Digitization and Smart Water? 💪 Get the Water Market pulse for free. In one hour per week, while you do the dishes! 📈 We talk water investment, water tech, water entrepreneurship and water market with entrepreneurs, thought leaders, book authors, scientists, investment funds, VCs, and C-Level experts from water majors. ➡️ Leverage their insights, advice & experience and ensure to stay on top of best practices 🗓️ Tune in every Wednesday (don't miss out! 😅) 🌐 Find all the detailed episode notes, interviews, infographics, and more at http://dww.show Currently in its 10th Season, the "(don't) Waste Water" podcast has already welcomed around 250 guests from Water Majors (SUEZ, Veolia, Jacobs, Xylem, Kemira, Evoqua, Aquatech, SKion Water...), Scale-Ups (Cambrian Innovation, Epic Cleantec, Gradiant, Liqtech, 374Water, Gingko Bioworks...), Start-Ups (Puraffinity, KETOS, 120Water, ZwitterCo, Membrion, Source...), Universities (Berkeley, the Columbia Water Center), Investment Funds (Sciens Water, Mazarine, Burnt Island Ventures...), Business Accelerators (Imagine H2O, Elemental...), Book Authors (Seth Siegel, David Sedlak, David Lloyd Owen...) or Market Intelligence Companies (BlueTech Research, Global Water Intelligence, World Bank, OECD, Isle Utilities...).

On the "(don't) Waste Water" podcast, I strive to make the Water Industry easy to understand for everyone, starting with water professionals, executives, and investors. Hence, he opens the microphone to seasoned, inspirational water experts to discuss their field of excellence. No one can claim an all-around in-depth understanding of a matter as complex as Water. But piece by piece, you can rebuild the puzzle. With curiosity, patience, and passion, Antoine Walter explores topics such as Advanced Treatment Technologies, Water-Energy Nexus (Hydrogen, Lithium...), PFAS removal, Nature-Based Solutions, Wastewater Reuse, Distributed Water Treatments, Water Finance, and Water Entrepreneurship. I actually firmly believe that regular listeners of the "(don't) Waste Water" podcast may, in the end, claim a "Water MBA!" A particular field of interest is how innovation forms, grows and gets widely adopted in a complex and conservative field like the Water Industry. This may be one of the keys to achieving the United Nations Sustainable Development Goal n°6 - #SDG6. Oh, and in short, about me: I'm a water engineer turned avid student of the water business, market, finance, and tech. I'm married, a happy father of three, and I'm French (nobody's perfect 😅).

This Google Device Could End Water Scarcity Forever (Here's Why It Won't)

7/16/2025

What if Google had the solution to save 1 billion people... and just threw it away? Let's find out! Google spent 4 YEARS secretly developing a device that pulls safe drinking water from thin air using only sunlight. They proved it worked. They proved it could help over 1 BILLION people without clean water. Then they just... quit and open-sourced everything in 2021. 😅 Meanwhile, billionaires like Bill Gates, Jeff Bezos, and Mark Zuckerberg poured millions into competing startups trying to solve the same problem, with no better results. What made Google's own engineers walk away from technology that could change the world? As #TeamWater is about to make its comeback, there's a lot to learn here! 🙌 Supporters 🙌 A big thank you to my partner SimpleLab: https://link.dww.show/simplelab And a great shout-out to Blue Foot Membranes: https://link.dww.show/bluefoot #️⃣ All the Links Mentioned in this Video #️⃣ The Google H2E Collection: https://x.company/collection/h2e/ Google's open-sourced geo layers: https://github.com/AWH-GlobalPotential-X/AWH-Geo?tab=readme-ov-file Google's open-sourced CAD drawings: https://github.com/google/h2e_technical_documentation/tree/main The Google X Team's Nature Article: https://www.nature.com/articles/s41586-021-03900-w.pdf The thermodynamics of Atmospheric Water Generation: https://pmc.ncbi.nlm.nih.gov/articles/PMC10293683/#:~:text=Inserting%20the%20constants%20from%20Appendix,heat%20pumps%20and%20heat%20engines Science's recent article on the topic: https://www.science.org/content/article/devices-pull-water-out-thin-air-poised-take My interview with Colin Goddard: https://smartlink.ausha.co/dont-waste-water/s7e2-expensive-heavy-but-desperately-needed-is-source-the-future-of-drinking-water 👋 SOCIAL MEDIA 👋 LinkedIn: https://www.linkedin.com/in/antoinewalter1/ Subscribe to my newsletter: https://www.linkedin.com/build-relation/newsletter-follow?entityUrn=6884833968848474112 ⏰ TIME CODES ⏰ 00:00 Google's forgotten device 01:01 Clean Water: A Moonshot Challenge? 02:21 Google H2E 04:35 Missing the Target (by 10x) 05:45 Open-Sourcing 07:05 More competition? 08:30 The Main Problem 10:31 Giving Up?

The 3 Simple Numbers That Predict Any Water Stock's Future

6/3/2025

I analyzed 139 publicly traded water companies and discovered a simple formula that predicts their valuations using just three parameters: position on the "boring-to-hype spectrum," percentage of digital revenue, and percentage of recurring revenue. This formula reveals systematic market mispricing that creates 8-25% annual return opportunities by exploiting Wall Street's ignorance of water industry fundamentals. Wanna find out? Listen to this!
