Silas here! 👋 Before we jump into today’s episode, quick shoutout to Goodwin Law, CSC Leasing, and ErthTech Talent, the backbone behind our CleanTechies Live Podcast at Climate Week. (If you haven’t listened to that yet, check it out first — I’ll be referencing it a lot in this recap.) Quick plug: We also caught a bunch of raw takes from founders and investors between panels and events through candid man on the street interviews you’ll definitely want to see. I’ve finally had some time to process New York Climate Week. This solo episode is part recap, part reflection, but more importantly, it’s my honest take on where we are as a space and why I’m more bullish than ever on clean tech, and here are some of the things that stood out: I’ve never seen founders and investors this locked in. Everyone there was focused, sharp, and hungry. It honestly felt different this year, like the movement finally grew up. Let me walk you through it. Over the past year-ish, people have been asking: “Is the hype gone?” “Will funding drying up?” “Is the climate space cooling off?” What I saw at Climate Week says the exact opposite. Now is the best time to build if you’re a founder. In this episode, I break it down into a few key reasons, but before you dive in, chew on this: “When things get harder, only the best founders stay at the party.” The hype-cycle might be over, but that’s because we’re entering a much more mature version of the movement.

Mining isn't the bottleneck for critical minerals—refining is. Traditional metal refining takes months and relies on toxic chemical processes, driving the supply chain straight to China. In this episode, Nikhil Gupta (Founder & CEO of Determinant Materials) reveals how his team uses advanced fluid dynamics to replace months of acid leaching with microparticle refining in mere minutes, slashing costs by 50% and bringing critical supply chains back home. 🔥 Enjoying Climate Cowboys?

In This Episode, We Cover: The Hidden Bottleneck: Why critical mineral security isn't about mining—it’s about processing. Months to Minutes: How Determinant Materials uses microparticle refining to separate metals at a macro scale. Geopolitics & National Security: China’s tungsten export bans, supply chain dominance, and why U.S. economic sovereignty depends on modular onshore refining. Reindustrializing America: Dropping modular refining units directly onto mine sites and defense primes. Key Episode Quotes: "Typical metal refining breaks materials down to the atom layer... We have a microparticle technology where we’re separating things at a bigger macro scale." "China banned the export of tungsten and the price went 10x overnight. China holds all that market power... To have real sovereignty, we need to have this processing here in the United States."

In this episode of Climate Cowboys, host Silas Mahner sits down with Sampriti Bhattacharyya, founder and CEO of Navier, at their headquarters in Alameda, California. While traditional maritime manufacturing remains antiquated and reliant on brute force, Navier is taking a fundamentally different approach: building all-electric hydrofoiling vessels that literally "fly" above the water—reducing drag by 90% and slashing operational costs by 15x. Sampriti breaks down her journey from MIT roboticist to building a generational American maritime company, her vision for a "generalized marine vessel platform" (the Nvidia chip of the sea), and why she chose conviction over hype when VC investors doubted her timeline. ⚡ SUPPORT THE SHOW & JOIN THE MOVEMENT: Become a Paid Subscriber: Unlock exclusive deep dives, founder insights at Climate Cowboys Substack. ⏱️ TIMESTAMPS: 00:00 – Intro & What is Navier?
