What unions are involved in ethanol? That's primarily the corn farmer/big ag corps' interest.

That’s a good plan. I’ve been using a battery mower for a couple years now and don’t miss gas at all. It’s nice having a mower that just works. I hardly mind mowing at all now.

I don't know why you have so much trouble with Bosh, they're up there with other well known brands such as Sorny, Panasomnic and Magnetbox.

On the other hand I have a cordless Bosch drill/driver set I bought refurb, they've held up to years of neglect and (not pro) use. Maybe give them a try next time?

Edit: jokes aside, that's good information. Fwiw I had to babysit a little tube for an hour+ to drain a Samsung washer to get at the drain filter. I wish I could have used a shop vac to speed that up.

A local machine shop could probably build up the steel in the worn keyway in the shaft with a welder and cut a new keyway for a good deal less than the new part cost.

Yes. They didn't just stop testing for flu when someone shows up with influenza-like illness (i.e. flu, covid). Maybe in some places where medical systems were already struggling in normal times, but not in developed nations certainly.

Blindly applying your advice (which was offered without qualification - so that's how I'll respond) opens the door for all sorts of concern trolling and contextless talking point repetition. That often-paid messaging serves a purpose to drown out nuanced and insightful debate with low-information content to defend a status quo or to run interference for an unpopular position to gather support without significant rhetorical challenge. We see that plenty online and in broadcast media, and is like that Buckley is described as doing but these days often more rote and mindless.

Allowing that sort of thing to mix with good debate waters down discussion. It turns people off to opposing viewpoints too, since they're so inundated with rhetorical noise that they need to dismiss most rhetoric out of hand due to the poor SNR. I don't think your position is a very good one.

You should maybe take this as a lesson to not try to speak authoritatively about things you are ignorant about. If you don't know, offer speculation sure but statements like 'almost certainly' and arguing all up and down the thread from a position of ignorance rightly earn you downvotes.

Some of that cow pasture/range land used to be better land, and has been degraded by bad farming techniques and/or overgrazing. The area around Pipe Springs, Utah for example, was significantly more lush 150 years ago, and now it's scrub land. It would be a mistake to think of land as static and only fit for a limited set of purposes, and to therefore exploit it without concern for what it is or could turn into (for better or worse).

We're also causing top soil to erode and blow away in much of the corn belt [0]. That productivity has a cost and shouldn't be assumed.

edit: I don't think we disagree, much. I'll leave the above for reference.

NOx/SOx emissions specifically. People repeat that statistic a lot and mix it up between noxious particulate emissions and climate-changing CO2 emissions. To be clear, cars emit far more CO2 than the largest container ships.

I think you're underselling moorlands here. Trees can be planted on moors, and other even more carbon-sinking activity too: "It’s worth remembering that the peatlands of the UK store more carbon than the woodlands of the UK, France and Germany combined!" [0]

That's equal to or less than what I pay in the US. Seems to me the Canadian system doesn't drive up costs that much.

Your source seems to be low by about 2 orders of magnitude on the energy density of lithium. They assume ~100% of a battery is made of lithium. There are only 200-300g of lithium metal per kwh in a lithium ion battery[0,1], or 12-18MJ per kg.

On a side note, that graph is almost unreadable to me. What, are we paying by the pixel now? The legend is barely there.

Prior to the industrial revolution the CO2 in the atmosphere was significantly less than today, around or under 250 ppm, so a bit of methane wasn't a problem. Now even the same amount of methane when added to the 410 or so ppm CO2 we have today and it becomes a problem. Of we can reduce atmospheric methane it takes off a bit of the pressure on us to reduce CO2 levels.

STC rating, or as you point out maybe a more expansive take on noise attenuation, is going to be high on my requirements list next time I look at an apartment. I think that and general sanitation (i.e lack of rats, roaches, bedbugs, mold) are the things that have the most acute effect on livability. And not having to walk on tiptoes is nice too. Unfortunately new construction is all about making a building cheaply, but soundproofing is almost impossible to do after the fact unless you want to gut a place.

Admittedly I came at the GP harder than I could have, but it's so easy to write off large diverse institutions as "fucking bullshit" and poison a discussion before it even starts that I think it was warranted (that was the top comment at the time). One of the things about bullying is it's so easy to walk around tossing bombs (metaphorically) that sometimes people don't realize what they're doing until one of those bombs explodes a little closer than usual.

The OP didn't critique anything. Simply decrying an entire institution isn't a critique, it's a denouncement. A critique involves analysis.

Also, if I violated HN guidelines, so have you, by calling me out in turn.

Don’t you see that you’re doing what the article describes, right now? Your shallow analysis and careless invective, somehow pointing the finger at school systems for something that is largely a result of human nature, is bullying. You’re throwing school systems under the bus for internet points.

Could schools handle bullying better? Probably. But your call for “questioning” is not at all constructive or actionable. To me you demonstrate only that what the article describes works just as well on hn as it does in schools. Dunking on easy targets for social standing.

I'm with you on this. I recently tried out a keyboard with Cherry MX switches and was taken by surprise by how wobbly they were. I assumed they would be less wobbly than my old keyboard. It really ruined whatever tactile gain there was to be had. Sure maybe that revealed some problem with my typing technique, but I can't picture myself growing to like such a wobbly key.

Baseload + peakers is one concept that allows a grid to meet demand. But it's not the only way - decorrelated intermittent generation + peakers could work too. But what doesn't work well so well is baseload + intermittent generation. If you must have baseload (i.e. nuclear) as the foundation of the grid, intermittent renewables (solar/wind) aren't going to have much of a place because you need dispatchable power generation to fill in the demand peaks.

As long as we need peakers or other dispatchable powers supply, I like solar and wind over nuclear to provide the main quantity of generation vs nuclear. I don't see nuclear catching up to renewables on cost terms at this point.

I would hazard a guess that people who buy lottery tickets are much less likely to buy insurance than those who don't. I think some similar psychological mechanisms may be at play, but not in the way you are suggesting where they overestimate small probabilities across the board. I suspect it has more to do with discounting odds that are against them.

But I wouldn't bet on it.

>In the US all land is in a county

Not 100% true - there are independent cities in some states. But this is just a nitpick.

If you consider comments and posts from anyone on Twitter or Reddit who claims to support one side or the other, it would seem you have a point.

But if you look only at what the elected officials from the two sides say, it's clear that there is a world of difference. That's where the difference lies: one side doesn't tolerate anything like the level of extremism or violent rhetoric from the people they elect compared to the other.

There are people who truly believe that widening roads causes more cars to drive on them and fails to relieve congestion. Imagine that!

Except, that phenomenon is well-supported by research. Perhaps the situation you describe isn't so impossible as you suppose?

That study is an extremely weak support to the claim that this virus can't spread asymptomatically - it's nearly useless for that purpose. They only studied a small number of people at the very tail end of the infection who showed that they had some evidence of virus in them. They did not look at whether those patients actually had an active infection - they could have simply been detecting remnants of dead virus in their systems. They certainly didn't look at all at people in the incubation stage pre-symptoms.

Free market principles fail for healthcare for reasons entirely unrelated to those things, as has been pointed out up-thread. You're advocating for regulations to be eliminated as if that would fix unrelated problems. Do you care if healthcare is improved, or do you just want to see free-market-style reforms for their own sake?

Don't discount the energy cost of air infrastructure in this comparison though. Airports have a huge amount of tarmac that must be built and maintained, there's the jet fuel production/transportation infrastructure, and of course building the planes themselves. Rail may have the larger overhead, but air has some too.

Wouldn't a heat exchanger top out at equalizing the inward and outward bound air at 20F in this case?

"Apple’s effective U.S. federal income tax rate was just 7.3% in 2011. Apple claimed its tax rate in 2011 was 24.2%, one-third less than the official tax rate of 35%. But the Senate subcommittee found its rate was no more than 20.1%, allowing "Apple to claim credit for $3 billion of deferred taxes on overseas income that are not owed until the profits are brought back to the United States. Since Apple has said that is not likely to happen, its effective tax rate in 2011 was just 7.3% – $2.5 billion in taxes actually paid against $34.2 billion of income before taxes. [Exhibit 1a, pp. 38-39]"[0]

150 years ago there was no energy grid anywhere in the world. We've come a long way since then. You seem really confident that a renewable grid will never happen. Do you have credible projections on storage and deployment costs that indicate asymptotic bounds on cost that are above the cost of similar projections for comparable nuclear?
