| I think the administration's energy density should be extended for all things. Lets take transportation: Can't use federal lands, waterways, airspace or highways unless the airplanes, trains, ships, trucks and cars are powered by the highest energy density (nuclear). Also, anything that uses airwaves: So, nuclear powered phones, watches, airtags. This would be the biggest breakthrough for humanity. We have nuclear powered submarines but miniaturization of nuclear stalled since then. |

I mean, random car crashes have historically been the epitome of excitement, 4k war footage made me pretty indifferent towards bloody windshields and burnt out station wagons. I really think, the intensity of an unexpected fission event projecting its authority through my eyelids could make me feel something again. | |
| ▲ | nickff 4 days ago | parent | prev | next [-] | | Nuclear submarines were developed at about the same time as civil nuclear power plants (and you could actually argue they were developed earlier or reached maturity earlier). Nuclear submarine power was a sort of ‘killer app’ for nuclear power, rather than a derivative of civil nuclear power stations. | |
| ▲ | TheDong 3 days ago | parent | prev | next [-] | | Most of the things you cite, like phones, cars, airtags, can already be powered just off batteries and the electric grid, so the actual source of the energy is already abstracted away. A large-scale nuclear plant will be way more efficient than a bunch of mini-plants, so having battery electric cars + nuclear power plants already gives you nuclear powered cars without even having to invent anything new. We only need to focus on fuel generation (power plants), and the small number of remaining places that don't just take power from the grid (planes, ships, other things that have their own fuel/generator on board). | |

| ▲ | mrDmrTmrJ 4 days ago | parent | prev | next [-] | | We control nuclear proliferation by making enriched uranium (U235) very, very hard to acquire. While I'd love to see more nuclear reactors in our society. The "nuclear everything" argument breaks a core tenant of US national security policy, making U235 very hard to get. | | |
| ▲ | thephyber 3 days ago | parent | next [-] | | Why did you interpret your parent as is they were serious about putting nuclear power in every device? It was extremely clear to me that it was a comment to show the stupidity of the admin insisting that energy density was the right/only heuristic for evaluating which fuel sources to use/support. | |
| ▲ | jijijijij 3 days ago | parent | prev | next [-] | | Joking aside, I think small nuclear power sources tend to use much, much more problematic stuff than enriched uranium. Stuff that’s producing enough thermal energy through natural decay, rather than criticality in a reactor. You know, the Mars rover‘s pictures are censored in some areas… that’s where the radioisotope batteries are located. https://en.wikipedia.org/wiki/Atomic_battery Proper reactors are impractical scaled down, as far as I know. Inside a large submarine or aircraft carrier is probably the smallest practical scale for a reactor and I bet there is a ton of trade-offs. | | |

The Curiosity and Perserverance rovers each have one MMRTG (multimission radiothermal generator), and I've never seen a picture of the rover where it is censored, and its actually explicitly called out and shown and drawn attention to in lots of NASA publicity stuff. https://share.google/cqF7eqAJtLH52ALtN https://mars.nasa.gov/internal_resources/788/ | | |

| ▲ | DoctorOetker 3 days ago | parent | prev [-] | | Why would those nuclear "batteries" be censored from Mars rover imagery? To prevent bad actors from acquiring the stuff for a dirty B? | | |
| ▲ | jijijijij 2 days ago | parent [-] | | Yeah, the Mars Liberation Front may use it to attack City 1! It‘s the battery tech, which is classified military stuff. I presume it’s a thing you put in submarine detectors deep in the ocean, or compact spy satellites. But indeed, it’s the type of radioisotope that’s dangerous to just be around, where minuscule amounts could fuck up the whole village. But terrorists would probably rather get their hands on emitters from the medical field than fly to mars. |

The problem is when state actor, potentially, can fund applications for patents and act as a bad actor in the future. Application costs tens thousands of dollars. I actually came across this a few days ago here: https://news.ycombinator.com/item?id=44911423. Prusa, the creator of 3D printers, mentioned that Chinese companies are filing patents on parts he and his team originally released as open source. Just another clear example of how, for some reason, we in the West keep tolerating if not indirectly supporting this kind of behavior. | | |

Live by the sword, die by the sword. It is the West that first turned patents into the weapon for big corps to fuck the rest of the world. Well now they're tasting it themselves | | |
| ▲ | hsuduebc2 3 days ago | parent | next [-] | | Can't really argue with that. I basically expect similar behavior to patent trolls in Europe and the US. And because of the Western sense of untouchability and the illusion of their own importance, they’ll allow themselves to be at least partially paralyzed by a flood of lawsuits. This isn’t about protecting knowhow or actually producing anything, but about generating as much legal and financial friction as possible. The difference is that in China it can be semi-state-backed or at least tolerated, so it’s not just a bizarre parasitic business model like in the West but also a geopolitical tactic. | | |

This has harmed open source in the past, such as the multi-decade, recurring issue where folk have the license to make use of the source code, but not the associated trademarks. 1. As evidence, I offer the great mobile patent wars of the 2010's, which played out similarly across multiple countries the suits were filed, except the home-countries where the scales were the scales were thumbed. |

That's clearly complete bullshit because for most places where someone wants to build a solar or wind project the alternative if the solar or wind plant is not approved is not a coal, gas, or nuclear plant. The alternative is no plant. | |
| ▲ | actuallyalys 4 days ago | parent | prev | next [-] | | As far as I can tell, coal is middle of the pack in terms of energy efficiency [0] and less than half of the energy is captured as electricity, which doesn’t seem particularly incredible in relative or absolute terms. Although comparing fossil fuel efficiency to renewable energy efficiency is a bit odd in one sense because while you’re technically wasting energy with renewables, there will always be more tomorrow, at least on human time scales.

| ▲ | breakyerself 4 days ago | parent | prev | next [-] | | When it comes to energy the efficiency of a generation system is pretty much meaningless metric. Price per kilowatt hour is what rules the roost. Renewables particularly solar have become the cheapest form of electricity in history. This is driving demand for storage which is driving exponential cost reductions in that field as well. Grid scale renewable + storage installations are now becoming competitive with natural gas. Coal is an obsolete energy source. That people in this administration are trying to weelend at Bernie's this corpse of an industry gives me serious doubts about the praise you lap on them. | |

| ▲ | pstuart 4 days ago | parent | prev [-] | | The last shutdown of a reactor in CA was 2013 -- https://www.eia.gov/nuclear/reactors/shutdown/
Diablo Canyon got a reprieve and has 5 more years to go. Dam removals have multiple factors behind them, from pure economics (cheaper to remove than repair) to environmental -- restoring fisheries: https://en.wikipedia.org/wiki/List_of_dam_removals_in_Califo... We need all the non-carbon power we can get, and it's a shame to remove existing power sources but as electric power is eminently fungible, that loss can be mitigated with other sources. Meanwhile, efforts to modernize the US electric grid have been stalled by Red states that are ideologically opposed to renewable power. There's plenty of potential power to be generated that is hamstrung by that resistance (pun intended). | | |
| ▲ | dghlsakjg 3 days ago | parent | next [-] | | The other thing that people forget is that dams, in almost all cases, have a finite lifespan. Both the engineering and (mostly) the silt buildup mean that every dam eventually has to come down or otherwise be involved in a massive infrastructure project rivaling the cost and complexity of building a new dam. | | |
| ▲ | peepeepoopoo140 3 days ago | parent [-] | | Silt buildup is a trope that often gets repeated as a reason for tearing down dams, but it has no effect on power output. Generating capacity is determined by vertical pressure head, i.e. how far the water drops as it passes the dam, and not by how much water is held by the reservoir. It's factually incorrect to say that silt buildup causes a decrease in generating capacity. | | |
| ▲ | eszed 3 days ago | parent [-] | | No expertise in the field, but that makes sense as far as momentary output is concerned. The amount of power generated over a period of time, however, would be entirely by the quantity of water stored behind the dam. At some point it would no longer be economically worthwhile to keep it online. |
