Drinking Water Condenser

Does anyone have any plans or ideas for a DIY drinking water condenser? Something that can make water from the air would be fantastic, especially as climate change starts to have more and more of an impact on the availability of clean water. Electric powered should be fine, directly solar powered might be more difficult. Any thoughts?

Help with multistage balloon-tipped water missile

I'm designing the perfect water weapon of mass soakage-the super water missile, and I'm shifting my attention to multistage water rocket thrust systems. My finished product will hopefully be able to reach high altitudes, acheive moderate horizontal distance, and either drop many water balloons over a specified target area, or be tipped with a very large water balloon for a "wet impact" (very wet). I don't know how multistage water rockets operate though, and there are no instructables on how to build them. I searched Google, and all I got was pictures. No DIY's, how-to's, or tutorials. Could anyone tell me (or better yet-show me) how to make a multistage water rocket-or at least how they operate?

The science behind this self watering system for plants

Hi, I was watching a video for a self watering system for plants (link below), and was wondering what the science behind it is called. I also had a problem where no water came out of the bottle because the hole I made at the bottom was too small. As soon as I unscrewed the cap a little, the water came gushing out. https://www.youtube.com/watch?v=Ffe7JfYyBFE Thanks :)

water pump idea

I hypothesise that when is heat applied to a suitable sealed vessel, filled with water, and having a pipe into the base of the container below the water level, that when the water gets hot enough, it will exit the pipe under pressure. if anyone has any input or had experiance with this kind of a thing or knows of a device which works in the same or similar manner, i would like to hear from you.  i though it could be a way of moving water with no moving parts or access to electricity, motors etc. thank Kim.C.S.B

Water valve on/off control

Need some help! I need to know what to buy. I need to control water flow with an electric water valve to open when the water temp reaches 65 degrees and shut off at 55 degrees. From the valve, thermometer, etc., what do I need to buy and how can I wire it? I know it’s the same concept as a HAVAC thermostat in your home, but I don’t know how to wire it to a relay for the valve.

Too Short for an Instructable- free water

A friend showed me this trick at Safeway. If you are thirsty, but either 1) Don't have money on you or 2) Don't want to buy a whole bottle just for a few sips, most food stores are required to give free water to anyone who asks. There will be no signs advertising this fact. Simply walk up to the counter (we did this at a small Starbucks stand by the bakery) and politely ask for a drink of water. My friend received a clear plastic cup filled with water and ice, no charge. Then I walked up and bought a Dr. Pepper, not free of charge.

I need help finding a mini water pump with DC motor

I've been trying aliexpress, Amazon, ebay, etc., but I'm not sure what to look for really. I just need a water pump with an attached low voltage DC motor that can shoot a jet of water. Everything I see looks like low flow stuff for fish tanks etc... perhaps I'm not using the right search criteria or am not able to recognize the right motor and pump when I see it.

DIY water jet engine?

Hello. Me and couple of my local DIY buddies are also big fans of fishing. Because we are all students and can't drop 1K+ on normal outboard motor for our tiny aluminum boat, we are thinking on making our own. What we have here is a 200cc lawnmower engine. Because we don't wanna get into business of making our own gears we are looking for ways to implement water jet system. The problem is we just can't figure out what is gonna do a good job of being our turbine. Any suggestions? Does anyone know if the intake half of automotive turbocharger is gonna for pumping water?

Ratings?

I was just updating the group today, and I noticed that this group has been here for at least six months, and this group has no ratings! I would rate it myself, but I can't rate my own group..... If you were to search for other water war related groups, how many would you find? I checked recently, and unless somebody decided to make one, I found one result-The Water Warrior Group. If this is the only water war related group on all of instructables, then don't you think we could use some stars? If you happen to read this, add a rating! It'll make you feel better about your life, and it'll certainly make me feel better about mine!

clean and reuse washwater

I want to clean and reuse my washing machine water to wash clothes.  The system must be #1 cheap to build(off the shelf parts), #2 cheap to use(wasting power to save water is stupid). I am thinking, an easily accessed fine mesh lint trap. A second stage to remove chemicals (sand?charcoal?) and a third to kill any buggies (UV light?). I will also need to address which products are best to use for this system. And of course a valve too return to the "normal" system for some occaisions. Thanks for any input . nursenary

Plumbing Help

Help! We just moved into a new house and the water pressure seemed pretty high, especially at the bathroom sink (it sprays everywhere when turned on full).  I tested the pressure at an exterior hose bib and it measured at 81 psi.  It also measured at 79 psi at the cold water supply valve for the washing machine.  I sent the pictures listed here to my father-in-law, who seems to believe that I can adjust the pressure with the current plumbing system.  I looked everywhere for a pressure regulator in the line, but couldn't find one.  The only thing I can think of is that he believes the gray valve above the meter is a glob valve and can be used to throttle down the pressure.   Any help would be appreciated!

Pumping Water From Basement To Roof

I have a 50 gallon water tank in the basement and a solar tank on the roof. The roof tank is 35 ft above the basement tank and the top of the basement tank is connected at the bottom of the roof tank with 1/2 inch Pex with valves. Is there a simple way of pumping the basement water to the empty roof tank. Unfortunately I can't use city water pressure to force the basement water up to the roof. I am trying to transfer the basement water to the roof leaving the basement tank empty.

Spain Turning Into Desert as Water Wars Begin

Parts of Spain are feeling the pinch of too many people going after too little water. Some of the land is drying out after water-thirsty resorts and corn farms in the arid land guzzle it all up and leave nothing behind. About the only thriving part is the black market which is charging ever higher prices.Where I live in Oakland we're getting phone calls from the water utility to cut back on water use and are facing higher prices ourselves. People could even face penalties for excessive watering of gardens. Makes me feel OK for letting most of our plants shrivel up and die after all. Water Shortage in Spain

Electronic water level gauge for well

I have a 32m deep, 95cm diameter well, that is covered with two heavy concrete covers. The water depth is about 20m down from the surface. I cannot easily access the well to sound the depth or visually check the water level. I would like to build an electronic water level gauge that will tell me the amount of water in the well. I can then regulate watering accordingly. It was suggested to me that I use a washing machine pressure transducer but I have no idea of the circuit required. A refined solution would send data to my PC !!!! I have 240v AC supply to the well pump. Any ideas? Steve

Pumping Water in the Arctic!

As a small background to the project I am working on: I am currently doing my Masters of Architecture in Copenhagen, and we are designing devices to bring on our expedition to the North Pole, and I am harnessing salt water to pump through salt water batteries. My question is then: What kind of pump do I need to pump water up 2 meters? I don't need much water coming up at once, just needs to be constant. I am also looking for the most energy efficient way of doing this, any know of something? Any help is much appreciated! :) Thanks, AD

Animating Water Bottle Recycling Rates

Here's a neat animation of water bottle recycling rates....bottled water (in all its flavors) has become one of the most consumed, yet least recycled beverages. For example, it is estimated that in 2005 alone approximately 30 billion plastic water bottles were purchased, with only about 12% recycled (in part due to out-dated deposit laws). The remaining 25 billion bottles were either landfilled, littered or incinerated. Obviously that's a lot of bottles, but statistics involving "billions of bottles per year" can be difficult to put into perspective.

How to make water from excessively humid air (using little energy) . Any ideas?

I was thinking of making some sort of machine that uses cooling coils to condense water from the air, seeing as to how humid it has been lately, but I want to do it using less energy than a dehumidifier that's on all the time and have it be more rugged so I can put it outside and maybe use it to water the garden.

I've been trying to do some research before purchasing a shower water softener, as our water is unbearably hard. It drys out the skin and promotes clogged pores.

I'd appreciate it if anyone could give me the quick and dirty version of what i need to look for in one of these things. Thank you!

Low Cost Low Tech Ozone Bubbler

Clean water is becoming scarce and chlorine is a dangerous substance to be hauling around in the Third World. The dirty secret in water processing is that ozone works just as well as chlorine. How about coming up with a small handheld device which could sanitize small amounts of water using the local atmoshere by turning o2 into o3.   I'm thinking aquarium pump to begin with.
