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.
I would also add that usually i will be used inside the code block to index locations within whatever data structures need to be accessed. Keeping track of how many times the loop has run has more utility than just making sure something is repeated 10 times.

Most of those are pretty cool, but the watch really let the gimmick compromise the function. Clock faces need to have high contrast for minimizing the time it takes to read the time.
Fermion@feddit.nlto Technology@beehaw.org•Helion eyes Washington site for 2028 fusion reactor build12·2 months agoHelion 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.
In NC at aldi, cage free eggs are $4.50/do. and free range eggs are $5.30/do.
I get that price are regional, but there’s got to be another factor for why the price is double what I pay for pasture raised eggs.

With the water powered jet packs the water isn’t just being accelerated from a standstill. The water is first flowing up with close to the same speed and is redirected down. So the momentum exchange is twice what it would be if the water were stored in tanks with the flyer.
I wonder if you could drill out the pit to a shallow depth and then preheat your extruder and jog filament to fill it in like a hot glue gun. Then trim, sand, and polish it back down.

Fermion@feddit.nlto Asklemmy@lemmy.ml•What's best for the planet? 4 solar panels or 2 bee hives?9·4 months agoThe beehives have a huge prerequisite of making sure there’s enough flowers throughout the year to feed them. So if they come with installing a full rooftop garden, that’s great, otherwise you’d be better off sticking to the panels.
But putting up panels wouldn’t prevent you from also starting container gardening. Pollinating insects are pretty good at making their own homes. What matters more is growing food for them and their larval stages to eat. So if you’re up for it, install the panels, and start filling the gaps with container plants. Just don’t go overboard because soil is too heavy for roofs that aren’t designed for the extra load.
These days that’s true for me as well, but I do miss the old blackboards and chalk.

Jeans are the main item I order online. I don’t need to have a wide variety of pants and I’m ok getting the same thing repeatedly. Shirts vary too much for me. Even the same brand and size label can have drastically differing fits so those are in-person only.
I grew up near a guy with literally dozens of towers on his land. He would get paid to decommission old towers then he’d put them up at his place rather than scrapping them.
The antennas can be a lot more than just through the roof.

Plasma is very short lived. Think on the order of microseconds at atmospheric pressures. So unless there was a massive linear source of power along the whole length, this isn’t plasma.
The visual effects probably have to do with the fact that the sun was very low. I’m guessing the particle size distribution in that line is notably different from the size of particles in the clouds surrounding it, leading to much stronger reflection of evening light.
I am curious as to the meteoroligical explanation for the line though.
