Phys.org- Batteries that "drink" seawater

https://phys.org/news/2017-06-batteries-seawater-power-long-range-underwater.html

"Now MIT spinout Open Water Power (OWP) aims to greatly improve the range of unpiloted underwater vehicles (UUVs), helping them better perform in a range of applications under the sea.

Recently acquired by major tech firm L3 Technologies, OWP has developed a novel aluminum-water power system that's safer and more durable, and that gives UUVs a tenfold increase in range over traditional lithium-ion batteries used for the same applications."

Marina Swap Meet Treasures

Today was the annual Marina Swap Meet - where "treasures of the bilge" may oft' be found - such as this book I picked up for $1 - by the world famous small boat sailor / and master ship wright - that documents the construction of his Lyle Hess designed vessel Taleisin - upon which he and his wife (Lin) circumnavigated. It was serendipitous - for I have met them both - and have sat in the warm cabin of Taleisin on a cold winter day when she was tied to the dock on Lake Union in Seattle for a boat show event.
