The versatile Duffy Shelter can be used as an emergency housing unit, first-aid support and cozy trailer for glamping.
as usual, it is not design ideas that are missing in this kind of project, it is money to buy them in larger quantities when the need occurs. I saw many iterations of the same idea over the years, but none were relevant in terms of cost in disaster-relief situation.
But for weekend warrior, it looks legit because of its simplistic approach. No useless features!
Concrètement, vous pourrez mettre à brûler du bois un peu humide dans l’IKEA Stove : il continuera à chauffer et fera s’évaporer l’eau du combustible. Cette rusticité d’usage est la caractéristique principale de l’IKEA Stove : Mode d’emploi con comme la mort, pas de petites pièces que l’on peut perdre ou casser et ça marche dans 99% des conditions. Point barre.
Tacticraft présente le hack spécial bushcraft: le Ikea Stove, un réchaud à bois mono paroi.
- fabrication facile
- 110gr + ajout de 5 piquets de tente = 190gr
- accomode des popotes jusqu'à 1L. (une Snowpeak 900 peut s'insérer à l'intérieur au millimètre prés)
- nécessite un approvisionnement constant (toutes les 5min environ) en petit bois mais la grande inertie thermique le protèges des variations liées au vent, pluie, etc...
A spark gap transmitter is fairly simple. Send a high voltage current through an air gap, when the resistance of the air breaks down a spark will cross the gap. When this happens electromagnetic radiation is emitted
Homemade TIN CAN ROCKET STOVE. Simple DIY. no special tools required. easy clear directions. This stove is great! Items needed: 3 metal cans, gravel/sand and/or dirt! that's it. only tools i used were a hacksaw, pliers and a drill. powerful stove. wind and rain resistant. can cook full meals using very little fuel (leaves, twigs and small sticks).
Unlike a conventional battery that contains both cathode and anode material, oxygen from the atmosphere is one of the battery reactants and is not packaged within the battery. So a cell can contain more zinc fuel in the anode to provide more capacity, or run time, than a conventional battery. As a result, the MetAir® Ranger PPS has higher energy capacity-to-volume (and weight) ratio than any other commercially available battery.
interesting battery tech. 400$ MetAir Ranger Battery for 192hours. Not clear if you can buy "power cartridge" to change cells within the battery though.
More info from the FAQ:
MetAir® Cells Zinc-air primary batteries offer a long stable shelf life, generally up to three years (before initial use, sealed in the original airtight packaging). Once activated (exposed to air), the MetAir® battery should be completely utilized within three months.
if properly re-sealed to cut-off the air supply, you can slow the discharge rate and re-use the battery again for up to two months, depending on remaining energy capacity.
Zinc-air batteries are safe, eco-friendly, non-toxic, and nonflammable. MetAir cells contain zinc in the anode gel, a non-combustible, non-toxic material. The MetAir batteries contain NO added mercury, lead, lithium, or cadmium.
They are primary (non-rechargeable) cells which can be conveniently used and replaced. Once discharged (completely utilized), the MetAir® Power Cartridge is replaceable and can be disposed of in the normal waste stream
PVC pipe is inexpensive, readily available and easy to use. It also contains potential energy when bent, making it an excellent bow making material. You can mold it using nothing more than your hands and a heat source. On the off chance that you make a mistake forming it, it’s really not a problem. All you have to do is reheat it and form it again. Once cooled, it will hold the new shape, while maintaining its combination of flexibility and rigidity.
Fontus is a self-filling water bottle for your bicycle. This device collects the moisture contained in the air, condenses it and stores it as safe drinking water. Powered by solar cells, it can harvest up to 0,5 l water in an hour´s time under the right climatic conditions.
For solar charging, the company is offering its 50 W Predator solar panels, which weigh in at about 4 pounds and are said to be both waterproof and shatterproof, and which are designed to be able to be chained together (up to 5) to charge the Kodiak. Two of the panels should deliver a full charge to the Kodiak in about 11 hours, according to Inergy, and this time can be cut further by adding additional panels to the system
yet another example of affordable and compact solar solutions that can deliver decent power. However, lithium-ion batteries recycling should be addressed and optimised so we don't just switch from one fuel issue to another (from Middle East to South America) and don't rely solely on environmental regulations and goodwill to boost recycling effort.
Medicinal wild plants have been collected from the landscape and added to home gardens for centuries. In modern times, the cultivation and use of these healing plants may represent a healthier way of living to the homesteader crowd, and a sustainable re-supply plan for preppers and bug-out enthusiasts. While these home remedies should never take the place of professional medical care, it’s nice to have a sense that you are not helpless.
We often use a backpack, as our BOB, because we know that our car, truck, SUV, ATV, motorcycle, or scooter, may not run (EMP), or stop running (no fuel, mechanical breakdown, or collision).
A Bug Out Bicycle overcomes the EMP and fuel obstacles, and would be great if you're leaving from your house, but how many people can carry a bike, even a folding bike (plus spare parts, tires, tubes, chains, cables, and tools) in their car, everywhere they go?
If we REALLY want to prepare for the "worst case scenario" (plan Z), what we all need to prepare for, is walking.
A pretty good account at possibilities in terms of Bug Out Trailers
the bow part is very well put and it comes as no surprise that "making your own arrows is really more of a process of assembly than of construction". Making them from scratch is a very complicated process.
I wanted to test the ability to use Google Earth as a navigational tool while under sail. I brought the following tools:
Windows Laptop – some of the tools I used were only available for Windows.Google Earth – just the basic free versionGPS – used a Garmin 60Cx – a nicely featured GPS with color screen and charts. But, a basic Garmin GPS with a serial or USB port would have worked just as well.EarthNC – EarthNC offers very nicely converted digital vector nautical charts for Google Earth (KML format) from the US National Oceanic and Atmospheric Administration (NOAA) – over 600 charts. The EarthNC charts take very good advantage of advanced KML features to present colorful information for the charts (depth contours, buoys, hazrds, etc.) in an eye-pleasing and informative fashion in Google Earth. See my earlier review of EarthNC.GooPs – GooPs provides tools for linking your GPS with Google Earth and drives your view in GE so you can use it for navigation. Even the Pro version only costs US$14.95Franson’s GPSGate – I needed this in order to allow GooPs to think I had my GPS hooked up by serial port instead of the USB. I’m told GooPs will soon have its own ability to handle USB GPS interfaces. I used the 14-day trial version for GPSGate for my review. It worked perfectly.
the goal is here is to put together some shelf stable 800 calories meals for our BOBs. The requirements were that the meals had to be nutritiously balanced and significantly cheaper than MREs. And I wanted the foods to be as close to our ordinary diet as possible so we don’t suffer digestive shock.
