CES: So very big, so little sustainability tech

Every third booth at CES showed off some new AI product or other. If you wanted to find a robotic lawn mower, throw a rock. Humanoid robots, smart locks and super thin TVs were everywhere. But if you went looking for sustainability products, you’re going to have to hunt a bit.

Last year, the Sustainability section at the Las Vegas Convention Center had 20 booths. This year, there were 38, but that’s in part due to the combination of the energy and sustainability categories. So exhibitors like South Korea’s largest electric utility company, a nuclear power company from the same country and lots of battery manufacturers. There was also an AI data platform booth in the section that had nothing to do with sustainability as far as I can tell. Guess the organizers just ran out of room for all the AI.

Within the sustainability section, and at other CES venues, I found a few encouraging displays of sustainable products — organizations and devices that were trying to address the multitude of problems the world is facing when it comes to energy production, climate and pollution.

But none of it quite achieved Engadget’s best of CES status this year. Some of what we saw was utility-scale, some wasn’t quite ready for consumer consumption and other stuff was too niche or had too many caveats to make the list. I won’t go so far as to say sustainability is dead at CES, because that sends me into dark downward spirals, but it’s getting sparse out there, friends.

Here are the companies I saw that had promise and innovative ideas. And gosh darn it, at least these guys are trying.

Spinning the Shine Turbine 2.0

Amy Skorheim for Engadget

This little guy could be a precursor to some serious personal wind power generation. That’s where the company is heading. For now, the Shine 2.0 can use as little as a light breeze to start generating power to charge your smartphones, laptops or even a power station. The whole unit weighs three pounds and sets up in around two minutes. The second generation model can output up to 75 watts and the company is working on a third version that goes up to 100 watts for even more substantial energy production.

When I approached Flint’s booth, the rep told me the company made cellulose batteries. And I thought, like paper-wrapped batteries? Nope. The chemicals inside the batteries are made from cellulose. They have a solvent-free, lithium-free, PFAS-free chemistry and break down by 70 percent in four weeks in a composting environment. They use the same basic architecture as a lithium-ion cell, with an anode, cathode and separator with ion transfers between the two. As of now, Flint is focused on partnering with manufacturers, and consumer products are on the horizon.

The Clear Drop is a soft plastics compactor that creates eight by twelve by four-inch bricks out of hundreds of grocery bags, bubble wrap, ziplocks and plastic packaging. One brick is equivalent to a 30-pound trash bag-worth of bags. Once the brick is created, it can be shipped to one of Clear Drop’s partner facilities in a pre-paid USPS shipping envelope. They currently work with a few US-based recycling facilities and hope to one day create an infrastructure to include municipal recycling.

Alpha power by CPTI

Amy Skorheim for Engadget

From what I’ve learned at the show, perovskite is the hottest thing in solar right now. It’s a mineral compound that’s been used to create more efficient solar panels. Some so sensitive to light that just indoor illumination is enough to create usable energy. Alpha Power by CPTI creates lightweight, flexible perovskite solar panels that can conform to multiple surfaces. Again, this is a company that’s partnering with manufacturers, so look for panels built into your laptop to charge it under the glare of your too-harsh office lights.

Down in the lower levels of the Venetian Expo at CES I found Green Vigor in the Hong Kong pavilion. This small company has two solutions to create energy for buildings by harnessing the potential energy from existing systems. HydroVigor generates power from water systems. So every time someone washes their hands or flushes a toilet in a building, the roof-top system generates a bit of power. CoolVigor uses the same principles to harness energy from HVAC systems. HydroVigor is currently in use in many buildings in Singapore and Hong Kong and they’re working to expand to more buildings globally.

Amy Skorheim for Engadget

This outdoor hangout spot can produce up to 10kWh of power on a given day. It’s a modular design that lets you choose louvered walls, sunshades, lights and fans when you order it and the solar panels are so strong that a full-sized human Jackery rep was able to stand on a sample panel in front of me and nothing cracked (though the company officially rates it at 20 pounds of snow per square foot). You can use the power directly, tie it into your home system, feed it into the grid or hook it up to one of Jackery’s many power stations to save the power for later. The gazebo costs $12,000 and will ship in mid-2026.

Amy Skorheim for Engadget

Engadget’s Anna Washenko does a great job of explaining the tech behind Airloom. In short it’s a roller coaster for wind that’s comprised of 40 percent less mass than a standard wind turbine and uses 42 percent fewer parts and 96 percent fewer unique parts. That makes it faster to deploy and cheaper to instal. I can also be sited in more places. Again, this is a utility-scale solution, geared towards data centers and their insatiable need for energy to power Very Important AI Things.

If you are looking for a solar-powered anything, hit up Gaotu. At the company’s booth, I saw hats, a fishing chair, a backpack, a sunbrella and a car roof-top enclosure that unfurls to charge up your Tesla. The Shenzhen-based company has been in business for 18 years and plans to just keep sticking solar panels on anything it can.

Amy Skorheim for Engadget

The single largest booth in the CES sustainability section was Segway. This year, the company showed off two new e-bikes, which our own Dan Cooper covered. This one here is the Muxi, a cargo bike with an easily swappable battery, an optional passenger seat with foot pegs and an optional middle basket. Plus a beverage cup holder.

Learn more at Segway.

If we don’t all fall into the ocean before then, perhaps CES 2027 will have a stronger showing of sustainability tech. In the meantime, I’ll take a modicum of comfort in these few brave organizations still dedicated to keeping us afloat.

CES 2026: The Tone Outdoors T1 solved the biggest problem with leaf blowers

Every fall, dozens of maple and oak trees in my neighborhood shed their leaves. Thus begins the constant drone of gas-powered leaf blowers every day through early December. The noise is by far the most annoying thing about these yard tools, but I can appreciate it’s a necessary evil — unless you prefer to pick up a blister-inducing rake.

Whisper Aero argues there’s a better way. The company is using aerospace tech to quiet the noisy devices, introducing the T1 leaf blower at CES 2026 under its sub-brand Tone Outdoors. The company promises the T1 is 80 percent quieter and 60 percent more powerful than “leading” handheld gas leaf blowers. More specifically, the T1 has 880 CFM of air flow, which easily surpasses my battery-powered EGO. And at 52 decibels of average noise at peak volume, his model is drastically quieter than any leaf blower I’ve used. I was able to confirm its lower roar on the CES show floor.

Tone says the T1 also offers extended run time of up to 50 minutes on a charge in Eco mode. That too is greater than what I get on my mid-grade EGO. What’s more, the company plans to sell a battery backpack that will extend any clean-up sessions for several hours. The T1 also has a built-in LED “nightlight” so you can still use it after dark. And since it’s quieter than what you have now, you can do so without annoying your neighbors.

Tone Outdoors T1

Billy Steele for Engadget

So, how does Whisper Aero achieve this? The company originally set out to devise a quieter solution for electric aerospace motors. Its engineers discovered that they could dramatically reduce noise and increase overall efficiency by redesigning the fan and motor. They're still pursuing that, but the company discovered its technology had other uses too.

The T1 is already available for preorder for $599 and it’s scheduled to ship in September. If you don’t care for the standard green color, you can spend another $100 for limited edition “Silence Is Golden” version. The battery backpack won’t arrive until Q1 2027 though (price TBD). Tone also says it has additional models in the works and it has a partnership with Stanley Black and Decker that will likely produce additional products with this tech on board.

Bluetti’s Charger 2 uses solar and engine power to charge your portable battery

If you’re off-roading, it’s a neat idea to use your engine to top up your battery, which prompted Bluetti to launch the Charger. You could hook it to your alternator and draw off energy as you drove to make sure you turned up to your campsite with full batteries. But if you’re also toting around solar panels on your roof, then it’s a shame you can’t also use that power to top up. This omission is what prompted Bluetti to turn up to CES 2026 with the Charger 2, which will take power from your engine and your solar panels at the same time.

Bluetti says the Charger 2’s dual-input architecture will accept 600W from the panels, 800W from the engine. All of that power will charge your batteries significantly faster than the first model, claiming it’s 13 times faster than a standard car charger. In addition, Charger 2 can manage more than one Bluetti power station and expansion batteries, should your power needs stretch. And the system is smart enough to know where the energy is coming from, managing the sources based on their availability. Plus, you can use it to jump start your engine should you need the help.

If you’re a Charger 1 owner and want to upgrade, it’s fairly painless to drop the old unit out in favor of its replacement. It uses the same cabling, so you can just hook the new model to your existing wires without having to get your fingers greasy. To reward that loyalty, the company will sell you an upgrade for $99, at least through February 7.

As for everyone else, you’ll be able to pick up the Charger 2 for $349 through February 7, at which point the price leaps to $499.

The Shine 2.0 is a compact wind turbine for your next camping trip

As power gets more dicey, personal energy generation only gets more appealing. Shine’s compact turbine isn’t going to power your house any time soon (though Rachel Carr, the company’s co-founder told me they have plans in that direction) but it can suck up the energy required to refill a smartphone in as little as 17 minutes. Of course, what it can generate depends on wind speed. That same charge could take as long as 11 hours if there’s only a slight breeze.

That power curve, and its ability to operate at night, sets the turbine apart from solar panels. Of course, on a completely still day, the Shine as inert as a becalmed sailing ship but if the wind picks up even as little as a breeze, it gets to work making power. The turbine even automatically pivots on the included stand to face into the wind.

The Shine 2.0 looks like a thin space football and has a screw-off cap that reveals a hollow compartment for the stand and tie downs. The cap then doubles as a key to unlock the blades. It all weighs just three pounds, which is impressively light considering it also houses a 12,000mAh battery that can output up to 75 watts. This is the second version of the turbine and updates include a USB-C port instead of USB-A, as well as app connectivity.

The company claims you can set the entire thing up in around two minutes. I watched the Carr take the turbine from fully closed to unfurled and ready for the stand in about that long. Unfortunately, there was no wind rushing through the CES show floor so I couldn’t see it spin, but Carr was kind enough to spin it for me.

Possibly the most exciting part is Shine’s plan for more expansive power generation. Shine 3.0, which the company is working on now, will be a 100 to 300 watt system and grid-tied turbines are on the wish list.

Pre orders are now open for the Shine 2.0 through Indiegogo for $399 and units should begin shipping this spring.

Update, January 7 2026, 4:00PM ET: This story has been updated to correct the wattage output and include the co-founder’s name.

Clear Drop is trying to do something about all those plastic bags under your sink

Even if you bring home as few bags as possible — using reusable bags, carrying purchases home with your own two hands — soft plastics sill accumulate. I certainly have a collection with one flimsy plastic sack filled with dozens or hundreds of others. I plan to do something with it… eventually.

Unfortunately, there aren’t a ton of options for what to do with those soft plastics, as most recycling facilities can’t accept them. But no one likes seeing them end up in oceans and rivers and stuck up in trees. So I was excited to see the Clear Drop Soft Plastic Compactor (CPC) at CES. It’s a pre-recycler for your home that turns hundreds of bags into a solid brick that’s easier to transport. Certain facilities can accept the bricks for recycling.

Clear Drop works with 95 percent of soft plastics, sucking up bags, bubble wrap, ziplocks, package wrap and cling film into its maw. It then compresses and heats the plastic to form a compact eight by twelve by four inch brick. I asked Matt Daly, Clear Drop’s head of product, what the compactor can’t take and I was told you can’t add ping pong balls, IV bags and camera film. Easy enough.

It was satisfying to see the little slot on the top gobble up the plastic bags Daly fed it. The Clear Drop wasn’t set to smash and heat at the show, but I was assured by another Clear Drop rep that any plastic smell produced during operation was minimal and the company performed safety tests to ensure the machine didn’t create any harmful emissions.

Daly said it would take about a month for most households to create a brick, which translates to around a 30 gallon trash bag full of other bags. Once that brick is created, it can be shipped to one of Clear Drop’s partner facilities and pre-paid USPS shipping envelops are included. They work with multiple US-based recycling facilities and do audits to ensure the bricks are actually being recycled.

Of course, I was a little disappointed the bricks couldn’t be tossed in my blue curbside bin, but Daly said they’re working to bring more recycling partners on board and the ultimate goal is to create an infrastructure that would eventually include municipal recycling. Shipping the bricks somewhere feels a little counterproductive, eco-wise. And the machine itself is not cheap. The price is split up over the course of two years, but it adds up to $1,400.

I’m happy to see someone somewhere is doing something to address a pretty clear problem. While it’s not perfect, this is probably the best household-level solution I’ve seen to that can ensure your bags don’t go down some sea turtle’s throat.

Birdbuddy’s new smart bird feeder can ID birds by their songs

I’m seeing a ton of smart bird feeders again this year at CES — and I’m inexplicably drawn to them. Perhaps because the idea of birds nibbling on seeds and flying away represents a natural purity and freedom that doesn’t exist within the halls of CES. Birdbuddy was one of the first smart bird feeder brands, with a wildly successful Kickstarter back in 2020. And this year, they’ve added birdsong to their species identification capabilities.

Two new feeders, the Birdbuddy 2 and the Birdbuddy 2 Mini both have the new feature, but the latter is a more affordable, starter version. The Bird Buddy 2 is solar-powered with built-in panels. It’s slightly larger and has a bigger seed capacity, too. Both have HD cameras you can manually position either vertically or horizontally and both have a mic to help with birdsong IDs.

Upgrades to the cameras include a faster wake-up time when a bird lands and the housing for the seed and camera has a more modular design that makes the feeder easier to clean. The lens is now protected by Gorilla Glass, which may seem excessive, but Rhian Humphries, Birdbuddy’s senior PR manager, said curious birds often peck at the camera looking for more food.

The AI Birdbuddy uses was trained on real bird visits and at the end of each day, you’ll get a “postcard,” a curated look at the birds that visited your feeder that day. Of course, the app can also alert you each time you have a feathered customer in your yard so you can tune into nature’s live feed and soothe your soul for a few.

The Birdbuddy 2 goes for $199. It sold out during the pre-order phase, and those units will ship in February, but more will be available in mid 2026. The Birdbuddy 2 Mini costs $129 with pre-orders opening in summer.

Airloom will showcase its new approach to wind power at CES

One of the many concerns about artificial intelligence these days is how the rush to build data centers is impacting local communities. Data centers can create a drain on resources, and some utility companies have already said customers can expect to see their electricity bills growing as these facilities increase demand. There have been some discussions of what other power sources could support the AI engine, and wind power specialist Airloom is one company that's looking to address the problem. Ahead of the business' upcoming appearance at CES, we've learned a bit about what Airloom has accomplished this year and what it is aiming for next.

Rather than the very tall towers typically used for this approach, Airloom's structures are 20 to 30 meters high. They are comprised of a loop of adjustable wings that move along a track, a design that’s akin to a roller coaster. As the wings move, they generate power just like the blades on a regular wind turbine do. Airloom claims that its structures require 40 percent less mass than a traditional one while delivering the same output. It also says the Airloom's towers require 42 percent fewer parts and 96 percent fewer unique parts. In combination, the company says its approach is 85 percent faster to deploy and 47 percent less expensive than horizontal axis wind turbines. Airloom broke ground on a pilot site in June for testing out its approach and confirming how those figures work in practice.

It’s not feasible to bring a wind farm, even a small one, into CES, but Airloom will have a booth at the event with materials about its technology and engineering. While the business isn't in a consumer-facing field, the impact of Airloom's work could have a future positive impact on people if the data center boom continues.
