Flow Hive. Collect the honey, don’t disturb the bees. Currently Flow Hive is fundraising for production on IndieGoGo, and with a slew of top-level endorsements.
There are a lot of hives in the world now, so there’s a big market if the Flow Hive can be proven to work efficiently at scale. Even if it doesn’t scale to the industrial level of bee farming, I guess it could prove useful for the West’s artisanal beekeepers.
