Mott Green, who emerged from a hermitlike existence in a bamboo hut in the jungle of Grenada to produce a coveted Caribbean delicacy — rich, dark chocolate bars that he exported around the world with the help of sailboats, bicycles and solar-powered refrigeration — died on June 1 in Grenada. He was 47.

He was electrocuted while working on solar-powered machinery for cooling chocolate during overseas transport, said his mother, Dr. Judith Friedman.

Mr. Green was born David Friedman, and grew up on Staten Island. He became Mott over the course of many years of visiting and eventually living in Grenada, where residents had a distinctive way of pronouncing his nickname, Moth. He later took Green as his surname to reflect his environmental interests.

Mr. Green tended to flit about as a child, but with focus: he built go-karts using lawn mower engines; he ran the New York City Marathon when he was 16; he dropped out of the University of Pennsylvania just months before graduation — accepting a degree, he felt, would be capitulating to a corrupt social structure — and he spent much of his 20s squatting with a community of anarchists in abandoned homes in west Philadelphia, where he “rescued” food that restaurants had planned to throw away and distributed it to homeless people.
