Leaky homes and buildings are some of the greatest climate offenders, but a Dayton, Ohio-based start-up is making big gains in shoring up the problem. Aeroseal, which seals both air ducts and building envelopes, is now available across America and in 29 countries.
Leaky airducts and walls are the single largest reason for wasted energy in homes. Typical systems can lose between 25% and 40% of the heating or cooling energy put out. While newer homes are built more tightly, old homes are major culprits. Reducing that wasted energy not only lowers consumers’ bills, but also reduces emissions associated with energy production, which are a significant contributor to climate change. Overall, heating and cooling residences and businesses accounted for 13% of the world’s greenhouse gas emissions in 2020, according to the U.S. Environmental Protection Agency.
Since air ducts are often inside the walls, sealing them can be difficult, but this technology does it from the inside, working through the ducts without ever cutting into a wall.
“What we have done is we have found a way to seal the air ducts in the building envelope without physically getting access to the leaks,” said Aeroseal CEO Amit Gupta.
The system is relatively simple, and akin to fixing a flat tire. It first pressurizes the ducts or building envelope with a fan, then injects micron-sized particles, which, as they try to escape the building or any space, automatically adhere to the gaps and seals them. The particles are made of a non-toxic, non-flammable emulsion of water and vinyl acetate, according to the company, which adds that these are some of the same ingredients found in pacifiers and chewing gum.
Gupta says sealing the average-sized home would cost about $2,500, but claims the investment will pay for itself in energy cost savings within four years.
“Everybody should fix this. Not only they will make their house comfortable, they will also make their house more healthy because they won’t be sucking in air from attics or from the crawlspace or between the walls,” added Gupta.
Aeroseal is working with big builders like DR Horton, Lennar and Beazer, and midsized builders like Denver-based Thrive.
“We built our brand on energy efficiency, and this is really the most foolproof way to get there,” said Gene Myers, CEO of Thrive. “I think energy efficiency and carbon reduction go hand in hand, and we’re really focused on carbon reduction in our company.”
Aeroseal has so far raised about $30 million in venture capital from the likes of Breakthrough Energy, Energy Impact Partners, Building Ventures and 2150.
Save $200 on Anker’s SOLIX EverFrost 2 40L and 58L electric coolers and bundles starting from $700
Looking back in on Anker’s SOLIX Mother’s Day Sale which is continuing through May 11, we wanted to shine a spotlight on the deals for brand’s latest release, the EverFrost 2 Portable Electric Coolers. You’ll find the 40L model discounted to $699.99 shipped here (matching at Amazon), while its 58L counterpart is down at $899.99 shipped (also matching at Amazon), as well as alternate bundles that give you a secondary removable battery below. These two models would normally run you $900 and $1,100 at full price, with these prices only having been beaten out by the February pre-sale launch discounts to $600 and $800 from Anker, while the 58L model saw a drop to $809 from Wellbots. We’ve been seeing these same discounts repeat in recent sales, bringing you another chance at $200 off the going rates for the best post-launch prices we have tracked. Head below for more information on these coolers and their bundle options, or you can get our hands-on take from our review here.
Currently only sporting the two mentioned model sizes (though there is a smaller 23L cooler slated to hit the market later in the year), Anker’s SOLIX EverFrost 2 Electric Coolers see to it that ice runs will no longer be needed during gatherings and other events. There’s currently the 40L model that provides a single compartment with dual functionality and the 58L model that has two compartments – each with dual functionality – that can cover simultaneous cooling and freezing. The big change from its predecessors is the trading of a direct cooling system for the new air-cooled system, providing compartment cooldowns at much faster speeds.

Both the 40L and 58L models have been given dual battery ports (with the second battery either being sold separately or within bundles that you can find below), which provide up to 104 hours of continuous runtime when set to Eco Mode, according to Anker. Each of these batteries come with a 288Wh capacity and can also be repurposed as power banks when not running the coolers, giving you a little added versatility to keep personal devices juiced up with either the 60W USB-C or 12W USB-A ports. There are four ways to recharge the batteries – with a max 100W solar input, plugging the cooler into a wall outlet or 12V car port, or you can use a USB-C connection directly to the batteries. Both models sport IPX3 water-resistance ratings, as well as large 6-inch wheels for semi-rough terrain and a fold-down tray that is also used as a handle. You can get a full rundown on what to expect in our hands-on review here.

Get serious cargo-hauling power on G-Force’s DE-S premium all-terrain e-bike with 160-mile range for $1,399
Despite G-Force’s Spring Sale e-bike offers slated to end with April, it appears that the brand has extended the savings, giving folks a little more time to score them at these lower prices before rates are raised down the road due to tariffs. Among the continuing deals, the brand’s latest release, the DE-S Premium All-Terrain Fat Tire Wide Cargo e-bike is still being offered at $1,399 shipped. This new model normally carries a $1,799 price tag, with things uncertain as to how high it may rise in the future, with the brand’s previous Spring Sale bringing costs down to this same rate last month. It’s a solid $400 off the going rate while things last, with this being the lowest price we have tracked since the brand came onto our radar.
A serious model with equally serious cargo-hauling capabilities, G-Force’s DE-S e-bike comes with a 750W brushless geared hub motor alongside a waterproof and flame-retardant 45Ah removable battery in order to provide you with 28 MPH top speeds and up to 160 miles of pedal-assisted travel on a single charge. While this bike comes with a cadence sensor, the brand has also equipped it with an additional PAS sensor that allows the rider to control the e-bike’s output power, “eliminating the need for a torque sensor to achieve a smooth riding experience,” according to the brand.
It’s got a solid array of features that make the riding experience all the better, like the smoothed-out cruising thanks to the adjustable front fork suspension paired with the rear suspension system, further bolstered by the fat tires. Alongside these, there’s also hydraulic mineral oil brakes, a 7-speed Shimano derailleur, a 48V LED “ultra bright” headlight, an integrated taillight, an extended rear cargo rack that supports multiple load modes (cargo, passenger, child seat installation, more), hidden cable routing, removable pedals, a telescopic comfort saddle, and a backlit LCD display.
EcoFlow offers flash sale on 2,048Wh LiFePO4 DELTA 2 bundle with an expansion battery and bag at $849 (Today only)
As part of its ongoing Spring-to-Summer sale, EcoFlow has launched another 24-hour flash sale with two offers – one to provide backup power support while the other provides solar support to your power stations. The first of these offers gives you a DELTA 2 Portable Power Station bundled alongside a Smart Extra Battery (expansion battery) and a bag for $849 shipped. The combination of the station and battery would normally cost you $1,798 at full price, which we’ve been seeing in the brand’s direct 2025 sales usually falling to $949. This means that you’re getting the additional travel bag with a further $100 markdown, one of the best prices we have tracked that is also currently matching on Amazon, though, without the bag.
This is quite a solid combination for short-term off-grid power needs, as well as at-home emergency backup. With the inclusion of the extra battery, EcoFlow’s DELTA 2 power station goes from a 1,024Wh to 2,048WH LiFePO4 capacity, which you can further expand to 3,072Wh with another battery connected. It delivers up to 1,800W of steady output through its 15 port options, which surges to 2,200W for larger needs. There’s the usual array of smart controls available through its companion app, as well as the unit coming with an IP68 waterproof construction, knowing that it’ll likely accompany you out into the wilds of the world.
The station’s battery can be recharged in a short time thanks to the fast-charging tech that the brand has given it, letting you refill 80% of its battery in just 50 minutes via a wall outlet, with things taking a little longer at 80 minutes to get it back to full. Of course, there’s also the solar charging capabilities if you have or plan to buy the appropriate panels, with a max 500W input that can recharge the battery in three to six hours, depending on weather conditions.
EcoFlow is also providing the opportunity to grab two of its 110W Solar Panels at $329 shipped while these flash savings last. Outside of this discount, the panels are currently going for $209 each (and regularly run $399), making this is a great chance to score both at about $165 each, giving you the means to recharge the above station’s – or any other model – battery with the sun’s rays.
The savings this week are also continuing to a collection of other markdowns. To the same tune as the offers above, these all help you take a more energy-conscious approach to your routine. Winter means you can lock in even better off-season price cuts on electric tools for the lawn while saving on EVs and tons of other gear.

Rivian founder and CEO RJ Scaringe just posted a fresh image of a Maximus drive unit—a vital component teased for some time now that will be a key piece in Rivian’s goal to reduce the cost per drive unit in its R2 EV builds.
Rivian continues to show strength during uncertain times in the automotive industry, particularly regarding legacy automakers’ electrification strategies. While threats to EV adoption linger, demand for Rivian’s American-made BEVs has stayed high despite a slight dip in deliveries last quarter.
The company is still riding the success of its first two flagship models—the R1S and R1T, which are now in the second generation. Better still, fans of the brand and EV enthusiasts alike are highly anticipating the arrival of Rivian’s encore to the R1 models, the R2, which will then be followed by a smaller R3 and a rally-like R3X.
As a young automaker, Rivian has overcome hurdles to establish itself in the EV industry, finally achieving scaled production at its Normal, Illinois, facility. Part of that strategy includes consistent innovation and improvement to improve vehicle function and performance for its customers and optimize manufacturing to reduce overall cost.

An excellent example of that evolution is Rivian’s Enduro drive unit, which was implemented on dual-motor versions of the R1T and R1S. Since then, Rivian has been teasing a new drive unit called Maximus, which we thought may also make its way into R1 builds, but have since learned will debut in the upcoming R2 EVs.
Today, Rivian founder and CEO RJ Scaringe offered a close-up look at Maximus being developed within the R2 design. Check it out:

RJ teases the Maximus drive unit in the Rivian R2
According to RJ Scaringe, the image above is Rivian’s new Maximus drive unit configuration implemented in the R2. There’s not much else of the upcoming BEV to see here, but an exciting little tidbit nonetheless.
While most consumers have been attracted to the Rivian R2’s size and look, Maximus will play a key role in Normal as the American automaker works to reduce the per-unit cost of its drive units—a primary goal it has previously shared with the public.
One key improvement we already know about is Maximus’ stator windings—one of the key components of any electric motor. Previously, Rivian shared that Maximus uses a new continuous winding technique that reduces the total welds per stator and thus the total overall cost of building each one. For comparison, Rivian’s current Enduro drive unit requires 264 stator welds, while Maximus only needs 24.
Rivian has also integrated the front rotor shaft and gear into a single forged, CNC-milled component and reduced the number of required bearings. The result is a simpler, more compact drive unit that is cheaper to build and weighs less, which is excellent news for EV range and efficiency.
With Maximus development underway, Rivian appears to remain on track to officially launch the R2 next year as promised. Be sure to check back with Electrek often for the latest Rivian news about the R2 and beyond.

Rivian (RIVN) is charging ahead with another major project. The EV maker is building a new 1.2 million-square-foot supplier park near its Normal, Illinois, manufacturing plant as part of a nearly $120 million investment. With a $16 million incentive package from the state, Rivian expects it to be “a key enabler” as it ramps up EV production.
Rivian to get $16 million for a new supplier park
Rivian and Illinois Governor JB Pritzker announced the new supplier park on Monday. The nearly $120 million investment will create about 100 direct jobs “while bolstering the supply chain and manufacturing ecosystem” in the state.
“In Illinois, we aren’t just making electric vehicles: we are creating an entire ecosystem,” Pritzker said in a statement.
A subset of Rivian’s suppliers will complete light assembly and manufacturing at the new 1.2 million-square-foot site. Then, to accelerate output, the parts will be moved to Rivian’s main plant through an underground tunnel connecting the two.

Construction is slated to be completed in 2026. Rivian’s CEO, RJ Scaringe, said the new supplier park will be “a key enabler to increasing production” when the company launches its midsize R2.
The state of Illinois is offering Rivian a $16 incentive package to offset some of the upfront costs, including a $5 million Reimagining Energy and Vehicles (REV Illinois) tax incentive over 20 years.

Rivian said the new supplier park will also help boost production of its current EVs, the R1S, R1T, and Commercial Van, all built in Illinois.
In addition to the new supplier park, Rivian is upgrading its manufacturing plant with a 1.1 million-square-foot expansion to prepare for R2. Once the upgrades are complete, Rivian expects an annual production capacity of around 215,000 vehicles, up from 150,000.

Rivian said R2 is still on track to launch in 2026. It will start at around $45,000, or nearly half its current R1S and R1T.
Rivian plans to open its new plant in Georgia in 2028. Once up and running, it’s expected to increase annual vehicle production capacity to around 400,000 units.
As it upgrades the facility, Rivian expects fewer vehicle deliveries. After delivering 8,640 vehicles in the first quarter, the company reaffirmed plans to deliver between 46,000 and 51,000 in 2025.
