But that\u2019s not all: to be charged, Stella doesn\u2019t through the standard land-based charging route, but it uses solar panels. This is an excellent development in terms of technology, research, and especially maneuverability when sailing.The choice of the Torqeedo Pod engine was quite immediate and natural, particularly because of what it ensures. <strong>Torqeedo<\/strong> has a leading role in the market and offers not only a quality service, but also, its spare parts are easy to find. Finally, there is another aspect that shouldn\u2019t be ignored, that of hydrogeneration: <strong>the Torqeedo Pod engines become &#8220;hydroelectric power plants&#8221; that sail and charge the battery<\/strong>. When the propeller turns at the speed of movement through the water, that movement is transformed into a battery charge.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img width=\"904\" height=\"452\" src=\"https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/02-BIGA-270.jpg\" alt=\"\" class=\"wp-image-4567\" srcset=\"https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/02-BIGA-270.jpg 904w, https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/02-BIGA-270-300x150.jpg 300w, https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/02-BIGA-270-768x384.jpg 768w, https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/02-BIGA-270-585x293.jpg 585w\" sizes=\"(max-width: 904px) 100vw, 904px\" \/><figcaption><em><em>Christian Gr\u00f6bm\u00fcller poses aboard his gem.<\/em><\/em><\/figcaption><\/figure>\n\n\n\n<p>This is a process under the banner of sustainability, which thus allows for several advantages:<\/p>\n\n\n\n<ul style=\"font-size:16px\"><li>The boat is sustainable<\/li><li>It doesn&#8217;t require much maintenance<\/li><li>It\u2019s silent and doesn\u2019t cause unpleasant odors while sailing<\/li><li>Its engine is lighter and smaller than a classic diesel engine<\/li><li>It presents enough space to provide extra energy storage system<br><br><br><\/li><\/ul>\n\n\n\n<h2><span class=\"ez-toc-section\" id=\"Electromobility_doesnt_mean_%E2%80%9Cgiving_up_something%E2%80%9D\"><\/span>Electromobility doesn\u2019t mean &#8220;giving up something&#8221;<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>When sailing in the absence of wind, Christian ensures a journey powered by electricity, generated by <strong>a permanently installed solar power system<\/strong>.

When it is sunny, you can reach two knots without taking power from the battery; <strong>at four knots, 30 percent of the power comes from the sun<\/strong>. In Gr\u00f6bm\u00fcller&#8217;s direct experience, he has noticed that when there are good wind and sun conditions, <strong>batteries rarely drop below 85 percent charge<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img width=\"904\" height=\"452\" src=\"https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/03-BIGA-270.jpg\" alt=\"\" class=\"wp-image-4569\" srcset=\"https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/03-BIGA-270.jpg 904w, https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/03-BIGA-270-300x150.jpg 300w, https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/03-BIGA-270-768x384.jpg 768w, https:\/\/www.deutzmag.com\/wp-content\/uploads\/2023\/11\/03-BIGA-270-585x293.jpg 585w\" sizes=\"(max-width: 904px) 100vw, 904px\" \/><figcaption><em><em>A shot of the Torqeedo Cruise Pod engine that equips the Stella boat ensuring emission-free sailing.<\/em><\/em><\/figcaption><\/figure>\n\n\n\n<p>As Christian explained, <strong>choosing electromobility does not mean &#8220;giving up something&#8221;.<\/strong> Such light and stress-free navigation, the implementation of solar panels and battery charging offer typical advantages of a combustion boat.

It all started during 2021: before the Covid-19 pandemic, Gr\u00f6bm\u00fcller was working for a U.S. sales company. He then chose to quit his job and relaunch himself professionally as a sailing instructor, the profession he had always wanted to do since he was a child.<\/p>\n\n\n\n<p>Now that his dream has become reality, he certainly has no intention of stopping.
