1. A marine current turbine system for converting current flow into electricity comprising:
a floating spar platform comprising a nacelle at a bottom end, a faired spar at a midsection, and a deckhouse at a top end, wherein the faired spar comprises a teardrop body and a V-shaped tail;
means for mooring the floating spar platform to a bottom of a marine environment comprising a first mooring line coupled to the nacelle and a second mooring line coupled to the deckhouse, wherein the first mooring line and the second mooring line are disposed within a vertical plane; and
a rotor disposed at a downstream end of the nacelle, wherein the deckhouse is configured to provide buoyancy and is at least partially submerged during operation of the rotor to convert current flow into electricity.
