This all is working in basically the same way as a normal air conditioner:
1) compression of some refrigerant (driving the compressor is where the high electrical load comes from)
2) Allowing the heat created to dissipate (cooling fins on the back of your frig or on the exterior side of your A/C unit)
3) expansion of refrigerant (the temperature drops in that section of the A/C's plumbing and a fan is blown over it)
4) re-compression of the refrigerant.

As with blowing cool air out from your mouth, steps 1 and 2 are inside your mouth and step 3 is outside your mouth.

The heat generated will be at the neck of the bottles, outside. Problem is, you'll need a fair amount of wind to create the pressure to drive ambient air through the bottles necks. Also, dropping the air a few degrees on a hot day doesn't do much, at least not for me.

I can think of a lot more practical ways to get electricĂ­ty free cooling, e.g., upwind-facing air intake leading into earth tubes with the exhaust blowing their cool air over an air intake radiator. You don't want earth tubes venting directly into a living quarters, though. Too much of a risk of mold spores you can't control in the underground part of the earth tubes.

Or...here's a thought. Build a wofati.

Glad to see the hand-powered washing machine being put to good use by being stashed inside one of the stalls in the skiddable shower. Seems like the perfect place for it.
I live in central Florida and am building an off-grid tiny house. Designing a water system has been my main challenge (and main obstacle to moving to the location I intend). Reading this thread has been very informative.

On one hand, I'm contemplating paying to have a well professionally dug, and let that be the end of it, but I would prefer to have a self-built system drawing lake water and using a slow sand pre-filter leading to ceramic filter (such as the Monolithic ones mentioned above).

I'm trying the find the sources to answer these questions.

1. Is my lake, spring-fed (from below, as is almost all of Florida's lakes) and a near perfect circle 660 ft across, large enough to be a good source?
2. If so, where exactly in the lake should I draw from? The center surface? The center below the surface (and how far below)?
3. Where can I find plans to build a slow sand filter suitable to my low-level needs (only one person's worth of water)?

Thanks for any input on this.

If you live in an area where the soil is 100% sand (as I do in central Florida), do you accept that as your base or do you buy topsoil from a gardening vendor and have them dump a truckload on a tarp for you to distribute as you build the mound?

Maybe it's a Florida thing. This hive was under a friend's deck near Leesburg, Florida for seven years. When his wife said enough was enough and it had to go, I harvested it into a Warré hive and had it in my apiary for just over a year. Normally robust, it faded away just this last summer (I never harvested any honey from it in the 14 months I had it). I'm wondering if being high over a cement floor had protected it for its seven years of existence from Small Hive Beetles (whose larvae develop in sandy soil beneath the hive) but my putting it into a standard apiary setting of only 18" off the ground sealed its doom. Hard to tell.

As for the original question, I'd think it was either a swarm who, like the one that started this hive, decided being outside was good enough (the tree must have provided enough rain protection) or, as mentioned elsewhere, it was a swarm that just couldn't wait any longer to find a home.

A couple of thoughts come to me reading this.

One, in life we're usually faced with a choice; be the person who everyone likes, or be the person who gets stuff done. Very rarely can we ever be both.

Two, in almost all situations, we are either the giver (host, etc.) or the receiver (student, guest, etc.). It's always seemed very clear to me that if I am the giver, be it a ride in my car, an experience I'm offering, or anything else, my needs are to be accommodated. If I'm the receiver, I need to pay close attention to what the giver needs.

Like you, I'm baffled when that's apparently not obvious. Unlike you, I usually don't stand up for myself and just let my opinion of the transgressor diminish. My ambitions are small, however, so I can get away with this. Your ambitions, Paul, are large, so I think you should waste no energy on those who don't get it. Lead (you are), follow (they should), or deal with the justified wrath of an overall-wearing giant. The ability to deal with that kind of frankness, like the ability to wear a name tag, should be the price of admission. If you don't get it, then you don't get to get it.

Done! It should arrive Oct 6-8. Mind you, this is all about me because I want to use your jumps one day. Paul can tell you where my plot of land is (I'm a deep rooter).

Why not just send it with the pee?



The pee is sterile and good nitrogen fertilizer straight from your body. Butt wiping water, on the other hand, needs to be decomposed for a full year to be safe to simply apply to one's land (as pee is right away).

I first came across this concept when in Nepal in 2004 and confronted with a toilet with nothing more than a bucket of water nearby with a cup in it. "What on earth am I supposed to wipe my butt with?" I pondered for five minutes before coming to the inevitable conclusion. As a westerner experiencing this for the very first time at the age of 49, this was an absurd option. Since then, however, I do it all the time and feel much healthier.

An aside: this finally gave me a clue as to what the big deal was over the supposedly unclean left hand found in many middle-eastern cultures.

As I'm building a tiny house, I've given much thought to my ultimate toilet system. I think I've come down to a pee-diverting, sawdust composting system with a secondary diverter for cleaning myself as described above. This will be the only blackwater produced, and in a much smaller volume for which I hope to devise some evaporation tank that can reduce this to solid waste for the compost container (a large garbage bin) as well.
