Drives me crazy that people are still pining away for some magic blue-light arc-reacor sci-fi energy source to save us when solar and wind are out there doing it, as we speak.

"If only we could generate energy cheaper than any fossil fuel, but free of carbon emissions!"

Uh.

And solar's not even close to done yet!

"MIT engineers have developed a scalable fabrication technique to produce paper-thin and lightweight solar cells that can quickly and easily turn any surface into a power source." https://pvbuzz.com/mit-produce-paper-thin-and-lightweight-fabric-solar-cells/?utm_source=substack&utm_medium=email

The fusion discourse is extremely annoying, but it'll be gone again in a day or two, so let me just add two final notes to this.

First: no one, least of all me, is "against" fusion or fusion research. Research away! Yay for science.

Two: what bugs me is nothing about fusion itself but what I see as a very familiar kind of anti-politics. There's a craving for a deus ex machina that solves all problems & transforms everything without all the tedious arguing, fighting, & battling for every inch of ground.

This craving to bypass politics is understandable, but it's bad. Even if fusion proved viable tomorrow, there would still be politics. There would still be fights & disagreements & factionalism. It would still be a long battle to transform the energy system.

People want to transform energy without disrupting the basic systems of political power -- that's a big part of the impetus for "just slot nuke plants in for coal plants & call it a day." System justification is a powerful subconscious force.

Why social change is so excruciatingly difficult

When we look across the broad sweep of human history, what needs explaining is not times of rebellion and upheaval, but the much more common periods of unjust rule facing little resistance. Why do people so often internalize the ideologies upholding systems under which they suffer? Why do they fail to fight back? Psychologist John Jost has an answer. I talked it over with him.

Anyway, part of the appeal of the future-tech stuff is that there's no nasty politics attached to it -- because it's theoretical & in the future. But if it became real, nasty politics would attach to it. Such is life. No way out but through, etc.

@drvolts Not mentioned in the discussions I've read the past week:

1. Tritium (the most likely Hydrogen isotope for use) is usually created in nuclear (fission) reactors.

2. Fusion reactors themselves will likely become irradiated over the course of their operation, requiring hazardous disposal.

These environmental threats are a ton less than for conventional nukes (or coal, ftm), but they will certainly result in some "nasty politics".

@three_star_dave @drvolts Yes. Though tritium may be produced by neutron irradiation in a lithium blanket around the fusion vessel.
