Such machines might fly at altitudes comparable to the height of the Empire State Building in New York.<\/span><\/p>\n<p><span>Isensee says the kites will have an operating window comparable to traditional turbines and could fly in outdoor wind speeds between roughly 5 m\/s and 25 m\/s. Sensors onboard detect excessive winds and can trigger the automatic reeling in of the kite, so that it returns to the ground. The team is testing some cameras and sensors that could detect birds and avoid potential bird strikes, Isensee adds.<\/span><\/p>\n<p><span>Using a kite to catch the wind is an interesting idea, says Richard Cochrane at the University of Exeter, who sometimes consults for the wind energy industry. \u201cIt could enable deployment of wind [energy <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/technology\/\" data-internallinksmanager029f6b8e52c=\"4\" title=\"Technology\" target=\"_blank\" rel=\"noopener\">technology<\/a>] on perhaps an island that you couldn\u2019t get a normal turbine onto,\u201d he adds. Isensee confirms that the system uses roughly 90% less material than conventional wind turbines and so shipping the kites to hard-to-reach or remote locations would in principle be much easier.<\/span><\/p>\n<p><span>This year, Kitekraft aims to continue its test flights and is targeting its first commercial installations around 2028.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"No_diesel_required\"><\/span><span>No diesel required<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span>Separately, an Iceland-based firm has come up with a small, vertical axis wind turbine that could power telecommunications towers and other relatively remote infrastructure. Icewind\u2019s device is a sort of open, curved cylinder spinning within a metal frame. \u201cIt\u2019s roughly the size of a refrigerator,\u201d says Stephen Drake, chief executive.<\/span><\/p>\n<p><span>The firm, which has three full-time employees and has raised $4 million to date, has used high-torque generators in these turbines, which means they rotate rather slowly. One device can output around 600 watts in winds of 10 metres per second, which is not a huge amount of power, but several sited and chained together could power a phone mast, says Drake.<\/span><\/p>\n<figure class=\"post-image post-mediaBleed alignnone\"><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-1396624 js-lazy\" alt=\"\" width=\"1536\" height=\"2048\" sizes=\"auto, (max-width: 1536px) 100vw, 1536px\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19.png\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19.png 1536w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-158x210.png 158w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-101x135.png 101w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-203x270.png 203w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-1152x1536.png 1152w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-796x1061.png 796w\"\/><noscript><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-1396624\" src=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19.png\" alt=\"\" width=\"1536\" height=\"2048\" srcset=\"https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19.png 1536w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-158x210.png 158w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-101x135.png 101w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-203x270.png 203w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-1152x1536.png 1152w, https:\/\/cdn0.tnwcdn.com\/wp-content\/blogs.dir\/1\/files\/2023\/05\/RW500_19_10_19-796x1061.png 796w\"\/><\/noscript><\/figure>\n<p><a rel=\"nofollow noopener\" target=\"_blank\" href=\"https:\/\/blog.powerbox.com.au\/why-more-telcos-are-switching-from-diesel-power\"><span>Around a million telecoms towers<\/span><\/a><span> around the world are located in areas with poor or no electricity grid connections. Thus, they currently rely on diesel generators for power. Now the telecoms industry is searching for cleaner alternatives that could include turbines such as Icewind\u2019s. \u201cWe knew it was an instant fit,\u201d says Drake. Each turbine costs around $8,000 at present and the firm plans to deliver its first commercial devices to customers this year.<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"Back_to_the_roots\"><\/span><span>Back to the roots<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span>New technologies could even change how conventional, supersized three-bladed turbines are constructed. These machines, especially those positioned offshore, are reaching gargantuan proportions, with the tallest standing nearly 300m tall at the nacelle \u2013 the point where the three blades meet. The impressive height is advantageous given that winds tend to be stronger at greater altitudes, which increases electricity production.<\/span><\/p>\n<p><span>The proportions of these behemoths create a problem, however, because the turbine towers are increasingly difficult to construct and transport. They are also very heavy. Traditional tower materials require special reinforcement for the largest turbines.\u00a0<\/span><\/p>\n<p><span>\u201cThe weight of the structure itself becomes an issue,\u201d says Otto Lundman, co-founder and chief executive of Modvion. His firm has developed a way of making turbine towers out of a completely different material: wood. Specifically, laminated veneer lumber.<\/span><\/p>\n<p><span>\u201cIt\u2019s kind of like large-scale plywood,\u201d says Lundman. These layers of wood glued together are robust despite also being relatively light in weight, allowing for the construction of towers that are about 30% lighter than traditional versions. Modvion\u2019s <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/download-scripts-themes-apps\/\" data-internallinksmanager029f6b8e52c=\"9\" title=\"Download Scripts &amp; Themes &amp; Apps\" target=\"_blank\" rel=\"noopener\">app<\/a>roach is to build modular towers in the form of circular sections, which can be shipped easily and then stacked on top of one another on site.<\/span><\/p>\n<p><span>The company has 34 employees and has netted funding of SEK210 million (\u20ac18.8 million) to date.<\/span><\/p>\n<p><span>There is huge demand in the wind energy market for materials that could enable the construction of even bigger turbines, notes Cochrane: \u201c<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">General<\/a>ly, that is the way the industry has gone.\u201d Wood-based modular approaches are primed to further the industry\u2019s ambitions, he suggests.<\/span><\/p>\n<p><span>While wood is in principle a carbon sink, the sustainability of this ancient building material and the biodiversity of forested areas relies on responsible forestry practices, which Lundman says Modvion is committed to. The company\u2019s largest suppliers are based in Finland but its manufacturing base is in Modvion\u2019s native Sweden.<\/span><\/p>\n<p><span>This year, the firm aims to erect one two-megawatt turbine, 105 metres tall at the nacelle. Production of larger turbines with wooden towers is pencilled to commence late next year or early 2025.<\/span>\n                        <\/div>\n<blockquote><p><strong><span style=\"color: #ff6600;\">If you liked the article, do not forget to share it with your friends.
