Slocum

Slocum
 n.โ€” ยซSea gliders were conceived in the 1980s by Douglas Webb, a former researcher at the Woods Hole Oceanographic Institution. Only in recent years, though, have they become fully operational and more capable. Some are called โ€œSlocums,” after Joshua Slocum, who in 1898 was the first person to sail single-handedly around the world.…It is a Slocum that has been modified to harvest the energy that it needs to operate its buoyancy-propulsion system from the sea itself. In theory, this sea glider could travel for thousands of kilometres on voyages that could last for years.ยป โ€”โ€œRun silent, run green” Economist (United Kingdom) Feb. 28, 2008.
