With its new miniaturized Mac Mini, Apple has a second product — and its first Mac — that qualifies for its “carbon neutral” label. As part of the push, the company is buying enough renewable power to offset emissions generated from customer use of the computers.  Tech companies have been tracking, and in some cases

When people imagine what 3D printing is, they might think of plastic knickknacks and miniature figurines that teenagers make in their high school libraries. For HILOS (Human Innovation Lab Operating System), 3D printing means creating footwear that’s chic, low-waste, and runway ready.  “Brands are overproducing 20% because they don’t know what size and styles are

Eight years ago, Brian Garrett and his partners sensed the ground shifting.  At the time, Crosscut Ventures, where Garrett is co-founder and managing partner, had been investing in early stage startups in Los Angeles and Southern California for nearly a decade. It focused mostly on software companies, but it started shifting its attention to hardware,

Fixing the climate crisis is a vast, world-sized puzzle. But one particularly large piece of this ginormous conundrum is construction and real estate — which collectively amount for around 40% of global greenhouse gas emissions. Enter Munich-based data startup Emidat, which has built a software platform for automating the generation of validated Environmental Product Declaration

Many startups have taken aim at the problem of early wildfire detection and prevention, but Turkey-based ForestGuard’s space-based system could give it an edge over competitors. ForestGuard, which presented onstage today as part of the Startup Battlefield at TechCrunch Disrupt, was founded by trained architects Muhammed Ali Örnek and Suat Batuhan Esirger, who witnessed the need for early

If there’s anything that came from one of the worlds that was promised to us in “Back to the Future” or “The Jetsons” or innumerable other sci-fi franchises, it’s what SpiralWave co-founder and CEO Abed Bukhari showed me on a video call. Purple-tinged waves of white plasma rhythmically rose and vanished within a metal-screened column,

Ammonia may conjure thoughts of off odors, but the world is entirely dependent on the smelly stuff as a fertilizer and for use in myriad other industries. Problem is, nearly all the ammonia produced today is heavily dependent on fossil fuels. Making the compound releases more than 450 million metric tons of carbon dioxide every

Solar panels are just about everywhere. There’s a good chance one of your neighbors has them on their roof, as does the big box store down the street. As you drive there, you might see a field of them posted up alongside the road. With that kind of ubiquity, you’d be forgiven if you thought

Cement startup Furno will receive a $20 million grant from the Department of Energy, funds that will help the company build up to eight micro-kilns at a concrete plant in Chicago.  Chicago might not seem like the sort of place where cement is hard to come by. But with the nearest kiln 100 miles away,

As petrochemical plants and other emitters look to reduce emissions, they’re finding that sopping up and storing all the carbon dioxide they produce doesn’t come cheap. First they have to capture it, an energy-intensive process that requires specialized equipment. Then they have to transport it and stash it away, which can be tricky depending on

Phillip Man was burned out. He had founded a watch trading company with his flatmate, but the grind was wearing him down. “We did that for ten years,” Man said. “It’s very difficult to keep yourself motivated when you know the whole reason for your operation is to sell expensive stuff to wealthy people.” He

General Motors is working with Forge Nano, a materials science startup, to find new ways to enhance the performance and lifetime of electric vehicle battery cells.  The automaker’s investment arm, GM Ventures, on Wednesday injected $10 million into Forge Nano, which is developing a thin coating the startup says will help improve safety and increase

Amazon today became the latest big tech company to throw its weight behind nuclear power, joining Microsoft and Google, which both previously announced long-term promises to buy nuclear power from startups to power their data centers. The company revealed three deals, including an investment in startup X-Energy and two development agreements that aim to add

The U.S. is facing a shortage of electricians, with unfilled jobs in the field expected to grow by 11% per year over the next decade, according to the Bureau of Labor Statistics. But because prospective electricians in the U.S. typically need to log 8,000 hours before they can get their license, the shortage won’t ease

As calls for urgent climate action persist, technologies to help remove the heat-trapping greenhouse gases from the atmosphere are also emerging globally. In Africa, Octavia Carbon, a Direct Air Capture (DAC) startup is leading the efforts. Octavia, founded in Kenya two years ago, builds DAC machines that it uses to capture carbon, a greenhouse gas

Meet Storio, a French startup that’s focused on providing smart energy storage for commercial and industrial customers. Founded in 2023, the startup raised a €5 million seed round earlier this year (around $5.5 million at current exchange rates) and has signed its first client. Storio believes solar panels have a bright future. But the company

Google announced today that it has signed a deal with nuclear startup Kairos Power to build seven small reactors to supply electricity to its data centers. The agreement promises to add around 500 megawatts of carbon-free electricity at a time when energy demand for data centers and AI is surging. The new power plants are

It only took four phone calls for Sébastien Fiedorow to quit his job as a venture capitalist. The first one came from Marble, a startup studio based in Paris. They had a scientist looking for help founding a company that would remove carbon dioxide directly from the atmosphere — what experts call direct air capture, or

The data center industry is expanding rapidly to keep up with the flywheel growth of AI. While these data centers are necessary AI infrastructure, they store an AI company’s compute, they are expensive to build, seemingly more so to run, and they are a huge energy suck. Startups are looking to make data centers more

As hurricanes batter the Atlantic and Gulf coasts of the United States, many people’s livelihoods are on hold and they’re struggling to make ends meet. The FCC just decided that anyone affected by a natural disaster can get a break on broadband and mobile service; it’s not much, but every little bit counts. The Lifeline

It was the banana that did it. Brian O’Kelley, who had recently sold his previous startup, ad platform AppNexus, to AT&T for a reported $1.6 billion, was watching a lecture through MIT during COVID as part of a yearlong course on supply chain management. “There was this one slide in a lecture about the carbon

The synthetic biology and precision fermentation space is a hotbed of entrepreneurial activity these days. But it’s not every day you come across a startup that’s using genetic engineering to produce natural rubber — a substance that’s challenging to reproduce in a lab because of how long its polymer is. Paris-based baCta has a proof

For fusion power aficionados, hitting “breakeven” is something of a Holy Grail: the point at which a fusion reaction produces more power than was required to ignite it. Only one scientific experiment, at the National Ignition Facility, has accomplished that feat, and it took over a decade of tweaking the system to achieve the monumental

Startup employees often go on to found interesting ventures, basing their new work on the experience gained from their time building a company from scratch. But not all of those experiences are positive, and sometimes, a less-than-satisfactory exit can do more to fuel a founder’s fervor than anything else. In the case of Forward Earth’s

Mo Alkhadra spent years of his life figuring out how to remove troublesome materials like toxic lead and radioactive waste from water. But as he progressed along his doctorate studies at MIT, he realized that if he wanted to bring his technology to market, he’d need to do something other than build a better Brita.

Earlier this year, KoBold Metals found what might be one of the largest high-grade copper deposits of all time, with the potential to produce hundreds of thousands of metric tons per year, the company’s CEO said. Now, just eight months later, KoBold is close to raising over half a billion dollars. The funding should help
