Even with the obvious scientific and military applications of such a propulsion unit, scaling MHD technology up has proven difficult. But as <a href=\"https:\/\/www.youtube.com\/watch?v=Ulk4hw7pUZY\" target=\"_blank\">[Jay Bowles] of <em>Plasma Channel<\/em> shows in his latest video<\/a>, that doesn\u2019t mean you can\u2019t experiment with the concept at home. Even better, getting verifiable results is much easier than you\u2019d think.<\/p>\n<p>While [Jay] usually won\u2019t even get out of bed for less than a dozen kilovolts, a standard bench supply is all you need to power your very own MHD. He ran his experiential drive at a maximum of 25 VDC\/9 A, but he was getting results with just 5 VDC\/1.5 A. Beyond that, it\u2019s just a matter of cutting some electrodes out of metal stock and placing them on either side of the most powerful magnets you can get your hands on. Add in a 3D-printed structure and some pieces of acrylic, and you\u2019re halfway to a bathtub rendition of <em>The Hunt for Red October<\/em>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The magnetohydrodynamic (MHD) drive certainly sounds like something out of science fiction \u2014 using an array of magnets and electrodes, this high-tech propulsion technology promises to silently propel a craft through the water without any moving parts.
