Since then, the electricity buoy has been continually developed. The serial production of the &amp; nbsp; current buoy 3 &amp; nbsp; with 250 cm rotor diameter, a nominal output of 70 kW and an estimated electricity generation 220 &#8211; 250 MWh \/ year has already been started. The potential of the electricity buoys becomes clear when one realizes that the area of the entire Wachau (about 30,000 households) of 500 electricity buoys suspended outside the shipping channel, which produce 100 GWh of electricity every year, is supplied with sufficient energy can be. Depending on the rotor diameter (150 cm, 200 cm, 250 cm), the current buoy can be used in rivers of different sizes. The rivers must have a minimum depth at low water of 200 cm, 250 cm and 300 cm respectively. In the future, larger buoys will also be produced for use in the sea. In order for the electricity buoy to be operated economically, an average flow velocity of at least 2 m \/ s and an average water flow of at least 50 m\u00b3 \/ s is necessary. But even an increase in the flow speed by 10% brings a performance increase of 30% with it.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-5cd2b0cd elementor-section-content-middle elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"5cd2b0cd\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-4d754b85\" data-id=\"4d754b85\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-5e4d1156 elementor-widget elementor-widget-image\" data-id=\"5e4d1156\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"525\" src=\"https:\/\/www.ecotechnology.at\/wp-content\/uploads\/2023\/06\/Aqua04.jpg\" class=\"attachment-large size-large wp-image-3766\" alt=\"The Power Buoy - The Floating Mini Hydropower Plant.\" srcset=\"https:\/\/www.ecotechnology.at\/wp-content\/uploads\/2023\/06\/Aqua04.jpg 700w, https:\/\/www.ecotechnology.at\/wp-content\/uploads\/2023\/06\/Aqua04-300x225.jpg 300w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t<div class=\"elementor-column elementor-col-50 elementor-top-column elementor-element elementor-element-513681d5\" data-id=\"513681d5\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-55dcb704 elementor-widget elementor-widget-text-editor\" data-id=\"55dcb704\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Depending on the rotor diameter (150 cm, 200 cm, 250 cm), the current buoy can be used in rivers of different sizes.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-5eb1704 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"5eb1704\" data-element_type=\"section\" data-e-type=\"section\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-4de9bfb\" data-id=\"4de9bfb\" data-element_type=\"column\" data-e-type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-eece67f elementor-widget elementor-widget-text-editor\" data-id=\"eece67f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>The above-mentioned conditions are, according to the investigations of Aqualibre Energieentwicklungs GmbH in Austria, from the large rivers such as the river Rhine, the river Traun, the river Enns, the river Mur, the river Drau, the river Inn, the river Salzach and the river Danube.

The current buoy is a hydroelectric turbine, which is integrated in a buoy, which is installed directly in the river (or in the sea) and produces electricity continuously. In contrast to other types of hydroelectric power stations (river and storage power plants), only the kinetic energy of the water flow in rivers or in the sea is used. Neither the ecology of the water nor the fish are threatened or the shipping is affected. Also the water quality, the river continuum as well as the whole landscape remain unchanged by the installation of the electricity buoy. In contrast to other solutions, the structural complexity is considerably lower, since no dams, dams, locks and fish ladders are required.
