SUSTAIN #5: Can we radically reduce the emissions created growing our food?

Growing the meat we eat produces a lot of Australia’s carbon emissions. The four innovations explored in this episode – Rob Kinley’s amazing seaweed, George Peppou’s vat-grown meats, Sebastien Eckersley-Maslin’s vertical farms, and Nick Hazell’s plant-based ‘meats’ – show us a path toward an agriculture that can be radically more efficient.

SUSTAIN #3: Can we collect and store enough renewable energy to replace coal-fired electricity?

In 2020, renewables became the cheapest source of electricity – and frequent guest Ramez Naam brings us all the stats about this fully underway transition to solar and wind power. But without cheap storage, renewables will never be able to be the entire solution for a world that looks to need a lot more electricity. Australian startup MGA Thermal may have invented the ideal technology to accelerate our transition from coal to solar.

Here’s a Techcrunch article about MGA Thermal getting backed by Australian VCs Main Sequence – and their power station trial in Switzerland.

And finally, here’s a story about the day that solar generation (briefly) eclipsed generation by coal-fired plants in Australia’s winter!
