"his effort was to make world peace but he got caught up in the Gulf Stream"

The Coast Guard first encountered Baluchi on Wednesday after receiving a report about a man in a bubble off the coast of Miami, disoriented and asking for directions to Bermuda, a Coast Guard press release said. It was not clear when he started his quest.

A Coast Guard cutter found Baluchi. Officials described the craft as a "hydro pod bubble" and a man in a 2013 YouTube video called a Baluchi bubble "a big hamster wheel." It moved along the ground as Baluchi ran inside.

In the press release, the Coast Guard said Baluchi had protein bars, bottled water, a GPS and a satellite phone. The Coast Guard conveyed the voyage's dangers and asked Baluchi to quit his journey because he didn't have enough supplies. But he wouldn't leave his vessel, officials said.
