      The author leaves a lot out. Fusion is a money pit because of mismanagement. Most of the money goes to the Tokamak......a device that no power company will buy

        Here’s the problem why we don’t have advanced technology. It’s all about the money how much this and how much that. I’m sure when you throw away the how much we can achieve getting almost anything.its like you limit yourself to live when you know you don’t have too.

                Recyclable energy sources are more viable in the long run, is what I think.

                An other point of reason is that when you have more, you tend to spend more. So thousands of years of energy counted with today's energy probably isn't a thousand years worth of energy when humanity get used to using more energy (in some way I can't foresee in my crystal ball).

                Back to the first point:
                Humanity has used the 'fast, easy and doomed to fail one day'-formula over and over, tending to destroy something unforeseen in the process.
                Trivia; in this case the moon might crumble bit after bit from the mining, affecting the tides and all life on earth, and as humanity have to spend lots of energy on fixing the moon, at the same time as fusion power is running low (like our oil-running-low situation).
                Since the people responsible shift the blame to "The government", "big companies" or some other valid scape goat humanity can bicker about, rather than helping with the cause to save us all, history might repeat itself. That is if we all don't die from the green house effect.

                The 'doomed to fail one day'-formula has been done by many countries, many points in history and most of humanity has been warned time again by the few egg-heads who does the actual research on Tellus' climate.

                If we go by renewable energy, Tellus will be habitable for a longer time.
                Eventually humanity will have to leave the planet, since the sun will explode. When that time comes we will still have moon-fusion energy to move to another planet with (hopefully to a planet with another moon with fusion compatibility).

                This system of using moons for escaping certain death is a 'doomed to fail one day'-formula, since it's mining energy and not renew energy.
                My conscience in this lay to rest in that our moon will be swallowed by our sun in any case, and there's nothing I can do about it.

                  I feel like the toroidal fusion reactor is probably a failure, however after thinking about it for a while i wonder if the toroidal design might actually be better suited to antimatter. If we ever find a way to both create it reliable AND confine it, it will probably be magnetic confinement anyway. The only question then would be how to turn the reaction into energy we can use.

                  But thats a lot of big questions with no answers.

Also you brought up the point of it being a 10 billion dollar gamble, which could be spent on other clean energy sources of wind and solar power, etc; but you have to think that they had to be funded be proven as well. So you got to start somewhere wether it'll fail or not.

It's the best one. I've put a lot of thought into it. The amount of energy our weather throws around is vastly more than humans would have any idea what to do with, it only needs to be used. It uses no fuel of any kind, and if it isn't USED the moment it is present, it is wasted. And best of all, while you're processing the atmosphere in large quantities as you funnel wind down corridors filled with windmills, you can process the air and remove the carbon dioxide from it. It is what you need, it is the ONLY answer to kill 2 birds with 1 stone.
