When you think of garage-based tech start-ups, hardware makers like Apple or data-manipulators like Google probably spring to mind before biotech, and way before farming. Lewis Weil, though, has for the last several years been perfecting the art of growing seaweed in central Texas, and his Austin Sea Veggies have garnered interest from gourmets and restaurants across the U.S. In large part, that's because seaweed is so useful for industrial purposes, it's getting harder to find eating seaweed these days. Lewis says there's nothing stopping anyone with an interest in aquaculture in emulating his success as an inland ocean farmer, but has some cautions, too -- when small things go wrong, or a record heatwave overcomes humans' puny air conditioning systems, your seaweed harvest can fail just like any other crop.
