    Removing Carbon from the Atmosphere to Reverse Climate Change (feat. Nori)

    We chat to Paul Gambill from Nori about their carbon removal marketplace using blockchain technology.

    This is the second episode in our two-part series about whether crypto and blockchain can be a positive force for addressing climate change. In this one we cover:


    The role of (and challenges with) carbon offsets
    Carbon avoidance offsets vs carbon removal
    Nori’s carbon removal marketplace and the Nori token
    How Nori can help put a price on carbon
    The energy intensity dilemma of blockchain to date
    Regenerative Finance
    The curious world of seasteading

    More Links!

    Crypto and Climate: Can Blockchain be a Force for Good?

    Crypto and Climate: Can Blockchain be a Force for Good?

    Nick and Alex chat about the impact of crypto and blockchain on climate. Is crypto accelerating climate change or can it be a force for good?

    Hot off the heels of “the Ethereum Merge” we cover the following in this ep:


    What is cryptocurrency? What is blockchain? 
    Why can crypto be so energy intensive? Can it be improved?
    Bitcoin and Ethereum (including the Ethereum Merge) 
    Dogecoin, GarlicCoin, OnionCoin and Dentacoin 
    Regenerative Finance
    Offsets, Peer to Peer Energy Trading; and
    Attempts at nuance

    This episode is intended to be a primer ahead of our next episode that dives a little deeper on how blockchain can be used to address climate change, with a company called Nori, so look out for that one!

    P.s. if you notice some slight whirring halfway through when Nick is speaking, it’s a big “we love Australia moment” - it’s not your headphones but CRICKETS outside Nick’s window.

    Night-time Solar: can we create Electricity in the Dark?

    Night-time Solar: can we create Electricity in the Dark?

    Nick and Alex chat to Ned Ekins-Daukes from UNSW about their breakthrough to create solar energy in the dark.

    This is a wide ranging chat about how solar panels could generate all of Australia's electricity at night, where climate solutions come from, the role of UNSW and universities in creating them, the legend of Martin Green, how to commercialise early stage technology, and a little lesson on the correct way to pronounce “solar photovoltaic”.

    Solar Panel Recycling: Big Problem or Massive Opportunity? (feat. PV Industries)

    Solar Panel Recycling: Big Problem or Massive Opportunity? (feat. PV Industries)

    We chat to Tim Dawson, the founder of PV industries, an Australian startup on a mission to recycle solar panels (and soon, batteries too!). 

    In Australia we have A LOT of solar! Currently over 3 million (or 1 in 3) households have solar. Australia has over 25 GW of solar capacity now installed which on a per person basis is 1kw per person, 30% greater than any other country. But what will happen to all these solar panels once they reach the end of their life?

    Tim Dawson, co-founder and CEO of PV Industries is on a mission to ensure that solar panels can be 100% recycled. PV Industries has created a recycling line that can pull apart a solar panel into its raw components and then sell them to various industries for reuse. 

    In the episode we cover: 


    How Tim and his co-founders started the business
    What happens to solar panels at the moment once they stop working
    The key inputs to a solar panel and those that are the most valuable to recover
    The future of solar, solar recycling and what other industries might need to consider either recycling or a whole reinvention of their mode of doing business

    The Australian Guide to Electric Vehicles (feat. CarsGuide)

    The Australian Guide to Electric Vehicles (feat. CarsGuide)

    Tom White from CarsGuide presents the state of play for electric vehicles in Australia. 

    Tom has a very cool job! He gets to drive and review all the latest electric vehicles that are coming to Australia. He also recently released the EVGuide Report for all the latest stats, facts and figures on Electric Vehicles

    So what better person to chat to (after our Season 1 chat to Tim Washington) to focus on where things are at for EVs including:


    What are the top selling models currently?
    What are the coolest new releases?
    How and WHEN Australians can get their hands on the latest models?
    Answers to key questions on range, recharging, vehicle to grid, how long EVs last for, when we’ll see a second hard market and much more
    The FUTURE of electric passenger transport (and will it involve hydrogen?)
