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.

SpaceX to report first-ever earnings today: here’s what to expect
Elon Musk’s space exploration company, SpaceX (NASDAQ: SPCX), is set to report its earnings for the second quarter today in what will be its first-ever earnings call since going public in July.
SpaceX is trading down roughly 25 percent from its IPO. These early stock signals are usually a bit tumultuous, and considering this is the first company actively launching rockets that is available on the stock exchange, investors might have a tendency to be a bit skittish.
However, there are going to be some details that investors will hear for the first time today on the earnings call. Here’s what to look for:
Wall Street Expectations
Revenue is expected to fall somewhere around $6.8 billion, and will be heavily driven by Starlink, which is SpaceX’s widely popular satellite internet platform that has been adopted by numerous airlines, cruise ships, and other maritime operations. It is also available for consumers at home or in their cars.
Earnings Per Share (EPS) expectations fall at a net loss of $0.23 per share. Wall Street sees this as a total net loss of roughly $1.9 billion.
EBITDA is expected to come in between $2 billion and $2.1 billion.
What Investors Want to Know
Tesla uses the Say platform to help work with both retail and institutional investors to answer relevant and quality questions that address concerns or questions that they might have.
However, SpaceX is doing things differently, as the company launched its own Investor Relations website where these questions are being fielded. Just like the Tesla questions, they seem to be less focused on the operational tasks and overall progress of the company, and more novelty.
Here are the top five:
- Has the team thought about what possibilities there are with your mascot Asteroid? Whether it’s starting additional foundations for kids in its name, helping kids learn about space, etc. Kids are our future, and Asteroid would be a fun and easy way to help.
- Baby Asteroid is already making a difference through charity around the world. Could SpaceX take it even further with programs that inspire kids to explore space?
- SpaceX has some legendary vehicle names. Would you ever allow the public to name a Starship, even knowing there is a 99% chance it becomes Shipy McShipface?
- When can we expect to see more footage of the Human Landing System?
- Will Asteroid (your mascot) go to Mars?
SpaceX will report its earnings today, August 4, at 4:30 P.M. EDT.

SpaceX’s biggest test yet arrives this week and it’s not a rocket launch
SpaceX will report second quarter results after the market closes on Tuesday, August 4, marking the first time the company has opened its books to the public since its record IPO in June. Management will host a live audio only webcast at 4:30 p.m. ET, streamed on X, with no dial in option.
The debut carries more weight than a typical first quarter as a public company. Two trading days after the release, on August 6, the first tranche of SpaceX’s lockup expires, freeing roughly 911.5 million insider and employee shares, worth well over $100 billion at current prices and the largest such release in Wall Street history. A second, larger tranche tied to the stock trading 30 percent above its $135 IPO price never triggered, since shares have spent most of July trading below that price.
Wall Street’s models point to revenue near $6.9 billion for the quarter, up sharply from the $4.69 billion SpaceX reported in the first quarter, with a narrower per share loss than the $1.27 posted three months earlier, according to estimates compiled by Motley Fool. Those numbers will be the first look at how SpaceX’s three segments, Starlink, launch and AI, are performing independently.
SpaceX scores another massive Pentagon deal to support military satellites
Investors heading into the call have a specific list of questions. How many net new Starlink subscribers did SpaceX add after ending March with 10.3 million, and is average revenue per user holding up as the service expands into lower income markets. How much of the AI segment’s revenue reflects contract signings with Anthropic, Google and Reflection AI this year, deals that combined could annualize to nearly $28 billion if fully ramped. Whether capital expenditures, which nearly doubled in the AI segment alone between 2024 and 2025, are still accelerating or starting to plateau. And whether management offers any forward guidance at all, something SpaceX has never done publicly.
The report will also land days after Elon Musk publicly denied a Wall Street Journal report describing internal planning to separate Tesla’s China business ahead of a potential Tesla-SpaceX merger. Whether Musk or SpaceX executives address that speculation on the call, even indirectly, maybe something investors will be listening for on Tuesday.
As Teslarati reported after Musk’s own warning to short sellers last week, the CEO has made clear he expects skeptics to be proven wrong over time. Tuesday will be the first chance for the numbers themselves to make that case.

Tesla AI boss reveals how big Optimus is going to get
Tesla’s Optimus chief corrected himself on X, confirming a staggering 10 million robot production target.
Tesla’s Optimus program has a new number attached to it, after Ashok Elluswamy, the executive who has run the humanoid robot program since June 2025, posted a three word correction on X Thursday, “Correction, 10 million robots.”
The line clarifies the long term annual capacity Tesla is building toward its planned second Optimus production line at Gigafactory Texas, a figure Musk has cited repeatedly since last year’s shareholder meeting.
The scale is worth noting, because ten million robots a year would mean Tesla building more units annually than most countries sell in new cars. Tesla has framed this as a second line, not the first. The buildout is happening in two phases: a roughly one million unit per year line inside Tesla’s Fremont factory, installed on the floor space vacated when Model S and Model X production ended earlier this year, and a much larger dedicated facility under construction at Giga Texas that broke ground on its first steel structure in May. That Texas facility is the one Elluswamy’s correction refers to, and is expected to reach volume production sometime in 2027.

Tesla Optimus project fires up as Musk sees production line progress
Elluswamy took over Optimus from Milan Kovac last summer and has spent the months since talking up the program’s trajectory. Elon Musk has also floated the ten million figure at Tesla’s 2025 shareholder meeting.
Ending Model S and Model X production to make room for the first Optimus line was one of the more consequential manufacturing decisions in the company’s recent history, retiring two flagship vehicles in favor of a robot that has yet to enter mass production. Musk has previously estimated per unit production costs at $20,000 to $25,000 once Tesla reaches a million units a year, though he hasn’t said what that cost looks like at ten times the volume.
