Fusion power: a short-term blessing or long-term curse for the environment?

Yes - that is why ‘Paleo’ diet is :rofl:

Must have missed that one.Qould you be able to post or DM a link?

As I recall, Ötzi (a.k.a. the Iceman) was found to have atherosclerosis and osteoarthritis. So, clearly, his “paleo” diet did not protect him from degenerative diseases.


There’re also found bone diseases from too much bee larvae, from heavy metals, from not enough food, etc. With youngs being as current olds and lifespan of 23.

Solarpower is now
Nuclar fusion is only withni decades, and probably much more expensive

Top 10 lowest solar power prices in the world | Commercial Solar Guy
The purpose of this post is to track the top ten lowest priced solar power plants globally. Here they are, as of January 28, 2021:

  1. 1.04¢/kWh – Saudi Arabia, 600 MW, announced April 2021
  2. 1.239¢/kWh – Saudi Arabia, 1.5 GW, announced April 2021
  3. 1.316¢/kWh – Portugal, % of 10 MW, announced August 2020
  4. 1.35¢/kWh – Abu Dhabi, 1.5 GW, announced April 2020
  5. 1.50¢/kWh – New Mexico, USA, 100 MW, announced May 2020
  6. 1.57¢/kWh – Qatar, 800 MW, announced January 2020
  7. 1.61¢/kWh – Saudi Arabia, 300 MW, announced April 2020
  8. 1.65¢/kWh – Portugal, 150 MW, announced July 2019
  9. 1.69¢/kWh – Dubai, 900 MW, announced December 2019
  10. 1.75¢/kWh – Brazil, 211 MW, announced July 2019

Special mentions:

The whole world has seen solar power pricing come down precipitously. The Lawrence Berkeley National Laboratory and International Renewable Energy Agency published these wonderful images to help visualize bids and deals signed in the USA and globally. And while both are behind the above list by a bit, it gives a clear projection about how things have moved over time.

Sorry - can’t find the forum post again.

Buy our fungal mycelium bomb. Water your lawn. Problem solved.

Relevant scientist explained you shouldn’t add random fungus, and their ‘bomb’ isn’t a silver bullet solution. They did not appreciate the pushback.

PS found it!


Funny how nobody ever does.

I agree that our social evolution has greatly fell behind our technology evolution and a paradigm shift is greatly needed. Having said this I am no scientist just have a passion for all life and instead of working against nature we as humans should work with nature. For example water management and erosion control. It is common knowledge that trees in particular and plants in general reduce erosion and readily available. The problem is that it is low cost and goes against the capitalist system. I myself have never understood human’s insatiable appetite for waste and energy needs. All other life for the most part take what they need and go about their lives. We humans need to incorporate this. Being part of the iNat and other groups have taught me that cooperation is the way to go. I can go on and on about this but will stop here. Just my 2 cents worth from a hobbyist naturalist point of view.


Humans do what every other species does, every life type on Earth would take as many resources as it can, other species aren’t any better.


depending on the local natural vegetation. In grassland it is the native grasses which are most effective for erosion control. Planting trees in grassland habitat (or our fynbos) is the wrong choice.

But wild animals adjust their breeding to available food resources. Litters of feral cats and dogs, are again a human problem - not a cat / dog problem.

We have more than enough food sources right now, humans also evolved as hunters-gatherers that means humans had to change places as they quickly ate everything in a distance around them, so I don’t see anything as unnatural or unique in human behaviour, medicine and other intellectual innovations made bigger populations possible, so we live with that, and live pretty comfortable.

Don’t want to come across as misanthropic, but I think humans are less analagous to cats / dogs and more analagous to brewer’s yeast in a sugar-rich environment, especially looking at how we’re responding to climate change.

On an individual level, people can make better choices like vegetarianism/veganism, walking vs driving etc. Even so with small-medium groups, with things like reforestation and environmental activism, for example. Overall though?

I think a lot of the points brought up in Staying Optimistic are relevant. I think what makes humans unique vs. other animals is that we can see what’s happening and are capable of changing the outcome. Will we? Hopefully, my analogy is wrong and we don’t end up like the yeast, which in consuming everything, ends up poisoning itself as the alcohol concentation increases.


Looking at my feed for water from The Guardian - England doesn’t seem to be coping well with the current drought / heat wave. Rivers are either running dry, or sewage, fish are dying. Small creatures like bats can’t take the heat either.

Climate refugees are on the most vulnerable edge. Long way to a tiny sub-Antarctic island if we evacuate Cape Town.


I think it will be a blessing.

The fact is, it works. Think the Sun or Fusion bombs.

The difficulty lies in making the process controllable.
And it does not come with many of the problems that fission has. (The opposite nuclear process to fusion.)

It is still many years away from viability, but we’ll get there. Just because it doesn’t happen right away doesn’t mean we should give up.


I hope that controlled, long-term, net energy production by fusion is developed in the next few decades. That will be great. (I’m not going to hold my breath waiting, though.) Fusion itself doesn’t produce greenhouse gases, which are causing current global warming, and doesn’t produce dangerous wastes.

The big questions will be how we use the energy, but those are the big questions we deal with now. Sigh.


“Renewable energy” is a misnomer. As long as the turbines and batteries have to be made from mined minerals, they aren’t renewable. The generator in a wind turbine contains rare-earth magnets, and, well, just as the name suggests, rare-earths are in limited supply. Since fusion reactors require continuous refueling, the same limitation applies.


Another article on the present state and perceived future of fusion power:


Why, you ask, should human emotions evolve, and along with it our reasoning? In the stone age the war fighting technology could at best (or worst) kill a few fellow humans. Today it can eliminate all life on earth. There is a statistical principle that if it can happen, it eventually will. If our emotions, and our reasoning, were evolved, we would not allow such human made technologies to exist.
