This new breed of machines brings requisite thrills to the Great Outdoors, but without fouling the atmosphere or disturbing the peace with an internal-combustion racket.<\/p>\n<p>The latest comes from Florida-based Pelagion, whose founder and chief executive, engineer Jamie Schlinkmann, was inspired by childhood adventures on a watersports icon: A 1973 Kawasaki Jet Ski. Schlinkmann\u2019s machine, just the 213th ever built, is still one of his prized possessions. His company\u2019s Pelagion HydroBlade is an ingenious mash-up of classic stand-up Jet Skis and modern surfboard-style \u201ceFoils.\u201d Those electric-powered boards had a real breakthrough in 2020 when Facebook founder Mark Zuckerberg was spotted sailing over Hawaiian waters on one model.<\/p>\n<hr>\n<p><span data-rm-shortcode-id=\"b1192cf45f73e1160850c2d87d8d9ee0\"><iframe frameborder=\"0\" height=\"auto\" type=\"lazy-iframe\" scrolling=\"no\" data-runner-src=\"https:\/\/www.youtube.com\/embed\/Q1eWYl6HpSo?rel=0\" width=\"100%\"><\/iframe><\/span><small placeholder=\"Add Photo Caption...\">Footage of the HydroBlade Prototype During Field Testing in South Florida<\/small><\/p>\n<p>The metaverse may spring to mind the first time you see an eFoil, with its rider seeming to fly above the waves on a magic carpet. Naturally, there\u2019s no magic, only hydrodynamics. Hydrofoils work like an airplane wing, only underwater: An aerodynamic wing creates high and low pressure areas as it slices through water, generating lift with precious little drag. Add an electric motor and propeller to create thrust and you\u2019ve got a hydrofoil that doesn\u2019t require surf waves, a kite, or tow boat to generate power.<\/p>\n<p>\u201cThey\u2019re kind of like flying an airplane with no rudder and no ailerons,\u201d Schlinkmann says. \u201cYou shift your weight to fly that plane.\u201d<\/p>\n<p>There\u2019s only one problem: Powered or not, a hydrofoil takes some practice and patience to learn to ride in a standing position, especially for people with no surfing or wakeboarding experience, or so-so balance skills. To solve that, Schlinkmann\u2019s invention adds a boom-mounted canard and rudder ahead of the rider to keep the craft airborne and steady without a rider having to constantly expend energy and adjust body position. Add a trusty set of handlebars, says Schlinkmann, and the HydroBlade handles more like a vehicle with which most of us are familiar: a bicycle. Making the experience somewhat like riding a bike, he says, helps ease the intimidation factor and boost appeal for people of all ages and abilities.<\/p>\n<p>\u201cThere\u2019s a lot lower learning curve,\u201d Schlinkmann says. \u201cLike a bicycle, you lean into a curve, and add another control element.\u201d<\/p>\n<p>The design began to take shape around 2020. Schlinkmann pulled the engine and other ICE guts from his old Jet Ski and studied how he could make it electric. He realized a conventional electric Jet Ski might only have a 15- or 20-minute runtime on a single charge, which wasn\u2019t good enough. But after riding a few eFoils, the idea came together.<\/p>\n<p>\u201cThe foil improves efficiency so much,\u201d he\u2019d said. If I could make something that combined the two worlds, he thought, we\u2019d get the range and usage that\u2019s practical.<\/p>\n<p>For the HydroBlade, a pair of permanent-magnet radial-flux motors drive dual propellers at a peak 16 kilowatts (21 horsepower). They\u2019re fed by two battery packs, with a combined 600 cylindrical 2170 NCM cells and a total 11 kilowatt-hours of energy\u2014about eight to 10 times the capacity onboard a typical eFoil. A separate 1.6-kW charger can refill batteries in about 4 hours.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" title=\"Science &amp; Nature\" alt=\"Science &amp; Nature Composite of several views of the HydroBlade  and its propellers. \" data-rm-shortcode-id=\"93ae84948376ad7f07835ce8153f617a\" data-rm-shortcode-name=\"rebelmouse-image\" src=\"https:\/\/spectrum.ieee.org\/media-library\/composite-of-several-views-of-the-hydroblade-and-its-propellers.jpg?id=33082913&#038;width=980\" height=\"1080\" id=\"6145a\" lazy-loadable=\"true\" width=\"1440\"><small placeholder=\"Add Photo Credit...\">Pelagion<\/small><\/p>\n<p>Schlinkmann says the HydroBlade should cruise for about 4 hours at hair-whipping speeds of up to 70 kilometers per hour (44 miles per hour). The company is targeting a 60-mile range, enough to get from Ft. Lauderdale to Bimini on a charge. The twin battery packs weigh 58 kilograms, a bit more than half the craft\u2019s total 104 kg weight. The removable, swappable packs act as stressed members for a hull that\u2019s skinned in ABS composite. A smartphone app doubles as an electronic dashboard. Put the phone in the craft\u2019s handlebar mount and get readings including speed, state-of-charge, and telemetry.<\/p>\n<p>Putting that much juice underwater requires special attention to safety\u2014the first concern many people have about electric watercraft.<\/p>\n<p>\u201cIf you\u2019re in a Tesla and catch fire, you just get out,\u201d says Schlinkmann, a longtime Model S owner. \u201cIf you\u2019re on the water and catch on fire, you\u2019re swimming.\u201d<\/p>\n<p>Schlinkmann says the company\u2019s battery-management system monitors the health and state of individual cells and communicates along a typical CAN bus. The in-house design also fuses cells in parallel at a notably low current for cell balancing, keeping power current on a separate path.<\/p>\n<p>\u201cWe\u2019re fusing the cells at a much lower level, so if there\u2019s any cell failure, you won\u2019t have a fire,\u201d he says.<\/p>\n<p>The company is aiming to tool up production in coming months, and to bring<strong><\/strong>the HydroBlade to customers by around year\u2019s end. Initial capacity, according to the company, will be 1,000 units a year. Next time you\u2019re lolling on a beach, keep your eyes peeled for a HydroBlade\u2014because you certainly won\u2019t hear it shrieking past.<\/p>\n<\/div>\n<p><a href=\"https:\/\/spectrum.ieee.org\/electric-jet-ski\" class=\"button purchase\" rel=\"nofollow noopener\" target=\"_blank\">Read More<\/a><br \/>\n Lawrence Ulrich<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cars aren\u2019t the only conveyances being transformed by electricity.
