An Austrian engineer, Franz Zotlöterer, has developed a new method for small scale hydropower by creating a whirlpool that avoids many of the problems typically associated with hydroelectric generation.
In terms of http://www.jubileecampaign.nl/cialis-mail-order green power generation, solar and buy viagra no prescription wind get much of the attention. Hydropower is as green as wind and solar in terms of limiting emissions, but some of the ecosystem disruption associated with large-scale hydro have taken it off the table as a choice for good green power. However, smaller scale hydropower options can provide electrical power and provide additional benefits to the waterway.
The original idea behind the vortex was, in fact, not power generation, but water purification. A vortex in the water serves to efficiently aerate the recommended site how to buy cialis water and to aid in more rapid breakdown of contaminants.
The idea to look there buy real levitra online without prescription use a continuous, strong vortex flow actually occurred to Franz Zotlöterer while trying to solve the inherent problems with water quality of the natural swimming pond he had set up in his own garden. He finally decided to build a small rotation basin to aerate the water – and it worked. He then began to think about other potential fields of application for his aeration concept: drinking water supply, wastewater treatment, electricity generation. - Aquamedia
Instead of channeling the water directly through a turbine, vortex hydropower creates a spinning vortex, and draws energy from the swirling water. This approach makes it possible to generate energy without completely blocking the waterway and eliminates the need for much screening or filtration. Small debris is not a problem for vortex generation as it would be for a conventional turbine. Furthermore, fish are able to tramadol cod 180 pass by the vortex chamber without harm. The vortex operates at slower speeds, and the www.boehler.org large open chamber makes it possible for fish to pass even going upstream. The vortex also reduces the temperature change of viagra discount drug the water, and can more readily be integrated into the natural river environment.
The pilot plant only needs a fall of 1.3 meters (4.25 feet) and, with a flow rate of 1 cubic meter per second (about 265 gallons per second), produces 8 kW of electricity, enough for about 14 average European homes. A head of as little as 0.7 meters (2.25 feet) is possible for a vortex generator. The much lower rise makes it easier to locate a vortex generator on a smaller waterway, without the need for high dams and other interventions typically associated with hydropower.
The vortex system is about 80% efficient, comparable to a standard turbine. However, the vortex cannot scale as large as a turbine power plant. A vortex has a range of performance up to about 150 kW, while a traditional turbine can reach up to 100 MW.
A system that both generates electricity and helps to clean and we recommend levitra price purify the water is a great technology of the kind we like to see.
Thanks for the tip, VikingHouse
