Aether exists to re-architect the invisible infrastructure that powers the modern economy. The rapid growth of AI-driven hyperscale data centers and energy-intensive industrial systems such as aluminum smelting, chlor-alkali electrolyzers, and electric steelmaking is outpacing the limits of conventional power distribution, straining capacity and limiting how efficiently the world can scale.
We build superconducting systems that unlock trapped capacity by allowing power to move freely across congested corridors without thermal constraints. By eliminating resistive losses, our cables deliver energy with near-zero loss, no heating, no bottlenecks, and no wasted megawatts. The result is a high-density, sustainable power architecture capable of supporting AI infrastructure, electrified industry, and renewable integration at a scale that redefines what modern energy networks can achieve.
From yard to pod
Aether’s system is built around a novel superconducting conductor geometry integrated within a proprietary cryogenic enclosure, forming a cable designed for exceptionally high power throughput with minimal thermal loss. This architecture enables efficient, stable delivery of electricity through constrained environments, with integrated power conversion and control to align output with end-use requirements safely.
High-capacity HTS core integrated within an ultra-efficient cryostat enables transmission of tens to hundreds of kiloamperes with negligible line loss. Designed for demanding power corridors, whether supplying AI infrastructure, electrified industrial systems, renewable integration, or high-current grid and substation connections.
High-voltage AC systems require multiple conversion steps to connect sources and loads, introducing loss and complexity at scale. By enabling DC-based power architectures, our system reduces unnecessary conversions, simplifies internal power delivery, and supports more efficient integration of renewables and high-demand electrical loads.
To avoid reliance on continuous liquid nitrogen deliveries, the system incorporates an in-line cryogenerator that enables autonomous operation. When integrated with the cryostat, the additional electrical load is small relative to the overall efficiency gains. Excess cooling capacity can also be utilized to offset local cooling and HVAC requirements.
Vacuum, thermal, and electrical telemetry combined with software-based health analytics, enabling operators to identify developing faults before they impact operation.
System Level Gains
Aether enables multi-megawatt power delivery in corridors where copper becomes impractical, collapsing parallel feeders into a compact footprint and freeing up critical space. This allows denser, higher-power compute or industrial layouts and accelerates energization timelines, enabling campuses to scale capacity with fewer physical and schedule constraints.
Reducing distribution losses eliminates wasted energy and associated emissions. High-efficiency delivery improves the effective yield of renewable generation, lowers campus PUE by minimizing line heat, and reduces embodied carbon by avoiding copper-intensive parallel conductors and unnecessary power equipment.
By enabling substantially higher current through existing corridors, Aether helps unlock constrained renewable generation and supports DC-forward power architectures. Fewer intermediate conversion stages, simplified protection schemes, and right-sized storage integration enable resilient, low-carbon power networks that scale with demand rather than limiting it.

By eliminating resistance, the capabilities of a single cable are 10x
Revolutionized transport schemes are optimized for their end use, not transport
Reduced civil works and reduced hardware requirements means a faster time to market
Power delivery has become the primary constraint on scaling AI infrastructure and energy-intensive industrial systems. GPU-driven workloads are pushing rack power requirements beyond 500 kilowatts and toward 1 megawatt, while heavy industries such as aluminum smelting, chlor-alkali electrolyzers, and electric steelmaking operate on continuous DC currents ranging from tens to hundreds of kiloamperes. In both cases, traditional AC architectures and metallic conductors face fundamental physical limits. Rising current drives resistive losses, heat generation, conductor size, and routing complexity, inflating capital cost, consuming space, and slowing deployment timelines.
The impact is already visible at scale. Global data center electricity consumption is projected to more than double over the next five years, reaching approximately 945 terawatt-hours per year by 2030, while industrial electrification continues to expand high-current DC backbones. Individual facilities now operate at 200–500 megawatts, with some projects planned at the multi-gigawatt level. Even as operators adopt 800-volt DC to reduce conversion losses, the transmission layer itself remains constrained by thermal limits, parallel conductor runs, and inefficient internal distribution. Power delivery has shifted from a supporting function to the defining bottleneck for growth.
Aether redefines internal power delivery by introducing a superconducting transmission layer designed for extreme power density and continuous operation. Rather than optimizing legacy AC systems, Aether replaces loss-intensive metallic conductors with superconducting DC cables capable of carrying orders of magnitude higher current with near-zero resistive loss and minimal heat generation. This enables a step change in power density, routing flexibility, and usable delivered power across both AI facilities and high-current industrial environments.
By removing the thermal and physical barriers inherent to conventional conductors, Aether transforms power delivery from a limiting factor into an enabling layer. The architecture supports high-voltage DC systems while eliminating the need for oversized conductors, dense parallel runs, and excessive thermal management. The result is a scalable, high-efficiency transmission backbone that allows AI data centers and electrified industrial facilities to expand reliably, efficiently, and without the physical bottlenecks that define today’s infrastructure.

Aether works on next-generation power delivery architectures for environments where conventional systems hit physical limits. Our focus is on system-level design, validation, and pathways to scale in data center and industrial settings.
We focus on first-principles constraints rather than incremental optimization. Instead of improving legacy architectures at the margin, we study and develop fundamentally different approaches where losses, thermal limits, and footprint no longer scale linearly.
Aether is in an advanced technical validation phase. We have completed internal modeling and are working through external validation and pilot pathways with research and industry partners.
