Tesla Hacker reveals impressive ‘off-grid’ home powered by Model S batteries
Jason Hughes, white hat hacker who’s perhaps best known as the man who leaked Tesla’s plans for a P100D a half year ahead of the company’s actual announcement, has revealed photos of his impressive Tesla battery powered compound in North Carolina. The 4,500 square-foot home utilizes 102 commercial-grade solar panels to capture energy from the sun which then gets stored into a home battery storage unit composed of battery modules ripped from two Tesla Model S 85 kWh packs.
The 44.4 kW home solar system produces enough energy to not only power the entire home and all of its electrical appliances, but also provides enough energy to charge a pair of his and hers Model S each day. The end result is an elaborate home-engineered system that took roughly a year to design and build, and has allowed Hughes and his family to remain 99% ‘off-grid’ for the past year. A measly $200 was paid to the utility company for the entire year, most of which, according to Hughes, was a base connection fee to keep the meters operational.
The battery banks used for storing solar energy are derived from battery packs found from a salvaged Model S. Hughes dismantled the packs to create a stacked array of battery modules. A total of 36 modules are used in the home set up which equates to 2.25x Model S 85 kWh battery packs. Here’s a video of Hughes performing a teardown of one of the Model S battery packs.

Hughes tells us that inquiries on cost are probably the number one question he gets asked. A large portion of the overall expenditure went to the $40k cost in Tesla batteries. He admits that the project likely doesn’t make sense from a financial perspective given that his utility rate is only billed at a flat $.11/kWh, but it’s important to understand that the value of his project goes beyond what a cost benefit analysis may yield.
Beyond being able to show that living solely off of sustainable energy is possible, the main inspiration behind his yearlong project was his father who taught him at a young age of 9 how to build a small off-grid solar system that produced enough energy to power his bedroom light, a small TV and a PC. That became the catalyst to what would become a lifelong dream to design an off-grid system capable of powering an entire house, along with electric vehicles.

The FCC just said ‘No’ to SpaceX for now
SpaceX is fighting the FCC for spectrum that could put satellites inside every smartphone.
SpaceX was dealt a new setback on April 23, 2006 by the Federal Communications Commission (FCC) after the U.S. government agency dismissed the company’s petition to access a Mobile Satellite Service spectrum that would allow direct-to-device (D2D) capabilities.
The FCC regulates communications by radio, television, wire, and cable, which also includes regulating D2D technology that lets your existing smartphone connect directly to a satellite orbiting Earth, the same way it would connect to a cell tower.
Elon Musk’s SpaceX has been building toward this through its Starlink Mobile service, formerly called Direct-to-Cell, in partnership with T-Mobile. The service officially launched on July 23, 2025, starting with messaging and expanding to broadband data in October of that year.
T-Mobile Starlink Pricing Announced – Early Adopters Get Exclusive Discount
It’s worth noting that SpaceX is not alone in this race. AT&T and Verizon have their own satellite texting deals with AST SpaceMobile, while Verizon separately offers free satellite texting through Skylo on newer phones.
The regulatory foundation for all of this dates to March 14, 2024, when the FCC adopted the world’s first framework for what it called Supplemental Coverage from Space, allowing satellite operators to lease spectrum from terrestrial carriers and fill gaps in their coverage. On November 26, 2024, the FCC granted SpaceX the first-ever authorization under that framework, approving its partnership with T-Mobile to provide service in specific frequency bands. SpaceX then went further, completing a roughly $17 billion acquisition of wireless spectrum from EchoStar, which gave it the ability to negotiate with global carriers more independently.
Starlink’s EchoStar spectrum deal could bring 5G coverage anywhere
This recent ruling by the FCC blocked SpaceX from going further, protecting incumbent spectrum holders like Globalstar and Iridium. But the market momentum is already in motion. As Teslarati reported, SpaceX is targeting peak speeds of 150 Mbps per user for its next generation Direct-to-Cell service, compared to roughly 4 Mbps today, which would bring satellite connectivity close to standard carrier performance.
With a reported IPO targeting a $1.75 trillion valuation on the horizon, each spectrum fight, carrier deal, and regulatory win or loss now carries weight beyond just connectivity. SpaceX is quietly becoming the infrastructure layer underneath the phones of millions of people, and the FCC’s next move will help determine how much further that reach extends.

Elon Musk talks Tesla Roadster’s future
Elon Musk confirmed the Roadster as Tesla’s last manually driven car, with a debut coming soon.
During Tesla’s Q1 2026 earnings call on April 22, Elon Musk made a brief but notable comment about the long-awaited next generation Roadster while describing Tesla’s future vehicle lineup. “Long term, the only manually driven car will be the new Tesla Roadster,” he said. “Speaking of which, we may be able to debut that in a month or so. It requires a lot of testing and validation before we can actually have a demo and not have something go wrong with the demo.”
That single statement is the entire Roadster update from yesterday’s call, and while it represents another timeline shift, it comes as no surprise with Tesla heads-down-at-work on the mass rollout of its Robotaxi service across US cities, and the industrial scale production of the humanoid Optimus.
The fact that Musk specifically framed the Roadster as the last manually driven Tesla is significant on its own. As the rest of the lineup moves toward full autonomy, the Roadster becomes something rare in the Tesla-sphere by keeping the driver in control. Driving enthusiasts who buy a $200,000 supercar are not doing so to be passengers. They want the physical connection to the road, the feel of acceleration under their own input, and the experience of controlling something with that level of performance. FSD, however capable it becomes, removes that entirely. The Roadster signals that Tesla understands this distinction and is building a car specifically for the people who consider driving itself the point.
Tesla isn’t joking about building Optimus at an industrial scale: Here we go
The specs for the Roadster Musk has teased over the years are genuinely unlike anything in production. The base model targets 0 to 60 mph in 1.9 seconds, a top speed above 250 mph, and up to 620 miles of range from a 200 kWh battery. The optional SpaceX package takes it further, rumored to add roughly ten cold gas thrusters operating at 10,000 psi, borrowed directly from Falcon 9 rocket technology. With thrusters, Musk has claimed 0 to 60 mph in as little as 1.1 seconds. In a 2021 Joe Rogan interview he went further, stating “I want it to hover. We got to figure out how to make it hover without killing people.” Tesla filed a patent for ground effect technology in August 2025, suggesting the hover concept has not been abandoned. The starting price remains $200,000, with the Founders Series requiring a $250,000 full deposit. Some reservation holders placed those deposits in 2017 and are approaching a full decade of waiting.
With production now targeted for 2027 or 2028 at the earliest, the Roadster remains Tesla’s most audacious promise and its longest-running delay. But if what Musk is testing lives up to even half of what he has described, the demo alone should be worth waiting for.

Tesla isn’t joking about building Optimus at an industrial scale: Here we go
Tesla’s Optimus factory in Texas targets 10 million robots yearly, with 5.2 million square feet under construction.
Tesla’s Q1 2026 Update Letter, released today, confirms that first generation Optimus production lines are now well underway at its Fremont, California factory, with a pilot line targeting one million robots per year to start. Of bigger note is a shared aerial image of a large piece of land adjacent to Gigafactory Texas, that Tesla has prominently labeled “Optimus factory site preparation.”
Permit documents show Tesla is seeking to add over 5.2 million square feet of new building space to the Giga Texas North Campus by the end of 2026, at an estimated construction investment of $5 billion to $10 billion. The longer term production target for that facility is 10 million Optimus units per year. Giga Texas already sits on 2,500 acres with over 10 million square feet of existing factory floor, and the North Campus expansion is being built to support multiple projects, including the dedicated Optimus factory, the Terafab chip fabrication facility (a joint Tesla/SpaceX/xAI venture), a Cybercab test track, road infrastructure, and supporting facilities.
Texas makes strategic sense beyond the existing infrastructure. The state’s tax structure, lower labor costs relative to California, and the proximity to Tesla’s AI training cluster Cortex 1 and 2, both located at Giga Texas and now totaling over 230,000 H100 equivalent GPUs, means the Optimus software stack and the factory producing the hardware will share the same campus. Tesla’s Q1 report also confirmed completion of the AI5 chip tape out in April, the inference processor designed specifically to power Optimus units in the field.
As Teslarati reported, the Texas facility is intended to house Optimus V4 production at full scale. Musk told the World Economic Forum in January that Tesla plans to sell Optimus to the public by end of 2027 at a price between $20,000 and $30,000, stating, “I think everyone on earth is going to have one and want one.” He has previously pegged long term demand for general purpose humanoid robots at over 20 billion units globally, citing both consumer and industrial use cases.
