But they do have a flying scale model. Maybe they know what their doing? Productizing it is an whole another matter. |
- i haven´t noteced this. kinda hard to read comments carefully at 2 o clock in the morning.
I too wish it became a true, But Mollers Skycar, Aptera, Elio, Nikola Motors....
Both Coanda and Bernoulli were tested for transportation (either rotary wings, or rotary sails, or to improve STOL performace) and usually utilized only in special (military) applications, where efficiency is not the main concern.
I Will watch their progress though. You found interesting project.
