CleanTech Talk — Solar, Batteries, EVs, AI Battery-Equipped Induction: A New Path to Clean Home Electrification
5 snips
Mar 24, 2026 Sam Calisch, engineer and founder/CEO of Copper, builds plug-in, battery-equipped induction stoves to make clean cooking accessible. He explains why induction matters and how pairing batteries avoids costly electrical upgrades. Sam describes simple 120V installs, benefits for renters and affordable housing, and real-world retrofits already underway.

Episode notes
Electrical Capacity, Not Taste, Blocks Induction Adoption
- Residential electrical capacity, not consumer preference, is the main barrier to induction adoption in the U.S.
- Stoves draw very high instantaneous power (similar to large EV chargers) and typically run at peak evening demand, creating upgrade costs.
Battery Paired Stoves Turn A Construction Job Into An Appliance Swap
- Pairing an induction stove with a modest battery lets it run from a standard 120V outlet and avoids costly electrical upgrades.
- Copper's analysis showed cooking uses high power for short durations, so a small battery can supply peak power on demand.
Deploy Storage At The Appliance Level To Cut Soft Costs
- Use lower-cost, appliance-integrated batteries to deploy storage widely and cheaply instead of relying solely on whole-home systems.
- Copper cuts soft costs (permits, custom work) and approaches raw battery hardware prices close to $100/kWh.
