I call it Bytejunkium, but I don't think it catched on.
I bet it looks like a bunch of blue balls |

We can't make it so large that its own gravity will contain the reaction mass, so it has to be kept inside a very strong magnetic field created by huge magnets. You can't put solar panels inside the reaction chamber, they would get destroyed. |

I fell like it should be possible to make solar panels that don't contain iron, nickel, or cobalt. |

Fusion is still five years off, right? |

N+5 years off, where n is the current year. We'll get there one day! |

That's the most common proposal for MHD generators - once it goes thru the MHD proper you use the waste heat to drive a conventional powerplant. Unfortunately MHD requires the production of plasma to be effective, and plasma just does not like to exist, so the engineering practicalities make it... unlikely to ever be even remotely viable outside of incredibly niche applications (although non-pl...

It's going to be a hell of a lot faster with all those oil wells burning |

Even then all of them but solar are just spinning a wheel.
And even then some solar works by boiling salt... Or water. |

There are also some chemical modes of electricity generation (Alkalai batteries, etc). Also using flowing water to move Turbines like dams. But then the meme isn't as fun here, and those are such a small minority of how we generate powers.
You could maybe catch lightning and store it. Thatโs not boiling water โฆ whatโs that? It is boiling water? |

That's just the effect of fusion. It regrows hair. |

i mean, they can run the plasma through some magnetic fields... But it's less efficient that boiling water.
https://www.darpa.mil/research/programs/rads-watts too. But yeah, steam turbines are remarkably efficient and if you are designing a reactor today, you definitely assume one of them will be used. |

Worry not, the implanted power systems I know of generate at peak a few nanowatts. Enough to tricklecharge an extremely low power device or run some very very very efficient digital hardware, but no way you're harvesting that power for anything more useful. It'd be far more practical just to have the humans chained to bicycle generators... |

I wouldn't be surprised, it it turns out, when the most efficient way to turn lightning into electricity, was to redirect it into a boiler, instead of harvesting it directly |

Um, it's the heat, pressure, and ionizing radiation of the fusion reaction that would destroy the panels. |

IIRC, most of the people that actually work at ITER don't expect to live to see commercial fusion. We've achieved controlled ignition several times, but there's a lot of steps still between that and delivering fusion power to your local grid, and I don't think I would trust anyone to give a concrete timeline. I really thought Polywell Fusion would be the trick, but Australians (and probably the US DoD) have good evidence it doesn't "scale" in a way that will give a energy-positive/fuel-negative cycle. https://en.wikipedia.org/wiki/Polywell#University_of_Sydney_experiments |

Well I solved one problem, so someone else can figure out the rest. |

except for solar and wind, i guess. also the thingy where you catch electrons directly from nuclear decay.
Some types of solar are also just boiling water. https://en.wikipedia.org/wiki/Solar_power_tower |

I was so hoping helion was going to work. They were trying to recapture the pulse in magnetic confinement when fusion pulsed. Eliminating steam would be awesome. |

I swear we are going to be travelling to other planets and the biggest issue is going to be how do we stop water leaking into space from our steam turbines. |
