‘Green’ Energy Observer vessel docked in NYC for Earth Day

Before the creation of engines, the ocean was full of low-emission vessels — they were called sailboats.

Now a next-generation zero-emissions laboratory vessel called the Energy Observer recently docked in New York City to show off what this team hopes is the next generation of earth-friendly boats. Elena Wolf has the story, narrated by Anna Rice. Videographer: Max Avloshenko .
