Tesla has officially opened orders for its next-generation Powerwall 3 battery on its website, after the company spent much of last year quietly deploying the new hardware.
You can now order a Powerwall 3 from Tesla directly through its website in the U.S., offering updated specs from the previous generation Powerwall 2. Tesla listed the specs for the updated energy storage hardware on its website in September, and it also caught the attention of CEO Elon Musk, who commented on the generation’s improvements after some Powerwall 3 installations had already been spotted.
At the time of writing, the Powerwall 3 doesn’t appear to be available in other North American markets, Canada and Mexico, nor does it appear to be available in Europe or Asia.
PW3 is optimized for ease of installation & high power, which means that a single Powerwall can serve as an uninterruptible power supply for most homes.
This is a big deal for ensuring that the lights stay on and you can power all your devices in the event of a power outage.

Still, this is the first time that it’s been possible to purchase a Powerwall 3 through the Tesla website, and it appears you can no longer purchase a Powerwall 2. Tesla also made some price cuts to the Powerwall 2 in late September, seemingly indicating that the company was preparing for the product’s official launch.
The major difference from the Powerwall 2 are that the Powerwall 3 includes a built-in solar inverter and system controller, which the previous generation did not. In addition, Tesla says the Powerwall 3 is scalable up to four units, while the Powerwall 2 is scalable up to 10 units, potentially making it a better option for large-scale commercial projects that may or may not also require the built-in solar inverter. Musk also highlighted the peak power capacity of the Powerwall 3 as a major selling point for the new generation energy storage equipment in a recent post.
What matters most about Powerwall 3 is that it can handle peak power of ~30kW, which is enough to handle dryers & air-conditioners.
This means that a single Powerwall is now enough for most homes. https://t.co/UOKkkpVJCT

Users who have Powerwalls often report significant savings on utilities bills and the ability to keep the lights on during outages and other times of peak electricity demand. In some areas, solar and Powerwall owners can also participate in Tesla’s Virtual Power Plant (VPP) pilot programs, which essentially let you create massive, distributed batteries with other Powerwall owners to sell electricity back to the grid during peak-demand periods.
You can see the specs for the Powerwall 3 and last-generation Powerwall 2 below, as can be found on Tesla’s website.

Ark Invest sees potential in xAI as the world adopts more AI models
Ark’s new stake in xAI bets on Musk’s future plans. Will the newly merged companies deliver the next AI breakthrough?

Ark Invest reinvested in X Corp in Q1 2025 through its Ark Venture Fund, which converted into a position in xAI, Elon Musk’s artificial intelligence company.
In March, xAI acquired X, intertwining the two companies’ futures. The stock merger values xAI at $80 billion and X at $33 billion. After xAI acquired X, Elon Musk noted that the combined company would unlock “immense potential.” Ark Invest believes in Musk’s vision for xAI and X Corp.
“…the deal created a new combined entity called XAI Holdings Corp., a strategic union that integrates xAI’s cutting-edge foundational models with X’s massive user base of over 600 million strong to unlock a platform that blends real-time communication with AI-enhanced discovery, truth-seeking, and personalized knowledge delivery.
“We believe this merger will be a significant catalyst for consumer AI adoption and foundational model monetization,” Ark noted.
Musk is reportedly planning a valuation adjustment for xAI. CNBC’s David Faber noted in April that Musk hinted at a new funding round for his artificial intelligence startup during an investor call.
The merger supports Musk’s vision to transform X into an “everything app,” where people can communicate, make monetary transactions, catch up on news, and more. xAI is already working on providing financial services. It recently partnered with TWG Global and Palantir to integrate AI with financial services.
In addition, XAI Holdings also has X Money, a payment system that could rival Venmo, Zelle, and Apple Pay. X Corp. secured a Visa partnership in January and money-transmitter licenses in 42 states, including California, in September 2024.
X Money faces opposition in New York from Manhattan Democrats Assemblymember Micah Lasher and state Sen. Brad Hoylman-Sigal, who sent a letter Monday to the state’s Department of Financial Services, urging rejection of X Corp.’s money-transmitter license. The lawmakers cited Musk’s leadership as a risk to consumer data and financial infrastructure.
Ark’s investment in xAI underscores confidence in its AI-driven future, amplified by the XAI Holdings merger. As xAI leverages X’s platform to scale AI innovation, Ark’s stake positions it to benefit from a transformative shift in consumer AI and fintech, despite ongoing challenges.

Starlink’s Direct to Cell expansion into Peru underscores Entel’s regional ambitions, positioning it as a leader in Latin America’s business connectivity landscape. While details of the Peruvian rollout remain forthcoming, the move aligns with the region’s post-COVID-19 economic recovery. Reliable internet is critical for businesses to adopt cloud-based technologies and access global markets.
Starlink’s growing influence in Latin America highlights its role in transforming connectivity for underserved areas. Entel’s partnership strengthens its portfolio and helps businesses navigate a digital economy. As industries in Chile and Peru leverage Starlink’s capabilities, the collaboration could set a precedent for regional telecom providers, fostering innovation and economic growth across diverse sectors.

Bill Gates estimates DOGE cuts will cost children’s lives, Elon Musk responds
Musk responded with choice words towards Gates.

During a recent interview with the New York Times, Microsoft cofounder Bill Gates shared a lot of criticism towards Tesla CEO Elon Musk and his work with the Trump administration’s Department of Government Efficiency (DOGE). Musk, for his part, responded with choice words towards Gates.
Bill Gates on DOGE
In his NYT interview, Gates lamented the fact that funding has been cut for programs that are supposed to help children abroad. Referencing the DOGE cuts made to the money going to Gaza Province in Mozambique, Gates stated that the people doing the cutting are not the most knowledgeable.
“They cut the money to Gaza Province in Mozambique. That is really for drugs, so mothers don’t give their babies H.I.V. But the people doing the cutting are so geographically illiterate, they think it’s Gaza and condoms. Will they go meet those babies who got H.I.V. because that money was cut? Probably not,” Gates noted, adding that there will be “millions of additional deaths of kids” because of the cuts.
The Microsoft cofounder also admitted that he was surprised at the cuts that the Trump administration has implemented through the guidance of DOGE. As per Gates, he expected U.S.A.I.D. to receive a cut of about 20%, but the administration cut far more. “The reductions to U.S.A.I.D. are stunning. I thought there’d be, like, a 20% cut. Instead, right now, it’s like an 80% cut. And yes, I did not expect that,” he said.
Gates and Musk
Considering the nature of the interview, it was no surprise that Elon Musk himself was brought up as a topic. When the Times noted that Musk was not giving much away to the needs of the world’s poor, Gates stated that the Tesla CEO was ultimately the one who pushed for the cuts on U.S.A.I.D.’s budget. These cuts, Gates argued, effectively involve Musk in the deaths of the world’s poorest children.
“Well, he’s the one who cut the U.S.A.I.D. budget. He put it in the wood chipper, because he didn’t go to a party that weekend… the world’s richest man has been involved in the deaths of the world’s poorest children,” Gates stated. Musk, in response, stated in a post on social media platform X that “Gates is a huge liar.”
Musk and Gates have not really gotten along, thanks in no small part to the Microsoft co-founder putting a $500 million short bet against Tesla. In Walter Isaacson’s Elon Musk biography, Gates stated that he was shocked that Elon Musk was super mean to him after the Tesla CEO found out that he shorted Tesla. “Once he heard I’d shorted the stock, he was super mean to me, but he’s super mean to so many people, so you can’t take it too personally,” Gates noted.
