Many of the forests there were originally swamp and small dams can reverse that.
Shower head 🚿 is horrible at distributing water over my body. This is not only annoying because you need to constantly rotate or move it around your body, but also wastes a lot of water. My shower head has around 50 spray nozzles, and I often imagine them being distributed in a spiral around me.
So, the idea of the shower coat is as simple as a raincoat, but with an attached hose on the inner side with spray nozzles arranged along the hose.

I have been coming up with something I call the 2030 Plan. I believe Canada, the United States, Mexico, Belize, Costa Rica, El Salvador, Guatemala, Honduras, Nicaragua, Panama, Antigua and Barbuda, Bahamas, Barbados, Cuba, Dominica, the Dominican Republic, Grenada, Haiti, Jamaica, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Trinidad and Tobago, Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, Venezuela should all be united under the flag of the United States.
Why is this? It is because I believe one day, all people of Earth will be united as one to push our civilization beyond our planet, and I believe a union of the Western Hemesphere is the first step to this grand plan. It will eliminate the southern border crisis and the border altogether, which will bring our attention back to the issue of expanding our civilization into space, creating space colonies and colonies on other celestial bodies. I believe this is the key to not just making Amerca great, but I believe it will make America invincible.
What if you took one of those dual piece keyboards (where the left half of the keyboard is separate from the right half), and mounted them on your belt so that it hangs down towards your thighs.
Then you can stand and type, without being constrained to a desk. Type like a rockstar at a concert.
Hello everyone.
I introduce to you my concept idea called a 3D scan balloon. I want to get your opinion about it.
The idea is a new form of a 3D scanner. But instead of visual, it uses touch.
The idea is that an object is placed inside a special balloon. And the balloon is then vacuumed until all the air is pulled out of the balloon, making the balloon take the shape of the object.
All over the balloon are sensors—thin film pressure sensors that detect the shape of the object.
I now it's not going to be the next big deal. But I wanted to share the concept with you.
Thank you very much.
The r/apphookup subreddit usually has some pretty good freebies for iPhone... Sometimes they have some Android stuff and other platforms too. But I guess on the back end it would be nice if more developers would promote their stuff when it goes free for Android
I recently bought Insta Doodle to make a whiteboard explanation video for a sales page that I was creating for a client. I'd normally outsource those videos from Fiverr but Insta Doodle is essentially the same price, so the cost is just the time investment, which is minimal. It sort of saves time because you can build exactly what you have in mind, whereas on Fiverr you have to explain what you want and then review the deliveries and get revisions which is time consuming. Anyway, I think using Insta Doodle to offer whiteboard videos on websites like Fiverr, Freelancer and Upwork would be an easy business idea to implement. The software's easy to use, there's basically no learning curve as it's self-explanatory so anyone can implement this idea. You could also sell on your own website at a steeper price and cold email businesses + advertise in small business Facebook groups.
Food for thought if you have time and want to start a side hustle that could blossom into a full-blown business. Here's a link to Insta Doodle if you want to try it - Link here
I am looking to buy or build a similar experience to Apple's Macbook Magsafe connectors, but for anything that plugs to my wall outlets. I find constantly connecting and disconnecting devices that share outlets (in my bathroom alone I have an electric toothbrush, a hair blower, and an electric shaver) and I'd really wish it was as easy to disconnect and connect as my Macbook Air's Magsafe adapter. Now, I looked around and can't find a single product for this other than this one made by a product studio in Oregon which is out of stock (also can't find any reviews online so can't tell if it ever shipped).
The idea feels obvious so I'm surprised no one has done it. I don't think there are any laws of physics that would make this impossible? Is it a case of a patent or regulations blocking this?
I'm sure the Magsafe engineers at Apple have thought of this :)
So basically, detonator built to look like a gun, actor has blood packets under their clothes. Each time the "gun" fires it will cause a blood packet to explode.
Is it even possible? That may depend on what else is mixed with it and how much.
Google should give users the ability to select/ deselect (deactivate/reactivate) Google apps and services from Google accounts. For example, if we want a specific Google account to be *just* for Google Chat, Gemini, tasks, and nothing else, we should be able to go to our Google account webpage and deselect everything except for Google chat, Gemini, and tasks.
Then, when signing into that Google account on any Android or chromeOS device, the account would *only* appear in Google chat.
Would be a nice way to avoid cross-account data leakage via all of the other Google apps and services. They're great services, but I think we need the ability to deactivate specific services if we desire. and then of course we could always reactivate services if we desire.
Another way Google could achieve this is by letting multiple users access private space. Currently, private space is only available for the default user, and not for a second or third user profile. It would be nice if Google would allow setting up the private space functionality across multiple users, so that users with multiple Google accounts could access sensitive account in a sandbox (private space)
Yet another way Google could achieve this is by allowing “Login with Microsoft” or “continue with Microsoft”. Since Microsoft is not a Google property, it might be occasionally nice to have the ability to use Google apps and services with a nongoogle entity. This can help with the ability for a user to only sign up for specific services, so for example, if the user only wants to sign up for Google chat, and not the hundred other Google apps, “login with Microsoft” could sort of allow that.
Imagine a social app where you can say it all without text, photos, videos, audio... JUST draw, share and express yourself. ✏️💭
There's still a lot to develop and your support and feedback will be the key.

it would be nice if google docs had a native option to lock content / lock specific doc tabs etc...
like, where it would require a person to do touchID or faceID or screen unlock on their iphone/android or similar on desktop web etc to access the content of said tab or something...
if you're sharing a doc with someone and it's kind of maybe sensitive, you could enable the feature so that they'd be prompted to faceID/touchID etc. or the ability to do it on individual document tabs, so the entire file itself doesn't have to be protected, but individual tabs could be. i think would be appreciated.
This idea came to me from my last Reddit comment that came from a user who suggested that if you buy Apple products you should get Apple Music for free. I suggested that this was a bad idea, and offered a potentially better idea of discounting streaming services by offering multiple services in one package. I will elaborate on this below.
So, my idea is to take the most popular music streaming services and bundle them together for one price that would be MUCH cheaper than separate bills. How could music streaming services afford to do this? Simple. If the account is individual, then only allow one stream combined with all services. An individual never needs to listen to more than one stream at a time, but if you are only streaming from one service at a time, the royalties would then essentially stay the same because companies pay per stream.
For example, you sign up for a service like this, and play something on Spotify. You then, for whatever reason, log onto a different service and play music on that service. There wouldn't be two streams - your Spotify stream would pause as a result and whatever you streamed on whatever service you started playing with would start instead. Always one stream, no matter how many music streaming services you bundle with.
This wouldn't necessarily make it more expensive for the streaming companies, but, in return this new "feature" they promote could raise their rates somewhere between $15-$20 per month for an individual and higher for multiple streaming, like families using it. Being able to access any music streaming database would be highly beneficial to a lot of people who would pay extra for this feature, even if they are still limited to one stream. I know programs would have to find a way to detect a second stream on other services, but it should be possible to do so.
With the idea that you could bundle music streaming services at a higher rate, you could attract a lot of people who are into music but have friends on multiple platforms. For example, I mostly use Spotify to share with my friends, but I do have a close friend who uses Apple Music and wouldn't mind paying an extra couple of dollars each month to be able to use his service. But both Spotify and Apple Music separately are $12 a month and I can't justify paying $12 per month just to share music with him. But if the combined services were say, $15 per month as one bill, and one stream, I would probably sign up to something like that.
And you could make it so the more services you bundle, the higher the rate could be. Combine two services at $15 per month, but maybe you could add three or more for a couple of dollars more. Again, the services aren't paying more from your subscription because you would still only be allowed one stream at time, even if you had access to several music streaming services at a time.
The more I think about this, the more I wonder why something like this hasn't been implemented. It sounds like the perfect way the music streaming companies could nickel and dime us while at the same time not paying extra per each customer.
Hey everyone, I’ve been toying with a hypothetical concept for generating energy on the Moon (and potentially beyond). What if we could design an orbital system to harvest kinetic energy directly from the Moon’s rotation around Earth using relatively simple magnets in orbit?
The Concept:
The basic idea involves sending a swarm of strong magnet-equipped objects into carefully designed orbits around the Earth and Moon. These orbits would take advantage of gravitational assists (swing-bys) from the Moon, where the objects would steal a tiny fraction of the Moon’s orbital energy, accelerating in the process.
Once they’ve been sped up, these objects would then pass through low orbits around the Moon, where they would fly through electromagnetic induction rings or stations on the lunar surface. As they pass through these rings, their kinetic energy would be partially converted into electrical energy via induction, slowing them down. After this energy extraction, the objects would swing by the Moon again, repeating the process in a continuous cycle.
This method taps directly into the Earth-Moon orbital system, siphoning off a very small amount of energy from the Moon’s motion around the Earth.
Key Mechanics:
Orbit Design: The challenge would be designing stable orbits that allow for continuous gravitational assists and low-altitude passes through induction stations. The swing-by effect from the Moon must give enough of a boost to compensate for the energy extracted when passing through the magnetic rings.
Minimal Control: The magnets themselves would be simple, with little to no need for control nozzles or complex maneuvering. The orbits would do most of the work once they are established.
Energy Cycle: Each magnet would complete the loop by repeatedly gaining speed from gravitational assists and losing speed through electromagnetic induction.
Key Calculations:
Disclaimer: This is a very rough and optimistic estimate, and the true viability of such a system could vary wildly depending on many factors, from technological feasibility to cost assumptions. The calculations and assumptions could be completely wrong.
1. Energy Gained per Magnet (Kinetic Energy):
ΔEkin = 1/2 * m * Δv^2
Where:
Mass of each magnet (m) = 250 kg
Delta-v gained per swing-by (Δv) = 500 m/s
Energy gained per magnet: 31,250,000 J (Joules).
2. Power Output per Magnet:
P = ΔEkin / cycle time
With a cycle time of 10 days (864,000 seconds):
Power output per magnet: 36.17 W.
3. Number of Magnets Required to Meet 1 MW Demand for a Lunar City:
N = Ptotal / Pmagnet
To meet the 1 MW power demand:
Number of magnets needed: 27,648 magnets.
4. Total Energy Generated Over 30 Years:
Etotal = Ptotal × operation time over 30 years
Total energy generated: 262,980,000 kWh.
5. Total Cost (Launch + Magnet Production):
Total cost = (Launch cost per magnet + Magnet production cost) × N
With:
Launch cost = $150/kg
Magnet production cost = $10,000/unit
Total cost: 1.31 billion USD.
6. Cost per Kilowatt-hour (USD/kWh):
Cost per kWh = Total cost / Etotal
Cost per kilowatt-hour: 4.99 USD/kWh.
TL;DR: Introduce a "Kaufkraft-Euro" (KK-Euro) to display inflation-adjusted prices and wages alongside regular Euros. This would give people a clearer understanding of real value changes over time, making it easier to see if prices and salaries are rising due to inflation or other factors. It could be implemented gradually in retail, payroll, and banking as an optional feature to enhance transparency without disrupting current systems. Thoughts?
A Simple Way to Display Inflation-Adjusted Prices and Salaries for Better Transparency
I've been thinking a lot about inflation lately and how it affects the way we perceive prices and wages. It's always frustrating to see prices go up, but it's even harder to know whether that increase is just due to inflation or if the product has actually become more expensive in real terms. The same goes for salaries: Is a pay raise really a raise, or is it just keeping up with inflation?
This got me thinking: What if we had a system where every price and salary was displayed alongside its inflation-adjusted equivalent? I’m calling this hypothetical unit the "Kaufkraft-Euro" (KK-Euro), which is German for "purchasing power Euro." The KK-Euro would be based on a fixed point in time (let’s say the year 2020), and it would stay constant as long as the real price of the product or the real value of a salary doesn’t change.
How Would This Work?
Why Is This Useful?
How Could It Be Rolled Out?
Conclusion
By implementing the Kaufkraft-Euro as an optional feature in retail, payroll, and banking, we could give people a better understanding of the real value of their money. Inflation wouldn't feel like an invisible force eating away at our wallets, and both consumers and workers could make more informed decisions. In a time where inflation can often feel confusing and overwhelming, this could be a simple and practical solution for transparency.
What do you all think? Could this idea work, or are there potential pitfalls I haven't considered? I’d love to hear your thoughts!
I am pretty bad with electric stuffs lol but my girl ask me to fix this. Help a bro out
When it comes to therapy, there are lots of options - Talking therapy, antidepressants (psychiatric therapy), cognitive behavioral therapy (which is just a fancy way of saying face your fears), Music therapy, laughing therapy, etc.
But I'm surprised that there's no such thing as "Math therapy".
I'm not really a big fan of math, but whenever I have been traumatized or depressed about something, I've found that math and programming has been an almost 100% painkiller. If you're solving a hard problem, it completely immerses you in that, and makes you forget about what was originally hurting you.
Just like video games and movies....it's a form of escapism. But I think its much better to lose your mind to math than to some mindless video game. You'll only be strengthening your mind and improving your career prospects.

I'm a college student with a class project that is failing right now. I don't have enough people taking my survey. It's to research solutions that will be later turned into an app design.
It's about a 3-minute survey, and it's about how you enjoy playing sports and if you want people to play your sports with you. It would really help with my design project!!
It is completely anonymous.
As a kid, I've always loved donuts and other pastries. But as an adult, I cannot enjoy it anymore just knowing what it does to the body.
Notice that it also makes you feel like crap after you eat it. Because it's junk food. But protein based pastries also taste like crap.
So how about this - A pastry shop that makes all the stuff that you love. But instead of flour, it uses whole grain. And instead of sugar, it uses fruit (jam or syrup) and honey.
Here's the motto: "Good stuff.....for the tough.....without the fluff"
Ontop of thumbs up/thumbs down there is a star or heart button. This button adds it to the ambient queue. In ambient mode netflix shuffles all your favorited shows (in sequential order but still mixed togeather) and movies. It always starts you where you left off mid viewing and will restart a series if it reaches the end. Bonus points if you could configure sequential or randomized episode order per series.
You should also be able to filter to and manage your favorited titles. With maybe 5-7 recently removed titles that roll off the list as you remove titles.
Ambient mode can either be selected to be viewed full screen with no interruptions or be set in settings to begin after the end of the first trailer in the main menu with trailer interuptions every 7-10 min.
Edit: Bonus bonus points if you can download ambient mode and it will automatically manage download/deletion roll over as you watch on the specific device.
It seems kind of logical to think that taking existing rock could be cheaper than making new "rock" partially from scratch on the molecular level with chemical reactions on site and in the cement factory.
Old buildings tend to have more stone block parts than new buildings. Did the price balance shift in favor of concrete? Maybe some new automation methods related to stone cutting, moving and ultrasound inspection for defects could shift the balance back to favor stone blocks? Different areas of the world have different rock types and that matters too.
In many places it could be possible to cut the stone blocks from under the building site. Usually with circular saw, or maybe even with heat or acid...
The cut surface area has a price, and enough volume per cut surface area may make the blocks cheap enough for their size. Walls may be unusually thick and that is good for sound proofing. Maybe not so good for thermal insulation but better for thermal inertia.
Vertical parts (walls) rock blocks and horizontal parts reinforced concrete and / or wood. Narrow spaces (2m?) could be covered with long stone blocks. Arch structures are also possible...
Rock looks more interesting than concrete, even if painted white.
They always expect the consumer to make environmentally conscious choices. That's nonsense. Consumers buy whatever's available if the price is right. The responsibility is on government and retailers to not sell environmentally inconsiderate products.

YT is in the arms race against ad blockers and ironically making ads more and more frequent and annoying. But I wouldn't mind ads, especially if I fall asleep during a video, if the ads were muted. I could watch a video, realize an ad came on, do something else, and wait for the audio to come back to know it's time to resume watching.
A silencer is a compromise between prioritizing myself and supporting the content creators I enjoy.
I have realized the fact that public opinion, reputation and dignity don't exist and what I mean by this is that these terms are used in society to put pressure on people and create insecurities, ruin people and destroy them by making them worry about the opinion of others which btw even ur friends aren't permanent because of changing interests what not. So the fact is you shouldn't worry about what others have to say, a dark harsh truth is that your nephew won't know much about you if anything. Life is short and unpredictable and I live it happy, I enjoy my own company, I don't need other people to be happy im happy because I am strong and resilient and im proud of myself because of that, you have to live in the present, enjoy the present, enjoy the moment. Im not a slave of others, im independent of others even if 100 million people hate me I'll still smile, I will smile because I know im king regardless of what others have to say about me and you can easily disconnect and ignore everything, say to yourself im king and I don't care about what others have to say. Heck, even what im writing here is worthless scribbles and letters that make sense because you value them, they don't want society to understand this truth, they want young men to fight over reputation, over girls that don't even like em because we value people who don't reciprocate feelings basically less is more (another manipulation technique) the media, fake analysts want kids and students to have depression, why because they tell people to value words, so when someone say insults you in class the media and society wants you to suffer and think about that insult 24 hours when you can simply say thanks for ur opinion don't give a shit and live your life happy, they're like but oh people heard that and now your weaker and they want you to feel bullied inferior because you got insulted, because you heard some meaningless sounds. Its all up to interpretations, you can choose to be happy and Confident in yourself and tell yourself that you deserve the best regardless of what others say. Shame on society, shame on them for wanting to slave young students and kids with their approval system. So what the majority of the corrupt don't approve you remember god loves us all equally, people are true animals
