Depending on where you are you might want electricity.
Solar power is a convenient, low maintenance way to get electricity if you have sunlight.
For this example I will consider a 80W 12 V solar panel and a charge controller capable of 6A at 12 Volts.
80 W (maximum power)
P = VxI
80/12 = I
6.66 A =I (maximum current)
The charge controller
P = 12 x 6
P = 72W
Close enough to matched, remember the panel lists it maximum power not typical power rating.
A charge controller is a fancy battery charger which can put unused solar power into stored energy into a battery.
Usually there is a load circuit for things you want to run directly off the solar panel and a battery charging circuit. For this example there is a maximum load of 72 watts from the controller load wires.
For a larger load than the controller allows disconnect the battery from the charge controller and use the charged battery.
There is often a wet type battery for flooded lead acid cells check you documentation as to whether it is connected to the positive(+) or negative (-) terminal of the flooded battery.
A typical arrangement:
PV charge controller and battery wiring diagram.
For 12 Volt setups the car cigarette plug and socket system of connectors is a good idea, simple and common. There is also a wide variety of electrical items made especially for this connector format.
The connectors on solar panels are waterproof, the connections on the charge controller are not, make sure they are waterproofed or kept away from water.
I was going to write a long article about this, but in my research I found someone else already had done so.
Kudos my friend.
As you can see Iran is very close to the center of a large struggle over whether oil goes east or west, and its sitting on the worlds largest reserves of natural gas and a substantial quantity of Oil as well.
Any discussion about Iran must be made in the context of Oil and gas because that is what any possible conflict with Iran will be about.
Mike Rupert explains peak oil and it’s connections to peak population and the general instability of and oil based world.
A personal, sometimes intimate interview, with some archive footage to help explain some concepts and parts of history.
Mike’s solution: grow your own food, disconnect from oil and get to know your neighbors.
For the last few months I have have comments turned off. There was a lot to say and I didn’t want distraction. But don’t think that meant I wasn’t listening to you. I pay attention to what people read and what search terms lead them here.
Rocket stoves have been a popular search item so its time to give you even more information.
I’m going to make one. I’m starting with a 13kg Olive oil can and I’ll have photos for all the relevant steps and a boil time test.
13 Kg olive oil can. 31 pounds in weight
The starting material a large Olive oil can. restaurants and other food businesses throw these away quite regularly, so that’s a good place to start looking if you don’t usually buy oil in this size container.
It’s convenient that there is a large round hole in the center of the top so I wont need to cut one there. Somewhere in the purple band is where I will cut a hole for the pipe which will be the elbow bend pipe.
There is a small handle on the front which i will probably keep as it will be useful for carrying the stove if I need to move it. i think the handle will be better at the front rather than the back as it will stop the ashes falling out for the bottom of the elbow.
The next step will be using sand paper to remove the paint from the can. If the paint is left on the can, it will burn and produce unpleasant and possibly toxic fumes.

Apart from the obvious intended use of pruning trees, the compact folding pruning saw allows you to collect small branches easily.
A saw is safer to use that a axe or heavy knife in cutting wood. One of the most common sources of dry wood in a forest is dead-fall.
Dead-fall is dead or broken branches fallen to the ground, and are often very dry and difficult to cut will axes as the will act like a spring when hit.
Sometimes dead-fall is a branch upside down and very dry, because of this it makes excellent fire wood or construction material.
The saw can elegantly cut of the exact pieces you want and even help you create items form the wood with precise cut lengths and flat ends of wood.
The saw is also very light compared to a small axe and very small, about the size of a small axe handle.
Folding pruning saw, compact and allows straight cuts in wood with little effort.
Price about $10 for average quality.
Available from hardware stores and gardening supply stores.

I try to avoid using idioms and proverbs in writing. But sometimes an idiom is so true it is worth explaining.
One picture is worth a thousand words: means a single picture can convey so much meaning it replaces the need for ( is worth ) a thousand words.
Sometimes a single image or diagram will give the right reader so much information.
I hope this picture is conveys a lot of meaning to you.
A society built on cheap fossil fuel, this is what that society becomes.

Your hands are very important so you must protect them from harm.
You may need to handle sharp or toxic materials so you should have some kind of protective gloves.
minimal protection form sharp objects, good protection from many toxic materials.
medium protection from sharp objects, low protection from toxic materials.
Leather ‘riggers’ gloves
good protection from sharp objects, medium protection from toxic materials.
When in an outdoors environment your hands a likely to get small cuts. While this may not sound significant small cuts can become infected easily and allow pathogens easy entry to the body. Small band aids may seem to be a solution but preventing the problem is better. band aids may not stick for very long and become in effective quickly.
Gloves a good idea.
Example scenarios for use:
removal of broken glass
moving a rotten log which nay have venomous insects under it.
handling a fish which has one or more spines.
gardening or handling potting mix.
Threads is very disturbing movie aired by the BBC in 1984, showing the lead up to and aftermath of a nuclear war.
The into is very apt, our strength and weakness is the threads that connect us.
The premise was the cold war going hot suddenly, but many nuclear weapons remain today and only a dozen or so could cause serious disruption and the very real likelihood the of societal collapse depicted.
Of course several other possible scenarios could produce the apocalyptic collapse described, but surely nuclear war is one of the worst, especially considering the widespread radiation enduring for decades or even centuries.
Extremely disturbing and quite depressing

It may seem like a mundane item but it’s extremely useful if you have a good pair of scissors.
Stainless steel is key here, durable, rust proof, sterilizable, retaining edge for extremely long periods of time.
For things as basic as cutting your fingernails and toenails to small craft projects these come in handy.
Of course because they can be sterilized in boiling water and/or bleach they can be useful for medical purposes ( medical knowledge not included).
A good medical kit will include scissors of some kind but its worthwhile having a pair of scissors for general use.
As pictured the scissors should have a small screw in the pivot point this is so they can be tightened if they become loose.
I have had these scissors for almost 20 years, a testament to how durable stainless steel really is.
