Scientists Use Waverider Buoys To Conduct Wave Energy Research
Mike Muglia hates to miss a wave.
A self-described surf junkie, Muglia catches waves on his surfboard off the coast of the Outer Banks in North Carolina. Further into those waters—15 nautical miles to be exact—sits another surfer. Aptly named Waverider, this surfer is a 440-pound, half banana-yellow, half beet-purple buoy that Muglia uses to study the energy that flows in our oceans.

Marine energy—clean power generated from ocean currents, waves, tides, and water temperature changes—is still young, but it has the potential to deliver clean, renewable electricity to coastal communities where nearly 40% of Americans live. Before that can happen, scientists need to pinpoint which oceanic arteries host the most reliable energy. With 3.4 million square nautical miles of U.S. waters—a larger area than the combined landmass of all 50 states—there is a lot left to explore.
Now, Muglia and Miguel Canals just deployed two new Waverider buoys—one off the coast of North Carolina and the other off Puerto Rico. There, the surfers will collect detailed data on the surface waves in those areas of the Atlantic Ocean, adding to publicly available data sets on waves, currents, and water temperatures that will not only move marine energy closer to widescale use but also help scientists understand how climate change is affecting our oceans.
Muglia is a principal investigator at the Southeast Atlantic Coastal Ocean Observing Regional Association and research professor at the Coastal Studies Institute of North Carolina, and Canals is a principal investigator at the Caribbean Coastal Ocean Observing System in Puerto Rico.
“We want to characterize the wave energy resources available,” said Canals, who, like Muglia, surfs the same waves he studies. “But we also want to collect long-term data on waves to understand the ocean and the changing climate for the benefit of future generations.”
The National Renewable Energy Laboratory (NREL), which owns the two Waverider buoys, partnered with ocean experts Muglia and Canals to collect this critical new data. This NREL-led effort is part of a larger, nine-year project funded by the U.S. Department of Energy’s Water Power Technologies Office. The collaborative, multi-institution study generates the resource data that technology and project developers need to design the next generation of devices. No one institution (or buoy) can collect it all, which is why partners like Muglia and Canals are so valuable. The data these partners generate are used to verify and improve model accuracy, and are also valuable on their own as detailed records of the real ocean. The data from this project—both the measurements and the models that use them—is publicly available on the Marine Energy Atlas.
“The ocean,” said Levi Kilcher, a physical oceanographer at NREL who leads the Waverider and Marine Energy Atlas projects, “is an extremely challenging environment. But we’re starting to see success, which makes it a very exciting time to be in this industry.”
On Aug. 2, 2021, Muglia set off in the Miss Caroline with a deckhand and marine mammal observer, who watched for sea turtles, dolphins, and other wildlife that might swim too close to the boat. For the 40-nautical-mile, three-hour trip, the bulbous Waverider buoy sat secure in a rubber tire on the back of the small skiff. When the Miss Caroline cruised to the selected spot—indistinguishable from the surrounding waters except by GPS—the team scanned the area for underwater obstacles before anchoring the Waverider under an almost-cloudless, blue sky.
From their lonely ocean homes, the two buoys will send live data back to Muglia’s and Canals’ teams using satellite communications systems. Solar panels help power those systems, and flashing lights alert boats to keep a safe distance.
Now, Muglia, Canals, and their colleagues and students wait impatiently for the first batch of data to stream in. Wave energy researchers and engineers are also waiting impatiently. Using high-quality data on how the ocean moves, they can design wave energy converters that are better tailored to extract energy from the motion of the ocean surface.
The data can serve climate and environmental scientists, too.
In the tropical Puerto Rican waters, violent winter storms and summer hurricanes can create energetic seas. Canals and his team chose their buoy site specifically for its high energy potential—those waves pack power—but the data can also help researchers understand how extreme wave events impact the coastal environment. So far, Canals has only lost one buoy in Puerto Rico—to Hurricane Maria. It was recovered two weeks later off the Turks and Caicos Islands.
Canals, who successfully deployed his Waverider on June 15, 2021, also chose his site because the seabed lacked a significant population of benthic organisms—seabed dwellers, like clams, oysters, sea stars, or sea cucumbers—or sensitive habitats. “There’s just sand and mud,” he said, “which makes it an ideal location for the anchor deployment.”

Neither Canals nor Muglia, who monitor multiple offshore buoys, have ever seen wildlife get tangled in buoy moorings. In fact, they have seen the opposite: The buoys attract shoals of slender, mud-colored Cobia and big-nosed, neon-yellow mahi-mahi, which like to swarm the bobbing devices.
And the Waveriders are not just for fish and scientists.
By streaming the buoys’ measurements to North Carolina’s Jennette’s Pier aquarium, which welcomes about 250,000 visitors a year, “the public can walk in and see what the wave heights are, see what the water temperature is, see what the ocean surface currents look like off the coast of North Carolina,” Muglia said.
You can find the same data from any computer anywhere in the world: With an online data feed available through the Coastal Data Information Program, surfers like Canals and Muglia can check for dangerous currents, frigid temperatures, or flat waves before heading out on their surfboards. It can also help law enforcement navigate volatile waters to catch up with offshore lawbreakers.
“Even though the main purpose is for resource characterization,” Canals said, “the buoy will have a lot of applications for surfers, fishermen, paddleboarders, divers, law enforcement, coastal managers, and boaters.”
Both buoys now float near the Gulf Stream, which swings through the Gulf of Mexico (near the Caribbean Coastal Ocean Observing System on Puerto Rico’s northern coast) and hooks around Florida before heading up the east coast to Canada. With its warm and nutrient-rich waters, the Gulf Stream is a major regulator of the world’s climate, feeds marine wildlife, and helps their populations thrive, so the U.S. fishing industry can thrive, too.
Still, Muglia said, “What happens down here is not well understood.” Those rich, energetic waters could help power coastal communities with clean energy. But, if their temperatures shift or their speedy currents slow, that could disrupt global weather and climate, potentially causing more violent storms in Europe or higher sea levels in major U.S. cities like Boston and New York.
The two Waverider buoys will help both marine energy developers and climate scientists better understand these mysterious waters.
For now, as he waits for the data, Muglia is guaranteed to never miss another wave—either on his surfboard or in his laboratory—with the Waverider surfing offshore.

Tesla’s stock (TSLA) crashed by as much as 5% in pre-market trading after President Trump threatened to set DOGE on Elon Musk, who has been criticizing his ‘Big Beautiful Bill’.
After being kindly shown the door to the White House last month, Musk had a brief moment of clarity and started to criticize Trump and the Republican party, which he helped elect with almost $300 million of his own money in the 2024 elections.
He highlighted how Trump’s “Big Beautiful Bill” is expected to increase the deficit and debt. The Tesla CEO even linked Trump to Jeffrey Epstein, something that has been well known for decades, but Musk conveniently ignored it as he was backing the President and wearing hats that read, “Trump was right about everything.”
Musk quickly calmed down and even apologized for “going too far” and started praising Trump again.
That didn’t last long.
Over the last few days, as the Senate attempts to pass Trump’s budget and tax bill, Musk has renewed his efforts to halt the legislation.
The CEO appeared to renew the attacks after the Senate updated the bill to kill the EV incentive sooner and to increase taxes on solar and wind projects.
However, Musk said that he doesn’t mind EV and renewable energy subsidies going away, but he believes that fossil fuel subsidies should also be removed, which is not in the plans at all.
Trump campaigned on Musk’s money, claiming that he would get America to “drill, baby, drill” again.
The CEO went as far as threatening any Senator who vote for the bill, all Republicans, to face his money in their next primary. He added that if the bill passes, he will create a new “America Party.’
Musk’s attacks have focused on the bill itself and the Republicans voting for it, but Trump likes to call it his bill, and unsurprisingly, he is unhappy with Musk.
Last night, he took to Truth Social to highlight again that Musk “would probably have to close up shop and head back to South Africa” without US government subsidies.
The President then suggested that he could have DOGE, a department that Musk created, go after him and the subsidies that his companies get:
Elon Musk knew, long before he so strongly Endorsed me for President, that I was strongly against the EV Mandate. It is ridiculous, and was always a major part of my campaign. Electric cars are fine, but not everyone should be forced to own one. Elon may get more subsidy than any human being in history, by far, and without subsidies, Elon would probably have to close up shop and head back home to South Africa. No more Rocket launches, Satellites, or Electric Car Production, and our Country would save a FORTUNE. Perhaps we should have DOGE take a good, hard, look at this? BIG MONEY TO BE SAVED!!!
Tesla’s stock dropped by more than 4% in pre-market trading following the President’s threat.
Musk responded to the President by pointing out that he is asking to remove the subsidies, but he didn’t add his usual caveat of also removing all subsidies for fossil fuel.
Electrek’s Take
It’s both sad and funny to see Elon now. It’s sad because the US is plunging back into an energy dark age of relying on fossil fuels. Still, it’s amusing because Elon is acting as if he’s just now realizing what he has done, despite everyone but a few cult members screaming at him that this was going to happen for the last year.
Elon got what he wanted out of Trump with his $300 million, and now, he realizes that his influence has limits and that Trump is going to do way more damage than just what Musk wanted out of him: to stop illegal immigration and the so scary “woke mind virus.”
The result will be a significant blow to the growth of electric vehicles and clean energy in the US, and Tesla will be affected in the process, exactly what we have been saying for the last year.

Police across the US are cracking down on illegal use of out-of-class e-bikes or non-street-legal electric motorcycles used on public roads. It used to be that if you sped off on an illegal electric dirt bike or mini bike after a traffic stop in California, there was a good chance you’d get away. Most police departments don’t want to engage in high-speed chases over these types of violations, especially if the rider isn’t wearing a helmet or is weaving through dense traffic. And since these types of bikes almost never have license plates, merely outrunning or outmaneuvering a police cruiser through some bushes or over a sidewalk was usually enough to evade justice. But lately, a new kind of chase is happening – from above.
Several California police departments are now turning to small, simple-to-operate drones similar to consumer drones to track down illegal e-bike and electric dirt bike riders who flee traffic stops.
These drones, often built on platforms used by consumer drones but with upgraded camera equipment, are quiet, effective, and don’t put pedestrians or officers at risk like a high-speed pursuit.
And while the tech isn’t new, the way it’s being deployed marks a turning point in how cities are responding to the rise of unregistered, high-powered electric motorbikes and minibikes on public roads.
Recently, the Irvine Police Department shared details on how they caught a minor who was illegally operating a Stark Varg electric dirt bike on public roads and then sped away from police attempting to conduct a traffic stop.
“A 16-year-old juvenile recklessly fled from officers during an attempted traffic stop on Jamboree, reaching high speeds. The rider ran multiple red lights, placing innocent lives in danger. Thankfully, with the assistance of our drone team, officers quickly located the teenager and safely took him into custody. He was later released to his parent. The juvenile was unlicensed, and the motorcycle was purchased by a parent who knowingly allowed their child to ride it. That parent was cited, and the motorcycle was impounded.”
In a similar case just a few weeks ago, the Desert Hot Springs Police Department used a similar drone setup to catch a juvenile illegally operating a non-street-legal minibike on public roads.
As the department shared in a social media post mocking the rider, “Officers attempted to stop a suspect illegally riding a mini bike on city streets. Instead of pulling over like a reasonable person, he chose to flee… on a mini bike. Little did he know, our drone team was already in the air and had front-row seats to this low-speed drama. They followed him as he weaved through traffic, blew through stop signs, and ultimately led us right back to his own front door.”
The DHSPD explained that after the drone watched from above and followed the rider home, police officers arrived and knocked on his front door, which he promptly answered. “He was arrested at his residence without incident,” the post continued. “The mini bike? Impounded. The escape attempt? Hilarious.”
Some police departments in California are still employing police helicopters as their go-to “eye in the sky” for tracking Sur-ron riders who try to run from police, but these light and inexpensive drones are proving to be a more cost-effective and efficient alternative.
The rise of unregistered and often illegally modified electric motorbikes that don’t fit inside existing three-class electric bicycle regulations – many of them closer to light motorcycles than bicycles – has created a real challenge for cities. Riders can disappear down alleyways, weave through traffic, or vanish into neighborhoods where a patrol car can’t follow.
But a few grand for a simple drone? That’s a safer, cheaper solution that can hover and follow quietly from above, sometimes all the way to a suspect’s front door.
This drone-based enforcement strategy raises some interesting questions – not just about surveillance, but about how cities will regulate a fast-evolving micromobility landscape. As out-of-class electric bikes and light electric dirt bikes blur legal categories and create enforcement gaps, tech like drones is stepping in to close them.
Whether that’s a good thing or not depends on your perspective. But one thing’s for sure: the days of just gunning it and getting away are coming to an end.

The Dodge Charger Daytona EV made headlines when it rolled out fake engine noises as a way to make the EV appeal to muscle car drivers. As it turns out, they weren’t the right sort of fake engine noises – and now Stellantis has to recall 8,000 of them for a fix.
According to the ChryCo fans at Mopar Insider, Stellantis is recalling ~8,390 examples of its 2024 to 2025 Dodge Charger Daytona EVs because of an exterior amplifier that may be missing critical enabling the amp to emit exterior sounds – including the Federally mandated pedestrian warning sounds designed to keep pedestrians safe.
What’s more, the recall’s “suspect period” reportedly begins on 30APR2024, when the first 2024 Dodge Charger Daytona was produced, and ends 18MAR2025 … when the last Charger EV was produced.
RECALL CHRONOLOGY
- On April 17, 2025, the FCA US LLC (“FCA US”) Technical Safety and Regulatory Compliance (“TSRC”) organization opened an investigation into certain 2024–2025 model year Dodge Charger vehicles that may not emit exterior sound.
- From April 17, 2025, through May 13, 2025, FCA US TSRC met with FCA US Engineering and the supplier to understand all potential failure modes associated with the issue. They also reviewed warranty data, field records, and customer assistance records to determine field occurrences.
- On May 14, 2025, the FCA US TSRC organization determined that a vehicle build issue existed on certain vehicles related to a lack of EV exterior sound, potentially resulting in noncompliance with FMVSS No. 141.
Without the software patch, the vehicles don’t comply with the requirements of Federal Motor Vehicle Safety Standards (FMVSS) No. 141, “Minimum Sound Requirements for Hybrid and Electric Vehicles.” The rule requires noisemakers for EVs and hybrids when operating under 19 mph, the safest speeds for pedestrians.
Basically, if you have a Dodge Charger EV, expect to get a recall notice.
It just keeps getting funnier
If you’re not familiar with the Charger Daytona EV’s “Fratzonic Chambered Exhaust,” it’s a system that employs a combination of digital sound synthesis and a physical tuning chamber (translation: a speaker) to produce a 126 decibel sound that approximately imitates a Hellcat Hemi V8 ICE. That’s loud enough to cause most people physical pain, according to Yale University – putting it somewhere between a loud rock concert and a passenger jet at takeoff.
While you could argue that such noises are part and parcel with powerful combustion, they’re completely irrelevant to an EV, and speak to a particular sort of infantile delusion of masculinity that I, frankly, have never been able to wrap my head around. Something akin to the, “Hey, look at me! I’m a big tough guy!” attention-whoring of a suburban Harley rider in a “Sons of Anarchy” novelty cut, without even enough courage to ride a motorcycle, you know?
You know – and I bet you can help me dial in the the comparison to perfection (and help me explain why the car just isn’t selling) in the comments section at the bottom of the page.
