Craig: not surprised that this that this is happening, but this is going to help reduce the cost of nuclear fusion technology once it's viable. so princeton university researchers have achieved a breakthrough in, nuclear fusion technology by successfully print three d printing critical components of a fusion reactor. it's, it's been detailed in, the journal of nuclear fusion, and it marks a major step in making fusion energy more accessible. okay? so the the what they did was they focused on creating complex stellarator components using three d printing techniques. and we talked about what stellarators are, but, essentially, they are a type of fusion reactor that uses magnetic fields to combine the heat, plasma, and to temperatures that are harder than the sun's core, to be honest. so that's how right now a lot of the, reactors are built is using that. so, they successfully printed intricate magnetic coils and support structures, which is awesome, which are critical for, maintaining the plasma shape and stability within the reactor.

Jon: yeah. you know, you know more about this, so i'm sorry if i pause for a second. you know more than i do about

Craig: more detail.

Jon: now imagine a future where we have virtually limitless energy as easy to access as turning on a light switch, but without fossil fuel print footprint, this isn't science fiction. it's a promise of three d printed nuclear fusion reactors, which might just be the world's next energy breakthrough. and guess what? princeton's three d team is already on it. so nuclear fusion is the holy grail of clean energy. you know? we've been taught this has been talked about for a long time. it's what powers the sun combining, atomic nuclei to unleash massive energy. unlike vision where atoms are split, think explosions and radioactive waste, fusion uses hydrogen isotopes, which can be extracted from something as common as seawater. theoretically, fusion could give us clean, sustainable energy without the long lasting waste or safety concerns we see with nuclear fission.

Craig: yeah. so for those of like, i'm sure most people know this, but, like you said, this isn't really science fiction. for those that don't know, the sun is essentially a huge fusion reactor. so it happens in nature. it's just a matter of how do we recreate that in a lab setting. right? so, this is really cool. the cool thing about the three d printing method is that what they've done is they've allowed the creation of highly complex geometries, obviously, because of the three d printing, which is typically impossible to manufacture using traditional techniques. so the cool thing about what they did was, they printed the components with remarkable precision, and this is interesting. deviations of less than point three millimeters from the design specs. so that's interesting. it's really cool. we talked about three d printing chairs, three d printing a bunch of stuff and, a lot of stuff in the past. so, not surprising that they're going this route.

Jon: yeah. i like the analogy that, if nuclear fission is like splitting a huge stack of firewood and actually accidentally burning the whole forest. nuclear fusion is more like creating a cozy campfire that can keep us warm indefinitely. so yeah. the really cool part is this three d printing connection that you were just talking about. the challenge in building fusion reactors line, the incredible, precise, durable components needed to handle the extreme temperatures and pressure. so enter your process where you're talking about these things are extremely precise. they can get these precisions down. traditional manufacturing methods are like trying to make perfect sandcastles with a bold bulldozer. sometimes you need, sculptor's touch. that's exactly what those three d printing tools you're talking about provides. the princeton's latest, project uses three d printing to build reactor protons that are not only customized, but also faster and cheaper to produce. this, technology allows engineers to experiment with complex designs and reduce material waste, aligning perfectly with sustainable goals. you know? and did you know that reducing, by reducing waste, three d printing, makes reactor building not only faster, but more eco friendly? traditional manufacturing methods can waste up to sixty percent of materials. but with three d printing, that waste is cut down to nearly zero.

Craig: exactly. yeah. there's there's very little waste except for the support brackets, which is a lot less. and if they can get the accuracy even better even more, like, this is yeah. like, they're, for those of you that don't know, they're three d printing, airplane, components now. they're three d printing a lot of, like, critical critical components that are helping to reduce weight, that are, that are reducing, that are reducing the carbon footprint. like, it's just crazy.

Jon: yeah. i mean, the stuff they're doing now is insane. like, they're three d printing genetics, dna. so they can yeah. the stuff they're doing is, you know, massive and, you know, minuscule. yeah. so why should we care about three d printed fusion reactors? for starters, the technology could slash the time needed to build functional fusion plants. we're talking about, how long it takes to build a nuclear plant and, you know, what the regulations are around that, bring us closer to a worldwide, where renewable endless energy is norm, not the exception. imagine cities powered by fusion with no pollution or emission, clean energy at scale. and princeton researchers test designs that improve plasma confinement. that's the tricky part. right? the keep the fusion stable. they're getting us closer to reactors that could actually work outside the lab.

Craig: yeah. well, they they have and we've covered this. they have successfully completed fusion reactions in a fusion reactor. just not enough to sustain it and not enough where the output is, is greater than the input.

Jon: and that's what i said. they're getting close to reactors that could actually work outside the lab where we're starting to get into production versus, you know, testing. sorry. yeah. no worries. for us, this could mean everything from lower electricity bills to fewer power outages, and a massive reduction in greenhouse gases. plus, it could make energy more accessible globally, meaning, helping areas that will struggle with unreliable power and allowing us potentially do a lot of things we wouldn't otherwise do.

Craig: yeah.

Jon: so we're looking at a technology that could redefine how the world is powered, which is fantastic. but here's the big question. with the potential of fusion so close, are we ready for the societal shifts it might bring? could this be the end of fossil fuels as we know it, or will we see a whole new set of challenges emerge as we make the transition? let us know your thoughts. confusion, energy change, everything, or are we setting ourselves up for a bunch of new hurdles and, you know, disappointment?
