PNGinc's Sun Ship project is a solar-powered ship using a new propulsion technology. Our new heat differential turbines are "infinite life" engines that outlast photovoltaic panels, and provide more power than PV's.

New ship designs in this century will require an alternative energy approach to reduce fossil fuel use & to halt the negative effects of global warming. Our heat differential turbines can augment marine diesel engines & drastically reduce pollution while the sun shines. Decking, superstructure & above water surfaces can collect solar heat to power ship functions and augment its propulsion system.

Solar sails may also be used on smaller ships or yachts. Combining wind power & solar energy to propel the vessel is a great solution for wind-less days.
