We explore the wildest research coming out of world-leading labs and the founders bold enough to try to scale it in the real world. From professors tackling the toughest climate questions to student builders wrestling with the hardest implementation challenges, we tell the unfiltered stories of ideas still in the oven.
Pulling drinking water from desert air — and the Berkeley lab scaling it
Two-thirds of the global population will face water stress by 2050. The answer might be in the air itself. Metal-organic frameworks, invented by Prof. Omar Yaghi, can pull water from desert air at humidity as low as 7%, using only sunlight as an energy source.
The proof of concept works. It worked in Death Valley. The question is whether it can scale to the billions who need it — and at what cost. That gap between the lab and the real world is exactly what this episode is about.
About a third of American households lack access to home EV charging. The transition stalls without curbside infrastructure — but trenching sidewalks to install chargers costs tens of thousands and years of permitting. Voltpost's answer: millions of streetlights already wired to the grid. Scott Fisher has spent 15+ years building the EV charging industry and teaching the economics of sustainable transport at Columbia. Together they'll map the gap between the vision and what cities can actually deploy.
