flow batteries

New, long-lasting flow battery could run for more than a decade with minimum upkeep

Researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a new flow battery that stores energy in organic molecules dissolved in neutral pH water. This new chemistry allows for a non-toxic, non-corrosive battery with an exceptionally long lifetime and offers the potential to significantly decrease the costs of production.

The research, published in ACS Energy Letters, was led by Michael Aziz, the Gene and Tracy Sykes Professor of Materials and Energy Technologies and Roy Gordon, the Thomas Dudley Cabot Professor of Chemistry and Professor of Materials Science.

Energy Tethers 101

Updated (again): 04.28.17

*this post is fueled by angst*

Okay, no, seriously though, it really does make me sad that so many people seemed to have no idea what I was talking about when it comes to connecting things for energy transfer.


So, what even is an energy tether?

I personally use the term “energy tether” to describe this type of energy work, but they could be called anything - energy cords, energy feeds, etc. Basically, it’s a metaphysical connection to allow a direct and continuous flow of energy from a source into a target. And I say target, because it doesn’t need to be an inanimate object - it’s possible to do this with yourself too.

That sounds a little convoluted, Richtor; can you break it down a bit more?

Yes, I know, I’m fancy with my words. You’re creating an energetic line between two things, one thing to be used as a battery, to allow energy to constantly flow from the battery into the second thing, keeping it charged / powered forever.

Are you serious?

Yes.

Why don’t we do this for everything in magic?

Honestly, I don’t know. If you’ve got an understanding of energy work and visualization, it really isn’t even that hard to create one. It can even be done with representational magic if you really wanna go that far, but it’s not that complex when you get down to it. 

I’m assuming it’s just a case of, people don’t think about it like that, or, it wasn’t as widespread a thing as I thought it was.

Can’t we just do this with passive charging, like how we charge things in moonlight?

Yes, but objects only hold a limited amount of energy before they become full; once you’ve used up the energy, you need to recharge it again. Creating an energy tether allows a constant flow of energy, so as it is being used up by your intent or goal, it just refills itself.

To me, passive charging is no guarantee that the energy will stick or be absorbed by the object, and that is also why I prefer things that require focusing on the energy yourself (direct channeling), or this method.

What *can* you use energy tethers for, anyway?

Basically anything you want to keep charged for extended periods of time. Optimal for sigils, any sort of charms - hell, you can even connect thoughtforms / servitors this way. But, seriously, anything you want to keep constantly charged with minimal effort, this is a way to do it.

What can you use for “batteries” or power sources?

Anything that produces an almost endless amount of energy. The sun is the first and most obvious one I think of. You can use anything else that produces a lot of energy, though. If you live near a dam, or those electricity windmills, those would work. Power lines and electric generators are awesome, and a great way to incorporate different feels of energy (and tech magic) into your practice. Space, even; like, the entire damn thing. If it produces energy, it can be tethered.

What do you mean about different feels of energy?

This isn’t specific to tethers - all things that have and produce energy have different “feels” to them. The sun is more hot and energetic than the moon, which is cool and calming. Rose quartz is a bit more gentle than, say, jasper, which is hot and fire-y. Tiger’s eye is more solid and stable than clear quartz, which is fluid and mold-able to almost any intent. 

We all experience feels of energy differently, however; these are just how I “energetically feel” those things.

(You also don’t need to “feel” anything to still do energy work, but that’s like a  whole ‘nother post.)

Can you tether to something that doesn’t have unlimited energy?

Sure, yeah, but you’ll drain it, and then it won’t be fulfilling its purpose anymore.

So, you could use yourself as a power source?

You could, but it’s super draining and I wouldn’t recommend it. That object would constantly be taking your energy away from you, and it could have bad consequences, including physical ones - physical exhaustion is a side effect that can occur when you use too much of your energy, and I see it happen often to people who are not careful about their energy expenditure.

However.

You can create switches for your tethers. As in, you can cinch them, close them off, to stop the flow of energy. Like you can turn on a pipe to get water flowing, then shut it off just as easily - you could create a “modification” for a tether similar in that manner.

Can these energy lines be broken?

Yep, absolutely. You can do it yourself if you no longer want them, someone else could do it if they could sense them, or they can naturally fade over time if you don’t give them proper upkeep and care.

Wait, upkeep? What happened to endless energy?

Yes, upkeep. You’re creating something to funnel energy, with energy. Energy needs to constantly be molded and kept in shape, or else it tends to just drift away. It really isn’t that hard to upkeep, though.

How do you keep your energy tethers safe from other people? 

Just program that into them when you make them.

Any disadvantages to using an energy tether?

It depends on how you view the term disadvantage. 

I think the thing that energy tethers lack is that bit of personalization that we often talk about being important in witchcraft. For example, you can keep a thoughtform powered by the sun, but it won’t contain your energy, won’t be as personally tied to you as if you charged it with your own energies. That can lose a lot of impact, when you really think about it, especially considering the nature of thoughtforms and the like.

Not to mention, you can overwhelm yourself with energy if you use a tether to connect yourself to an external source that produces more than your body can handle. You know how you can be overwhelmed by external energies, just by walking around? Yeah, now imagine that pumping straight into your body without a natural exit channel. Not fun.

Are there any other applications for energy tethers?

Fuck yeah. Use them to draw energy out of a target, in the form of a curse - literally sap their energies away so they have none left for their daily lives.

You can even connect yourself and another person with energy tethers, if you want to be able to share energy more freely and with more ease. (This is basically what I did with @ashesforeverashes​, in a sense.) 

Some people don’t like their energies taken without consent, though, and certain witchy protections can even prevent these sorts of tethers from forming in the first place, so keep that in mind.

Okay, all this talk about tethers, are you gonna show us how to make them?

Only if you ask nicely.

Please?

Okay that’s better. 

It is essentially just a combination of energy work, intent, and visualization.

The first thing you need to do, is have an object you want charged.

Now, pick an energy source. You don’t need to be able to see it, but it can help.

Relax yourself, clear your mind if you can. Hold onto your object in your hands. 

If you can, look at your energy source; this is clearly not applicable with the sun, so close your eyes and have your face turned toward it. If you can’t see your energy source, picture it in your mind as clearly as you can. Try to get a feel for its energy as well as you can, too. 

Once you are confident with your source, imagine a cord connecting from it and to your object you want to keep charged. A nice visualization for this would be seeing the particles form together out of thin air to form your tether - literally materializing out of nothing and attaching to the source, creating a line that is slowly building down from the source and to your object. This can be done in whatever way you wish - just make it.

Take as long as you need to allow the cord to be build from your energy source to the target - it can take some time, depending on the distance and how experienced you are with energy work.

While you are creating it, focus on any attributes you want it to have - a thick cord that is hard to break, a shimmery appearance so no other magic users can see it, etc. Keep in mind the purpose of the cord, what you want it to do, how you want it to behave, and fuse that into it as it is being formed. If you wish to incorporate a switch, in order to turn on and off the flow of energy, now would be the time to do so - more visualization and intent, and declarations of “I can halt this flow of energy whenever I desire” should do the trick.

Once the cord is in place, you want to draw energy from your source and into the object, through the tether. Make it clear that energy only flows one way through this particular tether. Continue to draw from the energy source and down into the target, until you begin to feel the energy flowing through the tether naturally. Once energy is accumulating into the object on its own, you know the tether is complete.

For the upkeep; about once a week or so, focus on the tether and visualize it still being strong, without any gaps for energy to sift through. See a smooth, clean flow of energy from your energy source and into the target. If there are any obstructions, break them down and funnel them out.

What was this “representational magic” method you mentioned?

Oh yeah. 

As a boost, you can have a representation of your energy source physically attached to the object or target, if you can. So, for example, you could have a tiny model of the sun, connected to the physical vessel for a thoughtform, by a piece of string. This can help keep the energy tether strengthened in a “physical” aspect, especially if you bind the physical to the energetic. Not to mention, just looking at it, you are reaffirmed that the tether is there and the object is charged, and that can assist with the upkeep.

Are there any “modifications” for energy tethers?

Totally. You can change the “material” you make the tether out of. Think of how people can put spikes onto personal shields, or make them have reflective surfaces - it’s sort of like that, but moreso changing the tether itself into something besides a beam of light. It can be a black cord like the ones electronics use; it can be made out of natural rope or hemp; it can be just a metal pipe that the energy slides through. Try to think about how each “material” might impact the flow and/or feel of energy.

You can also have one tether break off and charge many items at once - you don’t need a separate tether for each thing. Just focus on your tether and how it can fork, and imagine another branch coming from it naturally. Or, if you’re adding a separate line after the original tether has been “installed,” imagine a separate line growing or being molded from the first and down to the new object.


And there you have it - my post on energy tethers. Obviously this isn’t complete or all encompassing. This is just my view on these energetic cords, what they are, and how they can be made and used. I wrote this off the seat of my pants, but I think I covered everything I intended to. (And it feels hardcore like the old windvexer posts to me, which I’m not bothered by lol.)

I hope this helps you guys, or inspires you, or whatever. If you have any more questions, I… guess I can open my ask box, as long as y’all behave. Good luck, and have fun!

🌟 After a long time of waiting, you came to me. After years of being alone, I can breathe again. The sight of you sparks thoughts I’ve never tried to have. Of living. Of a home. Of friends.

the untitled poem

Unfortunately

Sadly enough

I will never be able to tell about all

Those nights,

Like the one

Atop an air mattress

Where i lost all my faith in god

Or when that orange vase went crumbling to the floor.

Or the night when i found out that battery acid flows through my veins

And that there are spiders brooding in my bones.

I will never tell you about the blue light, or the skeletons, or how i know where purgatory is and i can’t listen that song anymore without thinking of it.

Or how when the bath water reaches my collar bone, i can’t help but cough up sea water that i have never swallowed.

I will never tell you about those nights with the poems, and the wrists too swollen to hold a pen.

(I will never tell you about how i feel i am a broken doll.

Over worked joints, chipped porcelain lining a mouth with no voice.)

i want to tell you about the manic episodes and the wild goose chases to find a paintbrush so that i may create oceans on my arms.

I want to tell you about the days when i didn’t part my lips for 72 hours just so that i could feel lovely.

Or the night kneeling marble, when i discovered my body was broken. I will never tell you about the letters of the fear of my gagged mouth,stuffed with apology. I am sorry.

We are no longer in love and its

(not)

My fault.

anonymous asked:

Hi there. I want my MC to hack or manipulate either a phone into exploding and setting off the fire alarm, or somehow set of the fire alarm. Basically I need the building to evacuate without there being an actual fire, or not one that my MC doesn't remotely cause. Is there any way that I can have that happen? Thanks

Oooh, distraction time! Don’t Try This at Home (or anywhere else for that matter). I’m also not going to go too much into detail in case some clever little bugger decides they want to set off the fire alarm and go home from school early by setting off an exploding phone.

That said, let’s get started.

There’s always setting off a smoke-bomb to trigger the fire alarm, even put it on a timer and hide it in something innocuous, but I don’t suppose that’s quite what you’re looking for if you’ve come here.

Now, did you ever hear about the Samsung exploding battery stink? It was all over the media for a while, got banned on planes and all sorts of fun stuff, ended with a recall (two, actually) to fix the issues. This could very well fill your author needs, especially if your MC has access to the phone beforehand and at least a basic understanding of electricity.

One of the problems with the Samsung battery was the positive and negative terminals of the battery degraded quickly, and shorted out the battery circuit. When this happens, the entire voltage of the battery flows through the resistance of just the path between the terminals and the internal resistance of the battery itself. Long story short, high current flows through the battery’s internal resistance causing rapid heating, which causes gasses to build up, pressure to build up, eventually leading to a lovely dangerous kaboom.

Your character could take advantage of this and, with a little technical knowhow, rig up a system that would short the phone’s battery on command. It would probably take a few seconds to get going, but your character would probably test this beforehand to see how long it takes and decide if it fits their needs. Scientific method, people.

Getting in and tampering with the phone, your MC could create a new path in the complex circuit that is their phone. This path would basically amount to a switch that, when power is applied in the correct way, connects the terminals of the battery and causes the short. This switch could be a transistor, a solenoid, or anything that brings the terminals of the battery into permanent contact somehow. Hook the other end of this new path into a part of the phone that is only given electricity in any great amount at certain times, and viola.

With this setup, your MC could call the phone, set an alarm (specific time or length of time), or do any number of things to trigger the short. Place the phone well, and the fire alarm will probably go off.

Your MC could also just tamper with one of the fire alarm switch housings in the same manner, creating a switch that closes and sets off the alarm upon a set of conditions being met, get a small timing circuit driven by a ten-cent timer IC and a battery. This would mean having enough access to one of these housings to figure that out, however. It’s probably fairly self evident but it is worth mentioning that tampering with or falsely activating safety systems is illegal. Don’t do this.

Of course, your MC would have to be very careful or they’ll be caught when the burned phone is found and the cops called. Fingerprints, a stray hair, the various unique numbers associated with the phone, the sim card (and more), all relatively trackable.

And seriously, don’t try this at home. C’mon, people.

@two-stomach I was going to write you fluff but then I thought of an au where Danny is on a colony on the moon and it just kinda went from there,,,,,, my bad?


“Commander, requesting permission to chase after the meteor to look for a fucking cool rock.”

Commander Para signed into her mic, before shifting her stance against the bulky space suit designed for doing EVAs on the rocky surface. “Request denied, Fenton. Orders from Houston to stop chasing the goddamn rocks.”

“They’re just mad that they can’t stop me.” Para rolled her eyes as Fenton transformed, his already lightweight spacesuit turning invisible as he flew off. The cloud of meteors could tear through his suit and his oxygen tank if he wasn’t careful.

Zootopia: Outback Island

Finally tackling another District, let’s take a look at Outback Island. This place has actually gotten some attention in the budding franchise, being a featured in the beginner’s book “The Stinky Cheese Caper”. Therein we learn that those who inhabit the island are collectively referred to as “Outbackers”. A list of animals that includes: dingoes, koalas, wallabies, platypuses, and kangaroos from which can assume species like bandicoots, tasmanian devils, and echidnas also exist. Only a few small stores are mentioned with the only prominent land mark being The Old Outback Bridge. The underlying theme behind Outback Island is their feeling of separation from the rest of the city. Their island status puts them away from Zootopia’s heart. Which in turn has lead to them feeling neglected, their particular grievance being that the new “Bridge to Everywhere”, inferred to be a new super highway that interconnects the city, skips this district which in turn suffices with an old, Ill managed bridge. While I think every district carries within an independent identity, Outback Island’s was formed rather involuntarily and carries certain bitterness to it that I don’t plan to lose.

Since Outback Island is an unabashed replica of Australia, a question rises as to whether it should also reflect the various climates located therein. Interesting then, to have micro controlled environments on top of a macro one. Though the practicality of this idea would largely depend on how big this “island” is. When you have differences like the Canyonlands inside Sahara Square and The Canals inside the Rainforest District, I don’t think it’s too big a stretch though I think a lot of the differences would be limited to different flora. For now, I think it’s practical to say Outback Island would be hot environment largely made up of a sandless desert with mountain fronts situated at various points.

Situated on all sides by water and only one “convenient” mode of transportation to and from the island, its isolation plays a key role in the industries and locations therein.

Away from prying eyes and in appeasement of those who consider their presence incongruent with the image of Zootopia, Outback Island is where the military makes its home. Taking up quite a bit of space, Joint Base Bold ensures the miracle city is not without defense while the island acts as the most defensible position in the area. From Harbringer Harbor the naval forces deploy and keep international trade flowing. Leather Wing Battery runs several missile defense systems that stand ready to shoot down any air threats while Camp Claw makes use not only of Outback island’s unique environment but frequently exploits Zootopia’s other climates in training personnel. The base would also be the location of The Black Buildings, where the nation’s spy agency, MIA, makes its base of operations for Zootopia. There is a saying for these windowless monoliths: “The one you enter is not the one you exit, the one you exit is not the one you do business in…except when it is.”

On the opposite end of the island stands Open Paw Prison where Zootopia’s convicted spend their days. While light offenders get “cozy” in The Meadowlands Jail, those in for a long stay find themselves where the heat is. Placing prisoners on an island was an easy decision: some wonder the wisdom of putting criminals so close to a place filled with weapons but proponents argue taking said weapons would prove far harder, and more lethal, to obtain than breaking out of prison in the first place. Outback Island is also home to Zootopia’s primary sewage treatment plant and Landfill, which to the ceaseless irritation of the district’s normal inhabitants can often be smelt across the island on windy days.


Outbackers often consider themselves a day behind anything happening in the rest of the city. New product or movie? Get it the day after. Fresh fish from The Docks? Day old fish if you didn’t fish it yourself. The culture is insular, not only have most come from the same country but regard getting off of the island as inconvenient as getting on. Being labeled an Outbacker comes with its own set of stereotypes that become just as tiresome and annoying as racial ones, not the least of which is being pigeonholed as “The Foreigner” in a city filled with immigrants. Local skilled professions often get Outbackers labeled as a “dirty” and “rough-and-tumble” lot.

The local police station also takes particular offense whenever Headquarters feels the need to send people from off the island into their territory. The Military Police prefer to handle anything involving their personnel, even for off-base incidents which is compounded by MIA’s watchful eye. The friction between Headquarters, local police, the penitentiary, and security forces can create more drama than necessary at times: particularly for two cops who don’t know the meaning of the word “boundaries”.

In the greater story of Zootopia, Outback Island would be a frequently visited location when the duo’s defeated rogue’s gallery need to be interviewed. It would become the primary location in stories that focus on military drama, espionage, prison breaks,  and revolt of the marginalized. It would also be home base for Nick and Judy’s Foil/Rival Joejack, as well as the territory for the Zootopia’s second villain, who made his appearance in the previously named book, the platypus Singcor Swim (well…it’s a step above animal puns) and his revolutionary gang.

Interesting to note that Singcor Swim actually saved Judy from drowning when his stolen cement truck careened off the bridge, an action that led to his swift arrest. He is a trouble maker but ultimately not a murderer.
