Flieger magazine reports, “Piper Deutschland AG has announced a strategic investment in MD Aircraft GmbH . The goal of the collaboration is to advance the development and production of the all-electric regional aircraft MDA1 eViator.” (Note: based on later reporting, the power bays may be incorporated into the lower part of the fuselage.  The blog will attempt to gain verification of this.) Signed on September 19, 2025, the agreement “is intended to mark the start of a new chapter in aviation for Piper – with a focus on innovation and environmental sustainabilit,” according to Flieger. Providing MD the financial stability of Piper’s funding and for Piper the planned design for a twin-motored commuter liner in the size and performance range familiar to established Piper customers, the compact should be beneficial to both companies. The MDA1 Aircraft An “all-electric short-haul aircraft with a range of up to 400 kilometers (248 miles),” The MDA1 should suit the needs of most regional commuter lines internationally. We wrote …

Dean Sigler Batteries, Electric Powerplants, Sustainable Aviation Leave a Comment

1Comet, a high-performance, laminar-flow ultralight sailplane, debuted at Electrifly-in 2025 in Bern, Switzerland.  Though looking somewhat like the Ruppert Archeopteryz, there are significant differences. Both 1Comet and Archaeopteryx come in foot-launch and electric-powered versions.  Both fall into the microlight category and are capable of flying in microlift conditions. 1Comet, though, has a broader weight range, from a foot-launched glider with fixed landing gear weighing a total of 165 kilograms (364 pounds) to an electric-powered, retractable gear machine toppin out at 350 kilograms (771 pounds). Archaeopteryx has a removable electric motor behind the pilot, cleverly strapped in with Velcro fasteners.  1Comet has a fixed-position Front Electric Sustainer motor in the nose. The 1Comet web site makes the following claims for the electric-powered version.  “The low weight also makes it the ideal platform for electric flight. With only 30 kg of batteries, you can stay in the air for over 2 hours or climb more than 4000 meters. “The electric glider version …

Jean-Baptiste’s Disruptive Electrifly-in Win

Dean Sigler Batteries, Electric Aircraft Components, Electric Powerplants, Hybrid Aircraft, Solar Power, Sustainable Aviation Leave a Comment

Jean-Baptiste Loiselet is a disruptive force seemingly immune to conventional thinking.  Funding what he calls a “hybrid” aircraft from his life savings, he has flown his solar sailplane around France, set a world altitude record for electric microlight aircraft, demonstrated its airworthiness at the 2024 Paris Air Show, and recently won his third Electrifly-in award at Bern, Switzerland. The term “disruptive” is one of esteem in high-tech America, but translated into French, the hashtag “rupture” leads to Jean-Baptiste’s LinkedIn site or even to his Des Ailes pour la Planète (Wings for the Planet) website.  The following, a translation of the original French, shows how words can be misapprehended. “⚡️ Rupture or not rupture?  (disruption or not disruption?  Your editor’s interpretation.) “🏆 For the third year in a row, I’m at the top of the podium in Electrifly-In Switzerland for the sole reason that I’m the only one in my category: hybrid. “🌱 Hybrid because the Sol.Ex. is a bit of …

Dean Sigler Batteries, Electric Powerplants, Sustainable Aviation Leave a Comment

H55, the Swiss electric light aircraft spin-off of the Solar Impulse Foundation under Andre’ Borschberg’s leadership, has toured America from sunny Florida to sunny California and back to New York’s Hamptons. H55’s Tour of America While Beta’s Alia is making the Grand Tour of Europe, the H55-powered Bristel B25 Energic has made its own Grand Tour of the New World. Completing a “landmark tour” of America, H55’s Bristell B23 Energic went literally from sea to shining sea, visited eight states, and proved its Electric Propulsion System (EPS) to be reliable and trouble-free.  According to H55, the small craft “completed 192 all-electric passenger flights, and [visited] 25 airports across Florida, Alabama, Arizona, Nevada, California, Colorado, Wisconsin, and New York. In Florida alone, the little Energic managed 14 Airport-to-airport flights, 36 demonstration flights, and 12 Static events.  H55 hosted 30 Certified Flight Instructors (CFI and CFII), aeronautical and aviation professors at Embry-Riddle Aeronautical University, Liberty University, and Florida Institute of Technology, two aerospace …

Solarstratos’ New Altitude Record

Dean Sigler Announcements, Batteries, Electric Powerplants, Solar Power, Sustainable Aviation Leave a Comment

Raphael Domjan’s SolarStratos set a new world altitude record for solar-powered aircraft, 9,521 meters, or 31,237 feet, on August 12, 2025. That CBS News and other press outlets saw fit to cover the event is a significant change in coverage from just having the normal technical details explained in the aviation press. The network explained, “The SolarStratos plane made the landmark flight from Sion airport in southwest Switzerland on Tuesday, taking advantage of warm air thermals to go beyond the record that has stood for 15 years.  (That record was held by Andre’ Borschberg in the Solar Impulse.) “The certified altitude record for a solar plane stands at 9,235 meters, or 30,298 feet. “The achievement is ‘one of those unforgettable peaks that define great human and technological adventures,’ the SolarStratos mission said in a statement.” CBS noted the moment when Solarstratos crossed paths with a commercial airliner, “a powerful symbol of what the decarbonized aviation of tomorrow might look like.” …

Getting Battery Materials Without China or Child Labor

Imagine finding essential battery materials in a common mineral and reducing atmospheric CO2 as a side benefit.  Imagine finding a source of these necessary materials without the need to negotiate with China or enrich those who employ child labor for their wealth.  Good News Network (not as Pollyanish as it may sound) featured a picture of a young woman working in a laboratory and the headline, “Chemical Process Produces Critical Battery Metals From This Unloved Mineral With No Waste.” Often, material other than the sought-for material is the largest amount of stuff removed from a mine.  Its worth is usually low because the labor and time involved in extracting any usable minerals is too great for the profits that might be realized.  This seems to be changing with a New Zealand firm called Aspiring Materials. Good News took its lead from the Institute of Electrical and Electronics Engineers (IEEE), which featured Aspiring Materials in its journal, IEEE Spectrum.   That journal …

The Pivotal Helix eVTOL (electric Vertical Take Off and Landing) Aircraft “Gains Warm Response from California Fire Agencies in Multi-Agency Demonstration Series.”  That’s the headline for a Pivotal press release on its recent demonstration for three southern California fire departments.  Seeming to be almost a response to Dr. Brien Seeley’s recent front-page opinion section editorial in the San Francisco Chronicle, Pivotal’s live show helped emergency responders see how rapid aerial response could aid their missions.   Dropping in on stations at the San Bernardino County Fire Department, Southern Marin Fire District (SMFD), and Cosumnes Fire Department, Pivotal personnel gave flight demonstrations and let firefighters try their hand at simulator flying. As Pivotal’s press release notes, “Each demo showcased the potential of Pivotal’s single-seat aircraft to dramatically improve emergency response capabilities, especially in locations where time, terrain and traffic can mean the difference between life and death.” Ken Karklin, CEO of Pivotal, added, “Our aircraft offers a cost-effective, rapidly deployable solution …

Toyota – Solid State or Aluminum?

Dean Sigler Announcements, Batteries, Electric Powerplants, Fuel Cells, hydrogen, Hydrogen Fuel, Sustainable Aviation Leave a Comment

Toyota has been coy with the idea of battery-powered cars, avoiding discussion of their presence in the world for several years, and now springing dual surprises in solid-state and aluminum cells. For several years, Toyota had been promoting a hydrogen fuel system, even developing a hydrogen-based trucking program from its San Diego docks.  and at an Ontario, California location.  They’ve been campaigning a sub-compact Yaris sedan which burns H2 directly, rather than using a fuel-cell electric approach.  Those efforts seem ongoing, perhaps camouflaging their very real battery efforts, which must have been underway for at least a few years.  Proof of that, Toyota has over 8,000 patents for solid-state energy storage. Toyota has been working, “With Japanese petroleum company Idemitsu Kosan to mass produce solid-state batteries. The collaboration will focus on sulfide solid electrolytes, a promising material for EV batteries.”  This partnership has been ongoing since 2013. The chart below, though, shows a renewed and current (no pun intended) interest …

ZeroAvia recently presented at the Paris Air Show and is working intensively on certifying its motors and systems in the United Kingdom.   Their two motors are now joined by several components, including a liquid hydrogen fuel management system.  This system comprises a “lightweight metallic tank design and associated systems for filling, storing, and distributing the fuel as hydrogen-electric technology is increasingly applied to larger aircraft,” according to the company. Here, Val Miftkhov explains the workings of the company at this year’s Paris Air Show.  Of special interest, he compares the positives and negatives of sustainable aviation fuel (SAF) with those of hydrogen fuel cells, a matter of competitive importance. The Motors ZeroAvia has a pair of motors in the 600 kilowatt (804 horsepower) and 2,000 kilowatt (2,680 hp.) range, the ZA600 nearing certification in the UK and the ZA2000 attracting buyers in the regional airliner world.  The company claims several advantages for its motors.  They include, “90% Lower life cycle …

Regent Viceroy Seaglider: Foiling Above the Waves

Dean Sigler Announcements, Electric Powerplants, Hybrid Aircraft, Sky Taxis, Sustainable Aviation Leave a Comment

The Regent Viceroy Seaglider completed its first lift-off on its hydrofoil lifting surfaces, gliding as its name suggests above the (placid) waves of Kingston, Rhode Island.  Of course, that lift is helped by the 65-foot wing, making this a commercially feasible WIG (Wing In Ground Effect) machine.  We have reported on earlier versions of the machine three years ago and late last year.  The configuration has changed from eight motors to twelve, but the overal concept has remeained the same. This configuration has many advantages.  The hydrofoils elevate the craft out of the water and lessen any hull drag on it significantly, enabling it to glide above, rather than plough through the water.  Operatoing in three different modes, the craft can go from navigating crowded harbors to skimming oceans along seacoasts. Simplicity of Operation In full flight mode, the wing operates in ground effect, a cushion of air roughly equivalent to the craft’s 65-foot span.  Flying at this altitude enables …
