Micro-Gap Thermal Diode

A passive component that controls the direction of heat flow, no fans, no fluids, no power. Envisioned for electronics, data centers, and spacecraft within 10–20 years. The physics has been proven experimentally in a home laboratory. Results measured. Physics confirmed.

"We didn't just theorize it, we proved the physics experimentally."

Every electronic device, every data center, every building wastes energy fighting heat. We proved the physics of a device that stops the fight.

The Problem

Global cooling systems, fans, pumps, and HVAC loops consume trillions of watts fighting heat that has no preferred direction. Data centers alone spend 30 - 40% of their power just on cooling. The MGTD gives heat a direction. Passively. Permanently. Without power.

Heat flows indiscriminately

The Physics

At gaps smaller than 10 micrometers, electromagnetic waves tunnel heat across space — and the direction of that transfer depends on which material faces the hot side.

Direction-dependent at µm scale

The Proof

We built a precision thermal apparatus, ran overnight experiments under partial vacuum, and measured 6.7% thermal rectification — statistically significant at

p < 0.001.
