  • #44: Electricity Shared - Jemma Green

    Dr Jemma Green is the Co-founder and Chair of Power Ledger. Dr Green began her career as an investment banker in London, working for JP Morgan. While based in the UK she completed a Masters of Sustainability Leadership at Cambridge University. After returning to her home town in Perth, Australia, she completed a doctorate on Renewable Energy at Curtain University before founding Power Ledger. 

    Power Ledger uses blockchain technology to enable the transition to low cost, low carbon and resilient distributed energy markets. It allows private citizens to buy and sell fractionalised energy on a peer-to-peer basis. In October 2017 Power Ledger held Australia's first ICO (Initial Coin Offering) and raised $34 million.

    Join us as we discuss how Power Ledger is changing the way we use electricity, what the hectic weeks of the ICO involved and how Jemma came to be in Richard Branson's pool on Necker Island!

  • #43: The Number That Rules Humanity - Robin Dunbar
    You only have 150 friends. How do we know that? Because that is Dunbar’s number.
    Robin Dunbar is a British anthropologist and evolutionary psychologist at the University of Oxford. His research proved the rule that 150 people is the ‘point beyond which members of any social group lose their ability to function effectively in social relationships.’
    Neolithic farming communities, Roman military armies and even global manufacturer Gore-Tex subscribe to Dunbar’s number.
    In this episode, we speak to Robin about what his research tells us about how we interact with one another, why maintaining relationships means different things for men and women, and how Dunbar’s number fits in with the law of threes.

  • #42: Going Paleo - Pete Evans
    Pete Evans is a world-renowned chef, restauranteur and co-host of hit TV show, My Kitchen Rules – he is also no stranger to controversy.
    Pete is a strong advocate of the ‘paleo diet’, which excludes sugar, processed carbohydrates and dairy - he has also received criticism for his views on fluoride in water.
    In this laid-back, long-form chat, we unpick truth from fiction and uncover Pete’s philosophy on life and how he aims to get the most out of it. Hint: it isn’t by worrying about what other people think.

  • #41: Did The Cold War Ever End? - Kim Beazley
    The Hon Kim Beazley AC is a former Leader of the Australian Labor Party and Leader of the Opposition (1996-2001; 2005-6) and Ambassador to the US (2010-16). His parliamentary career ran from 1980 to 2007, during which he held a number of cabinet positions in the Hawke-Keating governments. He is widely regarded as one of Australia’s greatest Defence Ministers (1984-90). Kim is also a graduate of Oxford, where he was a Rhodes Scholar. 
    In this episode, we join Kim to tackle the issues of Putin’s belligerence, whether the Cold War ever really ended, and what we should do about it. We could think of no greater expert than the Bomber to answer these questions!
