Tesla has highlighted its latest generation Powerwall in a recent advertisement, noting that it can continue to operate even when submerged underwater.
In a brief advertisement video shared on YouTube earlier this month, Tesla showed a demonstration of the recently released Powerwall 3 submerged in water and still powering appliances, noting that it can continue to operate in more than two feet of water.
The quick 30-second video shows the Powerwall 3 sitting in a fish tank full of water, while someone is still able to use a refrigerator, an electric stovetop, an espresso machine, and a television—despite the Tesla app showing that the area is undergoing an outage.
The video was also shared on other platforms than YouTube, including the Elon Musk-owned X, and it comes as part of larger advertising and educational efforts from Tesla in recent months.
You can watch the Tesla Powerwall 3 video below.
Advertising has become a hot topic amongst Tesla shareholders over the past few years, as many have called for the automaker and energy company to use ad platforms to raise awareness about its products amongst the public. CEO Elon Musk last year committed to start experimenting with small-scale ad campaigns, though Tesla ads have increasingly been spotted online and in real life in the early months of this year as the company has seemingly boosted its advertising efforts.
Tesla officially launched the Powerwall 3 in the U.S. in January, though specs for the new generation energy storage system were spotted on Tesla’s website last September. At the time, users still couldn’t purchase a Powerwall 3 through the company’s website, though installations of the upgraded hardware were quietly rolling out and were later highlighted by Musk.
The Powerwall 3 offers an energy capacity of 13.5 kWh and 11.5 kW of continuous backup power and on-grid power, as can be seen on Tesla’s website in the U.S. Crucially, it also includes an integrated solar inverter and system controller, unlike the last-generation Powerwall 2, and purchase comes with a 10-year warranty.
In multiple past outage and climate events, Powerwalls have helped homeowners and commercial spaces keep the lights on. Additionally, the systems have been used in recent years to pilot so-called “Virtual Power Plant” (VPP) programs, which pay a region’s network of Powerwall owners to essentially create a giant, distributed battery for the grid during periods of peak use.

Elon Musk reveals big plans for Tesla Optimus at the Supercharger Diner
Will Optimus deliver my Tesla Club on roller skates? I’m hopeful.

Elon Musk revealed on X on Wednesday that Tesla Optimus will soon be getting a job at the Supercharger Diner in Los Angeles, and its role will be right on par with what we believed the humanoid bot would be perfect for.
While Optimus was spotted serving popcorn at the Diner on Monday as it opened for the first time, that’s its only job, at least for now. Musk said Optimus will be getting a promotion in 2026, and it will be a food runner, bringing your order straight to your car, eliminating the need to go inside yourself.
It will complete what Tesla hopes is a full-fledged 50s diner experience, curated by the imagination of the future. In the 1950s, drive-in diners were a common hangout to grab a bite and watch a movie. Tesla opened its Supercharger Diner in Los Angeles earlier this week, but it has a futuristic twist to it.
You can order food directly from your car, sync your center touchscreen and speakers to the two massive projection screens that Tesla is playing movie scenes on at the Diner, and even go inside for a true break from your car.
Next year, Tesla will take it a step further, Musk confirmed:

The Diner features 80 Superchargers that can be used by both Tesla and non-Tesla EVs, provided that the manufacturer of the electric car has access to the company’s robust network. It is also available to non-EV owners, as they can park their cars and stop in for a quick bite to eat.
Tesla’s full menu at the Diner is available here, and its focus for the restaurant was to provide healthier options by sourcing most of its food from local, organic, and humane farms:
We put a lot of effort into using truly organic ingredients from farms that we have visited
— Elon Musk (@elonmusk) July 22, 2025
Optimus’s capabilities seem to be progressing to a point where Tesla feels confident that the humanoid robot can handle carrying food and delivering it to customers at their cars. Whether it will be put on roller skates is another question, but we’re hopeful Optimus can do it when it gets its promotion next year.
Investor's Corner
Tesla Q2 2025 earnings: What Wall Street expects
The company has faced mounting pressure this year, with TSLA stock down 19% year-to-date.

Tesla (NASDAQ:TSLA) is set to release its second-quarter 2025 financial results after markets close on Wednesday, July 23. The company has faced mounting pressure this year, with TSLA stock down about 19% year-to-date.
What Wall Street expects
As noted in a TipRanks report, Wall Street has remained cautious about the electric vehicle maker due to concerns about the EV segment in general, competition, reduced margins, federal EV regulations, and CEO Elon Musk’s political activities.
Overall, Wall Street expects Tesla to post earnings per share of $0.39, down 25% from a year ago. Tesla’s revenue is forecasted to fall 13% to $22.19 billion, and analysts also expect the electric vehicle maker to post lower margins this quarter.
Analyst expectations
Tesla delivered approximately 384,120 vehicles in Q2, a 13.5% drop year-over-year, as per Main Street Data. The company also produced over 410,000 vehicles and deployed 9.6 GWh of energy storage products during the quarter.
Ahead of the earnings call, Cantor Fitzgerald analyst Andres Sheppard reiterated a Buy rating and a $335 per share price target. He also adjusted his Q2 revenue forecast to $21 billion, down from his previous estimate of $24.1 billion. Despite short-term softness, Sheppard maintained his 2025 and 2026 projections, citing confidence in Tesla’s high-margin Robotaxi business model.
Barclays analyst Dan Levy kept a Hold rating with a $275 price target. He stated that the company faces “increasingly weaker fundamentals,” but he also suggested that Tesla’s Robotaxi story could drive optimism. Levy expects modest gross margin improvement quarter-over-quarter and flagged the full-year EPS estimate drop from $3.20 to $1.84. Delays in launching the affordable Tesla model remain a downside risk, Levy noted.

Tesla expands FSD Transfer offer to Europe and the Middle East
Tesla’s FSD transfer offer has long been used as a quarterly sales lever in North America.

Tesla has extended its Full Self-Driving (FSD) transfer promotion beyond North America, opening the door for owners in Europe and the Middle East to carry over their existing FSD systems to a new vehicle.
The move comes days after Elon Musk acknowledged a user’s request for FSD transfers in Europe on X, which the CEO called a “fair” ask. Tesla Europe later confirmed the offer via its official X account.
FSD transfers reaching new markets
FSD transfers have been used as a quarterly sales lever in North America, with its most recent availability in April 2025, as noted in a Not a Tesla App report. While this incentive had remained exclusive to the U.S. and Canada, Tesla’s latest announcement marks the first time the program has been rolled out internationally.
Interestingly enough, the offer hasn’t yet been extended to other FSD-enabled regions like China. This suggests that Tesla may be prioritizing markets where regulatory approval for FSD remains pending. European Tesla owners, after all, have been waiting literal years for FSD to be rolled out into their countries.
How the program works
The process for FSD transfers is straightforward. Existing Tesla owners with FSD must place a new vehicle order and complete delivery during the active promotion period. During checkout, customers are instructed not to add FSD to the new car. Instead, they must notify a Tesla advisor of their intent to transfer their existing vehicle’s FSD.
On delivery day, FSD will be deactivated on the old vehicle and activated on the new one. Customers are not required to trade in or sell their original Tesla that had FSD, though once the license is moved, the old vehicle reverts to just Basic Autopilot features.
