The Progress Eagle is a gigantic concept airliner by designer Oscar Viñals. It's an amazing air transit behemoth, with solar panels and a giant wind turbine, all for a glorious future that may never come to pass.

By design the Progress Eagle is a plane that couldn't work today. The body relies on stronger, better, and cheaper graphene than currently exists, as well as fuel cells and energy technologies that aren't advanced enough to make the giant plane work yet. But Viñals hopes that materials science will advance enough by the 2030s to realize the vehicle. He also wants the Eagle to havesome kind of futuristic tool for "clearing" the atmosphere--by capturing harmful atmospheric particles like C02. No word on how that device would work, however.
