The Best Ventless Fireplaces for Cozy Vibes (2025)

The Lloyd from Solo Stove pays serious homage to the freestanding mid-century enameled MCM Preway fireplaces that fetch thousands on the vintage marketplace. For less than $1,000 and a few minutes of assembly, the Lloyd may be a solution for those who want a real flicker. The Lloyd comes in five easy-to-love colors and most resembles the OG Malm Zircon. Made of electroplated steel, metal, and glass, the 31-pound Lloyd stands 3.5 feet tall. The Lloyd uses TerraFlame gel fuel, a proprietary blend

US Taxpayers Will Pay Billions in New Fossil Fuel Subsidies Thanks to the Big Beautiful Bill

The Trump administration has already added nearly $40 billion in new federal subsidies for oil, gas, and coal in 2025, a report released Tuesday finds, sending an additional $4 billion out the door each year for fossil fuels over the next decade. That new amount, created with the passage of the One Big Beautiful Bill Act this summer, adds on to $30.8 billion a year in preexisting subsidies for the fossil fuel industry. The report finds that the amount of public money the US will now spend on dom

America’s First Private Nuclear Fuel Recycling Facility to Open in Tennessee

Nuclear energy is among the most promising alternatives to fossil fuels—if we can find a sustainable way to take care of the unwanted, radioactive waste generated by the process. Stakeholders from both the public and private sectors have suggested various solutions, but a Tennessee firm will be the first to actually build and operate a U.S.-based recycling facility for nuclear fuel. In a statement last week, Oklo Inc. announced plans to build the first private nuclear fuel recycling facility in

This American nuclear company could help India’s thorium dream

“This license marks a turning point, not just for Clean Core but for the US-India civil nuclear partnership,” says Mehul Shah, the company's chief executive and founder. “It places thorium at the center of the global energy transformation.” Thorium has long been seen as a good alternative to uranium because it’s more abundant, produces both smaller amounts of long-lived radioactive waste and fewer byproducts with centuries-long half-lives, and reduces the risk that materials from the fuel cycle

Chinese astronauts make rocket fuel and oxygen in space

Astronauts on board China's Tiangong space station have created rocket fuel and oxygen from water and carbon dioxide, similar to how plant's photosynthesize. Chinese astronauts have just created rocket fuel and oxygen in space using a new type of "artificial photosynthesis." The breakthrough technology, which used fairly basic equipment and minimal energy, could one day be put to use on China's proposed moon base, which is scheduled to be completed within a decade. The new experiments were car

Why wind farms attract so much misinformation and conspiracy theory

When Donald Trump recently claimed, during what was supposed to be a press conference about a European Union trade deal, that wind turbines were a "con job" that drive whales "loco," kill birds and even people, he wasn’t just repeating old myths. He was tapping into a global pattern of conspiracy theories around renewable energy—particularly wind farms. (Trump calls them “windmills”—a climate denier trope.) Like 19th century fears that telephones would spread diseases, wind farm conspiracy theo

Engineering Breakthrough Opens Door to Cheap Hydrogen Power

As an alternative to fossil fuel combustion, hydrogen fuel cells hold tremendous promise. But they’re also notoriously difficult and expensive to manage, which largely explains why we don’t see them everywhere (or anywhere, for that matter, except for a few initiatives that are “exploring” their efficiency). But that may soon change. In a Nature Materials paper published August 8, researchers announced the development of a new type of solid-oxide fuel cell (SOFC) that addresses an underlying pr

SOSV bets plasma will change everything from semiconductors to spacecraft

Sometimes a tool — like a hammer — comes along and everything starts looking like a nail. But other times, new tools end up being more than a simple blunt-force object. The investors at SOSV are betting that plasma will become a nuanced implement capable of everything from enabling fusion power to changing the way semiconductors are made. It sees so much potential that it plans on investing in more than 25 plasma-related startups over the next five years. It is also opening a new Hax lab space

Another big car company gives up on hydrogen

Stellantis, the automotive giant behind Chrysler, Citroen, Fiat, Jeep and Peugeot, is pulling out of hydrogen. The company said it’s killing its fuel cell development program in the face of “limited availability of hydrogen refueling infrastructure, high capital requirements and the need for stronger consumer purchasing incentives.” To put that another way, it’s realized hydrogen EVs are facing the same set of challenges it’s not been able to overcome in the last two or three decades. It’s a st

Feds tell automakers to forget about paying fuel economy fines

Automakers selling cars in the United States now have even less incentive to care about fuel economy. As Ars has noted before, the current administration and its Republican allies in Congress have been working hard to undermine federal regulations meant to make our vehicle fleet more efficient. Some measures have been aimed at decreasing adoption of electric vehicles—for example the IRS clean vehicle tax credit will be eliminated at the end of September. Others have targeted federal fuel econom

Stellantis abandons hydrogen fuel cell development

To paraphrase Mean Girls, "stop trying to make hydrogen happen." For some years now, detractors of battery electric vehicles have held up hydrogen as a clean fuel panacea. That sometimes refers to hydrogen combustion engines, but more often, it's hydrogen fuel cell electric vehicles, or FCEVs. Both promise motoring with only water emitted from the vehicles' exhausts. It's just that hydrogen actually kinda sucks as a fuel, and automaker Stellantis announced today that it is ending the developmen

Nuclear Waste Reprocessing Gains Momentum in the U.S.

The United States’ 90,000-ton stockpile of radioactive nuclear waste has long been a liability, but researchers are increasingly eyeing it as a resource. New techniques in transforming spent fuel, new nuclear fuel cycle directives from the Trump administration, and the doling out of a Biden-era $40 million research program together aim to repurpose nuclear waste on a commercial scale. In a suite of executive orders announced on May 23, U.S. President Donald Trump directed the U.S. Department of

China jumps ahead in the race to achieve a new kind of reuse in space

Two Chinese satellites have rendezvoused with one another more than 20,000 miles above the Earth in what analysts believe is the first high-altitude attempt at orbital refueling. China's Shijian-21 and Shijian-25 satellites, known as SJ-21 and SJ-25 for short, likely docked together in geosynchronous orbit some time last week. This is the conclusion of multiple civilian satellite trackers using open source imagery showing the two satellites coming together, then becoming indistinguishable as a

GOP budget bill poised to crush renewable energy in the US

Far from the front lines of the climate crisis, 100 men and women in air-conditioned offices, 61 of them millionaires, are making decisions that could increase United States carbon dioxide emissions, and the warming of the climate they are driving, for decades to come. In the latest political wrangle over energy and climate policy, a group of Republican senators over the weekend added provisions to the U.S. federal budget bill that, as currently written, would end clean energy tax credits at th

Lamborghini Revuelto review: perfect harmony

With the dawning of a new era of hybridization in the automotive industry, more and more manufacturers are integrating electric propulsion into their lineups. Mild-hybrid systems are well-established, and more beneficial plug-in hybrid systems keep getting better and better. Even Lamborghini’s participating in the latest wave of hybridization, which might come as a surprise to some. That’s because this Italian company’s outlandish supercars have never been regarded as thrifty, or ever trying to

Biofuels Policy, a Mainstay of American Agriculture, a Failure for the Climate

The American Midwest is home to some of the richest, most productive farmland in the world, enabling its transformation into a vast corn- and soy-producing machine—a conversion spurred largely by decades-long policies that support the production of biofuels. But a new report takes a big swing at the ethanol orthodoxy of American agriculture, criticizing the industry for causing economic and social imbalances across rural communities and saying that the expansion of biofuels will increase greenh
