Tesla Cybertruck’s potential amphibious capabilities are starting to become realistic

In a recent lighthearted post, Tesla CEO Elon Musk referenced the Cybertruck’s potential amphibious capabilities once more. Musk’s tweet was a response to a rather humorous concept video featuring the all-electric pickup being used as a boat. And while such a concept may be farfetched for the skeptics, the idea of an amphibious vehicle may actually be pretty feasible. 

The amusing render was created by Slav Popovski, the same 3D artist that came up with a realistic concept video of the next-gen Tesla Roadster SpaceX Package’s 0-60 mph launch. Musk, for his part, stated that Tesla could probably give the all-electric pickup a similar function. “I think we could make it work,” the CEO noted. This echoed a previous tweet that Musk posted in April, when he noted that the Cybertruck would “float for a while” when traversing deep waters.

Recent images of the Tesla Cybertruck at the Petersen Automotive Museum have revealed that the vehicle may actually be designed to resist being breached with water. As indicated by pictures from the Tesla community, several sections of the Cybertruck’s underbody seem to be watertight, and the vehicle’s suspension area seemed to be sealed as well. This suggests that Elon Musk’s statements about the Cybertruck’s amphibious capabilities may be less outlandish than expected.

Musk has been pretty open about his love for vehicles that can travel on both land and water. In 2013, Musk purchased the actual Lotus Esprit S1 movie prop from the 1977 James Bond film The Spy Who Loved Me, which became iconic due to its capability to transform from a sports car into a submarine. Musk would later joke that he was disappointed to find out that the Lotus did not really transform into a submarine, and that he would probably attempt an amphibious vehicle using Tesla tech. 

The CEO revisited this idea in the 2019 Annual Shareholder Meeting, when he stated that a submarine car is “technically possible.” Musk did admit that the market for such vehicles would be small, but he suggested that there will probably be a lot of enthusiasm around the project. 

A novel amphibious car has actually been attempted over ten years ago by Swiss niche automaker Rinspeed. During the Geneva Motor Show in 2008, the company took the wraps off its all-electric sQuba amphibious sports car. The vehicle ran on lithium ion batteries and was built on top of a Lotus Elise, which actually makes it pretty similar to the original Tesla Roadster, at least to some degree.

Granted, the sQuba was slower than Tesla’s sports car with its top speed of 75 mph, but it does have the capability to travel over water, and up to 33 ft underwater. The vehicle even came equipped with scuba tanks for its two passengers, which are incredibly useful when the vehicle is in its submarine configuration. Unfortunately, the sQuba has so far not made it to production, with Rinspeed founder and CEO Frank M. Rinderknecht stating that the appeal of such a vehicle is very limited due to the fact that it was mostly a toy for the wealthy. 

But the Cybertruck is no niche vehicle, nor is it a novel toy for the rich. Starting at less than $40,000 for its RWD variant, the Cybertruck is made for utility and actual, tough work. This means that if the Cybertruck were to have actual amphibious abilities, it could have practical, real-world uses. The vehicle could be used as a rescue pickup for the Coast Guard, for example, since it could function as a boat to some degree.

Of course, these are all speculations for now. That being said, Elon Musk does have a reputation for bringing to market products and features that were initially thought of as a joke. The Boring Company’s Not-a-Flamethrower is one of these, and Tesla’s amusing Emissions Testing Mode (aka Fart Mode) is another. With these in mind, and with the Cybertruck seemingly being designed to withstand water, perhaps the idea of an amphibious all-electric pickup is not too farfetched after all.

Why Tesla Roadster unveiling delay might have nothing to do with it flying

Published

on

Tesla announced on Monday that the Roadster event scheduled for today would be postponed due to the need for it to be held outside.

Less than 24 hours later, CEO Elon Musk broadened that by stating it was due to high winds, immediately sending everyone into a frenzy over the Roadster’s potential ability to fly.

And realistically, it could definitely have to do with it flying, hovering, or hopping; whatever Tesla has in mind for this demonstration could not be impacted by wind. However, it might have nothing to do with the vehicle flying whatsoever, and instead could be a simple precaution, as the Roadster is a very unique vehicle with some already official specs that are just mind-blowing.

Tesla will very, very likely be showcasing both the acceleration rate and potentially even a top speed demo at the event in Waco. Both of these demonstrations, performed with a vehicle that has such incredibly fast metrics, could easily be impacted by wind as well.

Tesla Roadster event requires restricted airspace, and the FAA obliges

Top Speed Demo

At high speeds, aerodynamic forces are already overwhelmingly present. A crosswind or sudden gust adds a layer of sideways force that the tires must counter with slip angle. On a short demo course, that force can shove the car off the intended line, especially in a light car with a low frontal area and little mass to resist the push.

Electric cars, due to their battery packs, have an advantage of an extremely low center of gravity, giving them extra stability. However, the speeds at which the Roadster could travel at the demo could spell some issues if crosswinds are present.

Gusts are worse than a steady wind because the load changes faster than a driver can smoothly correct. That shows up as weaving or a late correction. Headwinds and tailwinds can also spell disaster. Headwinds cut a measured top speed but raise the power needed to get there or maintain it. Meanwhile, a tailwind can inflate the top speed, and downforce issues could become more noticeable.

Wind also loads the body unevenly. A low car can feel light on the upwind side or see a sudden change in downforce if the gust hits a wing or diffuser at an angle. Tire temperature and pressure might stay near a normal level, but lateral grip can be lost as the vehicle is spent fighting the wind.

Acceleration Demo

Launch and 0-60 MPH runs are shorter, so the car spends less time exposed to forces that could cause things to go awry. However, the first second is very sensitive, as a crosswind at launch could yaw the car before speed builds and prior to aerodynamic impact being too great. The driver will be required to correct traction control or manage how much the wheels are spinning, which will likely be corrected automatically by some sort of traction control system within the Roadster (we are fairly certain Tesla will implement something brilliant with it).

These things could cause an unstable run.

A headwind would increase drag as speed rises, while a tailwind would do the opposite. Meanwhile, surface effects, like wind-driven dust, light debris, or even rain, could reduce grip at the exact moment the tires are asked for peak longitudinal force. Standing water plus a crosswind is a common reason an acceleration attempt might be scrapped.

Flying or Not

No matter what Tesla has in store for the Roadster, waiting for ideal conditions is a great idea. People who follow and support the company, along with the engineers involved in the Roadster program, have been waiting nine years since the last unveiling for this moment. Everything should be ideal.

Some speculate that it’s just not ready, and that’s ridiculous. Why would Tesla even schedule the event — albeit prematurely — after nine years if it was not ready? Why would they jump the gun now?

We were all excited for today, but it truly is the most ideal thing in the world to wait two more weeks so everything, including the weather, can be perfect. The delay is simply worth it. But Tesla, seriously, make this the last one.

SpaceX nails “Lucky 13” astronaut launch, leaning into Tesla tradition and superstition

SpaceX launched Crew-13 astronauts to the ISS Thursday, setting up a record fast Dragon docking.

SpaceX launched NASA’s Crew-13 mission to the International Space Station on Thursday morning, getting four astronauts to orbit despite a forecast of thunderstorms and gusty winds that had threatened to push the flight to Friday.

Falcon 9 lifted off from Space Launch Complex 40 at Cape Canaveral Space Force Station at 11:10 a.m. ET carrying Dragon Grace, NASA confirmed. On board are NASA commander Jessica Watkins, NASA pilot Luke Delaney, Canadian Space Agency astronaut Joshua Kutryk and Roscosmos cosmonaut Sergey Teteryatnikov. The first stage booster, B1101, landed at Landing Zone 40 beside the pad on its third flight after previously supporting Crew-12 and a Starlink mission.

It was the first spaceflight for Delaney, Kutryk and Teteryatnikov. Watkins, who flew on Crew-4 in 2022, became the first NASA astronaut to launch aboard a Crew Dragon twice.

Before launch, the crew rode to the pad in Teslas, a tradition on NASA’s SpaceX crew flights since 2020. This time the cars carried specialty plates reading “Lucky 13.” Watkins said the mission patch leans into the number on purpose, as a nod to Apollo 13 and the resilience of that crew.

Grace is now on a short trip to the station. Docking at the forward port of the Harmony module is scheduled for about 7 p.m. ET, roughly 7 hours and 50 minutes after liftoff, which Space.com notes would be the fastest Crew Dragon transit to the ISS yet. Most Dragon flights take around 15 to 24 hours to catch the station. Hatch opening is planned for 8:25 p.m. ET.

The launch came more than two weeks later than originally planned. An oxidizer leak was found in Grace’s propulsion system in August, and NASA and SpaceX added time for tests. That pushed back the return of Crew-12, which has been aboard the station since February and is now set to splash down off Southern California next week. Crew-13 is expected to stay about six months.

SpaceX rescue mission for stranded ISS astronauts nears end — Here’s when they’ll return home

SpaceX already holds NASA orders for crew rotations through Crew-17, while Boeing is preparing an uncrewed Starliner flight to the station as early as December.

Crew-13 was only the first of three SpaceX launches planned for Thursday, as Teslarati previewed on Wednesday. A Falcon 9 launched its Transporter-18 mission from California today, where Google will be launching its first orbital artificial intelligence (AI) test satellite. Meanwhile, Falcon Heavy is set to launch the classified NROL-97 mission for the National Reconnaissance Office from Launch Complex 39A at 11:53 p.m. ET. Its two side boosters will return to Landing Zones 1 and 2, which means Central Florida could hear up to three sonic booms in a single day. The busy stretch follows Starship’s Flight 14 on Monday, which reached orbit for the first time.

Tesla moves forward on Wireless Charging for vehicles

Tesla has moved its Wireless Charging efforts for its electric vehicles forward, as it had a new patent published today, one that it submitted back in March.

The patent describes a system for detecting foreign objects on the wireless charging pad under varying temperatures, aiming to mitigate any undesired results that could come from something being on top of the charging pad.

The abstract of the patent states:

“The present disclosure relates to methods and systems that can reliably detect foreign objects on a wireless charging pad under varying temperatures. In some examples, an object detector can utilize a set of inductive coils included in resonant tanks, and excite the resonant tanks using signals in a range of frequencies including or near a nominal resonant frequency of the resonant tanks. The object detector can detect a metal object based on resistance of a coil increasing and inductance of the coil decreasing. By analyzing the shifts and/or distributions in resonant frequencies and output magnitudes (e.g., output voltage peaks), the object detector can distinguish between changes of frequencies and magnitudes caused by temperature and those caused by foreign objects to accurately detect the foreign objects.”

The object detection system will utilize a set of inductive coils included in resonant tanks, and “excite the resonant tank using signals in a range of frequencies including or near a nominal resonant frequency of the tanks.” Metal can be detected by an increase in the coil’s resistance and a decrease in the coil’s inductance.

By analyzing shifts or disruptions in resonant frequencies and output magnitudes, the system can detect foreign objects. These types of safeguards need to be implemented through the normal operation of the charging pads.

Tesla says its Cybercab wireless charging efficiency is ‘well above 90%’

Tesla plans to utilize wireless charging with Cybercab and Robotaxi-enabled units to help streamline the fully autonomous experience from A to Z. The last thing the company wants to do is have any sort of small obstruction preventing the rider from experiencing Robotaxi as intended.
