If you aren't familiar with the term Surface Effect, you have probably experienced the sensation on a plane when it is landing. Just before touchdown it suddenly feels like the aircraft just doesn’t want to go lower. It just wants to go on and on due to the air that is trapped between the wing and the runway. This phenomenon or air cushion is called (aerodynamic) “Surface Effect”. Craft in surface effect experience a 250% molecular efficiency increase significantly reducing horsepower/weight ratios by over 75%. The Wright brothers flew in Surface Effect in their early flights close to the ground and benefited from surface effect without even knowing it existed.
This video explains why electric boats must have Surface Effect lift and hydrofoil lift to succeed in attaining today’s complex demands for zero emission propulsion.
