexpensive, easy-to-use, reliability, work characteristics, and ther...
PURPOSE:To obtain an inexpensive small-sized generator having a simple structure, and a stable quality by employing a gear in which part of a gear train for transmitting a mechanical energy obtained from a rotary bobbin, is formed of a rubber material of an elastic plastic material. CONSTITUTION...
Inexpensive micro turbines on the Kaplan turbine model are manufactured for individual power production with as little as two feet of head. 4. Tubular turbineThe tubular turbine requires less space than other turbines, a saving in civil costs is realized due to a smaller p...

Safe, inexpensive batteries with high energy density are essential to transition to clean energy. Cui’s research could help combat climate change by storing wind and solar energy, reducing dependence on fossil fuels, and meeting pivotal sustainability goals. ...
There is more than enough iron, aluminum, silicon, sodium, carbon, chlorine and various other very inexpensive elements to make a real difference. It will take more than one technology to provide a good fit for each application. I thought that I said this some time ago: The carbon in ...
