Bob Lutz Is Right about Tesla’s Home Battery Solution
Last week on CNBC, maximum Bob Lutz took aim at Tesla Motors and, specifically, the Powerwall product offering. Lutz says, “I think [the battery] is greatly overvalued because having batteries as backup storage has been around for hundreds of years. I can’t understand the fascination with this.”
Maximum Bob is right on the mark, the Powerwall is overvalued by the media. The two home products, 10kWh (the backup battery) and the 7kWh daily cycle, will make up a small portion of the revenue mix for Tesla.
Musk even said so at the annual shareholder meeting. In response to a question about the powerwall, Musk said,“Actually it’s probably worth also elaborating on the Powerpack which we expect most of our activities to be with the Powerpack, not the Powerwall.”
“So, it’s probably 80%, maybe more than that of our total energy sales likely to be at the Powerpack level to utilities and to large industrial customers.”
However, the only problem for maximum Bob is that he keeps on speaking without mentioning the powerpack potential or he doesn’t understand it. Or maybe it’s a narrative for CNBC to milk, since Bob is a CNBC contributor. I enjoy Uncle Bob, but he’s a one-trick pony, Automotive guy.
Industrial and utilities are the big catch here and there’s no waiting for an energy market in this space. It’s here and Musk and JB Straubel are really smart, but how smart?
Musk on how the powerpack can assimilate in the utility space:
So, you can take our Powerpacks and they are compact enough to fit in an existing substation. This is a very big deal because it means that they do not have to create an new substation or expand the existing substation because in most neighborhoods in order for them to do that they would have to buy someone’s house and level it and put a new substation and then the neighbors do not like that.
I guess that’s why Tesla didn’t go for the bulky, lead acid batteries solution that Lutz advocated on the “Squawk Box” segment. To be fair, maximum Bob was talking about a home battery solution.
So, the utilities will have a plug-n-play product that will be able to put power on the grid quickly at the local level, without having to build out any new infrastructure. I wonder if the utilities will say thanks?
Plus, there will be a healthy supply of customers in the industrial manufacturing space, too. I’ve been writing for Automation World magazine since 2008 and energy management has been a growing issue for manufacturers and those companies love plug-n-play solutions.
For example Cummins Inc., a manufacturer of truck engines, could be a candidate for the Powerpack. They just installed 7,200 solar panels and 2-megawatts of solar power at its Pennsylvania plant. Currently, Cummins sells it back to the utilities but a Powerpack solution could help them avoid large demand charges for heavy use in the afternoon, say during large production times.
Sure, Tesla Energy has to execute and utilities have to come on board. However, it’s getting there. Listen to a couple Energy Gang podcasts and you hear about utility infrastructure buildout costs, and utilities bemoaning that it will be selling less energy to retailers.
It looks like Elon has worked all this out for the utilities, first, the infrastructure and, secondly, the energy demand component. If Tesla produces 500,000 electric cars annually in, say, five or six years, then you have a big demand for energy and for the utilities. That’s a lot of juice.
Then, maybe maximum Bob will see the “fascination” with battery storage.

Tesla analyst realizes one big thing about the stock: deliveries are losing importance
Tesla analyst Dan Levy of Barclays realized one big thing about the stock moving into 2026: vehicle deliveries are losing importance.
As a new era of Tesla seems to be on the horizon, the concern about vehicle deliveries and annual growth seems to be fading, at least according to many investors.
Even CEO Elon Musk has implied at times that the automotive side, as a whole, will only make up a small percentage of Tesla’s total valuation, as Optimus and AI begin to shine with importance.
He said in April:
“The future of the company is fundamentally based on large-scale autonomous cars and large-scale and large volume, vast numbers of autonomous humanoid robots.”
Almost all of Tesla’s value long-term will be from AI & robots, both vehicle & humanoid
— Elon Musk (@elonmusk) September 11, 2023
Levy wrote in a note to investors that Tesla’s Q4 delivery figures “likely won’t matter for the stock.” Barclays said in the note that it expects deliveries to be “soft” for the quarter.
In years past, Tesla analysts, investors, and fans were focused on automotive growth.
Cars were truly the biggest thing the stock had to offer: Tesla was a growing automotive company with a lot of prowess in AI and software, but deliveries held the most impact, along with vehicle pricing. These types of things had huge impacts on the stock years ago.
In fact, several large swings occurred because of Tesla either beating or missing delivery estimates:
- January 3, 2022: +13.53%, record deliveries at the time
- January 3, 2023: -12.24%, missed deliveries
- July 2, 2024: +10.20%, beat delivery expectations
- October 3, 2022: -8.61%, sharp miss due to Shanghai factory shutdown
- July 2, 2020: +7.95%, topped low COVID-era expectations with sizeable beat on deliveries
It has become more apparent over the past few quarters that delivery estimates have significantly less focus from investors, who are instead looking for progress in AI, Optimus, Cybercab, and other projects.
These things are the future of the company, and although Tesla will always sell cars, the stock is more impacted by the software the vehicle is running, and not necessarily the vehicle itself.

SpaceX IPO is coming, CEO Elon Musk confirms
However, it appears Musk is ready for SpaceX to go public, as Ars Technica Senior Space Editor Eric Berger wrote an op-ed that indicated he thought SpaceX would go public soon. Musk replied, basically confirming it.
Elon Musk confirmed through a post on X that a SpaceX initial public offering (IPO) is on the way after hinting at it several times earlier this year.
It also comes one day after Bloomberg reported that SpaceX was aiming for a valuation of $1.5 trillion, adding that it wanted to raise $30 billion.
Musk has been transparent for most of the year that he wanted to try to figure out a way to get Tesla shareholders to invest in SpaceX, giving them access to the stock.
He has also recognized the issues of having a public stock, like litigation exposure, quarterly reporting pressures, and other inconveniences.
However, it appears Musk is ready for SpaceX to go public, as Ars Technica Senior Space Editor Eric Berger wrote an op-ed that indicated he thought SpaceX would go public soon.
Musk replied, basically confirming it:
As usual, Eric is accurate
— Elon Musk (@elonmusk) December 10, 2025
Berger believes the IPO would help support the need for $30 billion or more in capital needed to fund AI integration projects, such as space-based data centers and lunar satellite factories. Musk confirmed recently that SpaceX “will be doing” data centers in orbit.
AI appears to be a “key part” of SpaceX getting to Musk, Berger also wrote. When writing about whether or not Optimus is a viable project and product for the company, he says that none of that matters. Musk thinks it is, and that’s all that matters.
It seems like Musk has certainly mulled something this big for a very long time, and the idea of taking SpaceX public is not just likely; it is necessary for the company to get to Mars.
The details of when SpaceX will finally hit that public status are not known. Many of the reports that came out over the past few days indicate it would happen in 2026, so sooner rather than later.
But there are a lot of things on Musk’s plate early next year, especially with Cybercab production, the potential launch of Unsupervised Full Self-Driving, and the Roadster unveiling, all planned for Q1.

Tesla Full Self-Driving statistic impresses Wall Street firm: ‘Very close to unsupervised’
The data shows there was a significant jump in miles traveled between interventions as Tesla transitioned drivers to v14.1 back in October. The FSD Community Tracker saw a jump from 441 miles to over 9,200 miles, the most significant improvement in four years.
Tesla Full Self-Driving performance and statistics continue to impress everyone, from retail investors to Wall Street firms. However, one analyst believes Tesla’s driving suite is “very close” to achieving unsupervised self-driving.
On Tuesday, Piper Sandler analyst Alexander Potter said that Tesla’s recent launch of Full Self-Driving version 14 increased the number of miles traveled between interventions by a drastic margin, based on data compiled by a Full Self-Driving Community Tracker.

The data shows there was a significant jump in miles traveled between interventions as Tesla transitioned drivers to v14.1 back in October. The FSD Community Tracker saw a jump from 441 miles to over 9,200 miles, the most significant improvement in four years.
Interestingly, there was a slight dip in the miles traveled between interventions with the release of v14.2. Piper Sandler said investor interest in FSD has increased.
Full Self-Driving has displayed several improvements with v14, including the introduction of Arrival Options that allow specific parking situations to be chosen by the driver prior to arriving at the destination. Owners can choose from Street Parking, Parking Garages, Parking Lots, Chargers, and Driveways.
Additionally, the overall improvements in performance from v13 have been evident through smoother operation, fewer mistakes during routine operation, and a more refined decision-making process.
Early versions of v14 exhibited stuttering and brake stabbing, but Tesla did a great job of confronting the issue and eliminating it altogether with the release of v14.2.
Tesla CEO Elon Musk also recently stated that the current v14.2 FSD suite is also less restrictive with drivers looking at their phones, which has caused some controversy within the community.
Although we tested it and found there were fewer nudges by the driver monitoring system to push eyes back to the road, we still would not recommend it due to laws and regulations.

With that being said, FSD is improving significantly with each larger rollout, and Musk believes the final piece of the puzzle will be unveiled with FSD v14.3, which could come later this year or early in 2026.
Piper Sandler reaffirmed its $500 price target on Tesla shares, as well as its ‘Overweight’ rating.
