Two-Seat Electric Plane Aims To Break 80,000 Foot Electric Flight Record

July 26th, 2018 by  


Electric high-altitude flying is still something we haven’t written much about. How about 80,000 feet (24,400 kilometers) in the sky. That’s what the electric solar airplane Mission SolarStratos is all about?

First Solar Two-Seater Plane Aims to Break 80,000 ft Record by 2020

Solar flight has already pushed boundaries, with flights around the globe — all the way around the globe. But flying twice as high as the highest commercial jetliner using the sun’s energy is the next frontier. The Mission SolarStratos expedition hopes to meet that target within the next two years.

Mission SolarStratos Specs At A Glance   

The Mission SolarStratos was designed by Calin Gologan of Elektra-Solar GmbH, and is also a technical partner on the project. The e-plane stretches to 8.5 meters, roughly 30 feet, with a wingspan of 24.8 meters, about 81 feet. It weighs 450 kilograms (992 lbs). In order to save on weight, the cabin won’t be pressurized and the pilots will wear pressurized suits using solar energy.

Technically, the electric motor produces up to 32 kW, powering four 2.2 m blades at 2200 rpm, with an efficiency of 90%.

It uses 22 square meters of solar cells to harvest solar energy, each reaching 22% to 24% efficiency and feeding that electricity to a single 20 kWh lithium-ion battery. This gives the Mission SolarStratos an autonomy of more than 24 hours.

According to SolarStratos President and Pilot Raphael Domjan: “SolarStratos has an opportunity to push the limits of what we think is humanly possible and prove that renewable energy has the capacity to power our lives while preserving our planet. We are fortunate to energize SolarStratos with SunPower’s industry-leading solar technology and look forward to further showcasing the value of innovative and reliable solar solutions for the world to see.”

Why Fly So High On Electricity?

This experience pushes the limits of high-altitude electric flying. Sure, there was the Solar Impulse 2 and even PlanetSolar, an impressive solar energy catamaran. Now we are going for the stars, almost.

In the meantime, you can follow the adventure here and elsewhere online on Facebook, Twitter, Vimeo, and YouTube.

About the Author

Nicolas was born and raised around classic cars of the 1920s, but it wasn't until he drove an AC Propulsion eBox and a Tesla Roadster that the light went on. Eager to spread the news of that full torque, he was invited to write for various CleanTech outlets in 2007. Since then, his passion led to cover renewable energy, test drives, podcasts, shoot pictures, and film for various international outlets both in print and online. Nicolas offers an in-depth look at the e-mobility world through interviews and the many contacts he has forged in those industries. He particularly enjoys communicating about the new e-mobility technology and what it means to us as a society. Today he focuses most of his writing effort on CleanTechnica, a global online outlet that covers the world of electric vehicles and renewable energy. His favorite tagline is: "There are more solutions than obstacles."
