Richard Jenkins (engineer)

Jenkins was born in England to Australian parents. He was raised in Lymington, a small village near Southampton and on his grandfather's farm in Western Australia.[5] He became interested in sailing and engineering at a young age: he was dinghy sailing at age 10, working on the last airworthy Short Sunderland flying boat at age 12, building an International Moth dinghy in his early teens, and doing design work for super maxi yachts while attending college. He first crossed the Atlantic when he was 16.[6] He also helped to sail the Matthew, a replica of John Cabot’s 13th century galleon in which the explorer discovered the island of Newfoundland.[7]

On 26 March 2009, Jenkins broke the world land-speed record for a wind-powered vehicle.[8] He reached 126.1 mph (202.9 km/h) in his land yacht Greenbird on the dry plains of Ivanpah Lake in Nevada. The previous record of 116 mph (187 km/h) was set by American Bob Schumacher in 1999, driving his vehicle the Iron Duck in the same location. "Top speed is actually quite scary. The structure and tyre grip is all at the limit, so keeping it in a straight line under full control takes full concentration," Jenkins told The Guardian.[9]

Greenbird is the fifth iteration of the land yacht that was first known as Windjet. Greenbird is powered by a carbon composite wing that produces thrust similarly to how an airplane wing produces lift.[10]

Jenkins attempted to break the world record for sailing on ice on the frozen Canyon Ferry Reservoir in Montana with a vehicle adapted for ice.[11]

A saildrone is recovered in Dutch Harbor, AK, after the 2019 NOAA Arctic missions.

The innovation that allowed Greenbird to break the land speed record was a unique wing/tail/tab system that produced aerodynamic wing control. A tail mounted midway up the wing allowed for very precise control of the "angle of attack" of the wing to produce maximum power while consuming very little energy. Jenkins adapted that system to an autonomous surface vehicle known as a saildrone and founded a company by the same name.[12] Saildrones are wind powered for forward propulsion and use solar to power onboard sensors and computers[13] used to gather ocean data[5][14]

In 2013, Saildrone 1 (SD 1) became the first unmanned surface vehicle to cross an ocean using only wind power. The saildrone was deployed from San Francisco on October 1 and sailed 2100 nautical miles arriving in Kaneohe, Hawaii, 34 days later.[15]
