Tesla Cybertruck is perfect for Elon Musk’s dream HVAC system
Tesla CEO Elon Musk teased the idea of integrating its upcoming Cybertruck with a quiet and efficient HVAC system that’s also capable of distilling water. And while water distillation from a utility vehicle may seem overkill, it makes perfect sense to include such a feature in the futuristic stainless steel behemoth.
The idea became apparent during a conversation with Joe Rogan nearly two years ago, but the idea has since gained more traction. In a tweet that reiterated his desire for a “super-efficient, quiet home HVAC with HEPA & water distillation,” one of the CEO’s Twitter followers asked if he was more interested in developing the system than working on the Cybertruck. However, Musk answered by saying, “Maybe Cybertruck will have it…”
When Musk appeared on the Joe Rogan Experience Podcast in September 2018, he spoke of an intelligent home HVAC system that would only cool rooms that have people in them. This idea would increase efficiency and eliminate wasted energy throughout a home. However, it would seem that the Cybertruck may receive something along the same lines.
I’m dying to do super efficient, quiet home HVAC with HEPA & water distillation. It’s weird, but I really want to do it.

Maybe Cybertruck will have it …

Having an energy-efficient HVAC system bodes well for the Tesla Cybertruck, which aims to have long-range capabilities at an affordable price point. Also, considering the vehicle’s spacious interior cabin, having an efficient heating and cooling system would reduce range-robbing energy on something as large as the Cybertruck.
The Cybertruck will likely be Tesla’s most significant vehicle to date, leaving no doubt that the powerhouse truck can accommodate a HEPA filter. The installation of this filter keeps air quality within the cabin of the vehicle extremely high. Tesla’s “Bioweapon Defense Mode,” which the company developed to protect passengers from the dangers of environmental pollution, would also be a perfect fit for the upcoming vehicle.
But Musk’s vision for the Cybertruck goes far beyond the third rock from the sun. Perhaps its purpose is geared towards life on Mars, just as much as it is for Earth.
Musk’s narratives in the past have playfully hinted at survival during cataclysmic events, with the CEO emphasizing that Teslas run off of sunlight, which will be available for far longer than fossil fuels. But Elon’s playful jokes could be a hint at something more serious, like the inevitable destruction of Earth if pollution-producing forms of energy continue to be used as fuel.
The Cybertruck’s exoskeleton and robust stainless steel body actually make it ideal for a dangerous future. The pickup’s already durable build combined with range, speed, and sustainability could be a difference-maker for passengers even in otherwise risky events. An intelligent HVAC unit, an air filtration system, and a water distillation feature just makes the all-electric pickup an even better survival tool.
Tesla Cybertruck (pressurized edition) will be official truck of Mars

But Musk seems to believe each of these items could be added onto the Cybertruck, allowing it to operate anywhere, even if the location isn’t on Earth. After all, he did say the Cybertruck’s “pressurized edition” would be the official truck of Mars.
Perhaps the Cybertruck, when paired with Bioweapon Defense Mode, an HVAC unit, and a water distillation feature, could be one of the vehicles of choice for people when things on Earth start going south due to the climate crisis.
Protecting the passengers in the car has always been a goal of Tesla, but the purpose goes much further than accident and collision safety. Musk has made several attempts to improve the air purification systems within the cars, for example, an aspect of safety that is rarely explored by traditional automakers. “Air quality has a much bigger effect on health than people realize,” he said.
The Cybertruck’s mission is likely to protect people from accidents and dirty air. The vehicle’s future could be a large part of Musk’s “Master Plan,” which entails a push towards sustainability. But beyond Earth, the priorities of Tesla will still apply. On Mars, people will surely need clean air, protection from harmful rays, and a water source. The Cybertruck just happens to be a great vehicle to provide all that, and more.

How to use Grok Bot to block spam calls and texts
Musk told users to ask Grok Bot to scrub their phone numbers from spam lists.
Elon Musk has a new use case for Grok Bot, and it is the spam call. On Thursday he replied to an X user named Arash with a short instruction: “Ask your @Grok @Bot to remove your phone number from spam call & text lists!” Arash had said he got tired of the calls, had an AI bot find his number on listing sites and file removal requests, and packaged the process as a free skill for others.
The skill is called Spam-Call Scrubber, which is described to find a phone number on people search sites and data brokers, submits the opt outs, completes the confirmation emails those sites send back, and rechecks on a schedule the user picks. Using it requires the Grok Bot app. The pitch is time saved, since most broker opt outs sit behind separate forms on separate sites.
Ask your @Grok @Bot to remove your phone number from spam call & text lists!

Musk said Grok Bot now gives each bot its own email address, and that it can detect scam emails. On Thursday he also said SpaceX would make users whole if the bot botches a purchase or leaks a card, then told users to shop away from Amazon after the retailer blocked the agent, as Teslarati reported. The terms of service we reviewed at the time put responsibility for what an agent does on the user.
For Tesla owners, Grok Bot is not just a phone app. Tesla brought Grok Bot into its vehicles on September 22, and we argued earlier this week that the Cybercab’s real advantage may be the errands it runs during a ride. Every Cybercab and the rest of the Model Y Robotaxi fleet has it enabled. The more routine tasks like this one become, the more a rider has reason to hand over something personal in the back seat.
The new Spam-Call Scrubber skill can be downloaded for free and works on sites that honor removal requests, while noting that listings can reappear, and illegal robocallers do not check any registry. Whether Spam-Call Scrubber cuts anyone’s call volume is something the first wave of users will find out, and Musk’s endorsement guarantees that wave is coming.
Investor's Corner
Tesla’s flying Roadster just revealed something bigger than the car
Analysts say the Roadster demo puts a Tesla and SpaceX merger back on the table.
The Roadster unveiling near Waco ended Thursday night, and by Friday morning much of the investor reaction had less to do with the car than with who owns the rocket technology inside it.
Wedbush analyst Dan Ives said the event “puts the Tesla/SpaceX relationship on the table in a tangible way,” pointing to the propulsion, pressure vessel and control hardware sitting on a Tesla product. Gene Munster of Deepwater Asset Management called the demo “a ridiculous display of engineering” with “no commercial value” beyond embarrassing traditional automakers, though he said it showed Musk wants the two companies together.
The more specific forecast came a day earlier from Barclays. Analyst Dan Levy told clients a deal could be announced before Tesla’s annual meeting, which must happen by December 6, and that an announcement in late October or early November could make shareholder approval harder. Barclays expects SpaceX to be the buyer in an all stock deal, with Tesla holders receiving SpaceX shares at a premium, based on market values of roughly $2.1 trillion for SpaceX and $1.5 trillion for Tesla. If nothing lands around the meeting, the bank still sees an announcement within 6 to 12 months.
The Roadster demo just added more weight to merger speculations. Tesla’s demo used cold gas thrusters and pressure tanks of the kind SpaceX uses on Falcon 9, and Musk described the car as a collaboration between Tesla and SpaceX engineers, as we mentioned in our breakdown of the three Roadster configurations.
Musk has not publicly addressed a deal since the event, as far as we have seen. His most direct answer remains the one he gave at the All In Summit, when he said that with so much collaboration, “who can imagine what action one might take” without ruling anything out. Ives has held to a 2027 timeline since his March note, and Musk pushed back on the China piece of the speculation when ARK floated a year end announcement in August.
The next test is Tesla’s third quarter earnings call on October 21. However, we recall in July that Musk told analysts, “we can’t talk about combining companies and that kind of thing on an earnings call,” so a clear answer wouldn’t be expected.

How Tesla’s Roadster fan system and thrusters are built to dominate the corners
Tesla’s Roadster uses fans, active wings and cold gas thrusters to create grip at any speed.
Tesla’s new Roadster is best known for flipping through the air in Texas, but the technology that matters most for a race track is the stuff that keeps it on the ground. Tesla’s Roadster page describes a multi-mode fan and ground sealing system that acts as a downforce generator, pulling air out from beneath the car. Tesla says it provides enough suction to hold the vehicle upside down, even when stationary.
That is the key difference from the wings and diffusers on a normal supercar. Conventional aero only makes downforce when the car is moving, and it grows with speed, so a car has the least grip in the slow corners and under hard braking. A fan system makes downforce at any speed. Tesla’s patent, which we covered last year, describes fans and deployable skirts that create sealed or partially sealed regions under the car, with the fans extracting air to lower the pressure and increase grip and stability.
Still processing this … the most unreal thing I’ve seen. https://t.co/HtEuvnkZjY

Tesla pairs that with active wings, a next generation steer by wire system and a Track Mode that lowers the car and changes the suspension, with high downforce and low drag settings for the circuit. To keep weight down, Tesla points to magnesium, titanium and carbon fiber, manual controls and a fixed seat position, which it says lets the car respond to driver inputs almost instantly.
Tesla Roadster: Three configs, one can fly, 0-60 in 0.8 seconds
The cold gas thrusters are the other half. On the Thrust version they sit at the rear and Tesla says they take the car from 0 to 60 mph in under 0.9 seconds, while the Rocket version adds perimeter thrusters for forward, upward and lateral rotational movement. Tesla says the all electric actuators make micro adjustments within a fraction of a second.

Musk has been talking about records for years. In June 2019 he said, “We’re going to do things with the new Roadster that are kind of unfair to other cars.” That September, when a follower asked whether the Roadster would beat the Nürburgring production car record, he replied with one word, “Absolutely,” as we reported at the time. In February 2024 he said Tesla had “radically increased the design goals” for the car and that its sub one second 0 to 60 time would be “the least interesting part.”
There are caveats. Tesla has not published a lap time or a verified cornering figure, so the record talk is still a promise rather than a result. Tesla also says the car is not approved for public road use, and the thruster features are limited to the Rocket trim, which is invite only. Fan cars have also been banned or withdrawn before, and getting a sealed underbody to work on a rough public road is a harder problem than on a smooth track. The first real test will be an official lap at a circuit.
