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.

Companies working on 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.

At this point, you may be wondering exactly what are the benefits of electric flight. That’s the focus of the second part of this article, coming out soon. They are substantial and will drive the industry forward with haste.

Tesla called ‘biggest meme stock we’ve ever seen’ by Yale associate dean

Published

Credit: Tesla

Tesla (NASDAQ: TSLA) is being called “the biggest meme stock we’ve ever seen” by Yale School of Management Senior Associate Dean Jeff Sonnenfeld, who made the comments in a recent interview with CNBC.

Sonnenfeld’s comments echo those of many of the company’s skeptics, who argue that its price-to-earnings ratio is far too high when compared to other companies also in the tech industry. Tesla is often compared to companies like Apple, Nvidia, and Microsoft when these types of discussions come up.

Fundamentally, yes, Tesla does trade at a P/E level that is significantly above that of any comparable company.

However, it is worth mentioning that Tesla is not traded like a typical company, either.

Here’s what Sonnenfeld said regarding Tesla:

“This is the biggest meme stock we’ve ever seen. Even at its peak, Amazon was nowhere near this level. The PE on this, well above 200, is just crazy. When you’ve got stocks like Nvidia, the price-earnings ratio is around 25 or 30, and Apple is maybe 35 or 36, Microsoft around the same. I mean, this is way out of line to be at a 220 PE. It’s crazy, and they’ve, I think, put a little too much emphasis on the magic wand of Musk.”

Many analysts have admitted in the past that they believe Tesla is an untraditional stock in the sense that many analysts trade it based on narrative and not fundamentals. Ryan Brinkman of J.P. Morgan once said:

“Tesla shares continue to strike us as having become completely divorced from the fundamentals.”

Dan Nathan, another notorious skeptic of Tesla shares, recently turned bullish on the stock because of “technicals and sentiment.” He said just last week:

“I think from a trading perspective, it looks very interesting.”

Nathan said Tesla shares show signs of strength moving forward, including holding its 200-day moving average and holding against current resistance levels.

Sonnenfeld’s synopsis of Tesla shares points out that there might be “a little too much emphasis on the magic wand of Musk.”

Elon Musk just bought $1 billion in Tesla stock, his biggest purchase ever

This could refer to different things: perhaps his recent $1 billion stock buy, which sent the stock skyrocketing, or the fact that many Tesla investors are fans and owners who do not buy and sell on numbers, but rather on news that Musk might report himself.

Tesla is trading around $423.76 at the time of publication, as of 3:25 p.m. on the East Coast.

Tesla makes big change to Full Self-Driving doghouse that drivers will like

Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.

Tesla is making a big change to its Full Self-Driving doghouse that drivers will like.

The doghouse is a hypothetical term used to describe the penalty period that Tesla applies to drivers who receive too many infractions related to distracted driving.

Previously, Tesla implemented a seven-day ban on the use of Full Self-Driving for those who received five strikes in a vehicle equipped with a cabin camera and three strikes for those without a cabin camera.

It also forgave one strike per week of Full Self-Driving use, provided the driver did not receive any additional strikes during the seven-day period.

Now, it is changing the timeframe of which strikes will be removed, cutting it in half. The strikes will be removed every 3.5 days, as long as no strikes are received during the time period.

The change was found by Not a Tesla App, which noticed the adjustment in the Owner’s Manual for the 2025.32 Software Update.

The system undoubtedly helps improve safety as it helps keep drivers honest. However, there are definitely workarounds, which people are using and promoting for monetary gain, and you can find them on basically any online marketplace, including TikTok shop and Amazon:

People are marketing the product as an FSD cheat device, which the cabin-facing camera will not be able to detect, allowing you to watch something on a phone or look through the windshield at the road.

The safeguards implemented by Tesla are designed to protect drivers from distractions and also protect the company itself from liability. People are still using Full Self-Driving as if it were a fully autonomous product, and it is not.

Tesla even says that the driver must pay attention and be ready to take over in any scenario:

“Yes. Autopilot is a driver assistance system that is intended to be used only with a fully attentive driver. It does not turn a Tesla into a fully autonomous vehicle.

Before enabling Autopilot, you must agree to “keep your hands on the steering wheel at all times” and to always “maintain control and responsibility for your vehicle.” Once engaged, Autopilot will also deliver an escalating series of visual and audio warnings, reminding you to place your hands on the wheel if insufficient torque is applied or your vehicle otherwise detects you may not be attentive enough to the road ahead. If you repeatedly ignore these warnings, you will be locked out from using Autopilot during that trip.

You can override any of Autopilot’s features at any time by steering or applying the accelerator at any time.”

It is good that Tesla is rewarding those who learn from their mistakes with this shorter timeframe to lose the strikes. It won’t be needed forever, though, as eventually, the company will solve autonomy. The question is: when?

Elon Musk teases the capabilities of the Tesla Roadster once again

Published

on

Elon Musk has once again teased the capabilities of the Tesla Roadster, fueling the anticipation that many have for the vehicle, despite it still having no public production or delivery date.

The Roadster is among the most anticipated vehicles in the automotive sector currently, and as Tesla has teased its capabilities, from a lightning-fast 1.1-second 0-60 MPH acceleration to potential hovering with cold-gas thrusters, people are eager to see it.

Although the design seemed to be finalized, there was still more work to be done. Earlier this year, as Tesla was showcasing some of the Roadster’s capabilities to Musk, he stated that it was capable of even more.

This pushed back its production date even further, much to the chagrin of those who have been waiting years for it.

Musk continues to tease us all, and as we sit here waiting hopelessly for it to be revealed, he said today that it is “something special beyond a car.”

Musk’s words were in response to a video posted by Tesla China, showing the Roadster in a new promotional video created by a fan.

The Roadster was planned to be released in 2020, but here we are in 2025, and there is still no sign of the vehicle entering production. However, Tesla did say earlier this year that it would host a demo event for the Roadster, where the company would showcase its capabilities.

Lars Moravy said earlier this year:

“Roadster is definitely in development. We did talk about it last Sunday night. We are gearing up for a super cool demo. It’s going to be mind-blowing; We showed Elon some cool demos last week of the tech we’ve been working on, and he got a little excited.”

Tesla exec gives big update on Roadster, confirming recent rumor

The delays have been attributed to “radically increased design goals” for the vehicle, which have, without a doubt, improved its capabilities, but at the same time, we just want to know if it’s ever going to come.

Tesla can always make it “better,” but at what point do you say, “Okay, it’s time to show this thing off.” They could always build another, even more capable supercar in the next ten years.
