    Terry Arko: Why the Lincoln Memorial Reflecting Pool Keeps Turning Green

    The Lincoln Memorial Reflecting Pool has been turning green since the 1920s, and the reason is baked into its original design. The pool stretches roughly a third of a mile, sits one and a half to two and a half feet deep, holds about 6.5 million gallons, and was built on Washington D.C. marshland that has been slowly sinking ever since. Ravi Kurani brought in Terry Arko, Product Training and Content Manager at HASA Pool with over 45 years in the industry, to diagnose what is really going on and whether it can actually be fixed. What we cover: Still water is algae's best friend. The pool was intentionally designed to stay still to function as a mirror, which means strong surface circulation, the intervention that would help most, directly conflicts with the pool's purpose.The 1920s design got the basics wrong. Built on unstable marshland with asphalt paving and no meaningful filtration, the ground shifted so badly that engineers later had to drive large timber beams beneath the basin to stop it from sinking. The pool has been leaking roughly 16 million gallons of water per year.Nutrients have gotten worse over a century. Phosphates and nitrates in the Potomac watershed are significantly higher today than in the 1920s, driven by population growth, industrialized agriculture, and runoff, giving algae more fuel than it ever had.Nanobubbles buy time, not a cure. Nanobubble ozone systems stay neutrally buoyant in the water column for days or weeks, and combined with hydrogen peroxide generate hydroxyl radicals that destroy a wide range of contaminants. Terry is skeptical the technology alone can fully solve the problem given the pool's underlying design constraints.Chlorine still has no equal on green algae. After 45 years in the pool industry, Terry has not seen a more effective algaecide than chlorine for green algae. The challenge at the reflecting pool is the cost and logistics of daily liquid chlorine dosing at that scale, plus concerns about chloramine odor in a public monument setting.Offline circulation could be the workaround. Terry's proposed fix is to route water through a high-flow filtration loop located off-site, then reintroduce it gently so the surface stays still, preserving the mirror effect while giving the water the turnover and treatment it needs.Terry Arko is Product Training and Content Manager at HASA Pool, a manufacturer of liquid chlorine, liquid acid, and specialty pool chemicals, with over 45 years of experience across field service, chemical development, and water treatment formulations.

    Why AI Data Centers Have a Water Problem: Stanford's Newsha Ajami

    Every time you ask ChatGPT a question, a data center somewhere uses water to cool its servers. Most people have no idea, and neither do the utilities supplying that water. Newsha Ajami, a hydrologist and founding director of Stanford's Governance for Risk, Resilience, Recovery Program (GR3), has spent years tracing water through the hidden seams of the economy, from the electricity charging your phone to the chips powering the AI boom. The U.S. still has no national water strategy, and emerging technologies are arriving faster than the water systems built to serve them.What we cover:- Water's hidden footprint in nearly every product and service, from gas and lithium extraction to electricity generation to data storage- Why the U.S. has no unified federal water mission, and how the Colorado River makes that problem impossible to ignore- The six-pillar national water strategy framework Ajami co-led through the Aspen Institute's National Water Strategy Initiative, two years in the making- How states are welcoming hyperscale data centers for jobs and tax revenue without tying those decisions to water or energy availability, leaving small utilities unprepared- Why standardized water disclosure and a new utility business model, more like a service plan than a metered drip, could unlock the sector the way transparency unlocked startup financeNewsha Ajami is the founding director of the Governance for Risk, Resilience, Recovery Program (GR3) at Stanford's Doerr School of Sustainability, and a commissioner at the San Francisco Public Utilities Commission. Connect with her on LinkedIn: https://www.linkedin.com/in/newsha-ajami-phd/Book rec: Newsha recommended Cloud Cuckoo Land by Anthony Doerr (2021), a novel weaving three storylines across radically different eras, including one set aboard a generation ship guided by an AI, as a reminder that imagination remains the one thing no system can replicate.Also available on:Website: https://www.liquidassets.cc/

    Robert Strand: How a Film Festival Builds Political Will for Global Water Policy

    A film festival launched because one filmmaker couldn't find a place to submit his short about pharmaceutical pollution in New York City's water supply is now pursuing official UN Water partner status, operating across four continents, and screening PFAS films to law students in Tanzania before they even know they have a PFAS problem. Robert Strand built the World Water Film Festival from a cold email to a UN groundwater research center in Delft into an organization with over 400 film submissions and events in Wellington, Guangzhou, Rotterdam, London, and Buenos Aires. The bet is simple: data and white papers stay in people's heads. Film brings water crises into the body. And once it's personal, people move.What Ravi and Robert cover: • How a cold email to IGRAC, the UN groundwater center in Delft, seeded a partnership that brought Henk Ovink, lead architect of the 2023 UN Water Conference, to deliver opening remarks at the festival's New York launch, and why that single exchange became the organizing model for everything that followed. • Why film accomplishes what white papers cannot: Ovink's framing that film takes data out of the head and brings it to the heart became the festival's informal mission statement, tested across 90 films in five themed screening spaces at Columbia University's climate school. • How the festival's global footprint grew almost entirely through relationship chains, from a water journalist in Tanzania opening East Africa, to Water New Zealand hosting in Wellington, to the Dutch Consulate General requesting an event in Guangzhou, to a World Toilet Day screening at Museo Moderno in Buenos Aires. • Why Robert's team is now working with the Law Society of Tanzania to bring PFAS films to environmental law students, because contamination has already been confirmed in Kenya, Uganda, and Tanzania while legal frameworks to fund remediation barely exist. The film profiles Amara Strande, a Minnesota woman who lobbied the state to ban non-essential PFAS before dying of cancer. Minnesota passed the law three to five weeks after her death. • How Robert got his own blood tested at Quest Diagnostics, found himself in the low-to-intermediate PFAS exposure range despite never living near a Superfund site, and what that reveals about bioaccumulation through drinking water, inhalation, and PFAS-treated athletic wear. • What the gaps in over 400 submissions reveal as a roadmap: water footprints and PFAS in women's personal care products are almost entirely unrepresented on film, and next year's World Water Day theme of gender and water is the opening to fill both. • The story of Green Warriors, a film following activists who bought enough stock in a polluting company to earn a shareholders meeting seat, stood up when the company announced record profits, and demanded cleanup funding on the spot. That shareholder pressure contributed to France banning PFAS.Robert Strand is the Founder and Executive Director of the World Water Film Festival, a nonprofit that curates films exploring humanity's personal, communal, societal, and environmental relationship with water.worldwaterff.org Also available on:Website: https://www.liquidassets.cc/

    Cydian Kauffman: Cold Fusion, Deuterium, and the Future of Water

    One cubic meter of seawater holds enough deuterium to yield energy equivalent to 300 barrels of oil, and cold fusion may be the key to unlocking it. Cydian Kauffman, founder of Pure Water Northwest, traces the full arc from today's fragile water-energy grid to a future where coastal seawater simultaneously powers cities and produces drinking water as a byproduct. Along the way, he gets practical about what is actually in your tap and what you can do about it right now. What we cover: - Power and water are tightly coupled. A grid failure quickly becomes a water crisis, and most people who have spent their lives turning on a faucet have no backup plan. - Deuterium makes seawater a dual resource. At roughly 0.015% concentration, one cubic meter holds energy equivalent to about 300 barrels of oil. Cold fusion, recently achieved in a controlled lab environment, is the mechanism that could unlock power generation and deliver clean drinking water as a byproduct of the same process. - Cold fusion sidesteps the cooling constraint that conventional nuclear reactors face, dramatically reducing the water demand of power generation and opening the door to more distributed energy systems. - Reverse osmosis removes 85 to 99.9% of most contaminants, including microplastics, PFAS forever chemicals, chlorine byproducts, and oxidized arsenic. Units with a reservoir tank are the right call; the first draw from a tankless system is often not fully filtered. - Legal limits are not health limits. The EPA sets both a health limit and a legal limit for drinking water contaminants. For arsenic, the health limit is zero, but some level is legally permitted in tap water across most states. If you don't have a filter, your body is the filter. - Flint, Michigan's water crisis could have been addressed for roughly one million dollars using a government-backed coupon system to source and install 30,000 reverse osmosis units while infrastructure was repaired. The fact that it did not happen that way still puzzles Cydian. Cydian Kauffman is the Founder and CEO of Pure Water Northwest, a water treatment company based in Seattle.

    Plantd's Josh Dorfman: Building Homes From Grass, Not Trees

    Ravi Kurani sits down with Josh Dorfman, CEO and host of Supercool, to trace his journey from sustainable furniture startups to co-founding Plantd, a carbon-negative building materials company using renewable grass to replace plywood in homebuilding. Josh shares how Plantd landed a relationship with D.R. Horton (America's largest homebuilder) for 90,000 homes, why he left the CEO role to launch Supercool—a B2B media platform spotlighting real-world climate solutions—and the innovations he's most excited about, from AI-powered HVAC to recycling rare earth magnets. The conversation explores how two former SpaceX engineers moved to North Carolina to grow miscanthus grass and turned it into structural boards that are stronger than plywood in all directions—yet feel identical in a construction worker's hands. Josh breaks down three macro trends proving the low-carbon economy is scaling, spotlights companies like BrainBox AI (cutting building HVAC costs by 25% and carbon by 40%) and Zum (using AI to cut Oakland's school bus fleet from 140 diesel buses to 72 electric ones), and shares the remarkable story of Aeroseal—a 1990s duct-sealing technology shelved for a decade that became a $400M+ company when the right founder came along. In this episode, we discuss: From Furniture to Carbon-Negative Building Materials: Josh's path from running sustainable furniture companies in Brooklyn to co-founding Plantd with two former SpaceX engineers, a company that replaces plywood with boards made from renewable grass, grown by former tobacco farmers in North Carolina.Making Sustainability a Drop-In Replacement: Plantd's boards are designed to feel identical to traditional plywood for construction workers, same density, same nail behavior, so adoption requires zero behavior change. The result: a partnership with D.R. Horton across 90,000 homes.The Low-Carbon Economy is Scaling: Nearly 2,000 climate tech startups have raised Series B or beyond, the world's largest companies are investing heavily in the clean energy transition, and cities are becoming laboratories for climate innovation.AI as a Climate Solution: From BrainBox AI (cutting building HVAC costs by 25% and carbon by 40%, now acquired by Trane) to Zum (using AI to cut Oakland's school bus fleet from 140 diesel buses to 72 electric ones), Josh highlights how AI is accelerating decarbonization across industries.The Rare Earth Recycling Breakthrough: Cyclic Materials is the only company in the world to crack rare earth magnet recycling, attracting investment from Amazon, Microsoft, BMW, and Jaguar, critical for reducing dependence on China's 90% supply chain control.Timing is Everything: The story of Aeroseal: a duct-sealing technology invented in the 1990s, shelved by Carrier for a decade, then revived by a product manager who turned it into a $400M+ revenue company.Connect with the Guest: Josh DorfmanSupercoolFollow Liquid Assets: Website: https://liquidassets.cc/Full Blog Post & Transcript: https://liquidassets.cc/building-houses-from-grass-and-the-rise-of-climate-tech-media-2Host: Ravi KuraniThis episode is sponsored by Hasa, the leader in water treatment solutions for over 60 years.

    Harvesting Thin Air: The End of "Free" Water in Las Vegas

    Ravi Kurani sits down with Rich Sloan, CEO of WAVR Technologies, to discuss a sobering reality: the era of abundant, subsidized water is officially over. From the "bathtub rings" of Lake Mead to the massive water footprint of the AI revolution, Rich explains why the next decade will be defined by the shift toward high-tech, point-of-use water harvesting. The conversation explores the biomimicry behind Waiver's tech—inspired by the skin of an Australian tree frog—which allows for the passive collection of high-purity water from thin air, even in the most arid climates. Whether it's cooling the data centers that power ChatGPT or providing ultra-pure water for kidney dialysis, Rich and Ravi map out a future where we stop relying on aging pipelines and start manufacturing our most critical resource at the source. The End of Abundance: We have exited the period where fresh water is abundant, free, and pure; it is now a tech-driven numbers game. The AI Thirst: Generating AI images consumes a staggering amount of water—roughly 10,000 Bellagio Lakes worth of evaporative cooling for daily GPU power. Frog-Inspired Tech: How Waiver uses a hypersaline solution and a proprietary membrane to "wick" moisture from the atmosphere. Industrial Point-of-Use: Why the first million dollars in revenue is coming from high-purity industrial needs like medical applications and semiconductor manufacturing. The Warrior's Flow: Rich’s philosophy on staying "fierce" but in a state of "flow" to drive world-class innovation.
