Any chance you could link to the heating elements?

Thank You!!! that was great!!!!

Thank kiu

What's the smallest panel you can use?

Awesome, very good product, tks bro

Atmospheric means condensing from the air to make water ! You using water to condense to distill water . Your ads should read how to distilled water ! 😂😂😂😂😂

Why do some solar cells have 1 and others more than one bus bar on them?

Thanks brother keep em coming it's boiling here in SC.lol

HI This is off Topic.. Did you ever make a DVD SOLAR Panel? I did everything down to the T from the Hidden Technology channel video titled.. This Homemade SOLAR Panel works on moonlight.. I didn't get any readings from volt meter I sanded 5 different types of DVD new and used and used nickel strip and tried foil for connecting.. Still nothing.. not sure if I didn't sand down far enough or another hoax

Hi, is it possible to run on 5V DC?

To be honest, I really want to buy a dryer but instead of heating up I just want it to blow air.

If the pipes were bigger would they be producing bigger condensed droplets? So if we scaled up do we need to scale everything up I.e. add more water or just enough to keep a continuous flow

My main question is are we losing the cool water we’re flowing through every certain amount do to other factors? And if are, are we atleast producing more than we’re using. Say if this were scaled up.

need to look into making one of these

Try some copper tube instead of PEX.

I did this, but with a twist. Note: I used crimp-on PEX connectors. I live in the Midwest and Shark-bite fittings retain enough water even after "draining" to burst the fitting during a hard freeze. The twist is: I installed a 12-volt solar operated inline circulation pump connected to a 12- to 18- volt PV solar panel. The pump is inside above my hot water storage tank, connected to a loop from a tee fitting on the cold inlet, running through the collector, then returning through the hot line atop the tank. During use, cold water is drawn from the dip tube. When there's enough sunshine to run the motor, there's enough to heat the water. I've used FREE solar energy to heat water for the past 45 years.

HELLO DESERT, I NEED YOUR HELP! I'm building my cooler based on the design of your "deluxe" version, but I got stuck after I saw this video, especially because I'm using the same 8 row radiator combined with a Seaflow 4" blower. Does the box fan performs better to cool an entire room or, with the same 8 row radiator, the air blower is still better? From what I see, the fan box version is only suitable to stream some cool air to a target area, but no more than that, right? With the deluxe version you said that temperature of the room dropped by 2 degree. No more that? Because 2 degrees less does not help at all on summer. Thanks

This is only for folks that don’t have aircon unit(s). We get about 8L per 5 hours runtime in spain

hey, I followed this guide. I got a cooler for the ice instead and drilled some holes for the tubes. The blocks of ice I put in melt in less than 1-2 hours though, do you have any tips on reducing how fast they melt? Thanks a lot

I think a used window AC might cost less and work better ...but I guess in a jam this will work ...

How long can yhis tun a fridge?

Tbh, so many of the Solar ovens/cookers out there are over complicated and inefficient, which is why I developed an easy vacuum insulated system (not tubes, and I can put a pot in there). I still gave a like because it is a good design for these more traditional type solar ovens/cookers.

I see nowhere on here do I see what it actually cost you to build. Including what you might think you’d get paid per hour to build it.

Awesome, man. What square footage will this cool?

Great idea. Sounds loud. Is it?

8:53

Is there little to no sand blowing from the fan? This is a great idea Peace N Love

of course it gives heat but what size of room you can heat up?measure the room temp

Where did you get your solar panel?

Call me impressed.. the simpler the better. Using $10 drill pushed it up solid 9.9 points . I see a cool seat ahead on 99degree deck

Yesterday i made it to 90% , but my fan is not the fan you are using . So when i tried that out , the air was not blowing out of cooler it was very low speed i guess , can you tell me which fan you are using so i can use the same and see if its works . Otherwise my all money will get wasted . Help me in this regard

What did you use for th liner? Yoj should have daid and described the inner liner.

I don't have pvc pipe, but i do have flexible dryer conduit. I figure it would do the same.

Good god coiling 100' of this correctly in a rectangular frame has been a nightmare. So hard to work with. Going to go with a 3x3 square and use that dowel / hook method

It is harder to build, but if you use this system, but hang it on the ceiling, so the cool air 'falls on your bed'? You might even use a normal ceiling fan, but then you need a bracket for the radiator or maybe you could make a spiral from some copper tubing which you use as the radiator. It would need some long hoses to feed the radiator of course with water, but I think it would feel better if the cool air comes from above, than from the side. Because if it comes from the side the air only hits you on one side of the bed and your body. What do you think?

Where would that styrofoam liner come from?

Dude, you are awesome. BTW, Robert Murray Smith did a shootout to you on an idea you had and incorporated into one if his works. He gave you great credit. We all love and thank you for your work.

Davos, WEF will kick you out sand, water, stoves

wow, have you thought of making a convection oven, perhaps we could bake some bread at 150 C

The concept will work only for an hour or two, until the water gradually raises to the ambient temp. A better approach is to use evaporative cooling(a mister and a fan) to cool the coil, and transport the high humidity air out to exhaust, all the while -pumping- recirculating air through the coil. But the coil need to be large diameter though. This approach will get the best out of evaporative cooling, while preventing humidity from reaching uncomfortable levels(due to enclosed space). Water that is lost as humidity still need to be replenished(manually or through a pump plumbed to a tap), but at a relaxed interval(depending on the insulated reservoir capacity).

Those do not work well or at all in humid conditions. Lower the relative humidity (dew point perhaps) the cooler it will become. Avoid setting them in the ground or any other heat sinking surface. And keep out of the sun! Also, the Zeer pot was invented in North Africa some 2,000 years ago.

you need an outside...erm... 'water feature". actually, an evaporative cooler... fountain, little boy peeing, lady emptying her wine cask, stack of bricks with water trickled over... whatever. large thermal mass, with the evaporation taking place outside, with the then cool, ideally always 4C water is pumped through the radiator... water, if allowed to do so, will naturally fall to 4C from evaporation... and using large intercoolers instead of radiators, you can have far more flow, without the invariable pumping losses as theyre so free-flowing... its easier to move water through large 2" pipes than through 1/2"... lot more surface area to exchange heat through as well... of course, you can always throw auto radiators with the included fan on there.... most of them are fairly simple speed controlled 12V units... solar panel and battery...

@DESERTSUN2 How does the radiator and work with just a large body of ambient water? Would it bring air temp much lower due to thermal mass? Wondering if you had20 gallons of water, pipe it thru a radiator and fan thru the radiator. Would the fan work better. just want to know if ice is truly necessary

If you added a dollar tree pool noodle to the intake hose and put the water in something insulated it could possibly be more efficient. Either way it's an awesome idea.

The straight copper serpentine heater could be made quicker and easier with 180° copper return fittings, they save lots of cutting and they cut the number of solder joints in half. You could also buy a 1/2" OD(3/8" ID) tube bender and make 180° bends yourself and then just solder the two ends. The pipe bender will give you a tighter radius of only 1.5" so the straight pipes are closer together. This type of setup could also be done with two layers of copper pipe offset half the distance of the return bend for more heating surface area.

I saw a similar video where the guy was pumping cold water out of his well to a heat exchanger and back into the well and it worked fantastic. I live in a northern state and the groundwater temp from our 680 ft deep well is 40°F year round. It would be perfect for a chiller system instead of air con. I bet you could take an old air handler and pump chilled water through the refrigerant coil lines and have very good results and it would also be connected to the thermostat so you could adjust the temp.

Very nice job. Thanks for sharing! I am thinking of fabing one for my tent camping ⛺️. It stays hot all night long in South Carolina.

What size room did this cool and how long did it take to reduce the temperature? Looks like a great system.

You need collect condenced water. Lot of it. I did that once. One way is cut fridge box off and use system to cooling.

1. How big a room can it warm up? 2. For how long?
