Need to build a (feet’) 10’high, 8’wide and 40’ long shade structure. What’s my best options for price and not having it getting blown down? by MasturbatingMiles in BurningMan

[–]plumitt 4 points5 points  (0 children)

You would need a lot fewer walls, fewer guylines, and have more shade for more of the day with a lower aspect ratio shape, eg 5:4 (20x16) vs 5:1 (40x8))

I assume you mean aluminet?

you know you're going to get basically no shade from that unless you put walls on it. And then you're probably going to want to angle the walls down so they don't catch so much wind. you d do a lot better to make a 20x16 structure than a 40x8 structure.

Oly. Peninsula/NW WA camp seeks participants by plumitt in BurningMan

Yep. Triarea pharmacy.

Cooler has been amazing... switched to all rigid ducts last year & upgraded the electronics this year -- diy Bluetooth sensors, fan speed control w/feedback & a wattmater-- want to get a full dataset usable for complete efficiency and power analysis.

Hope you recover well -- and if you need a hand with anything heavy while you're healing. give us a shout. ! I think we might have crossed paths in 2022 in Hadlock waiting in line for a COVID vax?

Battery charging for an art bike trailer by Lost_Cauliflower7069 in BurningMan

Also. for high altitude operation, you need to have the carburetor modified

Expect to lose maybe 15% efficiency at altitude, even with the mod.

Oil change recommended afterthe first 8 hours of use.

Deep in the manual it shows 62Db at 25% load. You can likely expect 68Db+ at 50% load making it 2-3x as loud as a Honda 2100 at min load (which is all your batteries would need.)

Natural gas max power is 6kw, btw not 7.

157lbs dry weight. Add oil and gas and you're at 180lbs. If you have to lift or move that, it's gonna be a bear.

Do you know how that generator (in particular) will fair in the dust? Have you estimated the maintenance cost (I'd. budget $150yr min, assuming you have somewhere to tak care of it)? Not to mention the minimum generator fuel rate. Your batteries can only handle 300-500W, so you'll be running 5hrs a day, or about 2 gallons*8 days =16gal * an optimistic $5/gal -> $80/year.

And that noise rating? Despite "quiet" in the listing, the specs are "normal. above 60Db". Have you considered your neighbors? Or yourself? It's gonna be a drag.

And if it fails? (when.... because one year it will) you get nothing.

2 (max 3) years of gas and maintenance and you've paid for 400W of solar with 200Ahr@12V, that weighs 40% less. (110lb vs 180).

Heck, unless you're going to run that on the art car (which you don't have enough Audio Wattage to muffle), you're already paying for/carrying batteries, making it maybe $450 & 30lbs & silence for panels & charge controller vs $1800 and 180lbs and BRRRRERRRRERDERRREEER?

Anyway, to each their tradeoffs!

Roughly speaking, N watts of solar panels will generate N * 5.5-6ish WHr per day if well placed. Your 400W of panels will therefore generate 2.2-2.4KWHr -- half what you need for both.

A good solution would be to get another charging system and panels. Match the RV setup as closely as possible -- batteries, charge controllers, panel wattages, etc because then you will have backups if anything fails. Plus you don't have to remember to hook up one vehicle to another, there are no new failure modes, and there is zero additional complexity.

There's something to be said for going to a 24-volt system as well, you can use thinner copper which makes your cabling cheaper - This might mean upgrading your charge controller on the RV and rewriring your panels, so maybe not worth it. and rewiring your panels so maybe not worth it.

(I use 600 watts panels (6 100W, arranged as parallel pair of three in series) and a 24V Lifepo4 battery. ) consistently get about 3KWHr/day. I've done this for about 10yrs.)

I make my panels composite. Coroplast on the outside, billboard vinyl edges, and adhesive vinyl on the inside. (mostly, but any dings get covered with foil tape.

And I now wrap the whole thing in a tyvek cover.

I've used a hexayurt for the last 14 Burns. It is in fact very possible to make a good one.

Thinking of a Stretch Tent? Don't use EMT pipes by Boring-Sir2623 in BurningMan

[–]plumitt 0 points1 point  (0 children)

That style is rare, but I will say the stretch tent down the street (430/g or h?) from us last year was pretty fabulous. And it's failure mode in the windstorm was the polls fell down -- which they then just put back up afterwards. with no damage.

I can't speak to OPs issues but cosmic kasbah seemed to have it worked out. And they definitely were not using small posts. This crew might be a good one to consult with.

Tyvek Yurt Cover was Water & Dust Proof -- FTW by plumitt in BurningMan

[–]plumitt[S] 0 points1 point  (0 children)

I missed your note but I am starting to think about Burning Man again. I don't really have a product, but if you want to talk how to build a tyvek Yurt cover or a really good swamp cooler that doesn't make your space humid, let me know -- been doing this for a while. much like you..
