Anyone who looks out at the ocean may feel awed by the power apparent in every wave. That power has the potential to provide energy to land-based homes and businesses, as well as floating facilities and vessels at sea. But how can we transform the ocean’s energy into usable forms, such as electricity or desalinated water?
One way to harness the ocean’s energy is through a device called a wave energy converter, or WEC. To date, WEC designs have been generally centered on large, rigid bodies that float in the water and move relative to each other as waves roll past. These bodies typically absorb ocean wave energy and focus that energy into a centralized conversion mechanism, such as a rotary generator or hydraulic piston.
Now, the National Renewable Energy Laboratory (NREL) is exploring ways to significantly advance wave energy converter design and development. With funding from the U.S. Department of Energy’s (DOE’s) Water Power Technologies Office, NREL researchers are developing concepts in which many small energy converters can be aggregated to create a single structure. With this new approach to developing wave energy, the domain of distributed embedded energy converter technologies (DEEC-Tec) could help the promise of substantial renewable energy generation from ocean waves become a reality.
Figure 1. Stretched and deformed sample volume of a flexWEC’s structure illustrating the basic use of distributed embedded energy converters (DEECs) to create power from wave energy. The sample volume has two sections where material is removed to clarify their respective arrangements: (1) the middle section has the supporting compliant material framework removed, and (2) the right section has both the supporting compliant framework and the DEECs removed. The illustration showcases how the combined semicontinuous nature of DEEC technologies supports the development of materials and structures for ocean wave energy harvesting and conversion devices.
Why Distribute and Embed Multiple Energy Converters?
One of the most innovative elements of DEEC-Tec is its ability to create flexible ocean wave energy converters, sometimes known as flexWECs. These devices have inherently broad-banded ocean wave energy absorption and conversion characteristics, meaning they can harvest energy across a wide range of ocean wave heights and frequencies.
DEEC-Tec provides a new scope of possibilities for how ocean wave energy can be harvested and converted and how flexWEC designs could power a variety of end uses both on land (powering homes and businesses) and at sea (powering navigation buoys and marine vehicles). Some of these uses will support DOE’s Powering the Blue Economy™ initiative, which aims to advance marine renewable energy technologies, such as navigation buoys or autonomous underwater vehicles, to promote economic growth in industries such as aquaculture.
“Our goal with DEEC-Tec is to vastly broaden how we currently conceptualize and envision the use of ocean wave energy,” said NREL researcher Blake Boren, who has been studying wave energy converters for over 10 years. “There is a tremendous range of possibilities for how we can develop these DEEC-Tec-based wave energy converters, and we are accelerating that exploration process.”

The yellow flexible bodies in each archetype represent the DEEC-based, compliant structures illustrated in Figure 1. (Note: Nothing is to scale; flexWEC archetype figures and scenes are solely illustrative.)
How DEEC-Tec Moves Wave Energy Forward
DEEC-Tec concepts are assembled from many small energy converters that, together, form a structure that can undulate like a snake, stretch and bend like a sheet of fabric, or expand and contract like a balloon. As the overall structure bends, twists, and/or changes shape as the ocean waves roll past, each embedded energy converter can turn a portion of that ocean wave energy into electricity.
A flexWEC has several advantages:
A broader spectrum of energy capture. With a wide range of movement and deformations available, DEEC-Tec-based wave energy converters absorb and convert ocean wave energy across a much broader range of wave conditions — both in terms of size and frequency — when compared with rigid-body converters.
Mechanical redundancy. The ability to use many hundreds or thousands of distributed embedded energy converters can ensure that ocean energy conversion occurs even if one or more of those converters stops functioning.
Resilience. The DEEC-Tec-based wave energy converter’s flexibility grants an inherent survival mechanism: the ability to ride out and absorb excessive, dangerous surges of energy from large storms and rough seas.
Favorable materials. DEEC-Tec-based wave energy converters could be manufactured from recycled materials or simple polymers. These replace heavier, sometimes more expensive materials that have historically been used for wave energy converter development, such as steel or rare-earth elements needed for large permanent magnets. Moreover, existing mass-manufacturing techniques could be used for straightforward and cost-effective DEEC-Tec component fabrication.
Easier installation. DEEC-Tec-based wave energy converters can be folded, deflated, or otherwise made compact for transport from a manufacturer to a deployment site. Likewise, for installation, they can be expanded to cover broad surface areas as needed. This would allow for robust energy capture with lower capital costs.
Reduced maintenance schedules. Monitoring the relative performance of many small devices determines the need for DEEC-Tec-based wave energy converter maintenance throughout the structure. The inherent redundancy of the structure potentially translates to less frequent inspections and maintenance requirements.
Near-continuous structural control. A DEEC-Tec-based wave energy converter is composed of numerous small transducers — mechanisms that convert one form of energy into another. Some of these can serve as simple electrical actuators, which can change the converter’s shape and movement in response to ocean wave conditions. This will allow for greater ocean wave energy harvesting and conversion control.
Bending to the Future
While there are many advantages to using DEEC-Tec in the research and development of ocean wave energy converters, there are still unknowns that need to be understood and addressed. To this end, NREL researchers are identifying the materials, structural designs, electronic systems, and manufacturing methods that could advance DEEC-Tec concepts for marine renewable energy. NREL’s work also includes DEEC-Tec subcomponent validation and codesign, computational models to simulate performance, and device proofs of concept for building and validation.
As part of this research, NREL is collaborating with outside institutions, such as the University of Colorado–Boulder, Netherlands-based energy company SBM Offshore, the U.S. Naval Research Laboratory, and Sandia National Laboratories.
Last year we reported on the storied e-bike brand Juiced Bikes falling on hard financial times and eventually closing down. Now, in a video announcement just posted to the seemingly defunct Juiced Bikes YouTube channel, the charismatic young founders of Lectric Ebikes have announced their purchase of Juiced Bikes along with their intention to revive the brand to its former glory.
Juiced Bikes was founded in 2009, making it one of the first major electric bicycle brands in the US. Operating continuously until its closure in 2024, its decade and a half of high-performance electric bicycle building created a massive fan base and a reputation for pushing the industry towards power and speed built around innovative designs instead of mere cookie-cutter copycats.
In a candid video posted to the brand’s previously abandoned YouTube channel, Lectric Ebikes founders Levi Conlow and Robbie Deziel openly shared several details about their lengthy bid to purchase Juiced Bikes and their plans to revive the company.
Now to achieve their goal, the pair will have to rely on the lessons they learned in building their own brand, Lectric Ebikes, into the largest electric bicycle company in North America.

Founded in 2009, Juiced Bikes was the epitome of old school in the e-bike industry. On the other hand, Lectric Ebikes and its two charismatic “e-bike bro” founders are the full embodiment of young e-bike whipper snappers. But despite bursting onto the scene relatively recently in 2019, Lectric Ebikes rocketed past hundreds of other e-bike brands to snatch the title of most annual e-bike sales by 2023. Clenching the title again in 2024 and likely on track for a three-peat in 2025, Levi and Robbie obviously know a thing or two about building up a successful e-bike company.
Lectric has now become known as the go-to source for the best bang-for-your-buck electric bikes, from folding e-bikes to off-road adventure-style rides, cargo e-bikes, and more. But despite Lectric Ebikes’ success, it doesn’t look like its founders intend to merely bring Juiced Bikes into the Lectric family. Instead, the duo seems to be focused on reviving the brand as it is – or at least as it was.
“What drew us into Juiced is the same thing that drew many Juiced customers into the brand in the first place,” explained Levi Conlow, CEO of Lectric Ebikes. “That high performance, that torque, that acceleration, the thing you love about Juiced. That is our full intention, to preserve and continue that beautiful performance into the future, and carry Juiced into its next 15 years. It’s had this hiccup now, but I hope that everyone has seen what we’ve done with Lectric Ebikes and has a great level of confidence in what we’re going to do.”
As Robbie and Levi explained, the process of purchasing the Juiced Bikes brand and attempting to revive it was a long and complicated journey that still seems to be taking shape. Lectric originally placed a winning bid when the brand’s assets were put up at auction in an attempt to pay back Juiced Bikes’ creditors, but the winning bid was rejected, leaving Juiced’s future in limbo. As Levi detailed, eventually he and Robbie were able to salvage a deal where they purchased nearly all of Juiced’s assets outside of its physical inventory. That means the branding, the website, the intellectual property, and pretty much everything else that was once part of the Juiced Bikes company… other than the bikes that used to line the shipping department of its Chinese factory.
And while the pair didn’t explicitly say it, we’ve since seen much of Juiced’s inventory siphoned off by a Chinese-backed e-bike brand called VeloWave, which has been selling it seemingly dropshipped online, so it doesn’t take a lot of internet sleuthing to see why they couldn’t get everything at once.
That means there’s a lot of hard work ahead of Levi and Robbie to rebuild supplier relationships and get bikes moving again. There’s also a number of disappointed Juiced customers who had placed orders for e-bikes just before Juiced collapsed last year and never received them. Levi explained that the company had hoped to fulfill those orders, and may still be able to help those customers out, but that it would take some time to get things moving again.
But while they admit that they may not be able to immediately help many of the frustrated customers or support the larger Juiced Bikes owner community with spare parts until they can build up some inventory, they appear focused on bringing the same commitment to customer service and support to Juiced that they’ve built at Lectric Ebikes.
This is of course still a developing story and we’ll be learning more soon about the backstory to Lectric’s purchase of the Juiced Bikes brand and their plans to return Juiced to its heyday. If you have questions, put them in the comments below and we’ll be sure to find out more when we sit down with Robbie and Levi soon.
Electrek’s Take
This is fascinating. We all thought that there was a chance Juiced Bikes could be saved, but it was a long shot. It meant finding someone who could convince investors that there was still hope, and not that many still saw the hope. But if there ever was, it’s with Levi and Robbie. These guys built the modern-day equivalent of a garage startup into the biggest e-bike company on the continent and almost single-handedly brought previous titans of the industry to their knees. Yet instead of merely forcing other e-bike brands out, here they are trying to save them.
And what I love about this is that it comes from a place of genuine love for the game. If you watch the video above (which you should), you can see Levi and Robbie nerding out about how great Juiced Bikes’ e-bikes were. And they’re right. Those were awesome bikes. Saving the company isn’t just about offering another revenue stream in the high-performance market that Lectric hasn’t previously focused on, but also saving an important part of the history of the nascent American e-bike market. Juiced Bikes WAS the American e-bike market for a long time, back when it was basically just those guys and Pedego… and a few weird chainstay-mounted brush motor e-bikes that looked like they had toaster-shaped batteries strapped to their rear racks.
All of this is to say that this is a really cool story, one that is currently being written, and for which we likely won’t really know how well it will work for many months to come. But damn, am I here for the ride!

A Tesla Cybertruck was split in half after another vehicle crashed into it in Frisco, Texas, a few days ago. Images of the aftermath are impressive.
On Friday, the driver of a Mercedes-Benz G Wagon lost control and crashed into seven vehicles parked on the side of the road.
The G Wagon driver was taken to the hospital in an unknown condition. He is believed to have had a medical emergency, which led to the loss of control. He was the only one injured, as no one was in the parked vehicles.
The accident is getting some attention for the aftermath.

It looks like the first vehicle hit by the driver was a Tesla Cybertruck, and it appears to have been cleanly cut in half at the bed from the impact:
At short of 6,000 lbs, a G Wagon is undoubtedly heavy, and it’s not clear at what speed it was going at the time of the impact.
There’s no doubt that it had a significant impact, but it is still surprising to see the Cybertruck’s bed ripped straight off the truck’s frame.
Some are pointing to Tesla’s use of aluminum in the Cybertruck’s frame.
Despite Tesla’s claim that the Cybertruck is “bulletproof” and made out of an “exoskeleton,” the electric vehicle’s build is actually much closer to a traditional unibody system rather than an “exoskeleton.” Most of the visible body parts, which would be part of the chassis in an exoskeleton build, are actually trims attached to the body.
Furthermore, while Tesla touts its “ultra-hard stainless steel exoskeleton,” it mostly uses stainless steel on external parts, while many parts of the frame are made of aluminum.
