Back in the early 90s, MIT's Prof. Mark Drela created a motor-less hydrofoil known as the Decavitator. Using nothing but his own leg power to turn the craft's 10-foot (3-m) air propeller, he got it up ...
While teams try to build a car that can go as fast as the speed of sound, other researchers are trying to break a more modest record – can a boat powered by human effort go faster than 20mph? On a ...
The submerged propeller support in the Flying Fish II provided mechanical complexity and increased drag. The Decavitator shown in the photograph and diagram overcomes these problems by using a 3 m air ...
The use of a bicycle power train in conjunction with a large air propeller also became the favored mode of power transfer in the record setting Decavitator hydrofoils. The photograph and diagram show ...
On a cold day in October 1991, a team from the Massachusetts Institute of Technology (MIT) led by physicist Mark Drela set a record for the fastest human-powered water craft. Their hydrofoil, ...
