Paint can rocketstove: field test

Rocket stove made from a paint can and 3 smaller 300 gram food cans. Small rocks used to create gap between pot and stove

Rocket stove made from a paint can and 3 smaller 300 gram food cans. Small rocks used to create gap between pot and stove

This rocket stove was was constructed out of a 5 Liter ( 1.32 US  gallons ) paint can and 3  x 300gram  ( 10 ounce) food cans. The grey paint was not fully removed from the can and some is still visible. I would recommend that if a paint can was used the paint is completely removed with an appropriate solvent, turpentine or water depending on the type of paint base. If a solvent is not available the can can be heated in an open fire to burn out the remaining paint.

Boil time for 1 liter of water approximately 10 minutes.

dry wood ash was used as insulation.

Some small rocks were use to create the pot stand.

The paint can handle was left on to create an easy way to move the stove.

Addition of the fuel shelf helped the stove produce better air flow an prevents over filling with wood fuel, the shelf was held securely in place with a small rock.

Complaining does not help

Complaining will not make a bad situation better.

I went for a hike recently.
The brief for the journey was that we were to go about 3 km on mostly dirt roads to a creek.
The environment was dry Australian forest, mostly eucalyptus trees.
Thinking that the creek would be full of fresh water I foolishly didn’t take any water.
The journey was mostly down hill on the way there. The weather turned from warm to hot and humid.
The creek turned out to be a largely stagnant trickle. I had no way to purify the little water that was there.
Fortunately my companions had brought some water with them, but on the way back to camp we quickly ran out.
I was beginning to suffer the effects of dehydration and heat exhaustion. I felt very tired and even a few minutes walking was exhausting.
We stopped many times on the way back to the camp for me to recover some strength.
My friend asked me on the way back during one of our many stops ” What’s the most important thing for survival?”

Immediately I said “Knowledge”

Had I known the water in the creek was not drinkable I would have taken water.

Had I known the weather would become so hot and humid I would not have carried a jacket in my bag.

Once we had arrived back at camp we all drank lots of water and rested.

My friend commended me on not complaining about my obviously exhausting return journey.

I said ” Complaining never helps, so there’s not point in doing it”

He nodded knowingly.

Hearing the complaints of other people simply converts their problem into your problem.
It multiplies their irritation and makes that person your irritation.
One person complaining a lot can really destroy the morale of a group,
and then people will start arguing and fighting rather than attempting to solve the real problems they are being faced with.

So in the forest (or other places away from civilization) there will be hardships,
how you deal with them physically and emotionally is your choice.

Occasionally the person suffering will be you, it’s easy to ask people to not complain when you are not the person suffering.
When the suffering person is you, remember to not complain, you won’t be respected for your weaknesses, but you will be respected for being laconic.

Soil stove

If found this looking through old documents.

A stove made from a mix of sand, soil sand an dung slowly piled up in the corner of a house. I think anthill sand is coarse sand, soil being loamy soil, and dung having fibre binder like mud daub houses.

All natural products, no metal or money required. Get primative but use your head, this likely to  work only in hotter/ drier regions. Uses less fuel and produces less smoke.

3 week construction time.

A stove for free made from soil, sand and some cattle dung with straight stem branches for moulds.

PV (solar panel) and charge controller with battery

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.

The panel

80 W  (maximum power)

12V

P = VxI

P/V =I

80/12 = I

6.66 A =I (maximum current)

 

The charge controller

12V

6A

P= VxI

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.

War: It’s all about the oil and gas, and who controls (and profits from) it.

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.

Collapse (2009) Mike Rupert, Directed by Thom Powers

 

 

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.

Rocketstove: Making one from metal Olive oil container

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.
