Great by the same logic you should use a commercial reactor over a naval reactor, you should also just use a different power source over nuclear.

If nuclear isn't subsidized by military uses its energy negative when you factor in mining, enrichment, and operation.

>The US has a pretty squeaky clean record when it comes to nuclear safety and storage protocols.

One single nuclear site is consuming 10% of the DoE's budget, and its still leaking. https://www.tri-cityherald.com/news/local/hanford/article228...

Is there an analog for regenerative braking in the flying EV world?

Emissions free uranium mining. Emissions free uranium enrichment. Emissions free refueling.

Where are they?

I'll say it, that user reguritates rhetoric and talking points that happen to be aligned with a multi-billion lobbying industry, but they're always packaged in social media comment sized appealing package.

Very few on HN actually work in the energy industry and so anything that "sounds about right" gets accepted if the person says it confidently. Unlike anything related to computer languages, where there are people who also know the topic techncially to debate.

It's a case of "those who speak do not know, those who know do not speak" because to do the topic justice would be a longer comment than anyone wants to read, and it cbmuser's ignorant comment is sure to be at the top.

Recently the author of "Solar Power Finance Without the Jargon" Jenny Chase was on the Energy Transition Show podcast [0] discussing the growth of solar. The discussion got into some of the technical reasons solar was able to grow as it did; while the analysts were assuming solar was barely affordable with the subsidies, the industry was actually using the subsidies to develop low cost manufacturing processses, springboarding off technology from modern semiconductor manufacturing. A comical moment in that interview, on the same topic as this tweet, was that not only did IEA and other agencies and analyists under-estimate solar, the best estimate (which was still short by half) was from Greenpeace just using a simple compound growth model.

I can promise you the energy industry knows about both CapEx and OpEx and has incredibly in depth models on them for all relevant energy technologies.

And on the topic, I can also promise you that they do in fact know about the concept of capacity factor and that the sun doesn't always shine and the wind doesn't always blow.

And on the topic of France, their reactors oveheat the river they use for cooling and have to shutdown. And just as you claim you can't soley consider the cost of a plant, you can't solely consider the smokestack emissions of a plant without consider the mining, enrichment, handling, and disposal of nuclear.

Germany has a large CO2 output because they have a large manufacturing industry, and for policy reasons technically decoupled from their investment in solar, they also maintain production capacity of a dirty type of coal as power source because they have it in abundance within their own borders, its a security interest.

If you think your armchair analysis has outsmarted the energy industry then go ahead and invest in fossil and nuclear i guess.

Aren't those weird submissions with no comments that show up on here ads? Actually, the last one I saw was for "Substack is hiring talented engineers to redefine the way people read and write things on the internet"

This and sibling comments make good points about improvements it has made. I edited my comment to be less universally judgemental.

My experience is based on a pretty generic unknown low drama instance, that doesn't really block or get blocked, instead relying on users to mute/block/instance block themselves per-account. So initially I saw a lot of ugly things, the usual culture war topics discussed without nuance or compassion, bots and spam, etc.

The Fediverse is an interesting social experiment testing the hypothesis of whether the ad revenue/profit motive of twitter, and the subsequent algorithms that maximize engagement, are the primary source of toxicity and other negative qualities of social media that have been documented recently (social dilemma et al)

Interestingly, the* (see edit) Fediverse data point seems to show that really none of Twitter's problems are solved when its the user's paying and admining the servers themselves.

EDIT: only my conclusion based on personal experience and expectations, encourage anyone to look for themselves

DOWNVOTED FOR TRUTH

Fracking profitability is going down because they aren't able to operate at as high of a capacity factor, because their operational costs aren't as low as renewables.

Don’t forget the diesel, petrol, and propane. The dirty secret of most “off grid”.

I like the part where the fossil fuel industry gets bullied around by the uber powerful environmental groups.

Its funny because besides being the scapegoat for every failure of the fossil fuel/nuke industry, these environmental groups seem to lose every other battle they care about.

How much does it cost to handle and transport these tiny pellets? How much energy goes into the materials needed to manufacture the containments? How much energy goes into mining and refining the ore and bringing it to the reactor?

Detecting radiation isn't the hard (or expensive) part https://www.tri-cityherald.com/news/local/hanford/article225...

Its not nuclear vs oil and gas. Renewables are an alternative with lower cost and lower waste.

A good safety history is a measure of what happened, not what could happen.

Its already Here and its not necessarily industrial scale either its called EPSCrete [1] Yep no need to transport your styrofoam to a recycler and buy back some insulation product when you can make it yourself [2]

is taht why you just repost the same comment on HN over and over again hyping tesla products? Instead of penalizing change, why not encourage it? When you work from home, you don't put anywhere near the carbon into the atmosphere that you would commuting. You also spend a lot less on lunch, and you don't need to put your children into state-run schools that are really there to function as daycare centers as much as they are to educate. If all of that office space in downtown areas stays dark, and the zoning laws are altered or removed, it can be redeveloped into housing that's actually affordable.

We really are running into a wall on the methane crisis, and we we simply don't have the time to integrate these changes at a slower pace.

Let's focus on changing our regulations that prohibit building neighborhoods for pedestrians. Let's work on getting homes with solar roofs and big batteries. Let's get drone delivery everywhere. Let's electrify the transport system with electric cars, electric trucks, eVTOL aircraft. Let's tunnel underneath and between cities and connect them with hyperloops. Let's connect people in rural areas with low-cost, low-latency satellite internet access.

Doing these things will directly provide a great number of jobs for a great number of people. It will make a great number of new jobs possible. It will improve the natural environment. I think this is a much more positive direction to take than to try to slow things down.

This was Target not Walmart and I say that not to nitpick but rather highlight that arguably Walmart is somewhat an upper tier tech company.

If this is what Target does in 2012, Amazon in 2020 not only inserts plausible deniability to optimize for lack-of-creepiness factor. They're probably running AI bots on forums and social media injecting seamless product placement in commentary you see in your browser.

There was a Toyota and Tesla partnership in 2010, producing a small number of RAV4 EVs, combining Tesla's battery pack and electric drivetain with Toyota's chassis.

I haven't found many details outside of wikipedia, not sure the nature of the partnership. If it was about Toyota getting tax credits, Tesla testing an EV drivetrain without having to engineer an entire vehicle platform, or something else.

Small scale solutions would only create jobs for individuals and small enterprise, not corporate profits. Alternatives to consumerism is NOT welcome on hacker news.

The first one.

“Without backdoors” wow, shots fired at Moxie “federation won’t work” Marlinspike’s secure honeypot Signal.

Heh, my used chevrolet EV came with the remainder of 100,000 mile 5 year warranty.

Or do your homework and find that it’s actually far worse than pro-nuclear propagandists constantly claim. Huge increases in rates of multiple forms of cancer near nuclear sites, while the rest of the country is seeing decreases - but not attributed to nuclear. Huge environmental problems and costs pawned off on the US dept of energy and taxpayers, but not attributed to nuclear. Assassinated whistleblowers.

Nuclear industry is a textbook example of regulatory capture. If the renewable guys were anywhere near as good we’d see 0 deaths from solar and wind. “The solar panel didn’t kill him, it was gravity and a slippery ladder”

TLDW: i think anonymity is a huge curse i think if we can do away with anonymity then we can begin to rebuild democracy and of course ultimately it comes down to all of us ultimately we need to learn to be responsible not to insult not to propagandize and i think that will only come just as we look at each other as physical people in a place like this that will only be that will only eventually be realized if we can do away with anonymity so a new social contract new ways of reinventing democracy through analog and a more creative and responsible regulatory attitude towards um to to big social media and internet companies
