  • Self congratulating capitalist tripe

    If you want to hear a bunch of privileged capitalists get together and tell each other how great they are at saving the world and being eco warriors then this is for you. It’s pathetic, flimsy and superficial. The only episode I listened to was a tour around the inside of Europe’s largest data centre. It’s sickening how much money is being poured into protecting chips when there is so much human tragedy in the world. Vulnerable women, children and babies the world over are dealing with war, fami... more

Talking Points

Recent interactions between the hosts and their guests.

The Testbed for Asia's Clean-Tech Future | Ep272: Jaime Z. Urquijo
Q: How has renewable energy progressed in the Philippines and what role does Ayala play?
Renewables moved from a nascent stage to a cost-competitive core through policy support, with ACEN as the renewable arm; Ayala has shifted toward procurement strategies that favor renewables (e.g., green energy sourcing with retail suppliers) and has actively reduced emissions while balancing growth and grid stability.
The Testbed for Asia's Clean-Tech Future | Ep272: Jaime Z. Urquijo
Q: What does sustainability mean for Ayala and how is it implemented across the group?
Sustainability is anchored in Ayala's North Star to build businesses that enable people to thrive, followed by a practical framework from the World Business Council for Sustainable Development that focuses on minimizing negative externalities and continuously reducing them through measurable actions like Scope 1 and 2 improvements and striving for Science-Based Targets.
The Next Frontier of Electrification? Industrial Heat | Ep271: James Macnaghten
Q: Could you introduce yourself please in your own words?
James explains he's the CEO of Caldera, a startup focusing on decarbonizing industrial heat by storing electricity as heat and producing steam on demand for factories.
How Much Better Can Solar Get? Deep Dive Australia 08: Martin Green
Q: What were the key innovations that propelled solar efficiency forward, and how did they become widespread?
The innovations centered on tunneling structures (TOPCon) and later passivated emitter and rear cell designs, which improved voltages and current extraction; these, combined with industrial-scale manufacturing and licensing, helped disseminate the technology globally, especially as patents expired and the industry opened up.
How Much Better Can Solar Get? Deep Dive Australia 08: Martin Green
Q: How did you get into photovoltaics and why did you decide to pursue this path?
I started in microelectronics in the 1960s, but grew disillusioned with its social impact and shifted toward solar because of its potential for broad societal change, especially during the 1970s oil embargoes.
