- obilgic 13y agoThanks, definitely interesting. Seems like we will have a lot of time to answer my question.
- m_mueller 13y agoHow much of that 10^24 is required to power earth's ecosystem though? Not that this is relevant now, but I could see it becoming relevant when/if we move towards leeching 10^21 of that energy for human needs in a hundred years - which isn't really much in global terms. Mankind might need to move towards a level 2 civilization earlier than some people imagine. That or we figure out large scale fusion energy.
- legitsource 13y agoI doubt we get to the point where we start taking too much light for plants to survive any time soon, and the heat will end up here anyway.
