“The Revolutionary Boat Powered by the Ocean”
A new design of ship in the Philippines is hoping to pose a low-carbon alternative to the country’s usual bangka [a trimaran with bamboo outriggers either side of its main hull], by working with the power of waves rather than against them. The ship is a hybrid model, using multiple internal combustion engines for initial propulsion but switching to wave energy while cruising in open waters.
. . . . .
The hybrid trimaran has this machinery – a wave energy converter – in the form of hydraulic pumps integrated into its outriggers. As the pumps move through the waves, they harvest the momentum of these waves, converting their kinetic energy into electrical energy, which will then be fed into a generator that will supply electricity to the ship. The electricity then provides propulsion via a motor. The more waves the trimaran encounters, the more power it can produce from those waves.

[T]he team is aiming to finish building the ship by the end of 2020, with a three-month sea trial scheduled for the first quarter of 2021. The vessel is expected to be capable of carrying 100 passengers, four vans and 15 motorcycles.
