It's a test pad at Kinloss Barracks, formerly RAF Kinloss and was home of the now defunct Nimrod fleet, it is due to launch properly from Sutherland when the launchpad there is completed.

Helion a lot more interesting due to not needing Tritium
Doesn't need a lithium breeding blanket either or beryllium as a neutron absorber. Uses basically a ionised plasma as a means of producing energy by varying the magnetic field and the expansion and contraction of the plasma with respect to the high energy magnets.
If only humanity could make metallic hydrogen it would get us to the stars and power all vehicles on the planet as well. Too bad it can reach 7000Kelvin when ignited and will destroy most of our engineered materials. Other option is fusion detonation engine, but again we don't have the technology to power a magnetic compressing fusion detonation engine.

if it's fart dry so that they burn on their own, you have a problem with your crops anyway. And look how small the crops are, there is a lot of space between individual leaves. Idk if it's also intended to repeat the process when plants are much taller. Then it could be an issue (with plants touching each other, and having more burning mass)
it kills weed, not bugs btw (although if its a large bug, it might be missidentified as weed?)

it is probably to eliminate weed threats on juvenile/young plants to give them time to get established (and to stop weeds using up moisture), usually once they grow to a decent height it smothers out the weeds, that is why in a situation where chemicals are used to kill weeds it is only done until the plants are established, afterwards it is not required.

Can't we somehow harvest lightning and store it in a battery or somewhere?
astral peak
would be incredibly difficult since most of the energy that reaches the ground is heat
which would damage most things
similarly the amount of time it would be trying to force the energy into the battery is beyond our technological capabilities at the moment
drifting bluff
The thing kind of basically is that when the lightning strucks, it's already a short circuit. You would need to harvest the potential energy off before the potential is too great. Discharge the clouds until it's too much.
Just to thinking about the basics.
astral peak
you are asking for a static electricity discharge from a cloud that can be harvested within the split second that it takes
not possible with current capabilities
drifting bluff
Yep. Quick discharge is hard to harvest. Better would be to harvest the potential build up until it's too much. Because actual lightning harvest is like trying to harvest energy from a light bulb that's on couple milliseconds.
Imaging something like 10km tall "wire" reaching top clouds to earth sucking up the build up of the potential. Just don't overload the system or 😅
So not really "possible"

If you truly wanna "learn everything about it", I really suggest you build a good foundation of how electricity works so that you build on that knowledge
On the cheaper side on things, you can get trial versions of simulation software to mess around with.
I highly suggest you find a project to give a purpose to your learning. There's tons of cool things you can do for very cheap once you get one microcontroller, a breadboard and components

solar or nuclear seems to be the safest
forgetting about dams
The way it all works is, if there's a great advancement in power generation, the various governments and multi government organizations will go at a great length to make sure they have it and prevent it from arriving to the consumer. You can't control people if they can generate their own power. We'll see nuclear fusion at some point in the future, but never at a point where you can become independent.
This is the same thing with medicine, the cures and methods to curing serious diseases are controlled by them as well. Before, you'd see researchers dying in "accidents". What happened a month or two ago, several researches make advancements regarding cancers and HPV and nothing happened to them. Why? Its because the US left the market, they have very heinous organizations who seek to prevent others from beating them. They care more about money than saving lives.

@peak prism taxonomic ranking can be confusing at times and I'm by no means an expert, but could you elaborate on the post you made about canines? Canine isn't a formal taxonomic rank as far as I can tell, the closest taxon I would use to describe that would be caninae which is way above the species rank (a family of the carnivora order). Also, what did you mean by "sub-species genus" as genus is a rank above species. As I mentioned, dog breeds are not a sub-species of dogs(canis lupus familiaris), but dogs are a sub-species of wolves (canis lupus).
marsh kraken
Indeed "sub-species genus" does not exist. The correct way is Genus > Species >Sub-species. A good source to get classification, is as often, the ncbi website. https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?mode=Undef&id=9611&lvl=3&keep=1&srchmode=1&unlock

I doubt that Arma is suitable for this case, since it requires too much managing and too many people to handle.

Bungie (the company behind the original Halos and Destiny) has been doing some neat predictions with their Destiny series. Astrologists have apparently discovered an object approaching planets at high speed and slowing down as it got closer, the Traveler in Destiny did the same thing before arriving at Earth. The Shadowkeep DLC from last year (spoilers ahead for Destiny fans who don't know) showed something inside the moon that shouldn't be there ||(a Triangle ship which is a physical manifestation of the main bad guy of the game).|| Supposedly, something IRL was found inside the moon that shouldn't be there.

But with regards to that question @delicate hornet, I feel its due to culture or logistics if it costs too much to change measurements on instruments and such.
I suppose it'd kind of be like instantly making America totally use metric instead of just its military, they'd have to adapt quite a lot due to not being used to it and most of their products relying on imperial.
delicate hornet
so you are saying the imperial system advantage is more of a subjective aspect to you?
broken horizon
Yeah exactly.
And that I'm mostly good at converting those measurements to metric so its not too difficult.

I mean, I don't bash people for using what fits them better and especially what they have been taught - really, I don't
I bash countries/groups for enforcing an obsolete and not instinctive way of measurement

But either way, its up to you and I just meant to meme you lol

But funny enough though.. Mass in Arma technically isn't consistent with KG nor LBS.

speed sometimes is in km/h, sometimes in m/s
broken horizon
At least to ACE since Arma's Katiba rifle is 100 mass while its potentially 3.67kg / 8.10lbs.
True haha
delicate hornet
now we are entering Arma inconsistency, and we would need a full channel just for that 😛
broken horizon
Yes xd
But what I've seen though, projectiles tend to be measured in m/s while speed of other things is generally measured in km/h unless something's SUPER slow.
*unless
measures snail speed at microns / second
delicate hornet
~2m/h iirc 😄
broken horizon
Oof lol
But yeah, I think that'd be 200,000 microns per hour so that divided by 60 would be a bit more than 30,000 per second.

@radiant osprey
(if you could travel at 250.000km/h)
another thing to think about, there's no telescope that can look that far and focus on a single object, no mirror strong enough to reflect an image from earth
but, you'd be looking at a younger you (in theory)
20y younger
lunar dragon
@radiant osprey You'll have to wait for 10 years for the light to first able to reach the mirror. And wait I don't think your image would actually get that far intact if not nothing thanks to Earth's atmosphere it'll get refracted and diffused heavily. Even if you ignore that part, as you said the mirror is 10 light years away; it'll take you another 10yr to get it back, this is considering the reflection doesn't have any interference, cause getting a such a tiny image intact would be super hard if not next to impossible
theoretically you can
but since it's a tiny image and our telescope is in motion (it's on earth) it'll be hard to get the reflection as you would have to be super precise about your place of observation, angle, etc

If anyone wants to read a good science book I can recommend https://josef-gassner.de/shop/können-wir-die-welt-verstehen-meilensteine-der-physik-von-aristoteles-zur-stringtheorie-detail.html (German language only sadly)
The theoretical astrophysicist Josef M. Gaßner and the experimental physicist Jörn Müller guide you through the great theories of physics in a generally understandable and vivid way. Their presentation bridges the gap between popular science books and specialist publications, as they also offer the language of mathematics as an accompaniment for a deeper understanding, while at the same time proceeding with a sense of intuition.
The reading resembles a mountain hike, climbing up the hills of classical mechanics and special relativity to the first vantage points of general relativity and quantum mechanics. From the main crest of the quantum field theories, the Standard Model including the Higgs mechanism, we climb the summit high to the gauge theory, the quantum loop theory, supersymmetry and string theories.
You are invited to enjoy the magnificent views with us!

Let's just hope they figure out how to produce all the electric energy for their E-Cars until then.
onshore & offshore wind, tidal, solar mix with storage batteries and whatever nuclear plants the uk has left that arent crumbling to pieces.
for example, the place where i live has been powered entirely by renewables for a decade.
we're currently waiting on Ofgem to authorise subsea installation of another interconnector so we can export more.
fwiw we also produce our own hydrogen, which is used to heat schools, power docked ferries overnight in addition to local authority vehicles.
the only way they will get a large swing to BEV vehicles is by reducing the cost of them, currently most BEV's are £25k+ to purchase, they need to mass produce them to bring the costs down.

When a cable snaps you definitely dont want to be anywhere within the cable snapping distance. And then there is the chance of something flying loose and going off like a sling shot...
those things can cleave you in two...
faint leaf
Exactly, it was also found that the cables were fairly degraded across their whole length, and while they were most likely to fail at the point where they connected to each anchoring tower, they could have failed at any point along their length in theory. It was just the uncertainty of it all. Arecibo was incredibly valuable, but not worth a human life.

the whole situation boils down to a complete lack of financing towards it (maintenance/preventative-maintenance/upgrades) and the science it was doing, it's a real shame the world lost such a useful asset.
stuck vortex
When a cable snaps you definitely dont want to be anywhere within the cable snap...
I have been around my fair share of steel cables snapping, it's not pretty and you can work to methods that minimise risk around tensioned cables, but those cables I experienced were much smaller than the Aricebo ones.
The sheer mass of the cables and attached to them at Aricebo would generally prevent movement in any direction but down - due to the 900T apparatus floating in the centre pulling them downwards as witnessed today. (the 500T in my previous post was wrong - https://www.naic.edu/ao/telescope-description)
