  • It can be done and has been researched. See Project Plowshare.

    People who say we can’t build fusion reactors are only partially correct. (And no, I do not mean that we can build tokamaks that are net energy negative.) We can build energy-positive fusion reactors, and we’ve known how to do so since the 1950s.

    The idea was that you would build an enormous underground chamber. Then fill it with salt. Then detonate a small hydrogen bomb inside the chamber, instantly boiling the salt. You then run the salt through turbines to generate electricity. You power a city by setting off a nuke every one and awhile.

    The results of this work were that yes, it seems possible to build a power plant that runs off of hydrogen bombs. We do in fact know how to build a fusion reactor today. The problem? Simple economics. This method just isn’t cost-competitive with traditional electricity sources.

    This should serve as a cautionary tale for those hopeful for the future of fusion or advanced fission concepts. It doesn’t matter if you manage to build a tokamak that returns net energy. Ultimately it’s just a cool science experiment. What DOES matter is if you can do it cheaply. And this is actually why I’m skeptical of fusion as a power source. Even if we do ever manage to make non-bomb fusion plants produce net energy, they would struggle to be cost competitive with renewables+batteries.





  • Things need to be paid for, but why does that mechanism need to be baked into the platform?

    Imagine I’m the best, most engaging poster and commenter on Lemmy. Everyone loves my posts and comments, shares them, quotes them, and responds to them endlessly. (Maybe in this scenario everyone has brain damage for some reason, and this allowed me to become the top Lemmy user.)

    If I’m in that position, what’s stopping me from just putting a little blurb at the bottom of each comment saying, “this post is brought to you by Carls Jr.” or whoever wants to sponsor my comments. If people for some reason loved my posts and comments enough, I could find sponsors and just put those sponsorships right in whatever comment or post I make. Lemmy doesn’t need to be involved. They don’t need to go out of their way to recommend my posts either. If they’re good enough, then they can be spread naturally by people sharing and engaging with them.

    It makes sense for platforms to provider revenue to creators, but only if the platform has substantial ad revenue. YouTube pays its creators, but it also brings in billions of ad revenue. I don’t think most Lemmy servers even have ads.


  • Yeah it just makes sense. Everything has a little bit of consciousness in it, even subatomic particles would have a non-zero amount. But the consciousness of these particles then combine in complex and nonlinear ways. Something like, IDK, the combined consciousness of a collection of particles is proportional to their individual level taken to the n power, where n is equal to the number of particle interactions. Totally guessing on the actual math, but it would be something complex and nonlinear like that. If you could quantify consciousness, and humans had a measure of 1 consciousness unit, then the consciousness of an electron would be something like 1/Googolplex consciousness units. Something insane like that. Technically nonzero, but so small as to make an amoeba look like a intellectual giant.








  • Yeah, mutual aid works on the local level or in insular communities like long-term discord groups with a tight group of regular members. With community mutual aid, I’m generally in favor of just taking people at their word. If they say they need help, give them help. No need to interrogate them like the food stamp office will. You prevent people from abusing the system by simply not granting endless requests from the same person. Or if someone needs severe aid, at that point you can start actually verifying their story, helping them access government benefits, helping them find employment, etc.

    But that kind of open approach works for in-person aid. It doesn’t work for anonymous online aid, where someone can use bots to spin up hundreds of convincing profiles each begging for money.

    I just don’t think mutual aid works well in an online context. The only online context it works in is among communities like small discord groups where people know each other for years. But on a lemmy or mastadon-type service? Mutual aid is impractical. Any people asking for aid should be directed to local groups that can help them in person.


  • Let’s bring more chaos to this process! At some random time during the month, the power grid will just automatically turn off. No warning. Just instant lights out.

    Its duration will be determined by a log-normal distribution or similar. So the average duration will be 24 hours with a long thin tail going towards longer durations. There will be a very small chance power is out for the whole month. There will be an even smaller chance power will be out for a whole year. Also, the duration will not be announced at the start of the outage. You’ll just have to sit there in the dark for who knows how long.

    All home power generators will also have to be hooked up to this control system. Any home with active power during a deliberate grid blackout will be bombed by automatic drone.
