Tesla Hacker reveals impressive ‘off-grid’ home powered by Model S batteries

Published

on

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.

Elon Musk’s answer to Christopher Nolan’s Odyssey got way more specific

Published

on

By

Elon Musk escalated his monthslong feud with Christopher Nolan’s The Odyssey this week, pledging that his own AI video tool will produce a competing version before the year is out. Responding to a fan-made, AI-generated clip of the ancient epic, Musk wrote on X, “Before this year ends, Grok Imagine will make a full-length movie of The Odyssey that is historically accurate and true to the art of Homer.”

In June, Musk quoted an xAI-shared trailer built entirely with Grok Imagine Video 1.5, a two-minute-plus reimagining of The Odyssey styled after a 1970s classical Hollywood epic, and predicted “full movies by the end of the year,” as Teslarati reported at the time. That trailer, built from 36 consistent shots by a single creator, was Musk’s proof of concept. This week’s pledge turns that prediction into a specific commitment, tied directly to Homer’s text rather than a generic demo.


When a fan separately proposed that Musk fund a live-action alternative, to “give Mel Gibson $100 million to film an Odyssey adaptation with painstakingly historically accurate ships, armour, weapons, and casting, with all dialogue taken straight from the original poem and delivered in Homeric Greek,” Musk replied with two words: “I’m down.”

The Grok Imagine pledge lands as the tool’s underlying infrastructure has changed hands. Grok is no longer a standalone product, it folded into SpaceXAI after SpaceX’s acquisition of xAI closed in February, meaning the compute behind any Odyssey production traces back to the same Colossus supercomputers now bundled into SpaceX’s pitch to investors. Musk has separately said SpaceX’s own engineering data is being fed into the next major Grok training run, a two trillion parameter model he’s called the “2T run.”

Whether Grok Imagine can sustain a feature length narrative, rather than a series of impressive individual shots, remains the open question.

Tesla Mobile App gets a new feature that wrap fans are going to love

Tesla’s Summer Update removes the USB drive step from customizing your car’s digital wrap design.

Published

Tesla’s latest 2026 Summer Update quietly closes out one of the more tedious steps in personalizing a Tesla’s digital appearance. Uploading a custom wrap design used to require a USB drive. Now it doesn’t.

The feature is listed in Tesla’s release notes as “Send Custom Wraps from Mobile App.” The company described it plainly: “Skip the USB drive and upload a custom wrap of your car from the mobile app. Instructions for creating a custom wrap here: github.com/teslamotors/custom-wraps.”

The digital wrap tool has been around since Tesla’s 2024 Holiday Update, when it launched for Cybertruck owners first, as Teslarati reported at the time. Getting a design onto the car meant formatting a USB drive, creating a folder named exactly “Wraps,” dropping in PNG files sized between 512×512 and 1024×1024 pixels and under 1 MB each, then plugging the drive in and applying the wrap through Toybox. Tesla expanded the tool to other models and renamed it from “Colorizer” to “Paint Shop” with the 2025 Holiday Update, while also adding license plate and window tint customization alongside the wraps.

The latest Summer Update removes the USB step from that process. Owners will be able to pull a design from wherever they saved it, whether that’s a download from social media or something built from Tesla’s own GitHub templates, and push it to the car directly through the app.

It’s a small fix relative to the rest of this latest release, which also included expanded Grok voice commands, automatic navigation that learns regular routes, and self-driving stats inside the mobile app, all detailed in our rundown of the full Summer Update. The USB requirement was one of the more common complaints about Paint Shop since it launched. Tesla did not say when the wrap upload change would reach individual vehicles, only that the broader update is rolling out now in waves.

Tesla Diner is throwing a birthday party with a Franz-signed special treat

Tesla Diner turns one on July 21 with Optimus, roller skates, and a Franz-signed hat.

Tesla is throwing its Hollywood Diner a first birthday party on July 21 and the celebration comes with a guest list of unique items, including a limited run of Tesla Diner birthday hats personally signed by Tesla Chief Designer Franz von Holzhausen for the first 50 customers who place an in-car order at midnight.

One year after lines wrapped around the block on Santa Monica Boulevard for a diner that most of the restaurant industry did not take seriously, Tesla is making the case that the concept was worth the years it took to build. The concept had been in Musk’s head since at least 2018, when he floated the idea of “an old school drive-in, roller skates and rock restaurant” on X, describing it years later as “‘Grease’ meets ‘The Jetsons’ with Supercharging.”

Tesla Optimus Gen 3 is coming to the Tesla Diner with new ambitions

 

What made the diner genuinely different from any restaurant that came before it was not the menu or the nostalgia. It was the ordering model. Tesla owners could place food orders directly from their vehicle’s touchscreen before arriving, a small feature that hints at something much larger on the horizon. As the Cybercab and unsupervised FSD expand across major cities, the diner model becomes a template for an entirely new kind of commerce. A robotaxi pulling in to charge does not need a human to walk up to a counter. The vehicle places the order, the food is ready on arrival, and the passenger never interrupts the experience of being driven somewhere else. It is the first glimpse of what drive-through commerce looks like when the car is doing the driving.

As Teslarati has reported, Musk signaled immediately after opening that the Hollywood location was only the beginning, posting that Tesla would expand the concept to major cities worldwide and along Supercharger corridors on long-distance routes if the first location proved successful. One year in, the birthday celebration on July 21 makes a strong case that it has. Tesla announced a full day of events including a Cybercab on display, a birthday menu, Optimus in attendance, face painting, a photo booth, roller skating servers, a light show, a Skypad DJ, and complimentary collectibles.

If Musk’s ambition holds, the Hollywood diner is year one of something much bigger. The birthday party is the proof of concept. The robotaxi fleet is the business model waiting behind it.
