  • In the small grocery store around the corner where I live the cashier’s are listening to music, having phone calls with their earplugs in or watching videos with their phones lying near the register. The work is boring and repetitive, customer interaction is quite minimal there anyway because they are really fast in ringing you up anyway. And that’s everything I care about anyway. They can enjoy their day a bit more and I can get to doing what I enjoy fast, too.


  • The total mass of reactants in the fusion chamber is below milligram, some of which is bound in stable isotopes. Even if all of it escaped, it would be far from catastrophic.
    The reaction itself cannot run away on its own because it requires a delicate balance in temperature and density, which will be immediately disturbed if there was a breach in containment.

    The walls will be activated by neutrons, but short of blowing the reactor up, there’s not much chance of materials escaping in a significant amount to pose a danger.


  • If anything has been consistent about fusion its always them desperately trying to spin babysteps and monumental leaps forward

    That’s usually the media outlets sensationalising the results to the point where the articles are grossly misleading.

    trying to make themselves seem super clean and safe especially compared to fission.

    That’s just a fact, no need to try. The Fusion process is inherently safe the radioactive byproducts are generally short lived and easier to handle.





  • As he mentions in the video, the field is lagging behind other (renewable) energy sources by a few decades. Many of our energy production methods are “make thing spin fast” and then turn that energy into electricity. Coal power plants burn coal, create steam, the steam drives a steam turbine and the turbine a generator. A nuclear plant works the same way, just by extracting heat from fission instead of burning the fuel. Wind turbines, too. The technologies for this, like metal forging and casting, handling of steam, steam engines and turbines have been around for a long time and we have become experts in them. Solar panels are an exception to this as they used a different mechanism to generate electricity. Nevertheless, all of these technologies can be safely developed and deployed on land. Handling harsh marine environments up to a point where you can reliably drive these generators for an extended period of time just doesn’t exist yet. Historically speaking, this has not been necessary. So not only have to figure out how to best design wave energy extractors, we also need to get better at adapting them to the environment.
