Tesla’s success ushers in a new era of electric flight

Published

on

Electric flight may not be as far away as we once thought. In the next decade, aircraft are set to see dramatic changes as companies both large and small work to bring fully electric and hybrid flight to market. Airlines, manufacturers, and startups all seem to be moving towards this goal (see below). The race is clearly on and it will change the way we think about flight.

Yet as it was for the introduction of electric vehicles, the first aircraft is short range and seat just a few passengers. Their applications today are limited but to think the industry will stay in this nascent stage would be a mistake. Successes in these small and short-range aircraft will translate forward into larger and longer-range aircraft. The companies that find success here will emerge as leaders in a new era of electric flight.

On the Market Today:

First, it’s important to appreciate that only recently have small electric powered aircraft gone from concepts to commercial use.

Pipistrel’s Alpha Electro is one of these all-electric aircraft. It’s meant primarily for pilot training and just received its airworthiness certification from the FAA in April 2018, becoming the first in the USA to do so. The Alpha Electro only seats two people and is good for an hour of flight plus reserves. That might not sound like much but it could be disruptive. Pipistrel says the aircraft cuts beginner pilot training costs by as much as 70% while producing zero emissions and low noise.

In China, the Ruixiang RX1E is a similar style trainer sold there commercially. They also have a new, longer-range model that was recently tested, the RX1E-A. With a two-hour flight time the new version doubles its previous capabilities. At this size of aircraft the technology is getting close to parity with comparable gasoline-powered aircraft, like the Cessna 162 which has a flight time of about three hours.

Full parity might be here sooner than you think. Coming small electric aircraft have better specs and more seating, with many nearly ready for certification (pictured below). Pipistrel has their Panthera (top right), which will hold four passengers and will come in options for combustion, hybrid, and all-electric powertrains. There’s also BYE Aerospace in Colorado, which has a four-seater in development and just completed the first test flight of the two-seater Sun Flyer 2 — it has a flight time of 3 hours. Ruixiang also announced they have a 4-seater aircraft in development. The other important consideration is that their initial costs appear to be comparable to combustion options as well.

Looking at these options, some will say that an electric aircraft is an isolated niche and for now, that’s mostly correct. These are small aircraft with limited applications. Yet when the Nissan Leaf and even the Tesla Roaster first came out many believed electric cars were a niche technology too. The range was too short, seating was too small, and costs were too high to realistically consider the technology going mainstream. Now we are in the midst of a market transformation, with automakers pouring billions into their EV programs and countries announcing they are phasing out combustion vehicles.

Market Transformation – Near-Term Preproduction:

The next major step for electric flight appears to be in small commuter aircraft. Aircraft that weigh less than 12,500 lbs, carry 5 to 20 passengers and travel up to 750 miles. In addition to regional commuter needs, they may also serve recreational and business purposes. If small aircraft are like the Tesla Roadster then these are like the Model S. They have more seats, longer range, and are made in higher volumes.

The use case of short range regional commuters is almost perfect for electrification. Much of their flight is spent just getting up to altitude, where cruising achieves the greatest efficiency. The time spent cruising however is relatively short and the result is that such regional flights are inherently less efficient than those over greater distances. On the plus side the high operating costs are a great opportunity for electrification. Consider that a turbine engine achieves an efficiency of around 55% at cruising, but on ascent that efficiency can drop by half (~25%). By comparison, an electric motor has efficiencies greater than 95%.

One of the companies working to electrify these regional aircraft is Wright Electric, based out of Los Angeles. They recently announced plans to bring to market a 9-seat electrified aircraft with a range of at least 340 miles. According to their website that would cover the distance of nearly 44% of all flights. The announcement is part of their new partnership with JetEx, a fixed-base operator based in Saudi Arabia with operations in over 30 countries. I recently spoke with Wright Electric’s CEO Jeff Engler about their coming aircraft and where he see’s the industry going. The first thing that surprised me is that their aircraft could be on the market very soon.

“We are certain that the first flight test will take place next year. It could be on the market in just over two years.” – Jeff Engler, CEO of Wright Electric

That means that sometime towards the end of 2020 or beginning of 2021 they could be in their air, operating with paying customers.

Their aircraft is intended for intercity travel and recreational activities Jeff said, but it’s not the end goal. In fact, their approach may be familiar to fans of electric cars.

“Our plan is similar to the Tesla approach, in the sense that they started with the Roadster and then scaled up to larger more mass market vehicles.  Our first plane to market will be a premium aircraft meant to travel short distances with a small number of passengers… perfect for intercity flights and recreational activities like skydiving. This initial program is the springboard for development of larger longer-range aircraft”. – Jeff Engler, CEO of Wright Electric

In regards to the technology Jeff said they are developing the hybrid and all electric powertrains concurrently. He noted that battery advancements will dictate the transition to fully electric flight but in the interim, hybrid solutions will significantly reduce fuel costs, noise, and pollution. With restrained enthusiasm, he was cautiously optimistic about the coming advances in battery technology. Yet battery technology isn’t holding them up.

The beauty of hybrid options is that as batteries improve they can be seamlessly integrated into the design, allowing more of the flight to be electric. For their electric hybrid, Wright Electric likes to use the term “helper motor”. A helper motor can run hard during takeoff and ascent to help bring the aircraft up to altitude, thereby reducing the burden on the combustion engines, improving overall efficiency, and reducing fuel consumption. Once at altitude, the combustion engines can take over, where they operate most efficiently.

Even without being fully electric hybrid aircraft would have surprising benefits to fuel economy, pollution, and noise. Wright Electric has estimated the potential for reducing fuel use by nearly 2/3’s, while fellow electric aircraft startup Zunum Aero indicated 40% to 80% operating savings. Zunum Aero also noted a potential 70% reduction in community noise.

 

More Regional Commuter Aircraft are Coming Too:

Wright electric isn’t the only one working in this space. Other startups are also pushing the industry forward and they’ve partnered with established manufacturers and airlines to help make it happen. It’s similar to the approach Tesla took early on by partnering with established companies like Daimler and Toyota, and even in their recent developments of the Semi.

Zunum Aero is another one of the leaders in the electric aircraft space, based out of the west coast near Seattle. They are developing a 12-seat hybrid-electric, with a targeted range of over 700 miles. First test flights are targeted for 2019 and commercial operation is planned for 2022 (pictured below). Their partners include Boeing and JetBlue and just last week JetSuite announced they would order up to 100 of Zunum’s hybrid aircraft.

Eviation Aircraft is an Israel based company and has great ambitions for their first aircraft named “Alice”. It will be a 9-seat 650 mile aircraft and most importantly “all-electric”. They are targeting brining it to market by 2021. Is all-electric flight on that scale possible by 2021? They’ve said the aircraft will use a 950 kWh battery and just recently signed Kokam as their battery supplier, so they seem to be serious. I hope they make it happen. Alice is gorgeous.

Other Exciting Developments Coming Soon:

In the heavyweight division Airbus, Siemens, and Rolls-Royce have their own partnership, working together on their E-Fan X after the successful small electric E-Fan program. The E-Fan X will be a hybrid demonstrator aircraft based on the 100-seat BAe146. The first test flight is planned for 2020 and they are looking to bring a similarly sized hybrid aircraft to market sometime around 2030. Originally they were going to bring a small electric trainer based on the E-Fan to market in 2017 or 2018 but said the pace of development has set their ambitions upwards. There’s also Airbus’s subsidiary A3 which is working on a small all-electric vertical takeoff and landing aircraft.

E-Fan X

Vertical takeoff and landing aircraft are extremely interesting. They could be the biggest disrupters of all (covered in more detail in a follow up article, part 2). They too seem to be much closer than people think. For flying short distances they don’t actually need massive advancements in battery technology. Norway’s Avinor, their national aircraft operator, seems to indicate the mid 2020’s for practical operation.

Companies like Uber, Lilium, Kittyhawk, A3, and many more are developing electric aircraft capable of vertical takeoff and landing. They look more like flying cars than airplanes and that seems to be the point. These “air-taxis” are meant for hyper-local travel. Something you would hop onto downtown and take to get to across the city or to another nearby city. Lilium is a relatively new startup, founded in 2015, but has already made significant advancements in the space. They’ve already had their first full-scale test flight which is viewable below. Watching it lift off is almost magical.  They brought on former Ferrari designer Frank Stephenson to head their design program and raised $90M to proceed with further development.

Final Thoughts and Intro to Part 2

For fully electric flight a lot depends on batteries, but the technology is already finding applications in short-range, small aircraft. Increasing larger hybrid aircraft are also set to see their application in the real world in just a few years and will yield substantial benefits of their own. These moves should not be discounted. They are a prelude of what’s to come.

Space finally faced the people living next to its next Terafab mega-project

SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.

Published

By

SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.

The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.

Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry

Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.

SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.

SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.

Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.

SpaceX has solved Starship’s biggest challenge, Elon Musk says

Published

Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.

During the company’s first-ever Earnings Call, the SpaceX CEO stated:

“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”

Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.

The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.

These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.

Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.

Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Elon Musk sheds two new bits of detail on Starship after 13th test launch

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.

Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.

SpaceX is coming for wireless giants with Starlink Mobile

Published

on

elon musk phone

SpaceX COO Gwynne Shotwell outlined ambitious plans for Starlink Mobile during the company’s August 4 Earnings call, signaling a direct challenge to U.S. wireless giants like AT&T, T-Mobile, and Verizon.

Shotwell noted that the three companies generate roughly $600 billion in combined annual revenue. “I anticipate us to be able to acquire quite a few of their customers because I think our service will be better,” she said. “We will eliminate dead zones leveraging the satellites in orbit. It will be better during any natural disaster… I’m quite excited about Starlink Mobile.”

SpaceX intends to combine its satellite constellation with terrestrial infrastructure. The company has acquired about 65 MHz of spectrum from EchoStar and plans to deploy next-generation Starlink Mobile satellites in 2027, with upgraded service targeted for the end of that year.

Shotwell described the enhanced network, leveraging more satellites and spectrum, as potentially “100 times better” than the current direct-to-cell offering, which already supports basic texting and app-based voice/video in coverage gaps through partnerships. She also indicated plans for low-cost cellular base stations that could integrate with existing Starlink dishes, creating a hybrid system for broader capacity in urban, suburban, and rural areas.

For the general public, Starlink Mobile promises significant advantages. Satellite connectivity can fill gaps where traditional cell towers fail, delivering service in remote locations, mountains, or during outages caused by storms, wildfires, or infrastructure damage—conditions in which ground networks often collapse.

Users could enjoy more consistent coverage without relying solely on dense tower builds, potentially at competitive prices as SpaceX scales. The hybrid approach aims to support full mobile services, including higher-speed data, while working with unmodified smartphones over time.

These developments revive long-standing but unfounded rumors of a Musk-developed “Tesla phone.” Speculative claims of a “Pi Phone” or similar device with built-in Starlink connectivity have circulated for years on social media, often featuring fabricated images and details. Elon Musk has repeatedly denied any such plans, stating Tesla has no intention of entering the smartphone market unless forced by extreme circumstances with app stores.

Tesla Phone rumors clarified by CEO Elon Musk

No official product, filings, or development announcements have ever materialized; the rumors remain hoaxes.

The announcement quickly pressured telecom stocks. Shares of AT&T, Verizon, and T-Mobile fell between roughly 2 and 4 percent in after-hours and premarket trading as investors weighed the competitive threat from a hybrid satellite-terrestrial network.

While execution challenges remain—spectrum deployment, infrastructure rollout, and regulatory hurdles—Shotwell’s remarks mark SpaceX’s clearest signal yet of entering the consumer mobile market as a full competitor.
