I might love yacht ROCK, but I'm definitely not a yacht guy. This however, is one amazing freaking yacht. Check out the Sinot Aqua. This 367-foot watercraft runs entirely on liquid hydrogen and fuel-cell technology and its only emmission would be water. With a top speed of 17 knots, this baby can accommodate 14 guests and 31 crew members. Throw on some Michael McDonald-era Doobie Brothers and take a tour below.
