Re: [hexayurt] Re: Video test of Buckminster Fuller's Cooling Effect
Hi Ken, I had thought of doing it with a drip tank, yes. That definitely seems like the simplest passive setup. I bet we could figure out something else though. My main goal with a passive setup would be to do away with fan noise. >From that perspective a battery or solar powered pump would probably be a fine addition, because depending on the model of pump it could be quite quiet. I do like the elegance of totally passive systems though. I'll roll it around in the head for a bit.

[hexayurt] Re: Video test of Buckminster Fuller's Cooling Effect
Jack, I'm intrigued by this. Am wondering how you envision establishing a passive swamp cooler setup? That is, no pump. I understand how you will move the air (via heat convection with the solar chimney). But how will you move the water to keep the the pads moist? Or would this require refilling a tank with a drip line every few hours?

Re: [hexayurt] Re: Video test of Buckminster Fuller's Cooling Effect
A lot of national parks use the solar chimney for ventilation of outhouse style toilets. It is very effective. They use about a 9 inch diameter PVC pipe that goes up the entire side of the building and several feet above, so it gets a good amount of sun exposure. I think you could do it with smaller pipe but surface area is definitely important. You could use that to create the vacuum and pair it with a swamp cooler type setup at the intake vent, thus having a passive cooling system that operates most strongly when it is most needed. That is, when the sun is shining. On Aug 26, 2011 8:38 PM, "ken winston caine" wrote: -- You received this message because you are subscribed to the Google Groups "hexayurt" group.

The black pipe concept is similar to what is known in passive-solar building as a "solar chimney." Google that term for some more inspiration.

Re: [hexayurt] Re: Video test of Buckminster Fuller's Cooling Effect
First off I am also a skeptic on this version of the cooling effect...though the conditions set in the video did not match the description of how the effect works. Anyway, I had an idea for a hexayurt passive cooling system that I designed, and started but did not get to try last year (and won't this year either). Here's the idea: Put a black plastic PVC pipe in the center of the roof. The sun will heat the pipe causing the hot air inside the pipe to rise, consequently drafting cooler air in the bottom, through the spaces around the door flap. To further cool the air coming in, you could build the hexayurt directly next to an evap pond you are using to deal with your shower water. To further cool you could place a length of copper tubing into the evap pond, with one open end just pointing into the air and the other open end inside the hexayurt. The sun heats the black PVC which causes a strong updraft. The updraft pulls air in through the copper pipe. The air moving through the pipe cools down. The copper pipe is laying in the evap pond so the evap effect is further cooling the air. Does this system sound like it would work?

There is also the small roof turbine: http://youtu.be/nWsVl1t5NQ0 Now, I'd like to put one of these on top and see how my smoke flows through it. Problems with these? The bearings are cheap and freeze up. They also make a lot of noise all night keeping you awake. SoI'm still into an active fan, especially if you combine it with mini evap coolers at all bottom vents. You want constant airflow to get constant cooling. The wind won't help you with that. -- You received this message because you are subscribed to the Google Groups "hexayurt" group. To post to this group, send email to hexayurt@googlegroups.com.

Now imagine a wide, black painted "chamber" in the pipe on top. There would be more surface area to collect heat and more air being heated. You could do it easily with different size pipe and reducers. Although, quality fans can be really reliable. And will actually move much more air. 12v powered is easy to do. Even directly connected to solar panels with no battery. Sun comes out, fan speeds up. Now, if you build from earth blocks, you don't need fans or any of this trickery. But earth building is labor intensive and not portable. Plus, some places don't have suitable dirt. So...I'm going for simple active systems with replaceable modular parts. The design shape of the building helps you use the least amount of active technology. -- You received this message because you are subscribed to the Google Groups "hexayurt" group.

[hexayurt] Re: Video test of Buckminster Fuller's Cooling Effect
You could run a fluid dynamics simulation on a hexayurt. Just enter in the parameters. Takes a beefy computer though. There's a project for bored university guys! It could settle it in "an instant". As "Laurie" stated in her direct letter to BF " The effect you are thinking of is the Joule-Thompson Effect, but even that does not apply here as the inside-dome and outside-dome pressures are equal, therefore no inside-outside temperature difference can exist due to insignificant flow rates. " No temp difference in the air can occur when the air pressure is identical Inside and outside. And for all intents and purposes, they would be *completely* identical. Unless you have 200mph air rushing around somewhere inside/outside. Actually I think it's like this (she was talking backwards): Massive airflow-->Causes pressure difference-->Temperature change Take two sensitive barometers and put them inside and outside a structure How the hell would you make *any* kind of massive pressure change? With a tornado or hurricane? Think about it. And further, *why* would you want to change the pressure that much just to cool yer ass off? This leads into nonsense territory like any good "Fool's Errand". Fuller was not some infallible god. He had *many* project failures. He noticed some odd airflow just like Vinay, but never really bothered to document it. Although, he did fabricate that entire scenario in his book. Why? Who knows. And personally I don't care ;) I believe Mythbusters would not let this one through the filter. One look by anyone who has taken a course on this stuff would spot it instantly.

Re: [hexayurt] Re: Video test of Buckminster Fuller's Cooling Effect
Fluid dynamics doesn't scale. I've seen *very* odd effects around huge domes at Burning Man - 60ft diameter, covered with a cargo chute, chimney-style airflow up the sides of the dome for substantial cooling, but no downdraft. But still very, very weird. Perhaps we should get Mythbusters involved, god knows they've got the budget.

[hexayurt] Re: Video test of Buckminster Fuller's Cooling Effect
Not gonna happen. These conditions probably cannot be met in "real life" anywhere. The proof would have been in documentation. If he did any at all. His only personal mention of this cooling (available on the net and book form) is rife with silly talk. Laurie pointed this out. There would need to be a *huge* pressure differential and ultra high air velocity. Imagine the nozzle tip of a blow gun hooked to an air compressor. You can get cooling that way. And that's probably it. Fuller was great at some things. Concepts. Delivery was another story. #5 was explained by Ken and in Fuller's books. Google "World Game Bucky Fuller" It's dead, Jim. If anyone doubts, I'd love to see a video response. Ain't gonna happen (I predict complete apathy!) Now, for those that don't want to get hands dirtyget to clicky clicky on the keyboards and do a *proper* computer simulation. Cause this is how (some) roll in the 21st century.
