SpaceX and Tesla CEO Elon Musk stated on Sunday that in-house casting of natural gas turbine blades could accelerate production by up to 18 months. He described the development as a "profound game-changer" for addressing artificial intelligence power needs.

Turbine Production Bottlenecks

Responding to a post by influencer Alexandra Merz, Musk addressed the infrastructure required to support data center power demands. He noted that both SpaceX and Tesla are building 100GW/year of solar production capacity as quickly as possible.

However, Musk acknowledged that natural gas remains necessary to supplement and bootstrap solar energy for several years. He identified casting blades and vanes as the primary limiting factor for natural gas turbine production.

By moving casting operations in-house at SpaceX, the company aims to bring these turbines online significantly faster. Musk characterized this acceleration as critical for bridging the gap between current solar levels and future potential.

Energy Strategy and Market Reaction

Musk also reiterated his view that transitioning to sustainable energy alone may not resolve the climate crisis, mentioning orbital geo-engineering and weather-control satellites as additional measures. He reaffirmed his stance that the economy will increasingly be measured in energy and mass rather than currency.

In related developments, Tesla reportedly discontinued its Solar Roof tiles, pivoting instead to supply conventional solar panels. This marks a shift from its previous building-integrated solar solution.

SpaceX (NASDAQ: SPCX) shares fell 0.73% to $140.46 during overnight trading following the comments.

What the Numbers Show

The disclosure highlights a strategic dependency on manufacturing vertical integration. While the target is 100GW/year of solar capacity, the explicit identification of blade casting as the bottleneck suggests that hardware supply chains, rather than demand or capital allocation, currently constrain the deployment of complementary fossil fuel infrastructure.

Space Exploration Technologies Corp (NASDAQ: SPCX) plans to launch orbital data centers into space as early as next year using its Starship rocket, but experts warn of significant logistical hurdles.

The ambitious project aims to deploy millions of solar-powered satellites equipped with AI chips to create a new orbital data center market. However, achieving this scale requires overcoming three major challenges: launching rockets at unprecedentedly low cost, cooling power-hungry computers in a vacuum, and regularly updating them with the latest chip technology.

Logistical Challenges

Christopher Smith, a senior aerospace engineer at UC Berkeley's Space Sciences Laboratory, highlighted the "tremendous" logistical challenges of maintaining a constellation of 1 million satellites, named Starmind by SpaceX. Smith's calculations suggest that SpaceX would need to launch more than nine Starship rockets daily based on the assumption that the company would replace the data center chips every five years, with each rocket carrying about 60 satellites.

Smith called the plan logistically 'crazy' and costly but cautioned against dismissing it, noting that Elon Musk has repeatedly defied conventional expectations. George Lordos, a space systems architect and lecturer at the Massachusetts Institute of Technology (MIT), believes that an initial constellation of AI satellites could be deployed by 2028. The scale of that constellation, however, remains uncertain. Lordos said SpaceX must significantly reduce Starship's booster and upper-stage turnaround times to rapidly expand its satellite network in the coming years.

Orbital AI Compute Plans

SpaceX is pitching investors on a trillion-dollar vision of millions of solar-powered satellites equipped with AI chips, aiming to create a new orbital data center market and strengthen Musk's position in the AI economy. However, the company acknowledged in its IPO filing that its orbital AI compute plans remain highly speculative, relying on complex, unproven or nonexistent technologies that may never become commercially viable.

Earlier this week, Musk revealed that SpaceXAI, the artificial intelligence arm of SpaceX, was adopting Nvidia Corp.'s (NASDAQ: NVDA) Vera CPUs for a more cost-effective, space-optimized Vera Rubin system for orbital AI. Musk also stated that SpaceX had designed a space-optimized Vera Rubin NVL72 system for launch to orbit in Q4 next year, with significant scale in 2028.

Solar Power and Launch Scale

In May, Musk had anticipated a steady surge in space solar power, with SpaceX's escalating solar power capacity in space. The company's progression from 10 megawatts across 3000 gen1 Starlink satellites to 100 megawatts with 7000 gen2 satellites was noted, with the upcoming gen3 expected to generate 1000 megawatts.

Elon Musk says SpaceX is targeting 30 Starship launches per day by 2030, equivalent to 9,000 launches annually. The ambitious goal reflects SpaceX's push for massive launch scale. However, he acknowledged that the number was "tiny" compared to "airplane flights" per day.

As of July 2026, there have been 13 Starship launches, with 8 successful missions and 5 failures.

What the Numbers Show

The disparity between the current launch cadence and the requirements for the Starmind constellation is stark. With only 13 launches completed as of July 2026, achieving the daily launch rate of nine rockets calculated by Christopher Smith would require an exponential increase in operational capacity. This highlights the gap between current execution and the scale needed for the proposed 1 million satellite network.
