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.

In a new note to investors on Tuesday, Morgan Stanley analyst Andrew Percoco said that Tesla has one big financial question to answer for investors regarding its Robotaxi rollout, Full Self-Driving software, and Optimus.
Percoco said in the note that, for the most part, investors are still very positive about the direction the company is headed. However, there are some things the firm would like to see, and they have to do with financials.
Tesla (TSLA) Q2 2026 earnings results: miss on EPS, beat on revenue
Tesla bulls are more than convinced that the company’s Full Self-Driving software is proof it can develop physical AI. Financially, however, there are still some questions, especially on elevated spending, which CEO Elon Musk said would occur as the company works to roll out Robotaxi faster and continue developing its Optimus robot.
The latter two are where Tesla will have to prove progress to investors, as Percoco writes that both projects “will require clearer evidence that Robotaxi is scaling and more tangible Optimus proof points to support the ROI on elevated capex.”
Percoco said the second quarter earnings call did not change his long-term thesis of where Tesla is positioned in the AI race, which is out in front. However, there are concerns that weaker gross margins and higher R&D spend will stress financials, and that has “sharpened our (and investors’) focus on measurable progress across Robotaxi and Optimus.”
Additionally, Robotaxi still needs to be proven with more operation in existing cities while maintaining safety but improving how many rides it gives in any given time, he said. For Optimus, Percoco wrote that he is “still looking for evidence beyond commentary around SOP.”

Morgan Stanley put Percoco in charge of covering Tesla after long-time analyst Adam Jonas transitioned to the automotive side.
Currently, Morgan Stanley has a $415 price target on Tesla and a ‘Hold’ rating on the stock. It is trading at around $330 at the time of publication, which was 2:30 P.M. on the East Coast.
SpaceX’s massive investment in AI will make it a big winner, Argus Research said after the company’s successful earnings call last week.
The firm also upgraded shares to a Buy from Hold and set a $160 price target.
SpaceX (NASDAQ: SPCX) is currently recovering from its heavy AI infrastructure investments, as it spent nearly $16 billion in Q2 alone. The company did this primarily by monetizing high-demand GPU compute capacity at a much faster pace than traditional data center economics would suggest.
Company CFO Bret Johnsen said that SpaceX would be able to pay back anything on new deployments within a year.
There are plenty of ways the company can do this:
Leasing excess compute capacity through contracts
SpaceX has already built Colossus and Colossus II, largely for its own model training. However, much of that capacity is already rented out to third parties. It already has major deals with Anthropic, Google, and Reflection AI. These partnerships are adding billions per month to SpaceX’s spreadsheet.
-
High utilization driven by industry-wide scarcity
The demand for advanced AI training and inference capacity continues to exceed what is available for use. SpaceX can fill new racks quickly after they come online, so the capital deployed converts into revenue with minimal idle time.
Additionally, management and outside observers have described the new compute capital as behaving more like a cost-of-goods-sold than traditional multi-year capex, especially because of this rapid monetization pattern.
Capacity has already scaled from ~0.4 GW a year to 1.4 GW annually by the end of Q2. There are targets of more than 2 GW by year-end.
High incremental margins on the rental business once capacity is online
GPU cloud providers often operate at strong gross margins. SpaceX can monetize capacity that was already partially built or can be added efficiently. This means that incremental EBITDA margins on the rental revenue are usually high. This accelerates cash recovery relative to the gross capital outlay.
Parallel monetization of its own AI software and applications
Beyond pure infrastructure rental, SpaceX also generates revenue from Grok through subscriptions and usage, from X through ads, data, and other related services, enterprise APIs, and the planned integration of the Cursor coding tools acquisition.
These application layers ride on the same compute infrastructure and provide additional high-margin streams that could offset build-out costs. AI-segment revenue overall rose sharply to about $2.6 billion in Q2, according to Motley Fool. This was driven primarily by the infrastructure contracts, but the software side is also partially responsible.
Efficient, large-scale deployment and vertical integration advantages
SpaceX has emphasized the rapid construction of power and cooling infrastructure and favorable cost-per-megawatt economics relative to industry benchmarks in some disclosures.
-
Combined with its ability to scale capacity aggressively and the fact that many contracts start generating revenue within months of capacity coming online, the effective payback compresses dramatically compared with more conventional multi-year data-center projects.
SpaceX’s dominant near-term recovery path will turn the AI clusters into a hyperscale-style compute rental business for other leading AI companies while still using a portion for internal models.

Another Tesla SpaceX merger prediction by ARK Invest has Elon Musk talking
Elon Musk again denies a Tesla China split as new SpaceX merger speculation resurfaces quickly.
Elon Musk restated that Tesla has no plans to separate its China business from the rest of the company, responding to a new round of merger speculation from ARK Invest.
On the firm’s “Brainstorm” podcast, Cathie Wood’s team, including chief futurist Brett Winton and research director Nick Grous, argued a Tesla and SpaceX combination remains likely, with an announcement possible before the end of the year even if the deal itself would not close that quickly. Winton called Tesla’s Shanghai operations a “small ish wrinkle” for a merger rather than a real obstacle, since SpaceX’s national security work with the U.S. government sits uneasily next to Tesla’s manufacturing base in China.
Musk pushed back on the framing directly. “China is awesome. I strongly encourage people to visit,” he wrote on X. He also repeated language he first used in late July, when the Wall Street Journal reported that Tesla executives had been told to prepare for a possible spinoff, sale, or closure of the China business ahead of a SpaceX tie up. Musk called that report “absurdly fake news” at the time, adding that a separation had “never even come up in a discussion ever,” a line he echoed again this week.
The repeated denial has not settled the underlying question, because Shanghai’s role in Tesla’s business is exactly what makes a merger complicated. Gigafactory Shanghai still ships more than half of Tesla’s global deliveries and functions as the company’s main export hub for Europe and Asia. Teslarati previously reported on Musk’s initial denial, and the merger conversation itself has been building since SpaceX’s IPO gave it public shares to use as acquisition currency.
Wedbush’s Dan Ives has pegged the odds of a Tesla SpaceX merger at 80 to 90 percent by early 2027, and ARK’s prediction of a year end announcement adds another data point to that timeline, even as Musk keeps rejecting the specific mechanics reporters have described. Neither position rules out the other. Musk can deny a China spinoff was ever discussed while analysts still expect some form of combination to move forward, since ARK and Ives are both describing convergence at the corporate level, not necessarily the internal restructuring the Journal described in July.
For now, Tesla’s China business remains intact, and Musk’s comments this week make clear he has no interest in publicly walking that position back, no matter how often the merger question resurfaces.
