Tesla Bioweapons Defense Mode

Make no mistake about it, the climate control system for the Model X is superior to anything available from any other manufacturer and will do an excellent job of protecting its occupants from harmful elements in the atmosphere. Tesla describes the system this way, “The biodefense button is designed to allow clean medical-grade air into the cabin and keep contaminated air out. When deployed, it pushes the system into full fresh mode, pulling all HVAC air through the HEPA filter. The fan goes to max speed 11, pulling in enough air to slightly pressurize the cabin, keeping other air from entering Model X.”

But a few people with actual bioweapons experience quibble with the Tesla Bioweapons Defense Mode claims. The issue is not whether the system works, but whether its claims regarding viruses are accurate.

Colonel Randall Larsen, retired from the U.S. Air Force and now the director of the Institute for Homeland Security, tells Gizmodo that he is actually a Tesla fan. “I’m actually building a new house, and I had them put an electrical charger in the garage, just in case I buy a Tesla,” he says. But when told about the Tesla Model X “bioweapon defense mode” he laughed out loud and asked, “So, is Musk actually advertising this?”

To be considered a real HEPA filter, an air filter has to remove 99.97% of 0.3 micrometer particles from the air. That’s fine enough to catch bacteria like anthrax. It will also stop the plague and most other bacteria, as well as most pollen, dust, and fungal spores. “Now, if you’re worried about bacterial agents like anthrax or plague, a good filtering system would probably protect you,” says Larsen.

But viruses are much smaller than bacteria, which means they’re harder to filter out of the air. “Well, 0.3 micrometer won’t hold back viruses. It will hold back most bacteria, but it won’t hold back viruses. So, if you believe that all bio-terrorist agents are bacteria, then you’ll get an increment of protection,” said Michael J. Buchmeier, deputy director of the Pacific Southwest Regional Center for Biodefense and Emerging Diseases at the University of California, Irvine.

The influenza A virus is only 120 nanometers wide, so it can pass through even a 0.2 micrometer HEPA filter without a problem. “It’s a statistical game that we play,” said Buchmeier. “Any filter like that is going to be efficient to a degree but it’s not necessarily 100% efficient.”

Larsen and Buchmeier also point out that, by the time the passengers realize there has been a bioweapons attack, it will probably be too late to take protective action. “The key problem with the bio is knowing when it’s been released,” Buchmeier says. “You know, it’s not like there’s a big bang or something. It’s a pretty extravagant long shot anyway, you know, the idea that you’re going to be forewarned enough to implement this filter in time to prevent any exposure.”

None of which should take away from how good the Model X climate control system is at protecting its passengers. It can filter out allergens like ragweed and cedar pollen, fungal spores like the ones that cause Valley Fever, and irritants like smoke and dust. It could also filter out unpleasant roadside odor. “There are a lot of reasons why you would put a filter like that in, and only one of them is bioterrorism,” says Buchmeier.

Tesla receives European Ecolabel (EMAS) seal for Giga Berlin-Brandenburg

The EMAS seal highlights Tesla’s existing environmental measures in the facility.

Tesla has been awarded the European Ecolabel (EMAS) seal for Gigafactory Berlin-Brandenburg. 

The EMAS seal highlights Tesla’s existing environmental measures in the facility, such as extensive reforestation efforts and reduced water usage. It also emphasizes Tesla’s commitment to improve its environmental initiatives.

Giga Berlin’s environmental initiatives

The EMAS (Eco-Management and Audit Scheme) seal is a long-term environmental management system that focuses on compliance with regulations and improving environmental performance, as noted in a Tagesspiegel report.

Plant manager André Thierig noted that Tesla has already planted over 2 million trees to replace the trees that have been felled to make way for Giga Berlin. Tesla is also targeting an additional 5 to 15 MW peak solar capacity this year to make the plant more sustainable. “We will continue to promote photovoltaics in the future,” he said.

Giga Berlin’s consumption and energy use

In 2024, Giga Berlin consumed about 419,503 MWh of energy, with electricity accounting for more than half, followed by natural gas. The facility is looking to lower natural gas use by redirecting the use of process heating water via waste heat. Water consumption was listed at 2.16 cubic meters per vehicle, significantly below the industry average of 3.5.

This year, Tesla Giga Berlin is looking to recycle 90% of the Model Y plant’s process wastewater. Around 11,000 employees currently work at Giga Berlin, which produces 5,000 vehicles per week or roughly 250,000 units annually.

Certification welcomed but not without criticism

The EMAS program requires companies to disclose resource use, emissions, and improvement plans. Over 40 companies in Brandenburg have EMAS certification.

Brandenburg’s Environment Minister Minister Hanka Mittelstädt (SPD) described Tesla as a role model for the region. “Everything is public, and that also creates a certain amount of trust,” she said, noting that Tesla is a “beacon” in the industry.

Monique Zweig, Managing Director of the East Brandenburg Chamber of Industry and Commerce (IHK), shared her optimism in a comment to rbb24. “At Tesla, you can see that climate goals go hand in hand with industry,” Zweig stated.

Unsurprisingly, local activists expressed skepticism. The Association for Nature and Landscape in Brandenburg, which is against Tesla, questioned whether the certification could be used as “greenwashing.”

The group also alleged that the certificate could pave the way for weaker oversight for the EV maker. “The seal is ‘greenwashing’ to portray the company as more environmentally friendly,” spokesperson Steffen Schorcht noted.

I traded my ICE vehicle for a Tesla Model Y: here’s how it went

After working at Teslarati for six years and covering the EV space nearly every single day (I recently published my 5,000th article on here), I figured it was time to make a switch.

I recently decided, after a variety of things, that I was going to trade in my internal combustion engine (ICE) vehicle for a new Tesla Model Y. It was a long time coming.

After working at Teslarati for six years and covering the EV space nearly every single day (I recently published my 5,000th article on here), I figured it was time to make a switch. Over the past few years, there have been days when I would have been better off with an EV, but my Summer and Winter activities, as well as the price, kept me from making the switch.

Recently, I decided that it was time. My 2021 Ford Bronco Sport had been experiencing a number of issues, none major, but numerous sensor replacements. It was an affordable and fun car, but after fixing the Tire Pressure Monitoring System in the front right tire, an EVAP switch valve in the motor two months ago, and some other things, the Bronco became more of a chore (and a drain on my wallet) than anything.

With the timing of the $7,500 tax credit expiring and a substantial amount of positive equity in my Bronco, I knew it was time. My experience was excellent, but I would like to share some insights with our readers about the entire process, which may also help you make the jump. Others were more of a one-time thing, as they were things customers would only deal with as the tax credit went away.

My Decision

I knew I was going to get a Tesla, and my inability to enjoy a good sedan steered me to a Model Y (no hate toward the Model 3, it’s just not for me). I knew with the weather in Pennsylvania, all-wheel drive was a need, and the price difference between the rear-wheel-drive and AWD configurations of the Y made it a no-brainer.

Plus, I really would like to get this thing out on the beach, something I’ve done every Summer since buying the Bronco with my Fiancè.

I actually ordered this car back in June, but ended up canceling the reservation to wait until the end of Summer. I ended up ordering the car I took delivery of on Saturday back on my birthday on August 16.

I was looking for Diamond Black with White Interior, and it was available in Pittsburgh for delivery. However, I really love the team at Tesla Mechanicsburg, so I opted to do a Black on Black Model Y that was a Fremont build, so I could pick it up from the guys up there. The interior color was not a dealbreaker for me. I just wanted to take delivery soon.

I ordered from inventory, which is not something that is possible now. There is no new Model Y inventory within 200 miles of me, a good sign for Tesla but a bad sign if you’re looking to buy something before the quarter ends. Luckily, the IRS is allowing people to enter an agreement for a car, so you could technically build the car of your choice, put a down payment on it, and take delivery after the September 30 cutoff.

Tesla Delivery Day

My appointment was at 12 p.m. and I arrived about ten minutes before. The team greeted me quickly, and I was able to walk right up and see my car with my name on it. It was pretty incredible and a feeling I have not felt in a long time. I’ll be honest, when I bought the Bronco, I never thought I’d own one. When I got one, it felt pretty surreal.

I felt that way yesterday. It was really cool to finally buy a car that I’d only dreamed of owning. It’s not the only car I dream of owning in my lifetime, but it is one I knew I wanted right now. Now that I was showing up to buy it, it really felt surreal.

The process was really fast and efficient, and I could have been in and out in ten minutes if I wanted to. However, I hung around and talked to the guys there; they discussed some good accessories I should consider and suggested some tint.

I was on my way.

My First Drive and What to Expect

I stopped by my Fiancè’s work, showed her the new ride, brought her some lunch, and headed home to my pup. So far, I’ve driven about 60 miles, with most of it being done manually and about 10 miles using Full Self-Driving. I’ve enjoyed driving it myself so much as of right now, but I know FSD will come in handy plenty in the coming months.

In the future, I plan to explore a wide range of topics as an owner. I do not currently have home charging, which is something that many people believe is a dealbreaker for owning an EV. I have two Superchargers very close to my place, so I’m not too concerned about it.

I have been in touch with my leasing office about installing a charger or chargers for the past few months, which seems like it could happen early next year.

So far, I’m really happy with how everything has worked out.

It appears that Tesla has created something special with the new Model Y Performance. The vehicle, which was released earlier late August, has started receiving rave reviews, some of it even from publications that tend to be critical of the EV maker and CEO Elon Musk.

Model Y Performance impressions

Swedish automotive outlet CarUp.se has given the updated Tesla Model Y Performance high marks, highlighting its redesigned sport seats as a standout improvement. Tesla implemented a number of key improvements to the Model Y Performance, such as its redesigned sports seats, which now feature powered thigh extensions like those found in the Model Y L from China.

To summarize, its review, the publication noted that “In addition to making you sit like a king, (the Model Y Performance) is also extremely fast at red lights.”  The publication highlighted that “the exterior of the Tesla quickly reveals that it is a Tesla Performance model and there is no doubt that it is a really good-looking electric car.” This is quite impressive considering that the previous-generation Model Y Performance looked quite tame compared to the Model S and X Plaid and the Model 3 Performance.

Tweaks and improvements

The refreshed Model Y Performance model receives unique bumpers, red brake calipers, new wheels, and a carbon fiber spoiler, which together give the crossover a more athletic appearance. Performance badging and projection lighting further distinguish it from other Model Y variants. Inside, the upgraded front sport seats deliver noticeably improved support compared to the standard version, enhancing the vehicle’s balance of comfort and sportiness.

The new Model Y Performance deliver 460 horsepower and a top speed of 250 km/h, while consumption is listed at 16.2 kWh/100 km and range at 580 km WLTP. The crossover also benefits from adaptive suspension with preset damping modes. Manufactured at Gigafactory Berlin-Brandenburg, the Model Y Performance is currently available in Europe and the Middle East, with deliveries expected to start in the next 1-2 months.
