Diesel Just Hit a Record. Here's Why Your Groceries Care.

The EIA's weekly survey put US diesel at $5.967 a gallon for the week of September 7, above the June 2022 record of $5.810. Regular gasoline is $4.157 and nowhere near its own record. Diesel moves nearly everything you buy, so the gap between the two fuels is the number to watch.

Three iPhone screens from Apple showing the Photos app: a press-conference photo with a See Reference Image prompt, the signed reference image that still includes a second person at the edge of the frame, and the edited photo with that person retouched away

Your iPhone Can Now Prove a Photo Is Real. Here Is the Catch

The iPhone 18 Pro can sign every pixel its main camera captures and keep an unalterable reference copy beside the photo. It is a real advance in proving a photo was not edited, and it still proves less than the word "authenticity" suggests. It is opt-in, cannot be captured in the EU at launch, and sits outside the open standard Google, Samsung and Leica chose.

Power Station vs Generator: Real Cost per kWh and Runtime

A gasoline inverter generator delivers electricity at roughly 67 cents to just over a dollar per kilowatt-hour at September 2026 pump prices, from its own spec sheet. A battery power station delivers grid electricity at about 22 cents, plus a hardware cost that ranges from 20 cents to eight dollars per kilowatt-hour depending on how often you actually use it. Here is that math, a three-day outage runtime table, the noise and carbon monoxide numbers from the makers and the CPSC, what each one needs in maintenance, when the generator still wins, and how many miles either one can put into an EV.

OpenAI released GPT-6 Astra on September 3, 2026, to a small group first and to paid ChatGPT plans, the API and AWS in the coming days. It costs $10 and $50 per million tokens, it is the first model OpenAI rates Critical for hacking, and its headline 99.9% benchmark score falls to 62.7% on the benchmark's own standard setup.

Anthropic released Claude Fable 5.1 and Mythos 5.1 on September 1, 2026. The price stays at $10 and $50 per million tokens, cache reads drop 75%, and the model is now allowed to hunt software vulnerabilities, the same kind of task Anthropic says sat behind the jailbreak claim that got Fable 5 switched off in June.

Tesla Supercharger Cost: Per kWh, Per Fill, and vs Gas

There is no single Tesla Supercharger price. On September 8, 2026, seven Tesla site pages in Washington and Texas showed Tesla drivers paying anywhere from 17 to 50 cents per kilowatt-hour depending on the site and the hour, with other EVs paying 39 to 52 percent more at the three sites open to them. A Model 3 adding 100 miles pays about 5 to 12 dollars at those rates, against about 4.50 at home and 15 on gas. Here is why every site is priced differently, what a full charge costs by model, how the congestion fee works, and how to read your own rate before you plug in.

Why Your Tesla Is Charging Slowly (and When It's Normal)

A Tesla charging slowly is usually doing what its charger allows. A standard 120-volt outlet adds 2 to 3 miles of range an hour, a 240-volt outlet up to 30, and a Wall Connector up to 44, per Tesla's own home-charging page. At a Supercharger the rate falls as the battery fills, drops in the cold, and can drop again on sites where two stalls share one power cabinet. Here is every documented cause, the number that counts as normal for each, and the one setting that quietly caps your car.

Tesla Maintenance Cost Per Year: Every Required Item, Priced

Tesla's owner's manual lists four scheduled maintenance items for a Model 3 (five on a Model Y, which adds its HEPA filters): a brake-fluid health check every 4 years, a cabin air filter every 2 years, a tire rotation every 6,250 miles, and caliper cleaning every year only where roads are salted. Priced from Tesla's own shop and dated tire quotes, five years and 75,000 miles of that schedule plus the tires and wipers it leaves out comes to roughly 280 to 460 dollars a year depending on who rotates the tires, with one set of tires making up most of the bill. Here is the schedule for every model, each item priced, and how the number compares to RepairPal, CarEdge and AAA.

Big Tech's $176B Profit That Isn't Really There

Alphabet's revenue rose 24 percent last quarter while its depreciation bill jumped 42 percent and its free cash flow went negative. The gap between reported profit and real cash comes down to one accounting choice: how long a company pretends its AI chips will last. Michael Burry estimates that choice hides roughly 176 billion dollars of overstated profit across Big Tech.
