Thermal Infrastructure for Space Compute

Cooling is the bottleneck.Nuwatts is the fix.

AI in space is limited by heat, not power. Nuwatts reduces radiator burden by preserving temperature in transport and recovering part of waste heat into useful energy.

Cooling, Not Power, Limits Space Compute

In space, heat cannot be removed through convection. Every watt must be transported to a radiator and radiated away. That single constraint drives radiator area, deployables, pointing requirements, and reliability.

A New Thermal Architecture

Nuwatts treats heat as a resource, not just a burden. By combining efficient heat transport with energy recovery, we reduce the amount of heat that must ultimately be radiated away.

Move Heat Efficiently

Preserve temperature through transport so the radiator can operate hotter and reject more heat per square meter.

Recover Energy

Turn a portion of waste heat back into useful electrical value instead of forcing every watt to the radiator.

Reduce Radiator Burden

Less heat to reject means less radiator area, lower mass, simpler integration, and more room for compute.

Every Degree Matters

Radiator performance scales with temperature to the fourth power. Small losses in thermal transport can dramatically increase required radiator area.

Why every degree matters
Reference case
Chip max temp85°C
Transport drop15°C
Radiator temp70°C
Reference heat load100,000 kW
~3,000 m²
radiator area saved per 1°C recovered in a 100 MW system
The important takeaway is not just efficiency. It is geometry. Preserve temperature in transport and the same heat can be rejected with materially less radiator area.

Built for the Next Generation of Compute

The near-term wedge is terrestrial data centers. The long-term upside is space compute, where thermal constraints define the hardware envelope.

Application

Space Compute

Orbital data centers, satellite payloads, edge compute in orbit, and future high-density spacecraft platforms.

Application

Data Centers

A near-term proving ground with measurable cooling pain, clearer ROI, and a practical path to first deployment.

Not a Component. A System Layer.

This is the clearest competitive framing: others optimize components. Nuwatts optimizes the thermal system.

Alternative

Incumbent Cooling Vendors

Move heat, then reject it. Complexity scales with power and radiator burden remains.

Alternative

Commodity Thermoelectrics

Convert heat, but do not solve transport or system-level thermal bottlenecks.

System layer

Nuwatts

Move heat, recover energy, and reduce radiator area in one integrated thermal architecture.
