It may not offer infinite range, but it’s close. The new Oceanvolt ServoProp saildrive has a regeneration feature that efficiently charges up an electric boat’s batteries while sailing.
Many people think of sailboats as being purely wind powered. While smaller sailboats usually are, most decently sized sailboats have a motor for maneuvering in a marina or when the winds die down.
Saildrive motors are an innovative propulsion system commonly found on modern sailboats, offering a compact and efficient alternative to traditional shaft-driven inboard engines.
Designed with a sleek, low-drag profile, saildrives are integrated into the hull and consist of an engine mounted directly above a drive leg that extends through the hull, with a propeller at the lower end. This configuration not only reduces vibrations and noise but also minimizes the complexity of installation and maintenance.
Saildrive motors offer smooth, efficient power delivery and extra maneuverability. Their streamlined design contributes to enhanced sailing performance by reducing drag. As a result, saildrives have become a popular choice for contemporary sailing enthusiasts seeking a balance between performance, ease of use, and reduced environmental impact.
Electric saildrive motors have the benefit of offering hydro-regeneration – a unique advantage that can help recharge an electric sailboat’s batteries. When sailing under wind power, the electric motor is actually forced backwards by the water moving over the propellor. That turns the motor into a generator that can send energy back into the batteries to be used later.
An example of Oceanvolt’s ServoProp 15 variable pitch blades
Oceanvolt is widely seen as a leader in the field of hydro-regenerating motors, having racked up awards for their motors going back years, according to Plugboats. The company’s saildrives use propellors with variable pitch blades, which when combined with the motor’s ability to rotate 360 degrees, creates the most efficient environment for both propulsion and hydro-regeneration.
The company’s newest HighPower ServoProp 25 is the most powerful model in its lineup, capable of regenerating 5 kW of power while traveling at around 10 knots. According to company, future software updates that will tweak the saildrive’s performance will allow it to produce even higher power with greater efficiency.
Controlled from within the cockpit, the ServoProp 25 can switch from regeneration to propulsion with the push of a button. A readout for the operator shows the saildrive’s current operation mode, generated power, RPM, and time remaining until the 48V batteries have been recharged.
Beyond the obvious advantages over combustion engines, such as quieter operation and lack of noxious emissions, the entire system is digitally controlled to make installation simple. The water-cooling system, motor controller, and blade controller are all built into the unit, further simplifying the installation process.
When back in propulsion mode, the motor can output 25 kW continuously, though it has a peak power rating of 30 kW for 15 minutes. As is usual with electric boat motors, their lower power figure is equivalent to a much more powerful combustion engine. In this case, Oceavolt says that the 25 kW nominal power is similar in performance to a 75 kW (100 hp) combustion engine drive.
The instant torque and 5,000 newton (approximately 1,100 lb.) thrust force are major advantages of the electric setup.
The 419 lb. (190 kg) saildrive is suitable as a propulsion motor for boats up to 70 ft. in length and weighing up to 27.5 US tons (25 metric tons).
It can also be used as a hydro-regenerator alone in considerably larger vessels. Deliveries of the new saildrive are expected to begin by the end of this year.

CASE arrived at bauma 2025 with an innovative new electric wheel loader with a striking, sharp-edged design that ditches the traditional operator cab in favor of remote or autonomous operation for improved accessibility and safety.
CASE says the cabin-less design of the Impact electric wheel loader enhances operational flexibility by enabling operations in extreme environments and adverse weather conditions. It also means that job site, disaster recovery, or even rescue operations can continue 24/7, with operators in different time zones logging in for their shifts.
More important – and more practical – is CASE’s claim that the new Impact concept, “marks a significant advancement in accessibility, as operators with motor impairments and other disabilities can now operate the machine without physical limitations, representing an important step toward inclusivity in the industry.”

Along with integrated AI, a full suite of sensors, and autonomous operation built in, CASE says the Impact is a glimpse into a smarter, safer, and more sustainable working future.
Electrek’s Take
Driven by an aging workforce and not enough new talent entering the field, virtually every industrial field is struggling with an international equipment operator shortage. The concept of automation addresses some of that, but remote operation open up the field significantly, and I could easily older operators forced out of work due to injury getting back into it or younger operators halfway around the world who would give anything for an opportunity – and paycheck – like this could provide.
Smart move from CASE, and it’s great to hear them call that out specifically.
Electricity grid demands are on the rise in part due to energy-hungry technology like AI, and while experts believe renewable energy alone is not enough, it is essential to a broader supply equation. But with funding freezes, subsidy walk backs and tariffs on key components all on the table, solar, wind, and hydrogen companies are working harder than ever to make their business models work, even if they never intended to rely on federal support for the long term.
“One of the hats I used to wear was planning for the City of New York. For the longest time, there was decreasing [energy] demand,” said Aseem Kapur, chief revenue officer of GM Energy, an arm of General Motors that the company introduced in 2022. “Over the course of the last five or so years, that equation has changed. Utilities are facing unprecedented demand.”
Beyond New York City, U.S. energy demand is poised to grow upwards of 16% in the next five years, a big difference from the 0.5%it grew each year on average from 2001 to 2024, according to the Center for Strategic & International Studies.
For the renewable energy companies looking to break into the mainstream, subsidies have helped them get through their early days of growth. But President Trump has targeted these solutions from the first day of his presidency. In an executive order from Jan. 20, the Trump administration promised to “unleash” an era of fossil fuels exploration and production while also eliminating “unfair subsidies and other ill-conceived government-imposed market distortions that favor EVs over other technologies.” Last week, Trump issued an EO pushing for more coal production.
In a six-year study breaking down energy subsidies from the U.S. Energy Information Administration from 2022 (the most recent edition), 46% of federal energy subsidies were associated with renewable energy, making them the largest slice of the energy pie. At the same time, natural gas and petroleum subsidies became a net cost to the government in 2022, reversing what had been a source of revenue inflows.
“Every company I’ve talked to recognizes that subsidies were required to help them through an R&D cycle, but they all believed they had to get to a cost parity point,” said Ross Meyercord, CEO of Propel Software (and former Salesforce CIO), whose manufacturing software solution serves energy clients like Invinity Energy Systems and Eos Energy Storage. “Every company had that baked into their business model. It may happen faster than they were planning on, and obviously that creates challenges.”
Meyercord believes that clean energy companies can handle either a subsidy decrease or a rise in tariffs, but both at the same time will add substantial stress to the market, which could have negative downstream effects on the grid — and the people who rely on it.
‘Not going to get rid of fossil fuels overnight’
Like any energy source, Kapur says success always comes down to economics. In the current environment, with interest rates, and fears that inflation will reignite, he said, “it’s going to come down to, ‘What are the most cost-effective solutions that can be brought to market?'” That may vary by region, he added, but notes that solar and energy storage have already reached parity in many cases and, in some instances, are below the cost of producing energy from natural gas or coal-powered resources.
This economics equation is true even in Texas, where the state’s Attorney General Ken Paxton has voiced anti-renewables sentiment in favor of the coal market (his lawsuit against major investment firm BlackRock and others in late November claims these firms sought to “weaponize their shares to pressure the coal companies to accommodate ‘green energy’ goals”). Wind accounts for 24% of the state’s energy profile, according to the Texas Comptroller, suggesting a penchant for any energy source that’s viable and cost-effective.
“The reality is, we’re not going to get rid of fossil fuels overnight,” said Whit Irvin Jr., CEO of hydrogen energy company Q Hydrogen. “They are going to have a very significant piece in our energy ecosystem for decades, and as new technologies come out on a larger scale, the use of fossil fuels will be curtailed, but we need to continue research, development and innovation in a way that makes sense.”
Irvin emphasizes the need for innovation from all sides, including creating new technologies that have a massive impact on large scalability and carbon reduction. “We don’t want to turn off that spigot. We just want to make sure that it’s going to the right places,” he said.
Hydrogen energy itself is one such source of innovation. Hydrogen ranges in sustainability depending on the fuel it uses to source its hydrogen. For example, green hydrogen — the only climate-neutral form of hydrogen energy — stems from renewable energy surplus. Grey hydrogen stems from natural gas methane. Q Hydrogen is working to open the world’s first renewable hydrogen power plant that will be economically viable without a subsidy. Irvin Jr. says the company, which produces hydrogen using water, plans to launch its New Hampshire facility this year.
“Hydrogen fuel cells are a really good way to provide backup power or even prime power to a data center that would be considered essentially off grid,” said Irvin, likening hydrogen fuel cell production to a form of battery storage. While hydrogen is not the most economical because of its comparative immaturity, Irvin said heightened energy demand will outcompete cost sensitivity for tech companies requiring more and more data storage.
While hydrogen projects continue to reap federal incentives to propel the industry forward, Irvin said subsidies were never part of his company’s business equation. “If they do exist, we’ll be able to take advantage of them,” he said. “If they don’t exist, that will still be fine for us.”
But that might not be true for every alternative energy company depending on where they’re at in the R&D cycle. Changes in federal incentives have real power to shift the progression of renewable energy in the U.S., especially when combined with tariffs that could stifle companies’ international relationships and supply chains. Meyercord, Kapur and Irvin all foresee private industry partnerships making a huge impact for the future of the grid, but recognize that the strain is increasing as energy tech of all kinds becomes smarter and more grid-dependent.
Based on the excellent Hyundai IONIQ 5 N platform, Vanwall gives its Vandervell H-GT a high-performance aesthetic makeover inspired by the classic Lancia Delta HF Integrale. But what makes this body kit a genuine “high-performance” upgrade isn’t the way it makes the car look: it’s the 500 lb. weight savings!
Developed by Austrian racing team ByKOLLES Racing and invoking the name of a 1950s Formula 1 team, the Vandervell H-GT is essentially a new Hyundai IONIQ 5 N in aggressive, Lancia Delta-inspired carbon-fiber bodywork that the company claims gives the car an, “unprecedented weight optimization in this vehicle category.”
The H-GT’s new “thin wall” carbon fiber body slashes the car’s weight by over 230 kg (507 lbs.), which means ByKOLLES’ new Vandervell can do anything that Hyundai’s “special” IONIQ 5 N hot hatch can do. Only faster.
The car was first announced in 2023 (along with the renderings shown, below), when ByKOLLES was competing in the World Endurance Championship (WEC) with what used to be called an LMP car – but they keep changing the names of these things so it could be a Daytona Prototype, Hypercar, or even a 24 Hour LeMans Wonkavator by now.
The important part, however, is that a few of these cars have now broken cover, with ex-Formula 1 supremo, Bernie Ecclestone, having been seen trying the new-age Lancia on for size.
The Vanwall Vandervell website still shows the same €128,000 ($145,405, as I type this) price tag and specs it did in 2023, which either means they haven’t updated it in a while, were really, really good at pricing the thing in the first place, or both.
That’s presumably on top of the IONIQ N’s already hefty $66,100 price tag.
