Yesterday we learned about some agricultural innovations. There’s the nutritious spirulina (aka algae), which is being grown on a Thai rooftop, collected, semi-dried and added to pastas, puddings and more. It tastes like whatever it’s in, but it packs an impressive amount of protein into a tiny package. Maybe it will help feed the world’s burgeoning population in 2050. Or at least that’s the hope of its producer.

Spirulina is much more appetizing than another idea we heard about today: black soldier flies. Though no one was proposing that we start eating them — yet —the critters are being dried and used for fish food. So if you eat the fish … well, you know.

One more drying story is that of Rhino beads, ceramic beads that absorb moisture, keep seeds fresh and reduce spoilage, where farmers lose an impressive percentage of their crops.

As I sat there taking notes, my mind was full to bursting with the possibilities of it all. After the presentations and interviews, I walked down the street to a nearby park, where runners were making the circuit. From mental energy to physical energy.

It was an energetic whirlwind of a day. I want to capture and store it — not unlike seeds or spirulina —and save it for another day.
