    Dr Luke Haverhals: Making plastics out of plants

    ‘Plastic has long been the fossil fuel industry’s ‘plan B’’ says Luke Haverhals, co-founder of NFW, a start-up dedicated to creating materials with plants, not oil. Plastic has a stranglehold over our lives, but it’s not good for us, and it also keeps the fossil fuel industry in business. Luke is proposing a solution to this - creating four different materials that can be used to make anything from clothes to shoes to furniture, that can return to the earth at the end of their life. Is this the solution to the plastic crisis?

    Mark Bjornsgaard: The free heat revolution

    Data centres are not the most glamorous topic of discussion but they are everywhere, powering our modern, digital economy. But they can also power swimming pools, breweries and laundries, as Mark Bjornsgaard tells Hannah and Rob on this episode. 97% of the electricity that goes into a computer comes out as heat. It’s an incredibly inefficient process, and more often than not this heat isn’t used. So, rather than building these data centres in the middle of nowhere, Mark’s company Deep Green is taking computing power to where heat is needed, offering a precious resource to communities across the UK. Could this be scaled up for use across the world?

    Dr Sasha Luccioni: The climate cost of AI

    Despite the inexorable growth of Generative AI tools such as ChatGPT or Midjourney in the past couple of years, painfully little is known - or at least publicised - about their carbon impact. However, Dr Sasha Luccioni is on a mission to change that. Hannah and Rob talk to her about how she’s trying to maximise the benefits of AI, while minimising its hidden climate costs. Why is AI development such a black box? And could AI be part of the solution to the climate crisis?

    Professor Sir David King: What’s whale poo got to do with it all?

    How do we buy ourselves some time to save our planet? Humans are responsible for the immense damage inflicted on our planet since the Industrial Revolution, but now we have the chance to do some good and repair the climate. Hannah and Rob discuss the power of human ingenuity and ambition with Founder of the Centre for Climate Repair at Cambridge University, Professor Sir David King. His work finding ambitious solutions to the climate crisis can sound almost unreal. Making clouds brighter to reflect more sunlight? Refreezing the arctic? Using whale poo to regenerate the ocean’s biodiversity to store more carbon? He joins Hannah and Rob explore these solutions and more in this week’s episode.

    Kingsmill Bond: How is the energy transition going?

    ‘It’s obvious that oil is on the decline’, says energy strategist Kingsmill Bond. He joins Hannah and Rob to talk about the energy transition and he’s got an optimistic take: he says that we reached peak fossil fuel demand 10 years ago, and give it another five and oil will be a thing of the past. Kingsmill tells Hannah and Rob how we can move past a narrative that’s been peddled by the fossil fuel bosses telling us that renewables are too expensive, and why learning from the tech shifts of the past will be key to predicting the future of green energy.
