The wind is then delivered to the turbine/generators and converted into electricity. The Venturi Effect is a phenomenon that occurs when a fluid flowing through a pipe is forced through a narrow section, thereby resulting in a decrease in pressure and an increase in velocity. The wind is funneled through the system and concentrated and further accelerated in the Venturi Effect section of the system. It is shaped like a funnel with an omnidirectional intake area that allows wind collection from multiple directions. Invelox has been developed by Sheerwind, a company based in Minnesota, USA. The turbine can generate energy from wind speeds of up to 5 meters per second, delivering up to 1,500-kilowatt-hours per year, thereby enabling the supply of about a third to half the electricity of an average Dutch home.
The blade is shaped like a spiral, enabling it to swivel and collect wind energy at angles up to 60º from the central axis. The turbine features a front-facing rotor but is designed along the lines of the Archimedes screw pump which was used in Ancient Greece to pump water. It can also capture wind energy from multiple directions. It is also cheaper and more environmentally friendly.ĭutch tech firm The Archimedes has developed the Liam F1 Urban Wind Turbine for domestic use, generating as much as 80 percent energy from the wind while also being considerably quieter than conventional turbines, compact and affordable. There are no moving parts, thereby eliminating the need for lubrication and reducing wear and tear. The new turbine captures this energy via a fixed mast, power generator, and a hollow, lightweight cylinder.
The turbine uses the energy of vorticity in which wind bypasses a fixed structure, generating a cyclical pattern of vortices which then causes the structure to oscillate.
