1. Geothermal as a practical, low‑cost power source (especially in Iceland)
- “Wish geothermal energy was being discussed more for a power source for data centers.” – sghiassy
- “[…] huge amounts of electricity are available for low cost” – alexpotato (referring to Iceland’s geothermal)
- “I think i just saw Fervo delivered their 100MW facility a day ahead of schedule in 23 months.” – Johnny_Bonk
2. Comparisons that highlight how “easier” geothermal seems versus far‑out alternatives
- “It’s hard to come up with any idea that is not easier than going to space for solar energy.” – idontwantthis
- “I’m not going to bother to check the math but Gemini estimated $20 billion/y to generate 1 GW with hamsters on wheels so honestly that could be competitive.” – idontwantthis
- “Would a good enough insulator make it thermodynamically feasible to do it from an airship in the Venusian atmosphere?” – MatrixMan
3. Skepticism about the depth, reliability, or presentation of the proposals
- “This is a very brief, high‑level overview. It weirdly dives deep into some less‑relevant topics and glosses over a LOT of things.” – fghorow
- “I was interested until I saw the picture for labor month was a clearly generated picture with protest signs saying ‘Workers Unit’ instead of ‘Workers Unite.’” – ofjcihen
