At CES 2026 in January, a laptop sat on a wooden desk with no power cable plugged in, no charging pad beneath it, and no visible connection to anything. It was running, and it was charging. The company behind the demo, Etherdyne Technologies, says its system beamed up to 50 watts of power through the air to that laptop and several peripherals at the same time. Across the country, a University of Washington lab has demonstrated something arguably stranger: a laser that delivers usable electricity to a phone from meters away, shutting off instantly if a hand crosses the beam. Two very different bets on the same idea. Neither has shipped a product. But both have working hardware, and both are forcing the same question: is the power cable’s days finally numbered?
What Etherdyne showed at CES 2026
Etherdyne’s demonstration centered on what the company calls a 3D Power Zone, a defined volume of space where devices receive energy transmitted through low-frequency magnetic resonance. According to the company’s press release, the system powered a cord-free desk setup at up to 50 watts, charging a laptop alongside peripherals like a mouse and keyboard. The core claim: devices do not need to sit on a specific spot or align with a coil. They just need to be inside the zone.
The physics relies on coupling energy between a transmitter coil embedded in or near the desk and smaller receiver coils built into each device. Magnetic fields pass through wood, plastic, and fabric without much trouble, so the system can work through a desk surface or across a short gap of open air. The trade-off is distance. Magnetic resonance weakens sharply as the gap between transmitter and receiver grows, which is why Etherdyne’s Power Zone is measured in desk-scale dimensions, not room-scale ones.
Etherdyne frames this as a meaningful leap beyond the Qi wireless charging pads most people know from smartphones. Where Qi requires near-contact placement on a specific spot, the 3D Power Zone is described as more like an invisible bubble. A laptop could charge while being slid around the desk. A webcam or speaker could run without its own power cable. The company says the system handles multiple devices at once without manual switching or pairing, though CES demos are controlled environments, and booth conditions rarely mirror the clutter and variability of a real office desk.
Etherdyne is a member of the AirFuel Alliance, an industry group that promotes resonant wireless charging standards as an alternative to Qi. That affiliation matters because it suggests the company is working within a broader ecosystem rather than building a fully proprietary island, which could affect how quickly device makers adopt compatible receivers.
The laser approach from the University of Washington
The UW team took the opposite engineering bet. Their prototype uses a narrow infrared laser beam aimed at a small photovoltaic cell on the receiving device, converting light back into electricity. The result: multi-watt power delivery across several meters, enough to charge a smartphone from across a room.
The obvious concern with any exposed laser beam is safety. The UW researchers built an automatic shutoff mechanism directly into the system’s architecture. The beam kills itself the instant anything, a hand, a pet, a coffee mug, crosses its path. The transmitter also scans for a compatible receiver and confirms the target before sending power, using additional hardware to continuously monitor the beam path for obstructions. The researchers have emphasized that this safety interlock is fundamental to the design, not bolted on afterward.
The UW work, which the team first publicized around 2021 to 2023 through the university’s institutional channels, demonstrates that a laser can deliver usable power across a room while staying within human exposure limits, at least under controlled lab conditions. It is important to note that the publicly available descriptions from the university provide general results and safety details but stop short of a comprehensive peer-reviewed journal publication with full reproducible methodology. It is a proof of concept with real hardware behind it, not a simulation or a paper study, though the limited public documentation means some technical specifics remain difficult for outside experts to independently verify.
The contrast between the two approaches is stark. Etherdyne bets on magnetic fields that fill a small zone and work regardless of obstacles between transmitter and receiver, as long as everything stays within a short range. The UW team bets on focused optical energy that can cross a large room but demands a clear line of sight. Both have produced functioning prototypes. Neither has announced a commercial product.
The gaps that still matter
The biggest gap in the Etherdyne story is independent verification. The 50-watt figure and the position-free charging claim come entirely from the company’s own press materials, distributed through PR Newswire. No third-party test lab, trade publication teardown, or peer-reviewed paper has confirmed those numbers as of June 2026. Transferring 50 watts wirelessly through open air at desk scale would be a significant step beyond the 5 to 15 watts typical of Qi charging pads, and Etherdyne has not disclosed the system’s wall-to-device efficiency, meaning how much energy is lost as heat in the process.
The UW laser project carries more academic credibility because it originates from a university engineering department and includes descriptions of the safety mechanism and general power-delivery results. But the publicly available documentation stops short of a full peer-reviewed journal paper with reproducible methodology for the multi-meter, multi-watt claims. Whether the system can scale to laptop-class power levels, typically 30 watts or more for sustained use, is an open question the available research does not address.
Regulation looms over both approaches. Over-the-air power at meaningful wattages sits in a gray area between radio-frequency emissions rules and optical safety standards. For context, Energous, a separate company, received the first FCC Part 18 certification for over-the-air wireless power transmission with its WattUp PowerBridge transmitter, but that device operates at roughly 2 watts, a fraction of what a laptop needs. Regulatory approval for higher-wattage transmission remains largely uncharted in the United States. Neither Etherdyne nor the UW team has publicly disclosed FCC filing activity for their respective systems, though it is worth noting that some FCC applications can remain confidential during review.
Then there is efficiency, the persistent challenge for any wireless power system. Magnetic resonance loses energy as heat, and those losses grow with distance and misalignment between coils. Laser systems lose energy at the photovoltaic conversion step and face the hard constraint that any beam obstruction halts power delivery entirely, reducing effective throughput in busy environments. Neither team has published wall-to-device efficiency figures that would let engineers or consumers compare these methods against a USB-C cable, which delivers power with minimal loss over short distances.
Interference and coexistence raise additional questions. A desk-scale magnetic system must avoid coupling unwanted energy into nearby metal objects or sensitive electronics, which can cause heating or electromagnetic compatibility problems. A room-scale laser charger must coexist with ambient lighting, sensors, and other optical systems. Without detailed technical documentation from either team, outside experts cannot fully evaluate how these edge cases have been handled.
When any of this might actually reach a desk
For anyone wondering when they might buy a truly cordless desk, the honest picture is sobering. Neither Etherdyne nor the UW team has announced a ship date, a retail price, or a licensing deal with a laptop manufacturer. Etherdyne’s demo proves the concept works in a controlled booth. The UW project proves lasers can safely deliver power across a room in a lab. The distance between a trade-show prototype and a shipping product typically involves years of work on efficiency optimization, safety certification, thermal management, industrial design, and supply chain development.
The most plausible near-term path is that these technologies first appear in constrained settings: specialized industrial workstations, retail kiosks, or tightly controlled office environments where the geometry and device mix are known in advance. That would give engineers real-world performance data and regulators time to develop clear rules around continuous over-the-air power delivery at higher wattages.
What CES 2026 and the UW lab have established is that the underlying physics works and that safety mechanisms can be built in from the start. The power cable is not obsolete yet. But for the first time, the engineering required to make it obsolete is no longer theoretical. It is sitting on a desk in Las Vegas and firing across a lab in Seattle, waiting for the rest of the industry to catch up.
