While undergoing its commissioning process in late September, a fire broke out in one of the Tesla Megapacks at the Bouldercombe big battery in Queensland, Australia. The fire triggered debates about the viability of renewable energy solutions, as well as the safety of battery storage systems. 

The fire was not severe, with Genex Power, the owner of the battery storage system, stating that the fire did not even necessitate the use of water at all. Genex CEO Craig Francis also noted that the isolated nature of the fire suggests that the incident would not have any significant impact on the Bouldercombe big battery. 

And as per an announcement from Genex Power, the fire actually did not start at the Megapack’s battery modules. Instead, the fault initially occurred on the AC side of the impacted Megapack unit. The fault then propagated to the battery modules within the Megapack. This was determined following an analysis of the incident by Tesla, Genex, and other stakeholders.

“The preliminary RCA indicates that a fault occurred on the AC side of the Megapack unit. The fault then propagated to the battery modules within the Megapack. The burn of the Megapack followed design and certification testing expectations under UL9540A, with no external water required, and no propagation of the active fire to adjacent Megapack units or balance of plant. 

“The failure has been isolated to the power electronics interface with the AC bus bar in the individual Megapack unit itself and not the broader installation of Megapack units. In order to mitigate against a further event, Tesla will be undertaking replacement of two identified power electronics units and out of caution, physical inspection of the power electronics within the remainder of units at the Project site. Genex will also be implementing upgrades to breaker control setting response times to further mitigate against a potential future event,” Genex wrote.

While the minor fire affected one Megapack battery in the Bouldercombe site, the Megapack adjacent to the impacted unit also suffered minor thermal damage to its electrical insulation. Thus, Tesla would be providing two Megapacks to replace the two units that were damaged by the fire. The Megapacks are already en route to the site, and are expected to arrive in early December 2023, as noted in a PV Magazine Australia report.

Elon Musk’s The Boring Company has officially closed submissions for its Tunnel Vision Challenge, confirming that a total of 487 entries were received before the deadline.

In a post on X, the company wrote, “Tunnel Vision Challenge is closed! 487 entries received – TBC team is excited to go through them all!” The company added that “We will select the top ~15 in the next week, and reach out with follow-up questions,” and that an “overall winner will be announced on March 23.”

The Tunnel Vision Challenge invited individuals, companies, and governments to propose a tunnel project up to one mile long with a 12-foot inner diameter. The winning entry will have its tunnel constructed free of charge.

Submissions could range from Loop passenger tunnels to freight, pedestrian, utility, or water tunnels. The only requirement was that the project clearly demonstrate how tunneling would meaningfully improve transportation or infrastructure between two points.

Just days before the deadline, the company provided an interim update noting that 407 entries had already been received. “Update on the Tunnel Vision Challenge – 1 mile of free tunnel! With 3 days left to submit, 407 entries have been received. Great to see enthusiasm for tunnels!” The Boring Company wrote at the time on X. By the close of submissions, the total had grown closer to 500 entries, hinting at strong interest in underground transportation solutions.

Entries are being evaluated on usefulness, stakeholder engagement, and technical, economic, and regulatory feasibility. Applicants were required to quantify projected benefits, such as time saved per rider or cost savings per shipment, and provide maps showing proposed alignments and other details. Submissions that included geotechnical or subsurface data are expected to receive additional consideration.

The Boring Company will fund the tunnel’s construction itself, though related infrastructure costs may be discussed with the winning team. The company also retains discretion to modify or cancel the challenge.

Tesla confirms date when new Cybertruck trim will go up in price

Tesla has officially revealed that this price will only be available until February 28, as the company has placed a banner atop the Design Configurator on its website reflecting this.

Tesla has confirmed the date when its newest Cybertruck trim level will increase in price, after CEO Elon Musk noted that the All-Wheel-Drive configuration of the all-electric pickup would only be priced at its near-bargain level for ten days.

Last week, Tesla launched the All-Wheel-Drive configuration of the Cybertruck. Priced at $59,990, the Cybertruck featured many excellent features and has seemingly brought some demand to the pickup, which has been underwhelming in terms of sales figures over the past couple of years.

Tesla launches new Cybertruck trim with more features than ever for a low price

When Tesla launched it, many fans and current owners mulled the possibility of ordering it. However,  Musk came out and said just hours after launching the pickup that Tesla would only keep it at the $59,990 price level for ten days.

What it would be priced at subsequently was totally dependent on how much demand Tesla felt for the new trim level, which is labeled as a “Dual Motor All-Wheel-Drive” configuration.

Tesla has officially revealed that this price will only be available until February 28, as the company has placed a banner atop the Design Configurator on its website reflecting this:

Many fans and owners have criticized Tesla’s decision to unveil a trim this way, and then price it at something, only to change that price a few days later based on how well it sells.

It seems the most ideal increase in price would be somewhere between $5,000 and $10,000, but it truly depends on how many orders Tesla sees for this new trim level. The next step up in configuration is the Premium All-Wheel-Drive, which is priced at $79,990.

The difference between the Dual Motor AWD Cybertruck and the Premium AWD configuration comes down to towing, interior quality, and general features. The base package is only capable of towing up to 7,500 pounds, while the Premium can handle 11,000 pounds. Additionally, the seats in the Premium build are Vegan Leather, while the base trim gets the textile seats.

It also has only 7 speakers compared to the 15 that the Premium trim has. Additionally, the base model does not have an adjustable ride height, although it does have a coil spring with an adaptive damping suspension package.

Tesla set to activate long-awaited Cybertruck feature

Tesla will officially activate the Active Noise Cancellation (ANC) feature on Cybertruck soon, as the company has officially added the feature to its list of features by trim on its website.

Tesla is set to activate a long-awaited Cybertruck feature, and no matter when you bought your all-electric pickup, it has the hardware capable of achieving what it is designed to do.

Tesla simply has to flip the switch, and it plans to do so in the near future.

Tesla will officially activate the Active Noise Cancellation (ANC) feature on Cybertruck soon, according to Not a Tesla App, as the company has officially added the feature to its list of features by trim on its website.

Tesla rolls out Active Road Noise Reduction for new Model S and Model X

The ANC feature suddenly appeared on the spec sheet for the Premium All-Wheel-Drive and Cyberbeast trims, which are the two configurations that have been delivered since November 2023.

However, those trims have both had the ANC disabled, and although they are found in the Model S and Model X, and are active in those vehicles, Tesla is planning to activate them.

In Tesla’s Service Toolbox, it wrote:

ANC software is not enabled on Cybertruck even though the hardware is installed.”

Tesla has utilized an ANC system in the Model S and Model X since 2021. The system uses microphones embedded in the front seat headrests to detect low-frequency road noise entering the cabin. It then generates anti-noise through phase-inverted sound waves to cancel out or reduce that noise, creating quieter zones, particularly around the vehicle’s front occupants.

The Model S and Model X utilize six microphones to achieve this noise cancellation, while the Cybertruck has just four.

Tesla Cybertruck Dual Motor AWD estimated delivery slips to early fall 2026

As previously mentioned, this will be activated through a software update, as the hardware is already available within Cybertruck and can simply be activated at Tesla’s leisure.

The delays in activating the system are likely due to Tesla Cybertruck’s unique design, which is unlike anything before. In the Model S and Model X, Tesla did not have to do too much, but the Cybertruck has heavier all-terrain tires and potentially issues from the aluminum castings that make up the vehicle’s chassis, which are probably presenting some challenges.

Unfortunately, this feature will not be available on the new Dual Motor All-Wheel-Drive configuration, which was released last week.
