At a moment when solar farms are being built faster than grids can absorb their daytime peaks, a California startup is betting that the next big upgrade will not be on the ground at all, but in orbit. Instead of adding more panels, it wants to use lasers in space to send clean electricity back to Earth at night, turning the sky into an always-on power plant.
The idea, long relegated to science fiction, is now drawing real hardware, real money, and real scrutiny, as a small U.S. firm races to prove that beaming energy from orbit can be safe, efficient, and commercially useful before rivals lock in other approaches.
A new kind of space power play
I see the core of this story as a shift in how we think about solar itself, from something that must live on rooftops and deserts to something that can be harvested in orbit and delivered on demand. The company at the center of that shift, Aetherflux, is building satellites that collect sunlight in space, convert it into electricity, and then fire that power down to the surface as tightly controlled laser beams aimed at compact receiving stations on the ground. Instead of blanketing acres with panels, its approach focuses on concentrating energy into smaller spots on the ground that can feed local grids or microgrids.
That basic architecture, often grouped under the banner of space-based solar power, or SBSP, is not new, but the way Aetherflux is packaging it is. The firm is positioning its system as a way to turn intermittent renewables into something closer to a dispatchable resource, with satellites orbiting above the clouds and the weather, and lasers that can be switched on when demand spikes after dark. In the broader landscape of Space-to-Earth power startups, that emphasis on controllable beams and compact receivers is what makes the company stand out.
From trading app fortune to orbital energy bet
Behind the technical ambition sits a founder with an unusually public profile and a very specific number in mind. Robinhood Co executive and co-creator of the trading app used by millions of retail investors has turned his attention to orbit, with Robinhood Co Founder Baiju Bhatt Launches a Space Solar Bet To Beam Energy From Orbit, Eyes a Demo In Sci that is explicitly framed as a leap from fintech into hard infrastructure. The new company, Aetherflux, is his vehicle for turning that fortune into hardware that can move electrons instead of equities.
That pivot is backed by serious capital, not just a hobbyist’s curiosity. Armed with a Series round of $50 m, billionaire Baiju Bhatt is described as using a $50 million war chest to move from Wal Street success into orbital energy, a figure that matches the $50 million that The California startup, launched by Baiju Bh, has secured from investors. That level of funding, especially at this early stage, signals that backers are treating space power not as a distant dream but as a near-term infrastructure play.
How laser-beamed solar from orbit actually works
To understand what is at stake, I find it useful to walk through the physics and engineering that Aetherflux is trying to tame. In orbit, the company’s satellites would deploy solar arrays that sit above the atmosphere, where sunlight is more intense and uninterrupted by clouds or night. Onboard electronics convert that solar energy into electricity, then into coherent light, which is fired as a laser toward a precisely aligned receiver on the ground. The company’s own description of its Power Beaming Space concept emphasizes that the goal is to send energy where it is needed most, rather than where the sun happens to be shining.
On the surface, those beams are captured by photovoltaic or thermal receivers that turn the incoming light back into electricity, which can then be fed into local grids, batteries, or even directly into critical loads. Aetherflux’s published Technology plans describe a constellation of satellites that collect solar energy in space via solar panels, distribute that power among spacecraft, and then focus it into small, high-intensity spots on the ground, potentially even smaller than that, which is a very different footprint from sprawling terrestrial solar farms.
Why aim lasers at solar farms at night
The counterintuitive twist in Aetherflux’s pitch is that it does not want to replace ground-based solar, it wants to feed it after dark. By targeting existing solar farms with its beams, the company can use the same inverters, transformers, and grid interconnections that already exist, effectively turning those sites into 24-hour clean power hubs. In that model, the panels soak up sunlight during the day, then the same land and grid tie-ins receive laser-delivered energy at night, smoothing out the peaks and valleys that now force grid operators to curtail solar output or fire up gas plants when the sun goes down.
That strategy also helps explain why the company is initially focusing on specific, high-value use cases rather than trying to displace entire national grids overnight. Reporting on the firm’s early roadmap notes that the company is initially targeting defense applications, such as forward operating bases where “the supply chain and ge…” are fragile and diesel deliveries are risky, and that the team is still under 10 employees, according to an Oct profile. If the system can keep a remote base or island microgrid powered through the night, then scaling to larger civilian solar farms becomes a matter of replication rather than reinvention.
From remote islands to disaster zones
In my view, the most compelling part of the Aetherflux story is not the spectacle of lasers in the sky, but the mundane places where that power might quietly show up. The company’s angle is to harness the Sun’s energy and beam it to remote islands, areas struck by natural disasters, and other locations where traditional infrastructure is either too fragile or too expensive to build. That ambition is laid out clearly in a report on its planned 2026 test, which describes how Aetherflux wants to use orbital beams to keep critical services running when storms or earthquakes have knocked out conventional lines.
Those scenarios are not hypothetical edge cases. Island grids from Hawaii to the Caribbean still rely heavily on imported diesel, and disaster zones often depend on noisy, fuel-hungry generators that are hard to refuel when roads and ports are damaged. By sending power directly from orbit to compact receivers, a space-based system could, in theory, bypass broken transmission lines and fuel shortages entirely. That is why advocates of There SBSP projects in development argue that this technology is not just about adding more clean megawatts, but about hardening the most vulnerable parts of the energy system, a point echoed by Colby Carrier, who has been tracking how SBSP is edging closer to the launch pad.
Testing the concept in California and beyond
For all the grand talk of orbital constellations, the near-term test bed for this technology is decidedly terrestrial. The California-based startup is already experimenting with ground-to-ground power beaming, using lasers to send energy over shorter distances to prove out the safety systems, tracking accuracy, and conversion efficiency that will eventually be needed in orbit. A detailed profile notes that Meet the California firm Aet that is testing space-based solar farms designed to send power back to Earth, and that Aetherflux is not the only company exploring this path, with some rivals favoring microwaves instead of lasers.
Those early demonstrations are not just engineering milestones, they are political and regulatory ones. Proving that a high-power laser can be aimed, shuttered, and diffused safely if anything goes wrong is essential to winning over aviation authorities, local communities, and defense customers who will not tolerate uncontrolled beams in their airspace. At the same time, the company is preparing for orbital tests, with plans to deploy laser-powered satellites next as part of a broader push to beam solar power to Earth, a step that will move the concept from lab benches and desert ranges into the real environment it is meant to operate in.
A crowded race to beam power from orbit
Even as Aetherflux refines its own hardware, it is operating in a field that is suddenly crowded with competitors and alternative architectures. Some startups are betting on microwave beams instead of lasers, arguing that lower-frequency transmissions are less affected by clouds and can be spread over larger receiving areas, while others are focusing on smaller, niche payloads that can power individual facilities rather than entire regions. In that context, Aetherflux’s decision to concentrate energy into smaller spots on the ground and to lean on existing solar farms as receivers looks like a deliberate attempt to carve out a distinct lane within the broader SBSP ecosystem.
Industry trackers have highlighted that Aetherflux, founded by Robinhood co-founder Baiju Bhatt, is developing satellites with a 1-kilowatt capacity laser as part of its early systems, a detail that underscores how modest the first steps will be compared with the gigawatt-scale visions often associated with space power. That figure appears in a survey of four startups racing to make space-based power a reality, which notes that Aetherflux is one of several firms trying to move SBSP from concept studies into hardware. The race is not just about who can launch first, but who can find the right balance of power level, safety, and business model that will persuade utilities, militaries, and regulators to sign real contracts.
Money, risk and the path to a 2026 demo
For investors, the attraction of space-based solar power is that it promises both climate impact and infrastructure-style returns, but only if the technology can clear a daunting series of technical and regulatory hurdles. The California-based startup, launched by Baiju Bh, has already secured $50 m in backing, with that $50 million round framed as a bet that the company can move from concept to commercial pilot in just a few years. That funding, detailed in an analysis of how Aetherflux lands $50 million to deliver space-based solar power, is notable not only for its size but for the mix of climate-focused and tech-savvy backers it has attracted.
The company’s near-term goal is to translate that capital into a working demonstration that can silence skeptics who still see SBSP as a perpetual science project. Armed with a Series A round of $50 m, billionaire Baiju Bhatt is described by David Zarley as pushing toward a 2026 orbital test that would show lasers beaming real power from space to the surface, a milestone that could unlock larger follow-on rounds and, eventually, commercial contracts. In that account, David Zarley sketches a path in which the Series funding is not an endpoint but a starting gun for a sprint to orbit, with Baiju Bhatt trying to prove that his Wal Street fortune can buy not just rockets and satellites, but a new way of wiring the planet.
From sci-fi image to grid asset
What strikes me, looking across these reports, is how quickly the conversation around space-based solar power is shifting from speculative diagrams to concrete deployment questions. There are SBSP projects in the works that if less ambitious are closer to getting off the ground, and observers like Colby Carrier have pointed out that the field is now defined less by physics doubts than by questions of cost, regulation, and public acceptance. In that sense, Aetherflux’s focus on using lasers to top up existing solar farms at night is a pragmatic move, because it treats space power as an add-on to the grid rather than a wholesale replacement, a nuance captured in coverage of how SBSP advances toward the launch pad.
For now, the image of a U.S. firm aiming lasers at night to power solar farms from space still sounds like something out of a comic book. Yet the combination of a high-profile founder, a clearly articulated Aetherflux approach that leans on compact receivers, and a funding base willing to write $50 million checks suggests that this is no longer a purely speculative dream. If the planned 2026 demo succeeds, the glow on the horizon after sunset may not just be city lights, but the first hints of a grid that quietly draws part of its power from orbit.
