High-altitude balloons to provide cell and internet coverage over Kenya
Loon, an Alphabet subsidiary that graduated from Google’s X factory, will soon provide cell phone coverage to rural Kenyans using high altitude balloons. Cellular coverage is lacking in areas outside the country’s main city hubs due to the need for telecommunications infrastructure, a problem which is also faced in underserved communities around the world. To tackle the challenge, Loon has developed a system of interconnected balloons carrying telecom equipment which travel along the edge of space, relaying communications data over areas needing coverage. This innovative system has the potential to provide cellular connectivity anywhere it’s needed, particularly in areas outside the reach of traditional systems or experiencing emergency conditions.
In order to provide a useful communications system with balloons, Loon’s team needed to overcome challenges involved with relaying data along moving targets rather than ground stations. The team’s engineers developed solutions, adding a triangular gondola containing specialized gimbals to orient the signals between nearby balloons, so that the telecom network could manage the constantly changing configuration and keep the cell data moving without interruption. It also enables the system to work with very little ground infrastructure. One ground station can relay data across the balloons for over 600 miles, as the company demonstrated in September of last year.
Besides the challenges with relaying data, Loon also had to develop an method for navigating the balloons in order to target coverage areas. For this, the balloons were built as two balloons in one – an outer balloon filled with helium, and an inner balloon filled with air. When the inner balloon expands, it compresses the helium in the outer balloon and thus increases density. The more dense the helium, the lower it flies, and vice versa. By combining this range of motion with surrounding air currents, Loon’s team is able to navigate the balloons as needed. They’ve mastered this task well enough that the balloons for Kenya will be launched from Puerto Rico, traveling across the Atlantic Ocean until they reach their destinations in Africa.
The primary purpose of Loon’s system is to provide a communications network where none exists; however, the technology is able to adapt to situations where existing networks have been significantly damaged, such as in extreme weather events. The company has already been successfully applied in emergency situations. When Hurricane Maria hit Puerto Rico in September 2017, the company partnered with AT&T and T-Mobile to provide emergency connectivity to over 200,000 residents while repairs to their cellular infrastructure were underway. Text messaging and Internet access via LTE-compatible phones were temporarily restored.
The company will spend the first half of 2019 testing and finalizing its Kenyan system before Telkom Kenya, the country’s primary cellular provider, begins using the network for rural customer coverage. Loon has already begun construction of the minimal ground infrastructure needed, the stations in Nairobi and Nakuru being complete as are regulatory approvals. Millions of Kenyans stand to benefit from Loon’s mission and technology, and if successful, it will add to the growing options for connectivity in underserved communities around the world.

Elon Musk’s xAI wins permit for power plant supporting AI data centers
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
Mississippi regulators have approved a permit allowing Elon Musk’s artificial intelligence company xAI to construct a natural gas power plant in Southaven. The facility is expected to support the company’s expanding AI infrastructure tied to its Colossus data center operations near Memphis.
The development was reported by CNBC, citing confirmation from the Mississippi Department of Environmental Quality (MDEQ).
According to the report, regulators “voted to approve the permit” of xAI subsidiary MZX Tech LLC to construct a power plant featuring 41 natural gas-burning turbines “after careful consideration of all public comments and community concerns.”
The Mississippi Department of Environmental Quality stated that the permit followed a regulatory review process that included public comments and community input. Jaricus Whitlock, air division chief for the MDEQ, stated that the project met all applicable environmental standards.
“The proposed PSD permit in front of the board today not only meets all state and federal permitting regulations, but goes above and beyond what is required by law. MDEQ and the EPA agree that not a single person around our facilities will be exposed to unhealthy levels of air pollution,” Whitlock stated.
The planned facility will help provide electricity for xAI’s AI computing infrastructure in the Memphis region.
The Southaven project forms part of xAI’s efforts to scale computing capacity for its artificial intelligence systems.
The company currently operates two major data centers in Memphis, known as Colossus 1 and Colossus 2, which provide computing power for xAI’s Grok AI models. xAI is also planning to build another large data center in Southaven called Macrohardrr, which would be located in a warehouse previously used by GXO Logistics.
Large-scale AI training requires substantial computing power and electricity, prompting technology companies to develop dedicated energy infrastructure for their data centers.
SpaceX President Gwynne Shotwell previously stated that xAI plans to develop 1.2 gigawatts of power capacity for its Memphis-area AI supercomputer site as part of the federal government’s Ratepayer Protection Pledge. The commitment was announced during an event with United States President Donald Trump.
“As part of today’s commitment, we will take extensive additional steps to continue to reduce the costs of electricity for our neighbors. xAI will therefore commit to develop 1.2 GW of power as our supercomputer’s primary power source. That will be for every additional data center as well. We will expand what is already the largest global Megapack power installation in the world,” Shotwell said.
“The installation will provide enough backup power to power the city of Memphis, and more than sufficient energy to power the town of Southaven, Mississippi where the data center resides. We will build new substations and invest in electrical infrastructure to provide stability to the area’s grid.”

Tesla China teases Optimus robot’s human-looking next-gen hands
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
A new teaser shared by Tesla’s China team appears to show a pair of unusually human-like hands for Optimus.
The image was shared by Tesla AI’s account on Weibo and later reposted by Tesla community members on X.
As could be seen in the teaser image, the new version of Optimus’ hands features proportions and finger structures that look strikingly similar to those of a human hand. Their appearance suggests that they might have dexterity approaching that of a human hand.
If the image reflects a new generation of Optimus’ hands, it could indicate Tesla is continuing to refine one of the most critical components of its humanoid robot.
Hands are widely viewed as one of the most difficult engineering challenges in robotics. For Optimus to perform complex real-world work, from manufacturing tasks to household activities, its hands would need to be the best in the industry.
Elon Musk has repeatedly described Optimus as Tesla’s most important long-term product. In posts on social media platform X, Musk has stated that Optimus could eventually become the first real-world Von Neumann machine.
In theory, a Von Neumann machine is a self-replicating system capable of building copies of itself using available materials. The concept was originally proposed by mathematician John von Neumann in the mid-20th century.
“Optimus will be the first Von Neumann machine, capable of building civilization by itself on any viable planet,” Musk wrote in a post on X.
If Optimus is expected to carry out complex work autonomously in the future, high levels of dexterity will likely be essential. This makes the development of advanced robotic hands a key step towards Musk’s long-term expectations for the product.

Tesla Cybercab ramps Robotaxi public street testing as vehicle enters mass production queue
Recent sightings on public roads and growing fleet activity at Giga Texas signal Tesla’s accelerating push toward the Cybercab’s commercial launch.
Tesla Cybercab is being spotted with increasing frequency both on public roads and across the grounds of Gigafactory Texas, suggesting that the company’s road testing and validation program is ramping meaningfully ahead of mass production.
A total of 25 Cybercab units were recently observed across three separate locations at Giga Texas by drone observer Joe Tegtmeyer — with 14 metallic gold units parked in a tight formation outside the factory exit, nine more at the crash testing facility undergoing structural and safety validations, and two additional units at the west end-of-line area for final checks.
The activity on public roads is just as telling. The Cybercab was spotted testing on public roads for the first time last October, near Tesla’s Engineering Headquarters in Los Altos, California, marking a significant development in the vehicle’s progression toward commercial readiness. As expected at that early stage, a safety driver was present in the seat.
Since then, sightings have only become more frequent. Community observers on X have posted fresh footage of Cybercabs navigating public streets in Silicon Valley, with each new clip adding to a growing body of evidence that Tesla’s validation efforts are well underway. The production backdrop supports the momentum. Tesla’s production line at Giga Texas moved into a higher volume early in March, representing what observers are calling the largest single-day grouping of Cybercabs seen to date.
