The EcoCruiser would be a derivative of the Solar Wingsail Cruiser, differing primarily in that it employs a larger vessel scale and a predominate use of active propulsion in the form of a sophisticated electric drive system and power plant using renewable energy packaged as a fuel such as liquid hydrogen, biofuels like methanol, hydrides, or redox solutions. Depending on type of energy packaging medium, power plants may use either fuel cells or turbogenerators with these possibly being traded-off as the marine settlement evolves its energy production capability. Intended as a ‘fast ship’ with a 40mph cruising speed, the EcoCruiser would rely on marine settlements, remote OTEC power stations, and coastal solar/wind power facilities operated by the communities of TMP as its primary source o
