cooling your tent or van
You might get lucky on eBay, but at the moment, the Silicon Solar pump that FigJam found appears to be the best candidate. It's as cheap as the HF pump was, more powerful, and only uses 300 milliamps (0.3 amps), so even though it's not solar, you could run it from a 10w solar panel pretty easily, but since the fans usually have to run from a battery power source anyway, 0.3 amps is a pretty negligible power draw to add.skinnay wrote:has anyone found any other solar powered pumps similar to the HF pump mentioned before? I need to order my stuff asap! =[

I dont think so.
These pump move water but dont create presure.
I wasnt sure about this pump till I watched the vid and it looks like its pumping enough water high enough to do the job.
When he runs it with the hose on, it looks like 24".

yeah i just saw that and cant imagine it needing more water than that, i just ordered it!
all i need now is a 4" fan. if it really generates that much power i wonder if i can find a 6v fan and splice it onto that wire and run them both off the solar panel. that would be ideal =] and im only using it for a 4x6 tent

The pump body looks about the same as the HF one. Except the solar panel is enormous compared to the HF pump!
I've never run mine like that to see how high it pushes the water though.
Pump body size doesn't mean much, however. The HF pump is plenty powerful, and it looks like a housecat sitting next to a full size tiger, comparing it to the Silicon Solar pump.
$30 sucks, though. The $20 normal price, and the $13 sale price, for the HF pump was better. *sob*
Interesting, this one looks JUST like the HF pump, even the solar panel looks the same. But this model includes 5 batteries, so I guess it will run at night, too.
$40 + S&H, though.

I would reconsider that pad. The aspen pads are notorious for shedding bits of wood all over the place. MOOP-tastic. Not a big deal on your roof (but still a PITA to clean out when you change them out, annually, I think) but could be a problem on the playa. And do they bend nicely to fit in a bucket, or are you making a square cooler?skinnay wrote:also just ordered this as a cooling pad

)think it will bend around the bucket once its wet?
I have the swamp cooler completely operational and installed on my Toyota motorhome. I put aluminum foil covering the sunny side windows and put the cooler on low. The motorhome cabin went from 100 degrees to about 82 degrees. The pads are wet, but there is no water sprinkling in, so the pump seems just about right. When and if I get some more money, I'm going to look into some of this radiant barrier from Home Depot to make some more substantial window shades. http://www.homedepot.com/Building-Mater ... ogId=10053

4" is not a standard size.skinnay wrote:can anyone recommend a 4" 12volt fan? i need to order one today =]
The 120mm fans are ~4.75" and are readily available.
You can try to find 100mm fans, which are essentially 4", but I don't recall seeing those very often. 80xx and 120mm are the standard sizes for 12v computer fans.
I've seen 92mm fans, which are ~3.5".
But I would give serious consideration to trying to use standard 120mm fans if you can. The fan is the most crucial part of these coolers, and it took a lot of research to narrow the field down to the best candidates (like the Delta 4k fan or the Scythe Kaze 3k fans linked earlier in this thread).
I could probably rig a 120mm fan, its just that the duct i have already sent out to the playa is 4" =]kman wrote:4" is not a standard size.skinnay wrote:can anyone recommend a 4" 12volt fan? i need to order one today =]

I took Figjam's lead and used an old plastic bowl as a duct reducer, because I also had 4" ducting. I found a bowl that would cover the hole for my fan and sawed off the bottom of the bowl, screwed the top rim of the bowl to the lid of my bucket, then duct-taped my 4" ducting to the cut-off bottom of the bowl. Works great!skinnay wrote:I could probably rig a 120mm fan, its just that the duct i have already sent out to the playa is 4" =]kman wrote:4" is not a standard size.skinnay wrote:can anyone recommend a 4" 12volt fan? i need to order one today =]

I don't always trust silicone to hold with rough handling, which is why I screwed my bowl on. Just drill small holes through the rim of the bowl into the bucket lid, insert screws and nuts and tighten...zip ties also work, those magical little fasteners I love so much!
The bowl I found was almost perfectly proportioned for this use, kind of a tall, narrowish old tupperware bowl, going from about 6" to 4" on the bottom of it, so duct-tape worked awesome.

Next year I keep telling myself.I'm told speed controllers work by monkeying with the voltage, but you really want max output from these fans, so I wouldn't bother unless you can be sure you're getting the most out of them.skinnay wrote:yeah i was wondering if the fan will run a little under powered or if just completely shuts off =]
i guess we will find out
Also, there's a chance you'll want to fire up the cooler before things get too bright and hot, and while it'll work ok with residual moisture from the pump until things get going, without the fans, it's useless.
Best bet, if solar is your aim, is feed your battery with the solar panel. But run the cooler off the battery.
