Kelp Farming, for the Climate (Part II)
So, what do you do with 579 pounds of seaweed? In our last episode, we ventured into the ocean to learn how seaweed farming can help solve climate change. In part II, we ask: What do we do with all that kelp? Plus our team does some seaweed R&D of its own and discovers...green scones? Calls to action Check out the New York State Assembly Bill A4213 on seaweed cultivation and for residents of New York, check out the petition. Encourage innovation with kelp: Whether you work in fertilizers, plastics, cosmetics, or any industry, you can encourage your company to do R&D with kelp. Maybe it could serve as a substitute for less climate-friendly ingredients and materials. And if you need a middleman to source from, check out The Crop Project, founded by Casey Emmett whom we interviewed this episode. Consider kelp products: If you are interested in making any kelp flour recipes, do a search for online retailers and don’t forget to share what you make!

432- The Batman and the Bridge Builder
Mark Bloschock is an engineer from Texas, and in the late 1970s he got a job with the Texas Department of Transportation renovating the Congress Avenue Bridge. The bridge was a simple concrete arch bridge that spans Lady Bird Lake in downtown Austin. It needed to be rebuilt with more contemporary beams called “box beams.” The box beams sit below the road’s surface, and they needed to be spaced a certain distance apart. Bloschock and the other engineers decided that the gap should be somewhere between ¾ of an inch and an inch and a half, which didn’t seem like a particularly meaningful decision… until the bats moved in. A tale of bats and bridges and how the built environment and the natural environment don’t need to be at odds with one another. The Batman and the Bridge Builder Plus, we talk with Simon Doble, CEO of Solar Buddy. Light access (both day and night) is a basic need many people take for granted. SolarBuddy is an Australian charity uniting a global community with a big dream to gift six million solar lights to children living in energy poverty by 2030, to help them to study after dusk and improve their education outcomes. 99% Invisible’s Impact Design coverage is supported by Autodesk.
