Capillary Filtration

This method of water filtration is very easy, gives good results, can be done by anyone but is time consuming. 

You also will have to SODIS the filtered water afterwards, but if you expose the water to UV light during the filtration process your water will be ready to drink in no time!

Cut a thin stripe of fabric and let one end hang into the dirty water and the other end in the receiving container. The receiving container must be a bit lower than the "dirty one": The fabric will soak up the water which then will drip into the receiving container: FILTERED...or rather: Containing less visible particles than before.

On the pictures I used a stripe cut out from the bottom hem of an old the T-shirt was still good to wear (at least it protected my skin from cold and UV)

After two hours...

The Shower Cap Solar Still

The complimentary shower cap you get in hotels is probably on the top-ten of least manly items in the universe.

However: It can come handy when/if your all inclusive vacation in some third-world country, turns from a belly full/brain empty bliss into a living SHTF nightmare.

With the shower cap and the generic bathroom waste bucket you can make a solar still in no time. With it you can turn sea water or brackish water into drinking water.

Fill a bucket with a non-drinkable liquid like sea water. The darker the bucket is the better.

Put a receptacle in the center of the bucket.

Make sure to grab a handful of those of the cleaning Cleaning Lady`s cart
when unattended (or just ask nicely...)

The shower caps lining makes it easy to create
an airtight seal.

Put a heavy object right above the receptable.

And let condensation work its magic.

After only one hour I already have 100 ml. 😁

Testing: EDC Container

I found this neat container on Gearbest.Com for 4$ a piece and thought I try it out. I was pleasantly surprised that shipping was for free...and when I received my package 42 days later I found out that free shipping also means "painfully slow shipping". Well, you get what you pay for.

Apart from that I must say I am well pleased!

The containers are made out of air craft grade aluminum.
Am positively surprised about the thickness of the material.

The containers are about 10 cm X 3 cm. A bit to large
to be a part of your key ring,

The thread gave off a soul shattering sound.when I opened/closed
the container . But a wee bit of silicone grease took care of that.

I will test if the container is waterproof.... dropping it into a bucket with water for 3 hours.

Aaaand it is totally waterproof. I don`t know if the silicone grease helped
or not. So yes, I am well pleased! Now I just have to fill it with some equipment.

The Cardboard Solar Cooker

The internet is full with instructions on how to build a Solar Cooker, the range goes from the extreme simple (The "Pizza Box" Solar Cooker) to something highly advanced that looks more like a Hadron Particle Collider than an usable Cooker.

I wanted the Cooker for cooking of course but also for SODIS when I don`t have my ceramic filter or the resources to boil water.

I eventually found a Company  ( CooKit ) who made foldable Soler Cookers out of laminated cardboard.

Awesome! That meant I could have one in my backpack!

Scrolling down the page I found that they offered you a plan on how to build one identical to their product.

If you have a printer you can print out a pile of PDF`s which, when you glue them together, gives a 1:1 template. 

Now you just have to put the template on a larger piece of cardboard (we duct-taped two pieces fine!) and cut along the dotted line.

I printed it all about and then asked Krzystof Lis from the blog if he would like to play with this project as well.

He had the brilliant idea to use a needle to mark the lines of the template on the cardboard so we could use the template over and over again.

Well enough said.

Here some pictures from the first cooking experiment with the homemade CooKit:

Here it is. According to instructions we should have used tinfoil
but used an emergency blanket instead simply because its in my EDC.

Finding a highly proffesional platform for my solar cooker :-)

I keep it simple and put a frozen pizza baguette in the oven. The plastic bag
around the baguette is a baking bag, you can get those in every supermarket.
The bag accumulates heated air around the baguette and shortens the cooking time.

The cheese starts to melt after 20 minutes.

Ready to eat after 50 minutes!
Conclusion: In our climate a Solar Cooker has its limitations, but I find it extremely valuable in terms of killing germs in my drinking water.

Freezer Bag vs. Condom

When you get into puberty you get hairs in weird places and you spend some years (depending how good your schools sex-ed programme was) being confused about sex, contraception etc etc etc.

Well, as far as I can see the confusion lasts: In Survival or "Tactical" forums Condoms are being discussed with the same enthusiasm as knifes (which tells you everything you need to know about the persons writing posts in these forums) in terms of survival/water storage. APPARENTLY because fighter pilots in 2 WW used them...just in case when being shot down over occupied France.

Joie de vivre!!

So,  because of that, a lot of people are carrying condoms in their EDC or survival gear to store/transport water in.

The questions and answers regarding Condoms in abovementioned forums are borderline funny:

"Is the lubricant poisonous when swallowed?"

(In the age of Cherry flavorred lube I guess that`s a "No!"

"Is the spermicidal the condom is coated in, bad for me when swallowed?"

(Well lad, that depends on how much you want to drink of it.....but have you thought of TURNING the condom of the left side? Now your water will have a pleasant cherry taste.)

Other questions regarding "the right size" and "type" are legion but do not deserve to be listed here.

Anyhow: Condoms are really great. Also in terms of transporting water. But for survival/EDC purposes I prefer the good old Freezer bag.

And here is why:

Transporting water in a condom?! What a waste of a perfectly good contraceptive!

When filled with water a condom "goes" practically EVERYWHERE: Its going to be a large, wobbly sausage with a skin only a fraction of a millimeter thick. That makes it a bit difficult to transport, especially if you do not have a bag to carry it in. Freezer bags have a "form" and really though skin which makes them pretty puncture resistant and easy to transport.

With a bit luck and the proper use of a slipknot you can use the condom to store water a "few times". A freezer bag can be used......"many times more" than a condom.

And last but definitely not least: Freezer bags are made out of food grade PE which makes them suitable for SODIS treatment of your water ( Here`s more about SODIS ) whereas latex (the material condoms are made out of) filters most of the UV radiation.

The IKEA Hobo Stove

I do not protest to much when being dragged to IKEA: I can get a large variety of scandinavian foods there...and most important, LICORICE!! 

That`s right: Its almost impossible to buy licorice in my Country-Of-Choice and it drives me insane.....

But back to the topic: I found this neat flat ware holder (don`t ask me what its called..It could be "KNYLLA", "BOENK" or "LAGERLOEFF".... I don`t get these names) for around 2 Euro.

My better half was impressed and mentioned something about that it would go well together with our new brushed steel sink.

Ehm, sure honey.

I thought it would make kick ass Hobo Stove and I was right!

A stainless steel cylinder with a lot of air vents.

Cool, this so called "flat ware holder" comes with a grill!

Lets get some fuel in that flat ware holder an see if it lives up to expecatitons.


I feed the Hobo Stove for nearly 2 hours to see if the material can hold.

And it does!

I think it is time...

...for breakfast!

My recipe for porridge:
2 parts water for every part of oat.

Aerial Photgraphy: Rømø / Denmark

My very first (successful) attempt at Aerial Photography with a kite (KAP) on the island of Rømø in 2015.

I used a little GoExtreme Nano and attached it to the kites line...using only a Constrictor Knot

My favorite and largest kite (3 m span) with the camera encircled in red.
Weather certainly is great for it!

And here how it looked from above:

The Hobo Stove

Hobo Stoves are popular for a reason: They are cheap, light weight and extremely fuel they can be improvised out of nearly anything. 
To put it simple: A hobo stove is a can with holes at the bottom allowing air to be drawn into the fire resulting in a lot of heat emerging on top. 

Super hot flame with a minimum of fuel.

Take a can, any can over 500 ml in volume will do.

My tool for the job: The Hacksaw Survival Knife

Cut min. 4 flaps on top and bottom and fold them inward.

Place fuel at the bottom and set on fire.

The reason for cutting holes at both end becomes evident when you
place a pot on top of it: Without these holes the fire dies.

The Danish Candle

The Danish Candle is very similar to the The Swedish Candle and the basic principle is the same.

The difference lies in the way of making a Danish Candle:
There are not so many chainsaws to go around in Denmark, so we boring flatlanders use what else is at hand: The Power Drill!

Take a log and the largest drill you have and...

...create a large hole in the side of the log by drilling a lot of smaller holes.

Using the same method: Create a smaller hole on top of the log...

... so the two holes connect.

Take all the sawdust you have from drilling and some smaller twigs.
Set on fire!

The draft creates a hot/large flame,

Keep feeding the fire with small twigs.

I could use some coffee, so I put the percolator over.

Three minutes later.

Use sand to put out the fire.

This is how the Danish Candle looks like after 45 minutes use.
