Pumping heat out of the ocean and capturing it as energy

It's just peanuts that could be captured this way, isn't it?

It seems to me that better way would be stopping adding to the greenhouse effect and store some of those gases in the ground (by large scale (a|re)forestation).

Taking heat out of the ocean at a scale to replace all other power plants. It would be as much about what pollution it offsets.

Store the excess. Get it out of the ocean.

So use more.. to one day maybe save the lucky ones.

No, make everything especially energy as cheap and efficient as possible so that everyone gets richer and healthier and can contribute to solving humanity’s problems.

this is an interesting thought to rise the tide to lift more boats, ie for more people to ascend the hierarchy of needs and contemplate what sort of creative output we could secure from that ascent all else being equal. I'll have to think about that, that's an interesting idea.

At the forefront of any niche field in science is a very small group of specialists working the problem (historically too: https://en.m.wikipedia.org/wiki/Multiple_discovery) - the way we get ahead as a species is more specialised groups working more problems, which requires a larger educated base to draw from. i.e. we all go to the stars together or not at all, a dystopian future where most humans are impoverished/uneducated can't support the scientific progress needed to advance past our current technology

That's like.... the root cause of our issues

You think we might be better off burning wood and dung instead of solar and nuclear? Carbon free energy requires high technology global civilization. If you make everyone poorer then say goodbye to science and technology, no one cares about those when they’re worrying about how to heat their home and put food on the table.

Can't win a race with a moving finish line. It's never enough, we always want more

We could live completely on renewable energy if we lived like our grandparents, we don't do it, because we want more, more food, more gadgets, more services more entertainment, more tech, more money, more health, &c. it never ends, because we don't have a goal. "get healthier and richer", the vaguest goal you can come up with

Er, you mean materials science, biotech, and politics.

We need all tech on the table including tried and tested nuclear as well as untested space based solar and geoengineering.
