I was knocking back a Harpoon IPA last week in an old textile warehouse in Boston, thinking about what Massachusetts will mean to the global economy in this century.
The beer had been brewed by a company headquartered just a few blocks away, in the Seaport District. But it had been chilled in a giant steel vat designed by another company, Promethean Power Systems. Promethean is developing technology that uses energy from the sun to operate a refrigerator, intended to help farmers in developing countries keep milk and produce fresh longer, increasing their earnings. The sun-cooled beer was being served at a grand opening party for Greentown Labs, a grungy-but-proud-of-it workspace occupied by Promethean and eight other start-up companies developing new energy-related technologies.
