Two related items, on an emerging technology–solar powered ships.
First a solar powered vessel completes an around the world journey. It did take them quite a while.
And of more immediate interest, the Marine Log is reporting a builder is offering a solar power augmented alternative to the Fast Response Cutter (FRC).
It takes so little power to move a ship at modest cruise speeds, there might be a place for this in our future. I still wonder about walking around on the solar cells on the proposed FRC alternative.
