Lawrence Allen, founder and CEO of Terranova, explains why flooding and land subsidence are unsolvable with seawalls alone — and how his company is using underground robotics and woodchip injection to physically lift sinking land back up.

We explore the scale of the global subsidence crisis, why cities from Jakarta to Miami to San Francisco are running out of options, and what it would take to deploy this technology at city scale. If you're interested in climate resilience, infrastructure, real estate, defense technology, or the future of human engineering, this episode maps out a solution most people assumed was impossible.

In this episode:

• Why seawalls fail against permanent sea level rise — and the coastal cities most at risk

• How Terranova's robots inject woodchip slurry 60 feet underground to lift an acre of land by a foot in a single day

• Why woodchips are cheaper than dirt and available at massive scale in flood-prone regions

• How AI and machine learning are being used to map underground soil conditions and predict injection outcomes

• The permitting landscape, groundwater safety, and why regulators have been surprisingly supportive

• Terranova's current deployments, customer pipeline, and path to lifting entire cities

• Defense applications: levee reinforcement, military base preservation, and the Army Corps of Engineers

• Why this technology could unlock billions in stranded coastal real estate and solve California's water infrastructure crisis

Ethan Loosbrock, founder and CEO of Oros Energy, explains why batteries are the critical bottleneck holding back electric vehicles, drones, robotics, grid storage, and beyond — and what next-generation battery chemistry could unlock.

We explore the global battery supply chain, China's dominance in production, and what it would take for the U.S. to rebuild domestic leadership in advanced energy storage. If you're interested in EVs, clean energy, energy independence, or the future of transportation and AI infrastructure, this episode maps out what comes next.

In this episode:

• Why battery energy density and cost remain the core constraint across EVs, drones, robotics, and electric aircraft

• How breakthroughs in battery chemistry could open up entirely new applications in defense, aerospace, and autonomous systems

• The current state of the global battery supply chain and why China dominates production

• What the U.S. would need to do to reclaim leadership in advanced energy storage

• How lower-cost, higher-performance batteries could reshape global energy markets and AI infrastructure 🎯 Join the Rational Optimist Society (Free): https://zpr.io/Cm2bNANWYsy4 If you're ready for deeper insights and fresh takes on today's critical issues, hit the subscribe button!

Jamie Metzl explains why he believes "AGI is BS," what artificial intelligence will actually mean for jobs, and how humanity can navigate the biggest technological transition in history.

Jamie is a leading expert on AI, genetics, biotechnology, and the future of humanity. In this conversation we discuss AGI, AI ethics, the future of work, AI education, human-centered technology, and why transparency in AI use matters more than ever.

Jamie and host Stephen McBride discuss: • Artificial general intelligence

• AI jobs and the future of work

• AI ethics and transparency

• AI as a creative partner

• The AI Ten Commandments

• Education in the age of AI

Is the panic over AI justified, or is it just the latest verse in a song we've been singing for centuries?

In this episode, Pessimists Archive founder Louis Anslow argues that the current hysteria isn't about safety - it's about power.

We explore Louis's "Seven Deadly Cynics" framework - identifying the specific groups (from politicians to protectionists) that have historically tried to ban everything from coffee and bicycles to the Walkman. We dive into why the ruling class always fears progress, why the "War of the Worlds" panic was a media hoax, and why understanding this history is the ultimate weapon for Rational Optimists today.

A handful of $500 drones recently caused $5 billion in damage to a fleet of Russian strategic bombers. This is the new reality of warfare, and America is not ready. In this episode, CX2 founder Nathan explains how the cheap drone revolution is forcing the US to completely reinvent its military playbook.

We dive deep into the invisible battlefield of electronic warfare, why our multi-million dollar missiles are now being defeated by simple GPS jammers, the secret strategy of "shooting the archer, not the arrow," and how a new generation of founders is building the decentralized, autonomous systems that will define the future of American power.

China's DJI owns 90% of the US commercial drone market. A nationwide ban is about to make them illegal, threatening to collapse the industry overnight. Thoron founder Thayne Kollmorgen says: good.

In this episode, he reveals the brutal truths behind America's failure - from the "open source honey trap" that kills innovation to the product design flaws that put US companies an "order of magnitude" behind. He also lays out the Tesla-inspired playbook a new generation of American founders is using to finally build a true competitor and win the drone war.

A new generation of founders is winning the new space race, and they're doing it by breaking one simple rule. In this founder's guide, A-ray Labs founder Andrew Peterson reveals the one broken "cost-plus" law that crippled the defense industry for 50 years and created the opportunity of a lifetime.

We ran out of time just as we were about to dive into Andrew's incredible 3D mapping technology - we'll have to get him back for Part 2!

America is facing a housing crisis driven by two core problems: a massive skilled labor shortage and 50 years of zero productivity growth in construction. QB founder Aleksandr Gampel has a radical solution. In this episode, he reveals his "Factory in a Box" - a mobile microfactory that can be deployed anywhere to build a high-quality home in just 30 days with only four unskilled workers.

Plus: why most construction-tech startups fail, the secret to building at scale without a gigafactory, his plan to become the "McDonald's of housing," and how this revolution will finally make the dream of homeownership affordable again.

America doesn't have a nuclear waste problem; it has a financial one. In this episode, Exodys Energy founder Carl Perez reveals why the 50-year-old fear of spent fuel is based on a lie, and why solving it will unleash the nuclear renaissance.

Venture capitalists recently returned from China declaring America's battery race "futile." They're wrong. In this episode of The Rational Optimist Podcast, Ouros Energy founder Ethan Loosbrock reveals the new American battery technology that will not only catch up, but leapfrog the competition by making today's best batteries obsolete.

Plus: how Ouros plans to deliver a 1,500-mile range EV, the clear pathway to $10/kWh batteries, why fast-charging is an "admission of defeat," and how this breakthrough will finally unlock a future of electric flying cars and a truly cordless world.
