My Issue with Techno Optimism

I think my least popular opinion within the solarpunk space is, that I do not like Techno Optimism. But there is a good reason for it.

The usual way techno optimists go about it is looking at the state of the world and say: "Well, it is not all bad, technology will save us one day." And this makes me so angry.

It is basically saying like: "One day there is gonna be magic and everything is gonna be okay."

This especially comes into play with the environmental stuff. "Oh, don't worry about clean energy. One day we are gonna have fusion reactors and with that unlimited clean energy." And also: "Oh, don't worry about the CO2 and climate change. One day we are gonna have machines to filter the CO2 from the air."

But actually, what they are saying is: "Let's not change anything right now. It is all gonna work out in the end."

We already have clean energy. We have photovoltaic, we have wind, we have hydro and we have nuclear. (And yes, contrary to what folks might have told you: We do know how to store nuclear waste safely.) We can invest money right now to build a renewable energy grid.

We also do know, how to store some of the CO2. Yes, trees, but also wetlands. Wetlands and especially marshes are AMAZING in storing CO2.

And no, we do not need some weird flying bus. Trains will do just fine.

To me the thing about solarpunk is, that already have all the tools we need to make it happen now. Techno optimists wanna wait for a solution to appear that allows them to not change their behavior. To just keep doing, what they have been doing the entire time. To not degrow. But that is just bullshit.

We need change. We need equity. We it now. Not in 20 years.

Potential breakthrough in production of fusion energy?

         Generating energy at a scale and cost similar to current electrical generation technology has been the “holy grail” of fusion energy research for decades. In short, achieving a “net gain” of energy in a fusion process would lead to a carbon-free, unlimited, clean power source. See WaPo, Fusion energy, the ‘holy grail’ of clean power, a step closer to reality.

         Energy Secretary Jennifer Granholm will announce on Tuesday that US scientists have made a breakthrough by producing a net gain of energy from a fusion reaction. Caution is warranted, however. The early reports suggest a small “net gain of energy” from nuclear fusion—the first time that result was achieved in a laboratory. Whether that process can be scaled up to replace other energy sources is open to question. But . . . if the breakthrough is real, this development could be a huge advance in our ability to address the climate crisis.

         Let’s wait and see what is announced on Tuesday. But this development may be one of those days similar to the NYTimes announcement of the confirmation of Einstein’s general theory of relativity. In 1919, the NYTimes sub-header read, “Men of Science More or Less Agog Over Eclipse Observations.” (They don’t write headlines like that anymore!)

We have no choice but to quickly expand generation four nuclear power for heat and electricity.

I mean, it's certainly a good stepping stone for a complete renewable transition. Not for indefinite usage though although maybe we'll develop fusion by then (if humanity's still around since the condition for that is for us to have eliminated climate change)

The fusion reaction...generat[ed] 3.15 megajoules of energy, more than the 2.05 megajoules provided by the lasers used in the reactor...The lasers require more energy to run than what they provide to the reactor, but even seeing net energy gain within the system is a significant milestone.

Plasma oscillations propel breakthroughs in fusion energy - Technology Org

Plasma oscillations propel breakthroughs in fusion energy - Technology Org

New insights into plasma oscillations pave the way for improved particle accelerators and commercial fusion energy.

Most people know that solids, liquids, and gases are the three main states of matter, but a fourth state of matter also exists. Plasma—ionized gas—is the most abundant, observable form of matter in our universe, found in the sun and other celestial bodies.

Creating the hot mix of freely moving electrons and ions that compose a plasma often requires extreme pressures or temperatures. In these extreme conditions, researchers continue uncovering the unexpected ways plasma can move and evolve. By better understanding plasma motion, scientists gain valuable insights into solar physics, astrophysics, and fusion.

In a paper published in Physical Review Letters, researchers from the University of Rochester and colleagues at the University of California, San Diego discovered a new class of plasma oscillations—the back-and-forth, wave-like movement of electrons and ions. The findings have implications for improving the performance of miniature particle accelerators and the reactors used to create fusion energy.

“This new class of plasma oscillations can exhibit extraordinary features that open the door to innovative advancements in particle acceleration and fusion,” says John Palastro, a senior scientist at the Laboratory for Laser Energetics, an assistant professor in the Department of Mechanical Engineering, and an associate professor at the Institute of Optics.

Plasma waves with a mind of their own

One of the properties that characterizes a plasma is its ability to support collective motion, where electrons and ions oscillate—or wave—in unison. These oscillations are like a rhythmic dance. Just as dancers respond to each other’s movements, the charged particles in a plasma interact and oscillate together, creating a coordinated motion.

The properties of these oscillations have traditionally been linked to the properties—such as the temperature, density, or velocity—of the plasma as a whole. However, Palastro and his colleagues determined a theoretical framework for plasma oscillations where the properties of the oscillations are completely independent of the plasma in which they exist.

“Imagine a quick pluck of a guitar string where the impulse propagates along the string at a speed determined by the string’s tension and diameter,” Palastro says. “We’ve found a way to ‘pluck’ a plasma, so that the waves move independently of the analogous tension and diameter.”

Within their theoretical framework, the amplitude of the oscillations could be made to travel faster than the speed of light in a vacuum or come to a complete stop, while the plasma itself travels in an entirely different direction.

The research has a variety of promising applications, most notably in helping to achieve clean-burning, commercial fusion energy.

Coauthor Alexey Arefiev, a professor of mechanical and aerospace engineering at the University of California, San Diego, says, “This new type of oscillation may have implications for fusion reactors, where mitigating plasma oscillations can facilitate the confinement needed for high-efficiency power generation.”

!Warning: topic = world ending event! Regarding: space, folklore, modern government/religious systems In detail: about the nuclear fusion reactor and it's potential impact for planetary collision. Tought of and written by: Ward A. De Vos (online handle: wabsol)

Tbh I got quite the shock the time of valentine this year. I've never seen the planets so vibrant before, tho I must say I've never seen the planets anyways(except the moon). Seeing the stars so bright after a super bright sun(january), the full moon and an orange planet(valentine) got me thinking. Aren't the stars meant to shine that bright during each advent(time before chirstmass)? Had such an impact on me that I started thinking where the water particles go to if they pass by the moon. Theorised they might go to a-star *. Meaning some star that's behind Pluto. Thought about the path it takes and what would happen to our solar system now that the iter is being build in france. iter(i earth or i tear when translated from french) is the first nuclear fusion reactor meant to run constantly. It get's hotter then the sun's core btw. So now, what if, the water molucules push that star away from the earth and the sun also influences that star's path. Would it not be hitting earth?

Don't even want to talk about the flag's of country's and how they look linked to eachother as a system like the snake Ouroboros. The fact that the Turkish red flag is the earth on it's side awaiting a star with five points like * Asterix(galia -now northern belgium where i'm from). Link that onto that gold orb with white halo and that cross or star on top. The pope or the queen of england has and you could just believe me for once again.

For fun you could try and translate my modern name to it's original meaning. Hint: use knowledge of vowels and history of language. "A means OS as in an ox btw"
