Ravi Kurani sits down with Gregory Holliday, Director of the 50 Liter Home Coalition, to explore how global brands and cities are redesigning the way we live — creating homes that use just 50 liters of water a day, yet feel like 500. Gregory unpacks how companies like Procter & Gamble, Kohler, IKEA, and Electrolux are uniting to make sustainability invisible — embedding efficiency into every shower, dishwasher, and faucet without asking people to sacrifice comfort.

He shares the coalition’s origins in the wake of Cape Town’s “Day Zero,” his own journey from U.S. diplomat to water advocate, and how behavior, design, and technology intersect to make conservation intuitive. The conversation dives into the data behind 50L’s pilot homes in Los Angeles, the lessons from real families living efficiently, and the long-term vision for water- and energy-smart homes worldwide.

Ravi Kurani sits down with Ramzi Bouzerda, founder and CEO of Droople, to explore how the Internet of Water is turning everyday plumbing into a data-driven network. Ramzi explains how sensors measuring flow, temperature, and pressure can map “water signatures” for toilets, faucets, and filters, revealing human behavior, maintenance needs, and efficiency opportunities.

He shares Droople’s origin story, born at 3 a.m. while preparing a baby bottle, and his journey from banking and IT to building a company tackling global water scarcity. The conversation dives into how data transforms buildings into living systems, why the water industry is slow but lucrative, and how Droople’s vision could make “water inside” as common as “Intel Inside.”

In this episode of Liquid Assets, host Ravi Kurani dives into a game-changing approach to sustainable desalination with guest Bruce Crawford, CEO and co-founder of Nona Technologies. An MIT spinout backed by the U.S. Army, Nona is pioneering a new way to turn saltwater into fresh water at any scale. At a time when many countries are investing in large-scale desalination megaprojects to combat water scarcity – for example, Saudi Arabia’s ambitious Vision 2030 program – Bruce’s vision is radically different: bring Desal to the people via small, flexible systems that can work anywhere.

From decentralized water treatment units that fit on a pallet to innovations in reusing cooling tower water, Bruce’s story exemplifies how water tech startups are driving the future of water. This conversational yet insightful discussion explores how Nona’s novel Ion Concentration Polarization (ICP) technology makes desalination portable, efficient, and adaptable – unlocking resilient water solutions for a thirsty world.

What you'll hear in this episode:

• A breakthrough in desalination technology: How ICP (Ion Concentration Polarization) works to separate salt from water without high pressure or heat, and why it’s a leap beyond traditional reverse osmosis.
• Decentralizing water treatment: Why moving desalination from massive plants to modular, on-site systems can bring water to remote communities, disaster relief operations, and even military field camps.
• Water reuse in cooling towers: How Nona’s compact desal units can recycle blowdown from industrial cooling towers (like those in data centers and power plants), saving huge volumes of water amid the booming demand for AI and cloud computing.
• Challenges and rewards for water tech startups: Insight into Nona’s journey from an MIT lab project to an award-winning startup, and how it fits into a larger wave of innovation in the water industry.
• The future of sustainable water innovation: Bruce’s vision of a world using less water – from household-sized desalination appliances to industry-scale water savings – and how physical technologies and digital water solutions together can secure our water future.
