I just read the US section and it seems to contradict what you just stated above. If you use incendiary tennis balls it qualifies as a "destructive device" but then it's not really a potato cannon anymore.

It also says if you use compressed air that completely disqualifies it from "destructive device" potential classification in the eyes of the law.

Pipelines solve this problem quite neatly. The transport cost of a pipeline is very small compared to the fuel transported.

Interestingly pipelines can have near perfect fuel efficiency (though few do) since it's possible to run the pumps with electricity. That means if the electricity that ran the pumps came from wind or solar no fuel was burned to move the product.

At this point in time the only other thing that might be able to work that way is electrified freight trains. I don't believe there are any here in the US, at least not significant distances.

Ah I see. That analysis works if you neglect the free body diagram of the system. I agree with your analysis if one larger terminal were analogous to two smaller ones. But it is not.

When a bolt applies clamp force it does so to every thing in between the bolt head and the anchoring threads. All of the force is transmitted along the bolt shaft from the mating threads to the head of the bolt and then back down whatever is in between the bolt head and the mating threads.

If this were not the case no fasteners would work. The only exception is when you have multiple mating threaded regions, rust, etc.

If you put one washer in between the bolt head and the threads obviously it must feel the full force of the clamping, or else some force went missing.

If you put two washers in between they're both still trapped in this identical clamp force situation.

This can be extended by induction about as far as you'd like. Certainly 2,3,5,10 washers. Even to 100. Eventually gravity and other things start to creep in at much, much larger scales. If you wanted to clamp 1 million washers this simple analysis would fall apart of course.

I don't follow how stacking two terminals cuts the clamping force in half.

If a screw provides 10lbs of clamp force, the equal and opposite reaction is that the thing it is screwed into must resist with 10lbs.

If you put one terminal in between it must transmit all 10lbs through itself or else the forces don't balance out and something must be accelerating.

If you then stack another one in there all the force must be transmitted through it also. So the screw clamps with 10lbs of force and both terminals feel 10lbs of clamp force.

I just can't figure out where you got the idea of "it cuts the clamp force in half" but I'm interested to hear.

Is that nameplate or actual usable solar? In Texas or Spain the solar capacity factor is about 0.2, in Germany it's probably 0.15 or less.

So if it's nameplate equivalent but with nuclear capacity factor of 0.9 or more you'd have to 6x the solar to produce the same amount of energy to the grid over a year.

Environmentalism suffers from the same "purity test" mindset as other things these days. Better than incumbent alternatives is nowhere near good enough. It has to be blameless now and forever.

It's really too bad because perfect often is the enemy of good. And when nothing is good enough to be perfect people burn fossil fuels instead and get on with their lives.

It's an ugly truth but it's true.

Yeah I understand the sentiment there. Now fast forward a few years to when a new government is elected that perhaps doesn't reflect your sensibilities.

Now they can use this apparatus to promote their version of the truth (might actually be false) and to suppress yours (which might actually be true).

What do you do now? How do you even mount a criticism of this entity? They'll likely work very hard to suppress your criticism and label you a misinformer.

The COVID vaccines have saved many lives. They've also caused some adverse reactions in some folks.

Should people be allowed to discuss this? Is this reckless or responsible? Why? What happens if the science changes? Who ensures that the folks in charge stay current?

Don't get just TSH checked, get a full thyroid panel. You can have normal TSH but still be low on free T3 and feel bad as a result.

That's weird, I thought I was a customer not an investment. In general of course, with HP the shenanigans have been obvious for a while.

It's nice to see people saying what they actually believe out loud. Refreshing.

There probably is one out there somewhere. But there are many that ferment to ethanol and those are looked after and can probably out compete the methanol in most situations.

Honestly if you're just trying to store energy going to ethanol is fine too. It'll burn just fine provided you've dehydrated it enough.

Craigslist or Facebook marketplace. Some fool like me would be happy for a used speed queen to fix and keep forever. It's 20 items down my household Todo list but will never get done since my 20 year old top loader just keeps working.

Jump on eBay looking for the soap dispenser for that model of dishwasher. You might find a whole replacement dispenser for that price.

The "food" in America has never been grown with more fertilizer. It's probably missing all kinds of stuff that would be there otherwise.

You can buy and eat only organic and that might help. Even that's no guarantee of nutrient quantity though.

Same here. The problem is that there's no consensus on what voltages. I might prefer 48v for lower losses but you might want 24v since it's "safer" and my neighbor might want 192v since he's already an electrician.

People also smoke and drink and catch diseases.

They might say there's more to life than trying to live forever.

You can always continue to hold until you're into an emergency and then declare it. I mean it'll probably trash your career but it might impact the ATC too. Hooray?

Here is an article detailing a substantial set of changes made to the election process just before 2020. These might have all been perfectly legal things to do but when you make enough changes all at once some people start to wonder.

I love this. I wish we got more of this kind of thinking in medicine.

I'm guessing it's this at work: https://en.m.wikipedia.org/wiki/Jevons_paradox

Yeah that's all fair.

But the problem is that since as the safety improves so does how people use it. More safe means we can use more since it's not as scary.

It's so safe we can spray it on the wheat two weeks before harvest to make sure it's good and dry. Hopefully it doesn't rain!

Big company threatens to spend $100 million on the lawsuit to make sure they win. By outspending you they exhaust your funds and win by default. Then you go doubly bankrupt when you have to pay their legal bills.

I don't think you understand what geostationary orbit is. They all have to be going the same direction (with the Earth's rotation) or else it isn't stationary (not moving) over the geo (earth).

As a result I think you're misunderstanding what the orbital dynamics would be.

I used to think that the generators were running at the bank call center 1/4 mile away. I only heard it when it was very quiet, any noise at all and the low droning disappeared.

I took more vitamins during the early days of the pandemic and magically the generators stopped running.

If it works great at 10c and OK at 0c and just a little bit at -10c but extracts no useful heat at -20c and your local weather has lots of time below 0c, then no amount of low temp floor heating will help.

A ~50ft trailer is pretty common, and it should be about 8ft wide and 8ft tall. So 24ft * 50ft is more than 1000sqft and it's approx 10sqft to the sqm.

Of course your best case scenario is only about 400sqft illuminated. Insolation tops out at 100w/sqft and the max efficiency of commercial panels is maybe 22-24%. Doing the math there you get something like 7-10kw which is nowhere near enough to push one of these down the highway.

A normal semi gets maybe 6-8mpg on diesel which means burning 8gal to go 60mi in 1hr. You get about 10hp/gal/hr out of a diesel so that means it takes something like 80hp or 60kw to drive a truck down the road.

It's more then enough to run the climate control, lights, and other cab loads and slow battery drain just a bit. But you'd have to leave the truck to charge for a week in order to drive for a day.

I don't just want it to be safer than me, I want it to be shockingly safer. If self driving cars are safer than an average driver that's great. But the cars need to be 10x as good as an average driver and 2x as good as a 99th percentile driver before the objections start to fade.

Office workers didn't like the commute for 100 years and employers didn't do anything about it.

Its pitched as just for irrigation, not drinking water. Not nearly as dangerous as a result.

I had symptoms of low stomach acid for a while also.

Six months into COVID I hadn't experienced anything at all on what would have been 1-2 monthly flare ups. Once I had the realization I put it all together.

When COVID hit I had restarted taking a multivitamin and some extra iodine (which is involved in stomach acid production, as it turns out). I had thought my diet was pretty healthy, but as it turns out there was something I wasn't getting enough of. I still don't know what. But I keep up with it and I don't have symptoms.
