Sam Calisch Thinks Your Next Stove Should Have a Battery

After earning a PhD from MIT, Sam Calisch spent much of the past decade advocating for electrification and shaping climate policy as a lobbyist. His efforts included helping start Rewiring America, an organization focused on electrifying homes, businesses, and communities, as well as co-writing Electrify, a book about electrification, and a series called Circuit Breakers on the same topic.

But his work as a lobbyist revealed gaps in the market. “We were at a point where we no longer need huge, science project-type ideas,” Sam said. “What we need now are products that help deploy the amazing technologies we already have—solar, wind, batteries—faster and cheaper.”

This realization led him to explore creating a company to address those gaps. In 2020, he co-founded Copper, a company with a mission to transform how we cook and power our homes, starting with its flagship product: an induction stove with a built-in battery.

According to Sam, Copper was born to address a key adoption barrier: the high cost of electrical upgrades required for induction stoves. “People were spending more on rewiring their homes than on the stove itself,” Sam explained in an interview with The Spoon. His solution—a battery-integrated induction stove—allows users to plug into existing outlets, eliminating the need for costly electrical work.

But the battery wasn’t just a workaround—Sam believes it makes for a superior stove. “When you put a battery in a stove, it makes it a much better stove,” he said. “It’s silent, thanks to DC induction, and has enough power to preheat the oven in just four or five minutes. You can cook faster and more precisely than ever before.”

After securing a Department of Energy grant and venture funding, Sam and his co-founders began developing an early prototype. The first versions, however, weren’t exactly polished. “The first one I built, I lovingly call the shopping cart,” Sam said. “It was a set of rolling wire shelves with the components strapped on. I was so proud of it, but when I sent pictures to some folks in the industry, they couldn’t quite see the vision.”

Since then, Copper has come a long way. The company now assembles its stoves in California and primarily sells them in New York and California, with plans to expand. “We’re scaling manufacturing and doing deliveries every day,” Sam said. “It’s inspiring to see people switch to our product and love cooking on it.”

Beyond cooking, Copper’s stoves could play a larger role in energy management. The built-in battery allows users to store renewable energy and use it during peak times, reducing reliance on the grid. “It’s a powerful tool,” Sam explained. “You can charge the battery with solar power during the day and cook with it at night. It’s about giving people agency over how and when they use energy.”

Looking ahead, Copper plans to launch more appliances that bridge the gap between sustainability and performance. “Look around your house—especially at the appliances that use gas today,” Sam said. “We’ve got exciting projects in the works.”

For Sam Calisch, Copper isn’t just about selling stoves—it’s about transforming how people think about electrification. “We want to make switching easy and show the best versions of what’s possible,” he said.

Why a Small Startup in the Middle of Valencia May Be Leading the Wireless Energy & Invisible Cooktop Trend

About a decade ago, IKEA famously released a concept video laying out its vision for the kitchen of the future. The central concept for their envisioned future kitchen was a kitchen table that not only made the experience of cooking and eating interactive with a touch interface, but also had built-in induction transmitters under the table’s surface that transmitted energy to power appliances and powered invisible-to-the-eye heating zones.

It was a compelling peek into what could be. While induction cooktop hob technology was and is a somewhat mature technology, the idea of using an induction transmitter to provide both wireless power and heating in everyday kitchen countertop surfaces fired up our imaginations in the same way Tom Cruise’s John Anderton character did about gesture interfaces more than two decades ago in Minority Report.

Since IKEA released its video, the futuristic idea of using an ordinary surface as a source of power and cooking heat has been inching slowly toward becoming a reality without ever seeming to make it to market. While there have been some efforts in standards-building by the same organization that brought us wireless phone charging standard Qi, actual product introductions of kitchen surfaces with built-in wireless power and heating have been pretty much non-existent.

But that’s changed over the twelve months thanks to a company named Cloen. Nestled on the east coast of the Iberian peninsula, this small Spanish startup has begun to pull back the curtain on the technology they’ve been developing for the better part of a decade. The company’s technology, which it calls Cloen Cordless Technology (CCT), is built around a dual induction plate system that provides heating to cook zones and wireless energy transmission to countertop appliances.

The company’s patented technology is on display in New York City at the flagship showroom of Spanish tile maker Porcelanosa. For Porcelanosa, another (and much older) company that also makes its home in the Valencian Community of Spain, Cloen built a custom-designed set of kitchen countertops and furniture with the CCT technology under the Spanish tile and furniture company’s Gamadecor brand.

You can watch a demo video of the CCT-powered Gamadecor product below:

In addition to building their own countertop kitchen products and those of partners (like Porcelanosa) with built-in transmission systems, Cloen is also working on a new line of countertop small appliances under the BeCordless brand, a joint venture between Cloen and cookware company Bergner. These countertop cooking appliances, which you can see in usage in the video above, include blenders, toasters, and air fryers.

The company is working with Porcelanosa on the cooking surface roadmap to build modular kitchen cooktops with up to five invisible cooking and power transmission zones. It also works with other manufacturers to build kitchen tables with dual-cooking and power transmission zones.

The company has also worked with TV show producers in Spain and South Korea to build custom products for chef-centric cooking programs. In fact, you can see the Cloen-powered cooktop on Netflix in the reality TV show Lady Tamara, which is about Spanish aristocrat and chef Tamara Falcó.

For its product in Korea, the company is developing a table similar to the one in the IKEA concept video. However, if you expect to cook on a wood-only kitchen table, you might be slightly disappointed. According to Cloen, the table will have both power zones on the wood surface and induction heating in an in-laid glass area.

The company, which was founded by Pablo Cerra, an engineer by training, has grown to around 20 people, over half of them engineers. The focus on engineering is due to Cerra’s intention of building everything needed for the system. Cloen owns not only the core technology concepts but also develops the software and provides the SoC circuit boards to build into its partners’ systems.

“The secret is the software algorithm and the chip (microprocessor),” Cerra told The Spoon. “That’s secret to the whole technology.”

Cerra and his team decided to build a full-stack company to be an ingredient technology for their own and other brands’ wireless power kitchen technology because he felt the foundation needed to be laid for the market.

“This technology has to be for everyone,” Cerra said. “If you buy a mobile phone now, you can charge it with a normal charger or wireless charging. The thing is, wireless power and induction for the kitchen have to be the same.”

But Cloen isn’t alone. As mentioned, the Wireless Power Consortium is working on its Ki standard, and we’ve heard from multiple appliance brands that they are investigating and actively building products that will include wireless power. Other startups and tile companies are also looking at building wireless power systems.

Stepping back, the arrival of wireless power and invisible cooking zones is also part of a broader trend towards technology and functionality in the kitchen receding into the background. Sure, it’s part of the invisible kitchen design trend, but it’s also bigger than that, part of the megatrend that has technology disappearing before our eyes, fueled by AI, voice and gesture interface platforms, technology miniaturization, and the influence of companies like Apple and, well, IKEA over the past decade.

Can Whirlpool’s Deal to Use BORA’s Downdraft Ventilation Add Momentum to Induction in the US?

One of the more intriguing long-term technology trends in the kitchen industry has been the up-and-down market evolution of induction cooking. Though introduced almost a century ago at the 1933 Chicago World’s Fair, residential induction cooktops only became widely available in the early 2000s and have never really taken off here in the States due to, among other things, America’s love affair with gas cooking.

There are other factors – like the requirement for new cookware with induction cooking and the technology’s historically higher price point – but the bottom line is gas has long enjoyed pole position in American homes and on appliance show floors across the US.

However, induction cooking has slowly but surely been gaining ground over the past couple of years. Lower prices, health benefits, and local government building restrictions have given the technology momentum.

And now, at least if you’re Whirlpool, induction cooktop may have another ace up its sleeve in the form of downdraft ventilation. That’s because the appliance giant announced today they’ve teamed up with downdraft ventilation specialist BORA to bring the German company’s technology to the US market. From an article I wrote for Forbes (ed note: where I’ve long been a contributor and the publication Whirlpool agreed to an exclusive):

By adding downdraft technology, Whirlpool hopes to capitalize on the growing popularity of a venting technology that does away with the traditional vent hood and puts additional wind at the back of induction cooking here in the US. Reviews for downdraft ventilation, which like induction has taken off faster in Europe, have been mixed, but gradual improvements in the technology have caused some to give it a second look.

For BORA, the deal marks the first time the company has agreed to license the technology to an external company.

“This is the first time since the beginning of BORA that I have given away the right for the technology,” Willi Bruckbauer, company founder, told me in an interview. “I founded the company in the year 2007. More and more people liked the idea, like the product, and now it’s ready to go from Europe to the US.”

For much of its life, reviews for downdraft technology have been pretty mixed. Clogged filters and an inability to capture all smoke and cooking smells have been top complaints. However, BORA’s patented technology has been earning rave reviews in the European market, so Whirlpool may just have locked up a deal that could help it create separation from other kitchen brands that already have downdraft technology for their gas cooktops and are planning rollouts of downdraft technology with induction cooktop models.

And let’s be honest: kitchen hoods, while effective, often obstruct views and seem out of place in kitchen islands. And, with kitchen islands making a comeback as more home designers and kitchen remodelers are opting for open designs lately, the timing for this partnership seems especially good for Whirlpool.

According to Whirlpool, they are slotting the rollout of the BORA-powered downdraft technology in its JennAir and KitchenAid brands in the second half of 2025. By combining what some see as the world’s leading downdraft technology exclusively with its induction cooktops, Whirlpool could set itself up for additional momentum for its induction models and help drive interest in the electrified cooking technology in the US market.

Silicon Valley is Betting Big on Home Electrification. Will It Pay Off In The Kitchen?

This week, news of a new home electrification startup hit the wires.

Founded by former Google Ventures partner Rick Klau, Onsemble builds technology to convert electric water heaters into what the energy industry calls a virtual power plant (VPP). VPPs act as aggregators and coordinate between independent distributed energy resources (DERs), such as rooftop solar and electric vehicles, with the electric grid. While Onsemble won’t enable water heaters to generate energy like a solar panel on your roof, the company believes that connecting and coordinating your water heater with the grid will translate to significant savings.

It’s an interesting concept, one that is symbolic of a growing interest within Silicon Valley and the broader technology community around home electrification. This interest has been rising for years, especially in markets like California, where state and local governments have pushed regulations around the construction of residential and commercial buildings mandating electrification. But it goes beyond that, and much of the recent flurry of activity has been spurred by a flood of new money entering the market through rebates that are part of the Inflation Reduction Act.

Other startups that have ridden the home electrification wave over the past couple of years include Zero Homes, which partners with local municipalities to prove a decarbonization pathway roadmap for home electric users to help guide them towards home electrification. Another is QuitCarbon, which provides Bay Area customers with electrification roadmaps that outline the types of electric appliances for their home’s specific electricity infrastructure and help consumers navigate the home rebate process. Similarly, Elephant Energy partners with contractors to help install indication ranges, car EV charging stations, and heat pumps.

And then there’s Impulse Labs, a startup creating induction cooktops that incorporate a battery to help consumers transition to electric kitchens. By including a battery will enable those homes that aren’t wired for an induction cooktop – electric stoves can pull 40 amps at 240 volts after all – enables the homeowner to use one without having to rewire their homes or install a new electric panel. Impulse’s energy-storing cooktops will also serve as another energy storage node – or DER – on the electric grid’s network that can contribute to the collective VPP.

Of all the ideas, Impulse’s strikes me as the most innovative; it provides a solution that is not only about installation planning or falling in line with local building codes, but is an altogether new approach that helps both homeowners and the utility provider by putting a new kind of system (in the package of a conventional appliance) into the network.

There’s no doubt we’ll need more of these approaches as US homeowners, in particular, struggle to sever their strong addiction to gas heating and cooking. The installed base of gas stoves in the U.S. is massive, and there are significant financial and emotional attachments to cooking with fire. By embracing truly new alternatives that offer real benefits (financial and lifestyle), the kitchen electrification movement might actually stand a fighting chance

As Political Fight to Ban Natural Gas Rages On, Microsoft and Others are Pressing Ahead With All-Electric Kitchens

If you’ve paid attention to natural gas regulation over the past few years, you’re probably aware a growing number of municipalities and state governments have pushed to ban the use of the gas hookups in new home and office builds as they look for ways to cut back on greenhouse gas emissions.

It started with Berkeley in 2019, and since that time, a number of cities in California and New York have followed suit with efforts to restrict or outright ban the use of natural gas. Predictably, GOP-controlled legislatures around the country have fought back by passing “preemption laws” that prohibit cities from banning natural gas. According to CNN, twenty states with GOP-controlled legislatures have preemption laws prohibiting cities from banning natural gas.

But while the political battle between old-world gas adherents and those looking to reduce our reliance on gas rages on, big companies like Microsoft are reading the tea leaves and building electric kitchens. According to a story in Fast Company, the software giant is building an all-electric kitchen in one of its newest buildings in Redmond, Washington.

From Fast Company:

It’s a 13,000-square-foot LEED Platinum-rated green building, with 400 pieces of electric kitchen equipment capable of preparing about 1,000 meals a day across 9 dining concepts featuring different cuisines. The space is being used to test out products, processes, and menu items before spreading to more than 77,000 square feet of food preparation and kitchen space for upward of 10,000 meals a day when the full campus expansion begins opening in 2023.

Microsoft is just the latest company to start transitioning its office space – and its kitchens – to all-electric as they see the writing on the wall when it comes to local mandates. In 2020, Adobe broke ground on an 18-story all-electric building for its new headquarters. Alloy Development started development in 2020 on a five building all-electric project.

The reason for these moves is clear. According to the Building Decarbonization Coalition, gas combustion in buildings accounts for more greenhouse gas emissions (12%) than all in-state power plants (9%), so by moving towards all-electric buildings, companies can make a significant dent in meeting sustainability targets.

As for Microsoft, the effort includes designing new types of cooking equipment that can meet the needs of feeding their workforce. The company wanted to continue creating a variety of different kinds of menus, including ones that traditionally utilize fire-intensive cooking styles such as woks, so they worked with an outside designer to develop an induction wok cooking system.

Fast Company: To figure out a solution, Microsoft partnered with the commercial kitchen equipment manufacturer Jade Range. Over the course of two years they co-developed a new kind of wok-cooktop combination that allows both the motion a chef needs and the constant contact induction cooking requires. The novel wok system, with a pan that fits inside a bowl-shaped cooking surface, has stood up to side-by-side taste tests among Microsoft workers, comparing gas and induction wok dishes. 

While the U.S. has long trailed Europe in its use of induction cooking, the push for building electrification has given increased momentum and has started to force the hand of many hold-outs who have long preferred gas cooking equipment.
