French startup Eenuee is developing the Gen-ee, a fully electric 19-seat regional aircraft designed to use 90% less energy than conventional planes. The design combines a blended-wing body for aerodynamic efficiency, an unpressurized carbon-fiber airframe to cut weight, and electric motors operating at 90% efficiency. The aircraft also features retractable hydrofoils for water takeoffs and landings, targeting routes in Scandinavia, Canada, and Asia where waterways replace runways. Eenuee projects a range of 310 miles and aims for commercial service around 2032, with 50 to 100 aircraft delivered by 2035. The unpressurized cabin limits altitude but reduces structural weight by 40%. The company is currently testing scaled demonstrators and plans to begin certification with European authorities in 2027. While battery energy density remains a challenge, the design focuses on aerodynamic and weight improvements rather than waiting for battery breakthroughs.

Interesting concept but 90% energy savings is a big claim. Most of that comes from the unpressurized cabin and blended wing body. The hydrofoil part seems like a niche add on for specific markets.

The unpressurized cabin is a huge trade off. It cuts weight but limits altitude and passenger comfort. For short regional hops it might work but that range of 500 km seems optimistic with current batteries.

The 40% weight savings from no pressurization is clever but it limits the use case. For remote communities in Canada or Scandinavia this could replace small turboprops. But the 19 seat capacity is small. Not a game changer for aviation emissions overall.

The timeline is ambitious. Certification by 2027 and commercial service in 2032. Even if the tech works, getting through EASA for a novel configuration like blended wing body will take time.

Agreed. The regulatory path for a blended wing body with hydrofoils and no tail is uncharted. Also, the unpressurized cabin means it competes more with turboprops than jets. The efficiency gains need to be real to justify the certification cost.
