Four Letters Re: Brumby Compressed Air-Powered Well Pumps

James, Your comments about the relative efficiency of compressing air with a windmill are spot on. Most of the energy would be lost. In the real world, air compressors are only about 10 to 15% efficient at best. This is because air heats when it’s compressed. In fact, since more energy is converted to heat than to mechanical energy, a compressor is actually better at heating and cooling a house as a heat pump than it is at compressing air. So unless you could figure out how to drive the Brumby well pump and utilize all the waste heat at …


Letter Re: Brumby Compressed Air-Powered Well Pumps

Dear Captain Rawles, Are you perchance familiar with Brumby Well Pumps? They work using compressed air and are being manufactured in Australia. From what I can tell, this is a good idea if you can get compressed air to the pump. This leads to the next question: Is there a practical way of operating an air compressor with either a wind turbine or a mechanical means not requiring the grid or a gasoline engine of some sort? When I lived in Germany I saw a number of old Volkswagen air-cooled engines that had been converted to serve as air compressors. …


Letter Re: Last Minute G.O.O.D. Versus Well-Considered Early Relocation

James – We think along similar lines, as my wife and I relocated to Central Idaho in 1995, raising and homeschooling our four children here. We’re electrically functioning off the grid, engage in animal husbandry, grow what vegetables we can, and stock up on essentials we cannot produce and always meticulously rotate the stock. And we hunt, big time. I read the entry on your site today about the fellow who intends to travel ore than a thousand miles in a blink of an eye, and use this blur to make a life-changing decision based on distorted glances at sixty …


Seven Letters Re: Advice on Deep Water Wells in a Grid-Down Era

Hi James, There is a mission-oriented web site with a tutorial on making valve leathers at this site. There is other useful water well-related information on the site, too. Where John C. is living, if the static level is 400 ft., then he will be looking at needing a fairly deep well. If he gets by with less than drilling a 500 foot well I’d be surprised. Water wells here locally have a 350-400 foot static level and run 700-800 feet deep. The depth, quantity, and quality of water you find all depends on the area you live in, the …


Letter Re: Advice on Deep Water Wells in a Grid-Down Era

James, I know that I have seen posts about deep water wells, but when I search I really don’t see that many applicable posts. I am looking at a property where water [static level] is about 400 feet down. In a “grid-up” scenario, this isn’t really a problem, but I am looking for “grid-down” options for using a well at this depth. Not knowing much about the specifics of wells, I am not having much luck searching with Google, either. Would you be able to cover some deep well basics and some options for grid down/solar/backup pumping, specifically for deep …


Letter Re: Diverters and Pre-Filters for Roof Rainwater Catchment

Mr. Rawles, Regarding the filter design suggested by “Dim Tim”: Consider replacing the modified stockpot with a sink. A deep stainless utility sink would be ideal, would require little alteration, and could be set up outdoors at the downspout to drain directly to a retention barrel or bladder. In a SHTF scenario, an existing indoor sink could be modified by removing the trap underneath the sink. Collected water can then be poured into the sink, filter through, and drain underneath (a food grade plastic five gallon bucket fits quite nicely.) Regards, – Tamara S.


Diverters and Pre-Filters for Roof Rainwater Catchment, by Dim Tim

I have had this idea floating around in the back of my mind for some time now, and with all the posts on the subject here lately, I decided it was time to share it with everyone. I hope some of you find it useful. What got me started to thinking about this was a movie on DVD that I watched recently, titled Twenty Years After. (2008) It is about people that have survived a nuke war, the disease and death that follow, and the hope that humanity will still survive. It is not the best post-SHTF movie that you …


Letter Re: A Practical Tip on Using Roof Catchment Rainwater

Mr. Rawles- I sincerely appreciate your site and all of your efforts. In researching rain water collection recently, I came across a manual on rain water harvesting published by the Texas Water Development Board. While some of the data is Texas-specific, I found the overall information and descriptions of various harvesting systems to be extremely helpful. I suspect some of your readers may as well. In addition, I have received notice from the good folks at Safecastle that their next Mountain House [long term storage food] sale will take place between May 23 and June 5 and will include a …


Two Letters Re: A Practical Tip on Using Roof Catchment Rainwater

JWR: In response to today’s post, I would like to offer an alternate method to avoid going outside in the rain to flip the value after five minutes. Cut the down drain pipe into about 5 feet from the discharge elbow. At the elbow end install a blank over the opening. Drill a small hole in the blank, perhaps 1/8th inch diameter, and reattached the outlet ducting to a container to catch the runoff. At the above cut in the drain pipe, install a “T” and an ell to move the water downward into a barrel. [During each fresh rain …


Letter Re: A Practical Tip on Using Roof Catchment Rainwater

Jim There are simple old time solutions to the possible problem of collecting and using “polluted” roof gathered rain water. Add a splitter, (an upside down Y shaped piece of pipe), to the downspout before the pipe runs into your cistern or rain barrel. One side of the “Y” goes to your catchment, the other to the ground or drain. Add a simple flip value to the inside of the splitter. During the first 5 minutes of any rain, turn or flip the valve to run the water out onto the ground or into the usual drain. Once the roof …


Letter Re: Concerns About Toxicity in Water From Roof Catchment Rainwater

Mr. Rawles, I searched the forums to no avail on this topic. In the Pacific Northwest, a common roof setup is untreated wood shakes with copper ridge caps and flashing. The rain hits the copper which leaches chemicals onto the wood shakes to inhibit moss growth. On other sites I’m reading conflicting thoughts on whether this amount of copper renders the water unsuitable for rain catchment into a water barrel for vegetable garden irrigation or a cistern for human consumption. Some folks seem to think there is more danger from the concentrated nitrogen in the water (bird droppings, raccoon feces) …


Letter Re: Learning the Details of Self-Sufficiency

Jim, I’d like to add an additional perspective on the letter on “Learning the Details of Self-Sufficiency” — the conscious competence learning model. I’d like to pull back the shade a bit on why ‘just buying stuff’ and reading books isn’t going to cut it when the balloon goes up. Many folks are ‘buying things’, reading books, searching the internet with the thought that when the time comes, they will begin living the self-sufficient lifestyle in the country. The aforementioned letter points out the folly of this approach. I just want to take a step back and look at why …


Two Letters Re: Advice on Treating Pond Water

Hi Jim, I just got the “Rawles Gets You Ready” preparedness course the other day and love it. I also just finished the audio CD [that came with the course binder] and that was a great addition to the book. My husband has said ‘you can just boil water’ to make it available for drinking water, and I don’t think this is so. [In the course binder] you only speak of having water filters of various kinds. Can you tell me if water is retrieved from a pond how to treat it? Also, can you go into detail as far …


Letter Re: Some Preparedness Lessons Learned

James, The need for usable skills in tough times, goes without need for embellishment. The grand question is: which skills are the most valuable? In any situation the basic needs are obvious – food, shelter, and clothing. Choosing what I would concentrate on learning, became predicated on what I could do, and what the community could provide in stressful times. I moved some time ago from the gulf coast to Tennessee to retire and begin preparing for the coming events. I moved into a community which is pretty much self sufficient, mostly by religious choice. Livestock husbandry ranges from cattle …


Letter Re: A Source for Potable Water Storage Tanks

Jim, I enjoy your blog. Recently a few friends and I started to look for potable water storage tanks for long term storage. Most tanks either were not designed for long term storage or the retailer does not have enough information. (Ever since the bottled water cancer scare, the composition of the plastic has taken on a new importance.) Wanted to pass on to you a link to WaterTanks.com, a company that has really been great leading us through the process and willing to sell us 1 or 100 tanks. Our sales rep is James Opferman. We are going to …
