Tesla was spotted driving Cybertruck into the ocean in the Gulf of Mexico after Elon Musk claimed it would float.

Elon Musk has made claims before about how Tesla vehicles could float and briefly serve as a boat.

They have never been taken too seriously as Tesla’s warranty says something different about taking the vehicle into the water.

But the CEO doubled down on the claim with the Cybertruck – for which it makes more sense since it is supposed to be an off-road vehicle.

Last year, Musk claimed Tesla Cybertruck would be “waterproof enough” to serve as a boat and cross rivers:

Cybertruck will be waterproof enough to serve briefly as a boat, so it can cross rivers, lakes and even seas that aren’t too choppy.

The CEO added that the goal is for a Cybertruck to be able to cross the water between SpaceX’s Starbase and South Padre Island in Texas:

Needs be able to get from Starbase to South Padre Island, which requires crossing the channel.

At the shortest, the crossing is about 360 meters (1,100 feet).

Now, Tesla appears to be testing the Cybertruck’s waterproof capability in the wild.

Reddit user u/ilyasgnnndmr shared a video of Tesla driving a Cybertruck prototype into the waters of the Gulf of Mexico in Port Aransas, Texas:

You can see that the truck is not going too deep into the water, but it could be testing for an actual crossing as this location is not too far from South Padre Island.

We should learn more about the Cybertruck’s level of waterproofing at the delivery event on November 30th.

Day 1 of the Electrek Formula Sun Grand Prix 2025 [Gallery]

Day 1 of the Electrek Formula Sun Grand Prix 2025 [Gallery]

Today was the official start of racing at the Electrek Formula Sun Grand Prix 2025! There was a tremendous energy (and heat) on the ground at NCM Motorsports Park as nearly a dozen teams took to the track. Currently, as of writing, Stanford is ranked #1 in the SOV (Single-Occupant Vehicle) class with 68 registered laps. However, the fastest lap so far belongs to UC Berkeley, which clocked a 4:45 on the 3.15-mile track. That’s an average speed of just under 40 mph on nothing but solar energy. Not bad!

In the MOV (Multi-Occupant Vehicle) class, Polytechnique Montréal is narrowly ahead of Appalachian State by just 4 laps. At last year’s formula sun race, Polytechnique Montréal took first place overall in this class, and the team hopes to repeat that success. It’s still too early for prediction though, and anything can happen between now and the final day of racing on Saturday.

Congrats to the teams that made it on track today. We look forward to seeing even more out there tomorrow. In the meantime, here are some shots from today via the event’s wonderful photographer Cora Kennedy.

Stay tuned for more!

Tesla launches Oasis Supercharger with solar farm and off-grid batteries

Tesla launches Oasis Supercharger with solar farm and off-grid batteries

Tesla has launched its new Oasis Supercharger, the long-promised EV charging station of the future, with a solar farm and off-grid batteries.

Early in the deployment of the Supercharger network, Tesla promised to add solar arrays and batteries to the Supercharger stations, and CEO Elon Musk even said that most stations would be able to operate off-grid.

While Tesla did add solar and batteries to a few stations, the vast majority of them don’t have their own power system or have only minimal solar canopies.

Back in 2016, I asked Musk about this, and he said that it would now happen as Tesla had the “pieces now in place” with Supercharger V3, Powerpack V2, and SolarCity:

All of these pieces have been in place for years, and Tesla has now discontinued the Powerpack in favor of the Megapack. The Supercharger network is also transitioning to V4 stations.

Yet, solar and battery deployment haven’t accelerated much in the decade since Musk made that comment, but it is finally happening.

Last year, Tesla announced a new project called ‘Oasis’, which consists of a new model Supercharger station with a solar farm and battery storage enabling off-grid operations in Lost Hills, California.

Tesla has now unveiled the project and turned on most of the Supercharger stalls:

The project consists of 168 chargers, with half of them currently operational, making it one of the largest Supercharger stations in the world. However, that’s not even the most notable aspect of it.

The station is equipped with 11 MW of ground-mounted solar panels and canopies, spanning 30 acres of land, and 10 Tesla Megapacks with a total energy storage capacity of 39 MWh.

It can be operated off-grid, which is the case right now, according to Tesla.

With off-grid operations, Tesla was about to bring 84 stalls online just in time for the Fourth of July travel weekend. The rest of the stalls and a lounge are going to open later this year.

Electrek’s Take

This is awesome. A bit late, but awesome. This is what charging stations should be like: fully powered by renewable energy.

Unfortunately, it will be much harder to open those stations in the future due to legislation that Trump and the Republican Party have just passed, which removes incentives for solar and energy storage, adds taxes on them, and removes incentives to build batteries – all things that have helped Tesla considerably over the last few years.

The US is likely going to have a few tough years for EV adoption and renewable energy deployment.
