Ground hornets pattern match too. I had a massive nest I had never noticed in an old stump. They hadn’t bothered me despite having walked by numerous times. Then one time I hit the nest with the riding mower. Man that sucked. I’m not outright allergic, but a dozen stings does make me feel sick. After that, anytime I got within 20ft of the nest with the mower they would come out in force.

Then a few years later I had the same thing happen with a raised garden bed. They never bothered me and I didn’t even know they were there, until my weedwacker attacked the entrance of the nest. I had to steer clear of that section of the garden for a few weeks after.

Ground hornets are horrible.

Yeah, black holes in media where they are depicted as a giant space vacuum cleaner is a big pet peave of mine. Unless you get really close, nothing is remarkable about the orbital mechanics of a black hole. The equivalent mass star would have burned you up at a much further distance than the gravity starts to become noticeably wonky.

It’s a shame that writers focus so much on the gravity and neglect accretion disks and astrophysical jets which do extend large distances and are visually stunning as well.

The problem isn’t methane production, it’s excessive soluble proteins producing a thick foam that prevents the methane from being expelled through the esophagus. Any feed produces large amounts of gas in grazing animals. What changes is the animals ability to safely vent the gas.

Sometimes animals escape their enclosures and mis-feed themselves. The couple times I’ve witnessed this were the result of cows helping themselves to a field of alfalfa. Alfalfa is good as a component of a silage mix but is too rich to be consumed fresh on its own. But cows love alfalfa and are good at finding weaknesses in fencing.

Radon should be yellow. You don’t want long term exposure of it in your lungs, but it’s still mostly chemically inert and not a significant immediate danger.

The ridges of the weave in my pants sometimes produces a vibration that is similar frequency and intensity as my phone vibrate. It totally triggers the check the phone reflex even if it happens while my phone is in my hand.

I know you just copied the youtube title, but the title is obnoxiously pretentious.

The issue is the ambuguity in what someone intends when they just say radiation. It is valid to call any electromagnetic wave radiation. However, as for health concerns, what matters is “ionizing radiation.” Microwaves are too low energy to be ionizing, so they don’t match what most people think of when they say radiation with the implication of ionizing.

The stuff that is heavier than water ends up in the river delta, everything else dilutes into the ocean. Once it’s in the ocean, there’s not much humans can do about it. Promoting populations of sea grass and filter feeders like mussels can at least capture pollution in a form that settles to the seabed and improves water quality.

There will be pockets of pollution that persist for a long time, and floodwaters could stir some of that back up, but the above poster is correct. Cleaning up a river can be as simple as stopping the sources of the pollution. A dirty river is dirty because stuff keeps getting added to it. Of course stopping sources of pollution is way easier said than done.

Maybe the non-morons don’t make a point of telling you they have an MBA.

I don’t like this system for two reasons.

The first being that bookshelves should have a restraint system that attaches to the walls. You could probably improvise something, but the video lacks that element.

The second is that the alternating brick pattern is weak for an open faced box. That puts a significant portion of the weight of higher courses on the middle of the span of lower courses. You can see some of the lower levels bowing signicantly. Since the back is rigid, but the front can flex, that will increase the tendency to tilt into the room and makes the tipping hazard worse. Add in an old floor that is concave and you have a significant hazard.

I like the concept, but this needs some changes before it is safe.

Edit: I’ll suggest potential improvements rather than just naysaying. You could make two different width boxes. A full width and something like .8 width. You would stack the boxes alternating full width with partial width. The full width box would need 4 alignment pins and 4 slots. The boxes would stack in line vertically, but due to the alternating widths would still lock adjacent columns together. The important thing is that the vertical walls would be close together rather than landing in the middle of the spans.

Then I would add a cap board that can be bolted into the top boxes and would be used to attach a L bracket to a wall stud. Yes, this decreases portability, but not crushing children is more important than convenience.

I only used it for desktop applications. That’s good to know.

Screen sharing in signal seems to work reasonably well.

Helion is a completely different technology vs tokamaks which is what you’re thinking of. They pulse the plasma to create brief bursts of pressure/heating/fusion. They do already have their seventh prototype machine operational so while we can’t independently verify their claims, it’s probably not all bluster.

I have mixed feelings about their approach. They plan to use a deuterium and helium-3 fuel blend. That has a couple major advantages. Most of the reactions will be aneutronic and the energy is released in the form of highly energetic alpha particles and protons. The lack of a high energy neutron is a huge advantage for safety and longevity of a reactor. High energy neutrons are hard to shield from and they cause most materials to get brittle and weaken. Netrons are not good for personnel to be around and they can leave some materials radiactive making reactor maintenance/disposal costly. The other advantage is that since all the energy is released as kinetic energy in charged particles, they don’t have to try to absorb high energy photons or neutrons into a water blanket to drive a steam turbine. Instead, the kinetic energy results in an electromagnetic pulse that can be harvested by the same magnets that constrict the plasma to begin with.

Sounds amazaing, right? So why doesn’t everyone use this approach? Helium is rare, but Helium-3 is especially rare, making up only about 20 parts per million of helium found in geologic deposits. So simply put, it is currently infeasible to use Helium-3 at scale. Helium-3 can be collected as a byproduct of breeding tritium for use in nuclear warheads. Enough helium-3 is produced for some demonstration reactors, but any real amount of demand will quickly outpace what the DOE produces.

Helion plans on breeding their own Helium-3 in Deuterium-Deuterium reactors they will operate. However D-D reactions are not aneutronic. So all the materials lifespan/shielding/ maintenance nightmares that come with operating a nuclear reactor will still apply. That means operators will have to buy very expensive fuel from Helion indefinitely. Helion doesn’t exactly deny this drawback, but I really dislike how much they gloss over it in their public communications.

Here’s a video tour of their test facilities that explains the basics of their approach. https://youtu.be/_bDXXWQxK38

I’m inclined to think they’ve demonstrated enough results that they are likely to be able to build a working unit quickly, however, that would still be a long way off from creating any sort of sustainable supply chain that would be a viable option for anyone beside datacenters.

PMI specifically only applies when you don’t have a 20% down payment. If your income is consistent and high enough to qualify you don’t really need to wait until you save up a big down payment.
