How it works
Bolt on. Capture. Convert. Spend it when it counts.
Put a temperature difference across the right solid-state material and it pushes out electric current. That's the Seebeck effect, and it's the whole engine: hot exhaust on one side, cooler air on the other, electricity in between.
Step by step
From wasted heat to power you can spend
-
Step 01
Capture
We mount where your exhaust heat is most concentrated. It plugs into the waste stream you already have, so there's no rebuild.
-
Step 02
Convert
Solid-state cells turn the temperature difference between hot exhaust and the surrounding air straight into DC electricity. No turbine, no fluid, nothing spinning.
-
Step 03
Store
Proprietary integrated storage banks the power while the kitchen runs, from morning prep to last order.
-
Step 04
Spend it when it counts
Use it on your schedule: the dinner rush and peak-rate hours, when the electric bill actually hurts.
- Solid-state

- Bolt-on install
- Integrated storage
Why it hasn't been done
So why does nobody catch it?
Because the usual heat-recovery machines weren't built for a kitchen. They were built for power plants and factories, and they come with the moving parts to prove it.
-
Wrong heat
Steam turbines
Need very hot exhaust: think furnaces, not fryers. Big, expensive and built for heavy industry.
-
Too much machine
Organic Rankine cycle
Can run on cooler heat, but bring a turbine, pumps and a working fluid. Expensive, complicated, more to break.

Built for this
Electofusion
Solid-state: no turbine, no pumps, no fluid. Built for low-grade heat, 150°F and up, and small enough to bolt onto a kitchen.
Power you can't use when you need it is just a discount.
The kitchen makes the power all day, the battery holds it, and the restaurant spends it when it counts. That changes the math.
Straight answer
What it won't do
It won't power your whole building. Electofusion recovers a portion of energy you were already paying to throw away, and every watt of it is one you don't pay for twice.
How much, exactly? We're measuring that on a real meter in a real kitchen, and we'll publish what it shows.

The short answers
What is Electofusion?
A solid-state system from The Heat Exchange Corporation that captures low-grade waste heat, 150°F and up, and converts a portion of it directly into electricity on site. No turbines, no pumps, no moving parts.
How does heat turn into electricity?
Through the Seebeck effect. When one side of a thermoelectric material is hot and the other side is cooler, it produces a direct current. Electofusion cells sit between hot exhaust and the air around it.
How hot does the heat need to be?
150°F and up. That's the air coming out of a typical kitchen exhaust hood, a dish machine or a refrigeration condenser: exactly the heat older recovery systems can't use.
Why pair it with storage?
Because power you can't use when you need it is just a discount. Equipment makes heat whenever it runs, not when your bill is highest. Storage holds the power so it gets spent at the dinner rush and peak-rate hours instead of being sold back to the grid for pennies.
What does it need in the way of maintenance?
Nothing spins, pumps or burns: there's no turbine, no working fluid and no moving part to wear out the way a mechanical system does. That's the point of going solid-state.
Will it power a whole building?
No. It recovers a portion of the energy you were already paying to throw away. How big that portion is depends on the site, and we're measuring it on a real meter at our own cafe first.
See the cafe demoIs it proven?
Small-cell tests are done, and the full demonstration is going into a working Louisville kitchen. The first meter numbers will be published on the cafe page, good or bad.
