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.
