Episode notes
Iceland's Blue Lagoon Experience
- Noam Hassenfeld describes his experience at Iceland's Blue Lagoon, a spa filled with mineral-rich wastewater from a geothermal power plant.
- This anecdote highlights geothermal energy's potential as a clean power source with almost magical byproducts enjoyed by tourists.
Geothermal Energy Challenges
- Geothermal energy is abundant underground, but tapping it is difficult unless near natural hot water sources.
- Engineers try drilling very deep and circulating liquid to generate power from heat even in less ideal locations.
Technical And Safety Challenges
- Drilling deep underground for geothermal energy is costly and technically challenging, especially due to poor drill bit technology.
- Pouring liquid underground can also trigger earthquakes, adding risk and public concern to development.
