The '''Sunseeker Duo''' is a twin seat all-electric solar-recharged powered aircraft. Designed by Eric Scott Raymond, the plane can take off and achieve enough height for the motor to be switched off and follow thermals like a glider (sailplane), allowing the batteries to be recharged through the solar cells on the wings.<ref>{{Cite web|title=FLIGHT LOG|url=https://www.solar-flight.com/flight-log/|access-date=2021-04-30|website=Solar Flight|language=en-US}}</ref> Still in testing phase, the company, Solar Flight, does not provide information on the range.
==Development== The Sunseeker Duo is a high aspect ratio side-by-side seat composite construction high-wing aircraft with a T-tail arrangement with a single electric motor mounted in the tailfin (vertical stabilizer) driving a forward mounted propeller. The first all-solar power generated flight was performed near Milan, Italy with company owners Eric Scott Raymond and Irena Raymond. 1510 solar cells capable of generating up to 5 kilowatts power the motor and battery pack.<ref name=IMPAK/><ref>{{cite journal|journal=Sport Aviation|title=Sun Powers First Two-Place Electric Aircraft|page=14|date=July 2014}}</ref> <!-- ==Design== may be combined with above as "Design and development" --> <!-- ==Operational history== --> <!-- ==Variants== --> <!-- ==Units using this aircraft/Operators (choose)== -->
