1000 gallons of water really isn’t that much. Like, Lake Mead has a capacity of 9 trillion gallons. Even if this ability is every six seconds, you couldn’t refill it in a lifetime, and while that’s one of the more visible symptoms of the water shortage, it’s only a small fraction of it.
1k gallons of water is probably a zero problem near a large retaining body. No argument. But every day if you AREN’T near one? Are you going on a (non-boat) international trip? Is your local watershed able to absorb it without running off into a nearby property when it happens EVERY DAY?
No, as I said, I put that in the likely upper limit of successful options, but heck, I’ve had friends get sued because the drainpipe from their gutters poured water onto the adjacent property and caused washouts. Planning for excess (and insufficient) waterflow is probably some of our oldest, if not THE oldest technologies we have. Never assume it’s easy.
Now, granted, if @TruCelt didn’t travel much and has a nearby lake, it’ll probably never be an issue, but it would be for ME and probably for some others at least. Not a deal breaker, but it might become a once-daily chore to head over to a safe dumping place.
Yes, very easily. Again, 1000 gallons is an absolutely trivial amount of water. Even if she ups it to a level that can help with shortages, there’s such a huge difference between a load of water every time she snaps her fingers and a load of water once per day that it simply can’t be a problem.
That was my first thought. On reflection, I’d probably just settle for one-ounce of 50 gram or whatever gold bars. They’re just as fungible, and you won’t have as many questions about where you found the cache of rare coins.
And if I create just one gold bar/coin every 24 hours, I can cash them in one at a time and avoid a lot of questions, or save up for awhile and buy Elon Musk.
I think some gold bars are serialized but gold coins are not which is why I suggested gold coins.
And to give you an idea of just how little a thousand gallons of water is, an acre-foot of water is what the “average” suburban American household uses in a year and that’s 325,851 gallons. So if you’re producing a thousand gallons a day for a year, that’s roughly only as much as one household uses.
I’d pick iridium instead of gold. I could easily go to a rare metals dealer and ask to hold an ingot for a moment.
I wonder if I could get a “rare earth metals” semi loaded up, with quantities that would be meaningful. Could I change the world by spending a couple of hours a day going to a shipyard and just bink bink bink creating a few hundred (or a few thousand) cargo containers full of rare earth metals?
It looks like the US has topped out at using 15,000 tons of REMs a year. That sounds like an manageable quantity to produce in a day’s work (a cargo container has a payload of 24 tons, so if I could make a full container every minute, I’d need a little more than 10 hours).
I definitely think that solving the energy crisis is the way to go, and probably that’s gonna mean removing bottlenecks for creating renewable power plants. Is there a better bottleneck to remove?
Okay @Dewey_Finn and @Chronos, I’m going to try to explain this one more time, because IMHO, you keep comparing apples to oranges and ignoring the circumstances of the OP.
Last part first - UNLESS you are replicating a container HOLDING the 1000 gallons (at which point, you have a huge container that’s now conspicuous waste depending on what it’s made out of), you just created a globe/cube (guessing how the genie would replicate it) of water that is created adjacent to you which immediately follows gravity.
It’s, granted, not an earth-shattering amount of water, but it’s about twice what you’d see in a 7 person Hot tub.
Before you started trying to nit-pick, I fully granted that it’s fine if you have a lake, good sized stream, or drainage ditch nearby, and even if not, it would probably be a small chore to go locate one where you could dump it, remember:
Which you both seem overly willing to ignore. But if again, you’re travelling, or otherwise away from your usual haunts, it will require more planning. I never said it was impossible, or even truly difficult, I just said it was an amount at the higher end of the likely useful range by volume.
And, extra reverse nit
But we’re talking about 1000 gallons in a second. Which, if we’re talking about an average household, is like having ten 100 gallon water heaters explode in your HOUSE all at the same time. Excessive and perhaps silly example? Sure, but so is your annual household use counterpoint. You aren’t disposing of it via the usual drains, that’s for sure.
I REPEAT though, it isn’t difficult to deal with, it just requires planning for the sudden creation and removal of, especially since it has to be done at least once a day even when you aren’t planning on filling lakes. And doubly especially if you don’t want to get exposed.
I’m thinking maybe this, but in the form of a large ice cube (I’ll go for a metre cube, so 1000 litres), because it’s still just water, but it also offers the opportunity for it to be used to keep stuff cool, and also means you could produce a lot of it* in a relatively flat place and it would not create a flash flood that would drown you, indeed you could visit somewhere like the Great Green Wall project and deposit cubes of ice in a long row from the back of a moving vehicle, where they would melt over the course of a few days, gradually watering the soil without causing massive runoff.
*I might have missed it but I don’t see anywhere that the OP specified the frequency at which the ability could be used (other than the minimum of once per 24 hours).
Alternatively (and I am not sure how the genie might interpret this), but I could contrive to visit somewhere that a very powerful and voluminous jet of water is being emitted, and very carefully touch the jet of water - which I think would imbue me with the ability to create a similarly powerful and voluminous jet of water at will (presumably that stops flowing when I stop using the ability, so I can just turn it on and off as required)
I’d go for some sort of blank bar of gold. Bars and coins are stamped by some sort of official organization that would frown upon me copying their design over and over. Partner with a gold recycling/buying outfit (or start your own outfit) and you’ll make a fortune.
Making gold via magic isn’t illegal, make a business of it.
What about gold dust?
Saleable, and untraceable.
Or, 1000 kilos of saffron.
The problem I see with all the ‘produce something valuable’ ideas is that if you start to be able to spend a lot more than your visible income, sooner or later the tax authorities are going to get wind of it and come after you. Which isn’t going to be good in any number of ways.
If you deny the ability, they will just get you for tax evasion. If you admit it, an even more sinister government agency will step in, and you will be whisked off to a secret laboratory for study and ultimate dissection to try to replicate the phenomenon.
Maybe there’s a clever way round this, but it’s not obvious…
My plan (I earlier said I didn’t want to do it, but was very grumpy) is a trick that works here in Colorado on a small scale, and is legal as well as easily accounted for in terms of getting access to the valuable. My Father-in-law is fond of the period of American westward expansionism, and one of his hobbies (well, not so much these days, due to age but earlier) involved doing recreational gold panning. He has a jar of gold dust and flakes accumulated over a couple of decades, probably 3-4 ounces worth (no, it’s not really profitable normally).
Gold panning, as long as it’s not destructive, is allowed on small scale even in the national forests here, although actual nuggets and chunks are normally required to be turned over to the state. I could replicate the few ounces my father has, make some efforts to gold pan (he has all the equipment after all), and slowly convert the gold to cash while making sure to declare the source and income on my taxes.
I don’t think I could do it on sufficient scale believably to stop working entirely, but I’d probably be able to only work part time, and I might sell some of it based as much on it’s artistic/collector merit as the actual gold value - the same way people pay for gold “certificates” made with some real gold, but in excess of the actual metal value.
A chicken.
I’m gonna make a chicken. Every. Single. Day. Lots of chickens.
Why?
First of all people love chicken, all people. Everywhere on earth, love chicken. I love chicken, could eat it almost everyday!
It won’t be hard to give them away, they’re free. I’ll be very popular I expect. I could help the poor and starving anywhere I go. Here, have a chicken or ten!
You know what’s almost as good as chicken? Eggs!
(I’ll be giving away eggs too!)
I would create copies of me. 
I’d have someone who shares my views and can play bridge + chess with.
It might be embarrassing to over-populate … but maybe I could persuade a few copies of myself to be organ donors. 
(Alternatively I’ll go for a chocolate eclair. 
)
Soooo…Where can I find the best coffee in the world?
Edited to add: According to many lists Panama Esmeralda Geisha Special seems to be the best. I would pick up a 5 lb. bag, and had it out for gifts.
Well, let’s assume you can materialize gold, as per the OP postulate.
So, you hint that you have a better solution to Haber’s gold from seawater project.
‘When Germany Tried To Turn Seawater Into Gold - KnowledgeNuts’
You hire some competent but not very critical engineers to build a big sciency facility at the coast, which pumps a lot of seawater around, particularly through the proprietory ‘extraction reactor’, which is of course top secret and only known to you. Which is where you materialize the gold.
You don’t, of course, try to take this public or patent it, so you are under no obligation to publish or reveal anything. And the EPA can test your outflow all it wants… it’s all completely harmless.
You do need a bit of seed money, but assuming you can materialize gold, that shouldn’t be a problem?
As long as you report your income, and pay your taxes, what are the tax authorities going to complain about? I suppose the police can claim you stole the gold, but they wouldn’t have any evidence, no stolen gold complaint, no link from your gold to stolen gold, and you can afford a really good attorney with all your gold money.
I’d say the biggest risk is becoming the goose that laid the golden eggs to some unsavory people. Best to keep your head down, have a business that can legitimately sell gold, then sell it quietly and pay your taxes.
Maybe, if you keep your head down and you’re not already on their radar?
Though Al Capone’s downfall was (supposedly) caused by tax irregularities.
