Burning Man fallout: DIY portable camping PVC pipe evap air conditioner by graywolf.
What he built is a tube framed by PVC pipe with a Fantastic Endless Breeze fan at the top, a tub at the bottom, wrapped in cooler pad material, and a small 12v water pump to circulate water. The fan runs about $70 and the pump under $15. Tub, pipe, and pad are common hardware store items and should run well under $50 with the pads the most expensive item (e.g. Dial Mfg. 3072 Dura-Cool Pads at ~$16 ea).
If you are looking at the RV Motorhome Solar Battery 12-Volt Evaporative Swamp Air Conditioning Cooler that runs nearly $600 and want to see what evaporative cooling will do in your RV and what it takes, the DIY project makes for an inexpensive experimental apparatus. The most expensive part of the DIY swamp cooler is the Fan-Tastic Vent 01100WH Endless Breeze 12V Fan and that is a nice item to have even as just an RV table fan. The KEEDOX® DC30A-1230 12V DC 2 Phase CPU Cooling Car Brushless Water Pump Waterproof Submersible isn’t that expensive and appears to be a general purpose submersible 12v low volume water pump.

You might start the experimenting using the bathtub as a water reservoir. If you want automatic water filling, add a standard cooler float valve connected to the RV water supply. The two variables you will want to watch are water and power consumption. A few amps and a gallon or two of water per hour can make a big dent in an RV reserves over a hot afternoon.
Note: waste water is an attractive source for an evaporative cooler. The Burning Man have worked on that, too (see the Zyphers post on the evapotron). To use gray water for indoor cooling would require a water treatment plant to filter the waste water, apply a disinfectant, and, perhaps, a bit of perfume. — Possible but needs a bit of effort and care.
Power needs could be handled with a 100 watt or better solar system. The cost of that (think $4 per watt as a good guide) could be shared with other RV electrical power needs.
Another basic cooling device is shade. Awnings are a good start. Putting one of those 10×10 tent gazebos over the RV might also help. The problem with any of these is the afternoon Zephyrs as they can come with strong enough gusts at times to cause havoc with awnings and light structures.
Josh dug up Living in a Trailer by James Jones from the July 1952 edition of Holiday Magazine. Some things haven’t changed much in 63 years — some have.
“THE FIRST TIME you tow a house trailer you keep jerking the wheel to compensate for that crazy sway in the back end. It takes a long time to get enough used to it to ignore it. The first haul I ever made with mine—a trip that, although I didn’t know it then, turned out to be the first leg of a junket that would take me clear across the country and back and consume a year and a half—was to Memphis, Tennessee, from my home in Illinois. That’s about 400 miles, and it took me four days to make it. A year and a half later, on my way home from California, I hauled from Tucson, Arizona, to El Paso in one day. I had left a green-eared neophyte, and I was coming back a veteran. There is no pride in the world more rabid than that of a confirmed and dedicated trailerite. The next winter I took my trailer to Florida in four days, just about 1,200 miles.”

There is a page on Coffee in the Owner’s Guide that mentions the key ingredient but that ingredient is often overlooked in the obsession about beans and roasting and procedures and protocols. The science behind the perfect coffee is a report on research to find out just how the water can influence the taste of coffee. Here are some highlights from the report.
“Hendon used computational chemistry methods to look at how different compositions of water affect the extraction of six chemicals that contribute to the flavour of coffee, along with caffeine. The study, published in the Journal of Agricultural Food Chemistry, found that water composition can make a dramatic difference to the taste of coffee made from the same bean.
“Hendon explained: “Coffee beans contain hundreds of chemicals; the precise composition depends on the type of bean and how it is roasted. The flavour of the resulting coffee is determined by how much of these chemicals are extracted by the water, which is influenced by roast time, grind, temperature, pressure and brew time.
“We’ve found that the water composition is key to the proportions of sugars, starches, bases and acids extracted from a particular roast.”
“The coffee industry uses guidelines on the ideal water for coffee extraction from the Speciality Coffee Association of Europe (SCAE), which measures ionic conductivity to quantify the total dissolved solids, however the researchers found that it was the proportions of these ions that Maxwell Colonna-Dashwood, co-author on the paper, said: “Unfortunately most of the time you are limited by the source water available. Water from the tap varies regionally and from day to day depending on how much it rains affected the extraction and therefore the taste of the coffee.
It seems a bit of magnesium is better than sodium but they key to keep in mind is that this taste stuff is getting into the weeds. Both the water minerals and the coffee taste chemicals are in very small amounts and you don’t have a whole lot of control over them. In an RV, you deal with what you can get as you travel. Use the tastes you encounter as another local phenomena to enjoy like the scenery and other attractions.
There are those hot air type popcorn poppers but electricity and special gear aren’t necessarily a good thing in the RV. There are those Jiffy Pop (Jiffy Pop – Amazon Affiliate link) but you can also use an aluminum can and a few kernels. Eric Ravencraft describes how to turn an aluminum can into a DIY popcorn popper. Cut a flap for a popped corn deflecter and make a handfull with minimal hassle.
Some call them rats with PR. They don’t hibernate but they do hunker down when it’s cold or the weather is bad. Since they live off nuts with an occasional bird or bird egg and insects and whatnot, we probably ought to avoid putting out peanuts for the Blue Jays. Most of those peanuts get stashed and that means the squirrels can probably get a good meal robbing the Blue Jay stash. They are ‘cute’ but there are reasons people don’t like them around. GruntDoc has a nice picture about why the War on Squirrels got started. They chew on wires and other things.
A few years ago, some squirrels built a nest in the V of my B-Van V-8 engine. The smell of roasting sagebrush on the annual spring trip to the smog and lube center was quite nice but also quite a fire hazard. It took a bit of doing to get into the area to remove all the debris and clean things out. Now, its just another item on pre-trip the checkoff list.

Paul Michael has 25 Essential Tricks for Quick and Easy Cleaning over at WiseBread. These are mostly about uses of vinegar and baking soda and similar well tried recipes with a few techniques and hints. Examples:
“Use a tube sock on your hand, soaked in warm water, to wash your blinds. You can do both sides at once and balance the blind.”
“Simple dryer sheets, like Bounce, rubbed onto your baseboards will clean them up a treat. And as a bonus side effect, they coat them in a way that repels dust and pet hair.”
“Repair Hardwood Floor Scratches – All you need is a walnut. By rubbing a walnut into the shallow scratches, their natural oils help hide the flaw. It’s an age-old carpenter’s trick.”
It’s always handy to keep a list like this easy to find – sometimes it might just make life a bit easier, a bit cleaner, and better smelling!
For books on the subject, see Household cleaning recipes on Amazon (affiliate link). Many have Kindle editions so you can take them along without cluttering your RV!
The University of California Press has made 700 books available for reading free of charge. OpenCulture has the story.
“The University of California Press e-books collection holds books published by UCP (and a select few printed by other academic presses) between 1982-2004. The general public currently has access to 770 books through this initiative. The collection is dynamic, with new titles being added over time.”
The University of Chicago Press also provides some free material.
The OpenCulture page also has a number of links to other resouces that provide free media including eBooks, audio books, and movies.
If you have a Kindle reader, check out dailyfreebooks for thousands of free eBooks including promotional copies as well as copyright expired material.
Of course, don’t forget Project Gutenberg, the “first producer of free ebooks” based on volunteer efforts.
Then there is the local library. Did you know many loan books for eBook readers? For example, you can find a book at the Washoe County Library website and it will not only tell you which branch has the book available or allow you to place a hold on the book, it will also tell you if the book is available in the electronic edition. To help you out, there are even workshops such as the one at the North Valleys Library branch on January 18.
What is nice about the electronics media revolution is that you can haul around significant personal libraries and not burden your RV. Thousands of books or movies will fit in a typical backup drive or eBook reader or tablet.
Eugene Volokh reports that “Today’s Morris v. U.S. Army Corps of Engineers (D. Idaho Jan. 10, 2014) strikes down an Army Corps of Engineers regulation barring possession of loaded guns in recreation areas surrounding Corps dams.” In this case, a tent was considered akin to a home. Second amendment rights are protected in homes.
“The court also holds that the Second Amendment protects the right to carry guns as well as to possess them at homes, so that the regulation is unconstitutional even as to carrying outside tents. And the court rejects the argument that the government may restrict such gun possession and carrying on the grounds that the government owns the property, and has no obligation to open the property to the public in the first place.”
An RV is also “akin to a home” so a firearm you have in it should fall under the same judgment.
It used to be that having a firearm handy for protection while camping was no big deal. The comments to Volokh’s post show how this has changed. There is still a need in the wilds for protection and self defense but some folks think there is a danger from firearms that outweighs this need. Sometimes that thinking is so strong it results in court cases. The courts are a bit confused which is why Volokh warns that “It’s not clear how the opinion will fare on appeal, but the case should be interesting to watch.”
Whatever your opinion, if you do have firearms with you on your RV experience, make sure you maintain your shooting skills, keep up to date with laws and regulations where you travel, maintain the equipment in good condition, and store it properly for travel.
lifehacker notes a video about making watermelon smoothies with just a drill, a coat hanger, and, of course, the watermelon.
You may have a cordless drill driver for the stablizer jacks on your trailer and a coat hanger or other stiff wire isn’t that difficult to find. All you need to do is to cut a hole in the watermelon to allow you to get the wire bent into a beater shape inside. Then use the drill to blend the insides. Finally, fix a spout to poor out the smoothies. (food safe rated coat hangers, anyone?)
“the whole process takes seconds and leaves no messy cleanup behind. Just watch out for the seeds in that pulpy watermelon puree you’re about to enjoy. If you want to amp up the flavor a little bit, you could probably pour a little something into the watermelon after you’ve pulled the drill back out”
I wonder if it works and tastes as good as it sounds easy to do.
The fire season is looking towards a season change to winter. Fires and winds can make a difference in your travel plans. A couple of websites that provide useful information are from ESRI and HINT.FM
ESRI, a company that develops geographic information systems (GIS) has a public information map that shows the database of wildland fires, winds, and air quality alerts. Click on a marker and you get a popup with additional information.
The wind map is a personal art project. It shows wind data from the National Digital Forecast Database for the continental U.S. The winds are flowing lines whose intensity indicates the winds speed. If you are looking for a synoptic overview of what the winds on the continent are doing, this work of art can be fascinating.

If you unhitch and remove the ball mount from your tow vehicle, you’ve got an empty receiver that makes a solid mounting point. One use for that is a bit expensive but looks interesting (Amazon affiliate link) for those who like hammocks. – Green Eggs and Hammocks HamX2Go Trailer Hitch Hammock Chair Stand
Another option is a flagpole mount. The Camco 51611 Hitch Mount Flagpole Holder is about a tenth the cost of the hammock but you’d need to add your own flag pole and flag.
The problem with leaving the hitch ball mount assembly or a hammock or a flag pole attached to your tow vehicle is that the vehicle tends to become a part of the camp rather than an errands running or touring accessory.
The Burners have a rather severe problem when it comes to waste disposal. RV’s are very popular out on the playa but most don’t have waste tanks that will handle a full week’s worth of washing. Evaporative ponds for waste wash water have been superceded and newer technologies developed. The Gray-B-Gon is a wind powered device that fits in well with the Burning Man ethos. Flying Saucer evaporation also works well but uses a pump. The term ‘evapotron’ has been appropriated to name these devices and a web site put up to describe the devices – see evapotrons.
These ‘evapotrons’ are active devices that wet a tulle fabric or burlap cloth or something similar to promote evaporation. Besides the mechanics, there are two issues that are worth considering in normal RV practice. These are filtration and disinfecting. Oasis design has good discussion on Common grey water mistakes about these issues. Some more advanced efforts at treating waste wash water can make it somewhat acceptable for cooling devices (wikipedia). It is probably a better (safer) bet to put mechanical art on top of the RV to evaporate the waste. It appears that even a modest system can take care of ten gallons or more per day at Black Rock City.
It used to be that you could let RV wash water waste drain directly to plant covered absorbent soil away from any pond or stream and any traffic or use. That was reasonably safe. Most camping places prohibit such practice these days. There are some creative and portable solutions available if you need to safely handle waste wash water and an RV dump isn’t handy.
The U.S. is one of the very few countries to make a monument out of an embarrassment without outside provocation. The park service says it is One Camp, Ten Thousand Lives; One Camp, Ten Thousand Stories. Manzanar National Historic Site is 9 miles north of Lone Pine, CA.

Get a glimpse of the psyche of the American people just after the Pearl Harbor attack. Keep in mind that modern ideas of ethnicity, nationality, and race were a luxury back then. Think about things that don’t change about people and how it could happen again in a different form.
Just south of Lake Mary in the Mammoth Lakes area is the Mammoth Consolidated Mine, circa 1927-1933. If you are into touring abandoned facilities, this should be on your list.
See the photo gallery!
“The Mahan family was responsible for the Mammoth Consolidated, and donated the buildings and equipment that you see on the interpretive trail where remnants of buildings and machinery still stand.”
Samples indicated less than an ounce of silver and gold in a ton of ore or about $12.70 yield per ton in 1927.
After the Obsidian Dome rally, what to tour on the way home?

Mammoth Lakes is a resort area and a good home base to tour the Devil’s Postpile, Lake Mary, Bishop, and other spots on the southern end of US 395 eastern Sierra Nevada.
If you want to know what is growing along the Truckee River corridor and then north to the Black Rock Desert, Tipidan’s Burning Man Botanical Travelogue provides a good summary.
“Herein we present, for the enjoyment and edification of Burning Man enthusiasts everywhere who travel through Nevada en route to their spatial and temporal goal: a botanical travelogue! I am a botanist, and this cyber-nature-walk will include many plants that you’ve seen by the side of the road for years in this desert. It’s time you became better acquainted!”
“The tops of the ridges that flank the Truckee River are covered with growth of a very interesting tree, the Curl-leaf Mountain Mahogany. It too, is in the rose family” … ” extremely hard, wavy grained, and nearly impossible to cut with either axe or chainsaw”
“The City of Reno sits squarely within the Sagebrush Zone, but climate and human intervention have made Reno a much more interesting place. Reno has Japanese Red and Black Pines, numerous Ash, Big Tree Sequoia, Eastern Red Cedar, California Incense Cedar, true (Atlas) Cedar, Catalpa and my personal favorite, European Beech.” … “Reno is really a grand horticultural experiment in an early stage.”
Russian olive, tumbleweed, the Dutch Elm stories and many more … There is much to see and a bit of help like Tipidan offers provides a pointer to just what is out there.
Dave Seminara is in to tent camping. That just makes it harder to escape some of the obnoxious things other campers do. He lists 7 things not to do at a campground. It is a familiar list. Read. Remind yourself. Remember.
“One would think that campers would know not to snap the branches off of trees for firewood, drive fast around the campground, liter, and leave a fire unattended, but I’ve seen people do all of these things. Everyone slips up occasionally but a little common courtesy goes a long way, especially in the great outdoors.”
It’s sorta’ like picking a spot in the middle of a big dispersed area, getting set up, and then having someone else come along and decide to set up right next to you. Perhaps they think you chose a desolate spot because you need company or something? That something might include 24×7 electricity, music, dog poop avoidance games, and similar stuff as well.
It is one thing to be friendly and say “Hi” but entirely another to be oblivious to the needs and desires of others.
When it gets hot, where do you go? Someplace with shade, breezes, and a good connection to the power grid! That puts the Weed Heights RV park high on the list for a July Rally.
See the photo gallery of the SNU Rally at Weed Heights.
This place is just outside Yerington in Lyon County about 30 miles southeast of Carson City as the crow flies (32 miles bearing 111). It is near the company housing for the retired Anaconda Mine. With the price of copper these days, there are some interested in going through the 360 million tons of tailings again. The EPA has spend the last ten years trying to find cause to label it a supersite for waste. They’ve spent a lot of money haven’t been able to make the case (yet).
Next year, the plan is to be there when the A Night in the Country will liven up Yerington. The event is a benefit to the Boys & Girls Clubs of Mason Valley. There is dry camping at the Fairgrounds and it looks like that will be one big 24×7 party time there for the weekend.
The Weed Heights RV park is about 3 miles west and will serve as an overflow area or a camping spot for folks who want to spend the night sleeping or whatnot. You can tell the event managers have some experience as they ban booze, guns, and even pocket knives on premises along with video recorders and laser pointers. If you don’t like the rules, then look for Burning Man a bit later in the year … or maybe Hot August Nights, the Balloon Races, the Air Races, or some other event — lots going on in Northern Nevada.
It is a delimma. Most RVers tend to travel a bit slower than other traffic on the road. Sometimes speed limits are lower for RV’s, especially those with trailers or toads. Some RVer’s even brag about going slower than traffic, especially if that traffic is going faster than the speed limit. A commentary in the Washington Times takes a look at the dirty little secret about holiday traffic ticketing and notes a 1964 study of interest to slower traffic.
“David Solomon, a researcher with the U.S. Department of Commerce, spent several years collecting data on the risk factors that cause highway accidents. In a seminal paper published in 1964 — yes, almost 50 years ago — Solomon> found that the least risk of crash involvement occurred with vehicles moving near the average speed of traffic. He documented the safest speed to be about 5 mph faster than traffic flow. Conversely, Solomon’s data showed the odds of being involved in a highway accident rose dramatically as vehicle speed dropped below the average for surrounding traffic. The famous “Solomon Curve,” illustrated in the accompanying graph, has never been substantively refuted in the intervening years. The nature of driver behavior hasn’t changed over time.”
Wikipedia has an article on the Solomon Curve. A 2015 report on the Relation of Speed and Speed Limits to Crashes by Susan Ferguson describes it this way:
- Both studies found a U-shaped relationship between vehicle speed and crash incidence
- Crash rates were lowest for drivers traveling near the mean speed, and increased with deviations above and below the mean
- Low-speed drivers were more likely to be involved in crashes than relatively high speed drivers
This is why you can also be ticketed in many areas if you have several vehicles behind you trying to get by. It is also why you should try to keep up with traffic and pay special attention to getting out of the way when slowing down to turn or for any other reason, such as braking to avoid a ticket when seeing a cop at a speed trap.
There is also a ‘social’ problem when it comes to speed that is illustrated by the Ferguson report. It is a ‘science literacy’ problem that tends to confuse correlation with causation and the over-simplification of complex phenomena. It is embodied in the ‘speed kills’ mantra. Yes, higher speed means higher energy in collisions – just like the higher weight in RV’s will do – and that can increase the severity of a crash. That doesn’t mean that a crash is more likely, though. A look at the Nevada Crash Book, for example, cites ‘exceeding the speed limit’ as way down the list of contributing factors to vehicle crashes.
RVers tend to be mature drivers with good judgment. That means they are usually safe drivers. They can be better drivers if they are alert to the traffic flow and avoid interference in that flow as much as possible. The RV driver needs to stay alert and on task to be aware of traffic ahead as well as behind.
Drive safe this summer!
