Geothermal Energy & Water Alone May Be Insufficient

Mark Eby — 2/10/2004 4:40:22 PM (archived)

The geothermal life on Earth depends on dissolved O2 as I understand it. Impossible without surface life. It's suggestive for life ion Europa, but not a slam dunk. Something would have to replace O2 for any life to exist on Europa. Low levels of peroxides might work on Mars.

Regards,
Mark
