  • 3.37 Creating Super Cool Future with Josh Dorfman
    Jun 27 2025

    “So when I think about a future that is solving climate, I think about raising our quality of life. I think about more inclusive cities with wonderful parks, and it's a fantastic mass transportation that's really considered a luxury good because whether you're the wealthiest person in that city or the poorest, you all want to be on the same subway or the same bus because it's simply the best way to get around and everyone enjoys these types of amenities.There are examples of that all over the world. We try and bring those to light. And that is my vision for what the future starts to look like.”


    Josh Dorfman spent time in China in the 1990s, which opened his eyes to environmental issues and the impact of rapid industrialization and consumerism. When he returned to the U.S. and went through a phase of environmental activism before deciding to focus on shifting consumption towards more sustainable products. He started an eco-friendly furniture company called VivaVie in 2004, which led to the creation of his "Lazy Environmentalist" media brand.

    During the pandemic when supply chain issues made it difficult to source sustainable materials for his previous furniture company, he developed Planted - Josh's current carbon-negative building materials company. They identified fast-growing perennial grass as a potential replacement for traditional lumber and engineered wood products. They worked to vertically integrate the entire supply chain, from growing the grass to manufacturing the building panels, and partnered with major homebuilder D.R. Horton to secure a large order for their carbon-negative panels.

    Josh then launched a media company, Supercool, after stepping down as CEO of Planted to focus on sharing stories of climate innovation and solutions. Supercool aims to highlight commercialized, scalable technologies and initiatives that are improving people's lives while addressing environmental challenges. He shares his vision for a "Supercool future" that involves raising quality of life through inclusive, sustainable cities and infrastructure.

  • 3.36 Nature Inspired Robotic Design
    Jun 13 2025

    “We’re always inspired by nature and using nature as a starting point. So we can use the most advanced technology whether it’s robotics or parametric design using algorithms, AI. Regardless of the technologies our goal is to create something that’s beautiful and it’s just works as far as the simplicity. And there’s kind of a synergy in the work we do. So we’re hoping to use this advanced technology beautiful forms in the nature and having everything work together really well.” - Joseph Sarfian

    Joseph Sarafian and Ron Culver, are the founding partners of architectural firm Form Found Design. Joseph has a background in computational design and parametric modeling, while Ron has experience as an architect, contractor, and musician. They met in graduate school and decided to start their firm together, combining their complementary skillsets.

    Form Found Design has developed several innovative construction techniques, including using robots to cast custom concrete structures and a computational framing system that allows for mass customization without added cost. They have used these methods for projects like a 15-foot tall concrete structure for Amazon, as well as residential homes.

    In response to recent wildfires, Form Found Design has focused on designing fire-resilient homes using non-combustible materials like metal, insulated panels, and cross-laminated timber. Their goal is to create homes that are more durable, energy-efficient, and sustainable compared to traditional wood-framed construction.

    The main challenge Form Found Design faces is educating contractors and homeowners about their innovative construction methods. However, they believe the demand is there, as people are increasingly seeking more resilient and sustainable building solutions. Their overall vision is to use advanced technology like robotics and parametric design to create beautiful, nature-inspired architecture that is also highly functional and efficient.

  • 3.35 Why Earthen Buildings with Sasha Rabin
    May 18 2025

    “I think there's a whole new awareness right now after these fires in LA, at least for people who live in California of like, just actually how toxic our whole houses are. So, you know, the answer for some might be, “oh, I was going to buy a new couch and I'm going to buy a couch that's cotton instead of like plastic,” you know, just smaller things. And, yeah, the more people that could be building a whole house out of natural materials right now, that's amazing.” - Sasha Rabin

    Sasha Rabin has a long history with natural building, stemming from her father's early interest in straw bale construction in the 1990s. This sparked Sasha's passion, leading her to study environmental design and eventually focus on earthen building methods like cob, adobe, and light straw clay. She founded Earthen Shelter as a platform to teach workshops on these techniques, which she sees as an important part of creating more sustainable and healthy built environments.

    Sasha discussed the challenges of getting alternative building materials permitted, especially in high-seismic areas. While there are now code appendices for some natural building methods, Sasha and organizations like Quail Springs, where she is involved, have had to do extensive testing and work with local officials to demonstrate the safety and viability of these materials. Looking to the future, Sasha envisions a multi-pronged approach, from simple retrofits using earthen plasters to whole cob or adobe structures, as crucial for rebuilding more resilient communities.
