Elon Musk, founder of SpaceX and chief executive officer of Tesla Inc., arrives at the Axel Springer Award ceremony in Berlin, Germany, on Tuesday, Dec. 1, 2020.
Tesla CEO Elon Musk said Wednesday that his electric vehicle and solar business could help bitcoin miners switch to renewable energy, but is currently limited by tight supply of battery cells.
He also acknowledged that Tesla is still not manufacturing its custom-designed 4680 cells for commercial use in electric cars or energy storage systems yet.
The comments came during an appearance at The B Word Conference, which was focused on bitcoin and other cryptocurrencies. During a panel, Square Crypto lead Steve Lee asked Musk what the energy-intensive bitcoin industry can do “to accelerate the transition to renewable energy” and “could Tesla Energy play a role?”
Musk replied, “Well, I think Tesla can play a role.”
Then, the 50-year-old CEO broke into a reflective moment, implying that Tesla’s entire reason for existence was to transition the world to clean energy.
“I would say I’ve had some pretty tough life experiences and Tesla’s probably responsible for two-thirds of all personal and professional pain combined to give you a sense of perspective there.”
Tesla’s energy business
Tesla has been selling commercial and residential solar installations since acquiring SolarCity in 2016 for around $2.6 billion, a deal that landed Musk in a Delaware court this month.
But before it got into the solar business, Tesla created and began selling energy storage products in 2015, including a backup battery for homes called the Powerwall, and larger batteries that can store solar or wind energy generated intermittently so it is available for use whenever utilities need it.
Tesla has installed a number of these utility-scale energy storage systems, Musk reminded his audience on Wednesday, that have helped utilities with “load-leveling the grid,” including in South Australia and elsewhere. But he noted that battery production was currently constraining produciton.
“In fact the limiting factor for us right now is cell production. So we need to both internally get our Tesla internal battery cells produced as well as increase supply from suppliers.”
Musk also repeated that even once Tesla can make its own battery cells, it will still rely on other battery cell makers. Its current cell suppliers include Panasonic, LG and CATL.
“Generally when I talk to our suppliers and they say ‘how many cells would you like?’ I say ‘how many cells can you make?’ you know ’cause sometimes they’re concerned, is Tesla gonna compete with them on cells? I’m like no no, if you want to make the cells be our guest. It’s just that we need a crazy number of batteries.”
In a Twitter exchange with fans after the bitcoin conference, Musk wrote that Tesla is still “not quite done” getting to “volume production” of its custom-designed 4680 battery cells.
He also acknowledged that Tesla sold Maxwell Technologies’ ultra-capacitor business and other assets to a San Diego-based startup called UCap Power, which is led by Gordon Schenk, preivously Tesla’s VP of sales for its Maxwell division.
Tesla initially acquired Maxwell in 2019 in a deal valued over $200 million. The exact terms of the sale to UCap Power Inc. were not disclosed, but may be discussed when Tesla holds its second-quarter earnings call on Monday, July 26.
Finally, at The B Word conference, Musk said energy storage systems, combined with solar and wind weren’t the only ways to transition bitcoin to cleaner energy. He endorsed existing hydropower, geothermal and nuclear energy to reduce the environmental impact of bitcoin mining.
“My expectation is not like that the energy production must be pure as the driven snow, but it also cannot be using the world’s dirtiest coal which it was for a moment there. So. You know, that’s just difficult for Tesla to support in that situation. I do think long-term renewable energy will actually be the cheapest form of energy, it just doesn’t happen overnight.”
A new video surfacing from a Tesla demonstration in Miami this weekend shows the Optimus humanoid robot taking a nasty fall. But it’s not the fall itself that is raising eyebrows, it’s the specific hand movements the robot made on its way down, which strongly suggest it was mimicking a remote operator frantically removing a VR headset.
Humanoid robots are all the hype right now. Billions in investments are pouring in, and Elon Musk claims it will be a trillion-dollar product for Tesla, justifying its insane valuation.
The idea has been that with the advent of AI, robots in human form could use the new generalized artificial intelligence to replace humans in an increasingly larger number of tasks.
However, there are still many serious concerns about the effort, both at the ethical and technological levels.

Technologically, most humanoid robot demonstrations have relied on remote control by human operators – pointing to a remaining gap between the software and hardware.
That was more than a year ago, and despite claims that Tesla has made “AI demos” of Optimus since, it appears the company still relies on teleoperation to control them during demonstrations.
The Tesla Optimus Miami Incident
This weekend, Tesla held an event called ‘Autonomy Visualized’ at its store in Miami. The goal was to showcase Tesla’s “Autopilot technology and Optimus.”
However, there was nothing “autonomous” at Tesla’s “autonomy” event.
Many Tesla fans were seen posting videos of a Tesla Optimus robot handing out bottles of water at the event. It was also seen posing for pictures and dancing.
On Reddit, someone posted a different video of the demonstration:
As you can see, Tesla Optimus moved its hands too quickly, causing some water bottles to drop to the ground. It then loses its balance and begins to fall backward.
But the most interesting part is that just before falling backward, both of its hands immediately shoot up to its “face” in a distinct grasping motion, as if pulling an object off its head.
The robot, of course, is not wearing anything on its head.
The motion is instantly recognizable to anyone who has used VR or watched teleoperation setups. It appears the human operator, likely located backstage or in a remote facility, removed their headset in the middle of operating the robot for unknown reasons.
Optimus faithfully replicated the motion of removing a non-existent headset as it crashed to the floor.
Here’s a look at how Tesla trained Pptimus with VR headsets in its lab:
Electrek’s Take
This is embarrassing, but not just because the robot fell. Robots fall; that’s part of the R&D process. Boston Dynamics blooper reels are legendary, and they never really eroded the company’s credibility.
The problem here is the “Wizard of Oz” moment.
The specific motion of removing the “phantom headset” destroys the illusion of autonomy Tesla tries so hard to curate.
Even recently, Musk fought back against the notion that Tesla relies on teleoperation for its Optimus demonstration. He specified that a new demo of Optimus doing kung-fu was “AI, not tele-operated”:
Musk said again during Tesla’s last earnings call in October:
“Optimus was at the Tron premiere doing kung fu, just up in the open, with Jared Leto. Nobody was controlling it. It was just doing kung fu with Jared Leto at the Tron Premier. You can see the videos online. The funny thing is, a lot of people walked past it thinking it was just a person.”
Musk keeps telling shareholders that Optimus will be the biggest product in history and that millions of units will be working in factories soon. But if they are still relying on 1:1 teleoperation to hand out water bottles right now, it feels like we are still far away from a useful generalized Optimus robot.

After images of an the new mid-sized electric crossover were leaked by the Chinese MIIT, Nissan pulled the wraps off its all-new NX8 – and it looks so good, I’m wondering if it couldn’t spearhead the brand’s American turnaround.
Like its sedan siblings, the all-electric version of Nissan NX8 crossover rolls on an 800V system architecture and features a CATL-sourced LFP battery pack with 5C ultra-fast charging technology (xC is how many you can charge in an hour, effectively, so 60 minutes divided by 5 = it can charge in as little as 12 minutes). That battery reportedly sends power to a single electric motor putting out either 215 kW (~290 hp) or 250 kW (~335 hp), depending on model.
EREV version of the NX8, meanwhile, features a similar setup to the N6, pairing a 1.5L ICE producing 109 kW (~145 hp) with a 195 kW (~260 hp) electric motor. Expect the NX8 EREV to get slightly less than the N6’s claimed 112 miles of electric-only range (Chinese cycle).
The NX8 is expected to reach its first customers in April 2026. Take a look at some of the firs official photos of the new Nissan crossover, below, then let us know how you think this would do in the US in the comments section at the bottom of the page.

This week, BYD crossed a major manufacturing milestone as its battery production crossed 113 GWh in the first three quarters of 2025 – but instead of celebrating, the company is doubling down with a new “Zero Defects” initiative to bring battery quality to an even higher level.
CarNewsChina reports that the new “Zero Defects” plan at BYD was launched internally at the start of Q3, with a focus on minimizing manufacturing defects across all stages of the battery’s life, from the manufacturing line to the end user.
The initiative coincides with BYD’s growing role as a battery supplier to other automakers and its expanding battery energy storage system (BESS) business, which are giving BYD both an international footprint and global benchmarks.
In its ongoing bid to prove itself even further in the global battery market, BYD will reportedly emphasize operational efficiency, error reduction, and standardization across manufacturing, process control, and customer service, with the end goal believed to be, “management practices comparable to those of Toyota.”
Note that BYD has not released official details regarding performance metrics or milestones for its new Zero Defects goal, but the message is clear: BYD plans to keep getting better.
