Reviving Forgotten Technologies: How Airships, Supersonic Flight, and Geothermal Energy Could Transform Our World | Eli Dourado (Head of Strategic Investments at Astera Institute)

Eli Dourado is Head of Strategic Investments at Astera Institute, a foundation funding transformative science and technology across energy, aerospace, AI, and other frontier sectors. Before joining Astera, he worked as a "regulatory hacker" at Boom Supersonic, where he helped navigate complex aviation regulations to make supersonic flight viable again.

In our conversation, we explore:

• How Eli's refusal to be pigeonholed led to a career reviving forgotten technologies

• How lifting the 1973 ban on supersonic flight could reshape aviation, after decades of stagnation and regression

• Why airships need to be massive to be economical, and how they could transform global logistics

• The untapped potential of geothermal energy and why drilling economics are the key bottleneck

• Why titanium could be the next material to undergo a manufacturing revolution

• How reading regulatory fine print can unlock trillion-dollar industries

• Why AI might not automatically solve our productivity problems

• The relationship between technological stagnation and potential civilizational collapse

• The fascinating possibility of harvesting antimatter in space
