yurts and light

[Bender of camp charlie the uniocorn BM]

At BM there are times when light inside the yurt would be useful. Day
and night. In thinking about how to let in light and not the heat I
came up with two ideas.

Deck Prisms. They are basically big diamond shaped chunks of glass or
poly that bring light in from above the deck to below deck. Same
principal with yurts. I am unsure if this light would add heat into
the yurt.

This year I was thinking of just buying a dozen or so of those cheap
solar path lights. Hole cutting into the roof area and tightly
installing a few of them into the insulation boards. This brings in
light at night. I had six in my tent and they really never gave off
enough light to keep me awake. After a week at BM really nothing can
keep you awake when you are set to crash.

Rather mood lighting.

Any other ideas please post.

homemade chisel than i can with a plasma cutter.

I got some of the bottle bulbs in my H12 OBS yurt, and they work very well. I currently have 4, all in standard 0,5-0,7Liter bottles, intending to add 5 more.

    The light is sufficient for being in the yurt, and doesn't disturb sleeping during the day (it's not that strong).

Of course, it doesn't give any light at night.

There is a company that makes a 27W solar panel that folds up to about the size of a briefcase. They can be hooked together to produce more power. You can run a small evap cooler from one, and a CFL or LED light from another.

Last burn we just bought two strings of solar powered christmas lights
from amazon. You could run them through a seam in the tape or through
a hole that has been cut out for a window. Then tape the tiny solar
panel up on the southish side of the roof.

They seemed know how long to last - going on at sunset, and going off
before we came home for the night to sleep (somewhere between 3 and
7am).

We ran blue (to complement our amber colored led candles), but i'm
sure other colors would produce more (or less) light. Pretty cheap at
around $10-$15 per, and you can always turn them off at the solar
panel box if you need darkness.

You could cut one or more square or rectangular portholes in the roof and tape bubblewrap to the outside. Keep the cutout section, tape it back into the porthole along one edge, and poke two holes into the other edge so you can thread through a loop of twine to use as a handle. They you can open or close the window in daytime. At night a couple inexpensive battery powered LED lanterns work well for lighting the inside.

For daytime lighting in our dome yurt we found some small HEPA filters (with frames) and cut square holes in the middle of two wall/roof panels the same size as the filters. We popped the filters in the holes when we wanted light (and filtered air).  When it was too dusty, or early in the morning, we shoved the cut-out pieces of panels back in the holes (make sure you label them, which panel and in/out sides) to seal the panel back up. This kept the yurt cool until about 10am.  

 

Problems: 1. we waited to cut holes = messy moop inside the yurt on the playa. 2. putting the filters/cut pieces into and out of the holes made even more of a mess every time.  Possible solutions: 1. precut holes at home 2. find a way to cut the holes just a teensy bit bigger than the filters so the inner/cut edges can be sealed with tape for a more snug fit and no mess (would need to be really snug just in case it rains). Suggestions: make these cut-out holes in more panels to allow for more airflow (multiple directions of windflow and upper/lower air flow).  Also, as someone else suggested, craft some clear windows in frames.  Ideally, each hole cut would have three alternatives for filling: original cut panel piece, HEPA filter or a clear panel of some sort and the ability to seal them tight enough to keep out dust and rain.  Of course, in good weather (like last year) you can just leave the holes open and let that gorgeous blue sky shine in...

 

At night we had multiple strings of LED lights taped to the ceiling with gaffers tape, running on rechargeable batteries charged by the sun each day.  These only stayed up for a while until we had to pull them down, spray the inside walls with vinegar (to remove the dust) and re-tape/hang them again.  Did this twice while we were there during the week.  They were white lights and were ample to see at night because of the silver reflective surface inside the yurt. For times when we needed more light we used a small solar-powered lantern we left on our doorstep to recharge during the day or our hand-winding flashlight.

I think I can get a couple or three dozen of these to Burning Man for free if somebody will cover the shipping. I helped set up the deal that put those solar lights into Pakistan, and I'd love to get some of them (or another very similar light) to Burning Man. They go very nicely with the hexayurt - you hang them in the center of the unit a couple of feet down from the apex, pointing up so that the reflected ambient light fills the entire space with a sort of moonlight glow. It's a very beautiful, magical kind of environment.

So assuming I can get my hands on the samples, how are we going to get them from London to Burning Man, and how are we going to distribute them once they're on site?

vinay-

any idea what the total shipping weight might be?

i'm sure we can help with the cost if there is someone on the shipping end who can handle actual shipping, customs forms, etc.

we can provide a ups or fed ex account, or simply reimburse whomever handles this on the shipper end

as to distribution, not a clue, but maybe this is something that julie danger could assist with

please let us know the best way to proceed

regards,

total shipping weight - it's about 200 grams a light, I'll get some and weight to be sure, say three dozen lights. Yes, sending them to Julie's a great idea.

You guys *rock* have I mentioned this?

By the way, how are tape sales relative to last year? I'm wondering if that's any indicator of how many units we're going to see on the playa this year...

Hello!

 

I wish I could build my yurt for BRC this year.. but again it will have to wait. In my yurt, I was planning to add this awesome idea for letting daylight in w/o power...

 

I learned about this solar tube used in shanty towns and thought it would be perfect for the hexayurt! Please try it and let me know how it worked for you. :)

Google around for Solar soda bottle skylight for many variations and uses.

Hi Sonja and all the rest of ya'yurters,

I have the chlorinated "light bottles" as the only lightsource in my plywood H12. It works wonders. Prior to installing them, I had holes in the roof just covered my 6mil plastic, and with the bottles it went from "less dark but still like a cave" to "OMG it's morning".

    I have 9 0.5 liter bottles, because I happened to have a drill right that size. If I was to redo it, I'd have fewer but bigger holes, fit for 1.5/2L bottles, as in the instructions for the bottle lights.

Of course, I also got electricity for when it's night-time, so I don't need any other "solar solution" than sun-access. That's a whole other subject.

Enjoy the playa everyone, and make a great day,

M

Hi.  I've read about the Liter of light but do you have specific directions on production?  I noticed they seem to tape the top of the bottles and then cover them with some kind of paste.  I assume this is to keep the heated water from blowing the off.  Did you just tape the bottles into the holes you made, once you got to the Playa? Thanks Julie

Basically, it's two capfuls of bleach and water in the bottle, with a flange to keep the bottle from sliding through. http://www.instructables.com/id/How-to-build-a-SOLAR-BOTTLE-BULB/
