XPrize, a nonprofit organization that designs and hosts public competitions aimed at benefiting humanity through innovation, will manage the $100 million incentive from Elon Musk’s gigaton carbon removal competition. Musk announced that he would be donating $100M, which was funded by the Musk Foundation, as a prize for the best carbon capture technology last month.
XPrize shared details about the 4-year global carbon removal competition dedicated to fighting climate change and rebalancing Earth’s C02 cycle. Elon Musk and the Musk Foundation’s donation will be distributed in several ways.
First, $1 million will be given to 15 teams with the best CO2 removal solutions. Teams and innovators from around the world are invited to demonstrate their Carbon Removal solutions with a validated scale model to competition judges.
Teams can register to enter the competition and learn more about its guidelines on Earth Day, April 22 2021. The basic criteria for the competition are listed below.
- A working carbon removal prototype that can be rigorously validated and capable of removing at least 1 ton per day.
- The team’s ability to demonstrate to the judges that their solution can economically scale to the gigaton level.
- The main metric for this competition is fully considered cost per ton, inclusive of whatever considerations are necessary for environmental benefit, permanence, any value-added products; and
- The final criteria is the length of time that the removed carbon is locked up for. A minimum goal of 100 years is desired.
Besides the $1 million each of the 15 top teams will received, XPrize will also award a total of 25 student scholarships worth $200,000 to student teams in the competition.
The remaining $100M donation will be allocated prize money given to the winners of the competition, with the first place receiving a grand prize of $50 million, the second place receiving a price of $20 million, and the third place receiving $10 million.

Elon Musk teases Tesla Optimus Gen 3 capabilities: ‘So many improvements’
If you thought Optimus Gen 2 was impressive, Tesla might have a surprise for you.

Elon Musk has teased that huge improvements are coming to Tesla’s Optimus humanoid robot, which is arguably the product that the company is developing with the most potential for everyday use by consumers and valuation increases from a financial perspective.
Optimus is still in the development stages, but Tesla has made great strides in its development over the past several years. It started as a simple idea that was unveiled with a human being in a spandex suit.
Tesla posts Optimus’ most impressive video demonstration yet
Just a few years later, Tesla has developed several humanoid robot prototypes that have made their way to influencers and have lent a helping hand around the company’s manufacturing facilities.
Tesla has already introduced two generations of Optimus, as the most recent release featured a vast number of improvements from the initial version.
The following is a list of things Tesla improved upon with Optimus Gen 2 compared to Gen 1:
- Tesla introduced a weight reduction of roughly 22 pounds, improving efficiency and agility
- Optimus Gen 2 had a walking speed that improved by 30 percent over Gen 1
- Tesla developed more capable hands that had 22 degrees of freedom, double that of Gen 1. This improved object handling
- Optimus Gen 2 had a 2-degree-of-freedom neck, as Gen 1’s was fixed
- Tesla integrated actuators and sensors for better performance. This includes things like foot force/torque sensing, articulated toe sections that are close to human foot geometry for better balance and movement
- Optimus Gen 2 has 28 degrees of overall freedom, improving flexibility from the first generation
- Tesla’s Optimus Gen 2 can do more than Gen 1, and has shown improved motor control and precision, doing things like squats, yoga poses, dancing, and even poaching an egg
These changes essentially brought Tesla closer to what will be the Optimus version that makes it to production. The company has plans to start production for the public in 2026, but some units will be manufactured for internal use within its factories as soon as this year. Tesla has said it could scale to 100,000 units or more by next year.
Musk also revealed to Teslarati recently that the company is in the process of building the production line that will bring manufacturing rates of Optimus to that level.
However, there is another design of Optimus coming, and Musk says it will feature “so many improvements”:

Tesla has said that Optimus will have the capability to perform tedious and time-consuming tasks like folding laundry, babysitting, cooking, walking the dog, and plenty of other things. However, it will be super impressive to see it do things that require true coordination, like threading a needle, for example.
Musk did not hint toward any specific developments that Tesla will aim for with Optimus Gen 3, but the sky is the limit, especially as it will be performing some manufacturing tasks across its factories.

Elon Musk slams Bloomberg’s shocking xAI cash burn claims
Musk stated that “Bloomberg is talking nonsense.”

Elon Musk has forcefully rejected Bloomberg News’ claims that his artificial intelligence startup, xAI, is hemorrhaging $1 billion monthly.
In a post on X, Musk stated that “Bloomberg is talking nonsense.” He also acknowledged an X user’s comment that people “really have no idea what’s at stake” with AI.
Bloomberg‘s Allegations and Musk’s Rebuttal
The Bloomberg News report painted a dire picture of xAI’s finances. Citing people reportedly familiar with the matter, the news outlet claimed that xAI burns $1 billion a month as costs for building advanced AI models outpaced the company’s limited revenues.
Bloomberg alleged that xAI is planning to spend over half of a proposed $9.3 billion fundraising haul in three months, with a projected $13 billion loss in 2025. The report also claimed that of the $14 billion that xAI has raised since 2023, only $4 billion remained by Q1 2025. Even this amount, the news outlet alleged, will be nearly depleted in Q2.
xAI did not comment on Bloomberg‘s claims, though Elon Musk shared his thoughts on the matter on social media platform X. In response to an X user who quoted the publication’s article, Musk noted that “Bloomberg is talking nonsense.” Musk, however, did not provide further details as to why the publication’s report was fallacious.
xAI’s Bright Horizon
Despite Bloomberg‘s claims, even the publication noted that xAI’s prospects are promising. The company, now merged with X, aims to leverage the platform’s vast data archives for model training, which could reduce costs compared to rivals like OpenAI. Tapping into X also allows xAI to access real-time information from users across the globe.
xAI’s valuation reportedly soared to $80 billion by Q1 2025, up from $51 billion in 2024. The AI startup has attracted heavyweight investors such as Andreessen Horowitz, Sequoia Capital, and VY Capital so far, and optimistic projections point to profitability possibly being attained by 2027. This would be quite a feat for xAI as OpenAI, the AI startup’s biggest rival, is still looking at 2029 as the year it could become cash flow positive.

xAI supercomputer faces lawsuit over air pollution concerns
NAACP & environmental groups are suing Elon Musk’s xAI over turbine emissions at its Colossus supercomputer site.

The xAI supercomputer, Colossus, faces a potential lawsuit from the NAACP and the Southern Environmental Law Center over pollution concerns tied to its gas-powered turbines. The facility has sparked debate over its environmental impact versus economic benefits.
The xAI data center has been operational since last year. The company used pollution-emitting turbines without an air permit, citing a 364-day exemption. Southern Environmental Law Center attorney Patrick Anderson disputed xAI’s exemption, stating: “there is no such exemption for turbines — and that regardless, it has now been more than 364 days.”
The groups issued a 60-day notice of intent to sue under the Clean Air Act, challenging xAI’s permit application under review by the Shelby County Health Department.
According to AP, critics argue the turbines emit smog, carbon dioxide, nitrogen oxides, and formaldehyde, worsening health risks in an area with cancer rates four times the national average.
“The permit itself says emissions from the site ‘will be an area source for hazardous air pollutants,’” the Southern Environmental Law Center noted, alleging Clean Air Act violations.
Opponents claim xAI installed up to 35 turbines—exceeding the 15 requested—without community oversight, straining Memphis’s power grid.
xAI responded: “The temporary power generation units are operating in compliance with all applicable laws.”
The company highlighted its economic contributions, including billions in investments, millions in taxes, and hundreds of jobs. At an April community meeting, xAI’s Brent Mayo underscored that the “tax revenue will support vital programs like public safety, health, human services, education, firefighters, police, parks, and so much more.” He projected that xAI would generate over $100 million in tax revenue by next year. The company is also investing $35 million in a power substation and $80 million in a water recycling plant.
Additionally, xAI is transitioning to sustainable power, particularly Tesla Megapacks. It is actively working on demobilizing the gas turbines.
“The temporary natural gas turbines that were being used to power the [xAI’s] Phase I GPUs prior to grid connection are now being demobilized and will be removed from the site over the next two months,” shared the Greater Memphis Chamber. xAI brought Tesla Megapack batteries and a 150-megawatt substation online earlier this year.
Despite xAI’s expansion to a second 1-million-square-foot site, the lawsuit threat underscores tensions between innovation and environmental justice.
