Blackbird (wind-powered vehicle) - Wikipedia
WebBlackbird is an experimental wind-powered vehicle, built in 2010 to demonstrate that it is possible for such a vehicle to go directly downwind faster than the wind (sometimes abbreviated as DDWFTTW). Blackbird employs a rotor connected to the wheels and does not have a motor, battery or flywheel. [1] .

DDWFTTW - Directly Downwind Faster Than The Wind
WebJan 4, 2009 · The propeller simply takes a little power from the wheels (at low force and high velocity) to push the veicle a bit faster than the wind (at higher force and lower velocity). One of the first steps in understanding is to know we are talking about a propeller not a turbine.
DDWFTTW - Directly Downwind Faster Than The Wind
WebJan 4, 2009 · The DDFTTW cart's propeller does the same job as the windmill boat's propeller, and the cart's wheels to the same job as the boat's wind turbine. Zero velocity relative to the medium that provides your thrust is not an issue. According to you, energy is transferred from the air to the ground.

High-performance sailing - Wikipedia
WebHigh-performance sailing. High-performance sailing is achieved with low forward surface resistance—encountered by catamarans, sailing hydrofoils, iceboats or land sailing craft—as the sailing craft obtains motive power with its sails or aerofoils at speeds that are often faster than the wind on both upwind and downwind points of sail ...
