Review: BioLite thermoelectric stove

I finally laid hands on one of these, the BioLite thermoelectric power generation stove and have had some fun trying it out. I've covered these before, in a WishLust post, so I was really happy when a good deal came my way.

The general principle is this: a steel pot, an inner layer with air-holes, a protective outer mesh to prevent accidental contact with the hot pot, built in folding legs, and an attachable, thermocouple driven, high-capacity battery, with both USB output and an internal fan to drive the fire.

The fire output is measured as 3.4 kW (at low power with the fan) and 5.5 kW (With the fan at high power). I haven't yet timed it, but BioLite state that it takes as little as 4.5 minutes to boil 1 liter of water, but obviously boiling times vary by strength of fire, which then comes back to the quality of the fuel used.

Officially, 46g (1.6 oz) of wood to boil 1 liter of water, when I used it, I simply chopped up a fistful of wood, and fed it in, feeding as it went. One thing to note is that with a small combustion pot, you need to feed it regularly, as it burns down rapidly, more so if the fan is set to high.

The varnished pine ex-furniture I was using here went up like a candle, but I expect that denser, or damper wood to burn a bit lower and slower. Charcoal would be an ideal fuel, but anything form hay (which I used to light it) to paper and cardboard, twigs, pinecones, whatever, would do. If you have the fire going, and can fit the solid fuel into the firepot, it will probably work.


The output of the USB varied, with the intensity of the fire, but is documented as 2W @5V at a continuous burn, and a peak output of 4W @5V. This in turn gives a phone such as the iPhone 4S (2G) 20 minutes of charging provides 60 minutes of talk time.

As with the boil times, charging times would vary by device and by the strength of the fire.

I really like how by clever design the fan/charging pod, fits neatly into the fire pot, with the thermocouple poking out.

When packed, its 21cm (8.25") tall, and 13cm (5") around, and weighs only 930g (33 oz).

The triangular trivet which clips over the scalloped triangular metal lip provides extra security for placing pots or cups on the top, for cooking, water sterilizing, or what-have-you, doesn't clip nicely back onto the lip when the charging pod is stored, but the whole package comes with a nylon drawstring bag, so you're covered.

The USB port is nicely fitted, and covered by a silicone flap which keeps it drip, splatter and ash-free when not in use. The external honeycomb grill shields you from direct burns, but still heats up pretty swiftly, so don't try picking it up once burning.

I look forwards to coupling this with my newly-replaced PowerPot XL and doubling the off-grid charging and powering that I can offer my camp-site.

If the little BioLite looks a bit small for your needs, they also make these jumbo versions too, the BaseCamp.

Review: Propper 19/67 notebook

 I've been a big fan of digital documentation for quite some time. I was an early adopter of PDA's, with Palm Pilot V and Mitac Mio-168 before settling on iPhones ... Before then I was a firm user of Filofax binders.

Sometimes there is just no substitute for dead-tree edition. Propper were kind enough to send me a set of pocket-sized notebooks in my recent delivery, and I've had one sitting along side my iPhone in my Hazard4 Escape RG harness and beside my passports.

There are times where you just need to be able jot some thoughts down in a way that you can share, or destroy, easily. Take these notes and map: I've got a map, shopping list, a to-do and task management right there. 

I could tear this page out, and take it with me, pass it to a friend, eat, burn or whatever.

The 48 pages are grid printed, and whilst the grids aren't either in fractional cm or inch increments, they are nicely uniform and pleasant to write on. They aren't waterproofed like the pages of a Rite in the Rain notepad, and could even be used as kindling, in a pinch.

Notepads, still not a dead technology, and better yet, they never run our of battery or need software upgrades.

Events: Trinity Day

"Trinity Test Fireball 16ms" by Berlyn Brixner

From Wikipedia

Trinity was the code name of the first detonation of a nuclear weapon, conducted by the United States Army on July 16, 1945, as part of the Manhattan Project. The White Sands Proving Ground, where the test was conducted, was in the Jornada del Muerto desert about 35 miles (56 km) southeast of Socorro, New Mexico, on the Alamogordo Bombing and Gunnery Range.


This test, which was found to have a yield of 20 kilotons

"Trinity-ground-zero-men-in-crater". 

ushered the world into the era of atomic weapons. Just 4 weeks later on August 6 1945 the first atomic weapon, Little Boy was used on Hiroshima .

 The people who developed the bomb, and tested it, people like Oppenheimer , Fermi and Feynmen took bets on what the outcome of the test would be, in terms of the expected yield, with bets ranging from 0 to 45kt.

Fermi took it a step further and offered to take bets among the scientists and military present as to if the atmosphere would ignite, and if so whether it would destroy just the state, or incinerate the entire planet.

Oppenheimer was reminded of the Bhagavad Gita; quote 'Now I am become Death, the destroyer of worlds.'. George Kistiakowsky is reported to have said "Oppie, you owe me ten dollars" .

For the first time, humanity was wielding the power of the stars, and producing weapons that were capable of effecting mass destruction on a strategic, geological and generational scale.

The Trinity tests marked the beginning of the era of nuclear warfare, which thankfully we've only ever ventured into in fiction and strategic documentation. And Preppers ....

Review: Propper - U.C. (User Configurable) pack

As first seen on BreachBangClear, where they make fun o' me accent, mate!

Inspired by the Marine Corps Assault Back, the Propper U.C. (User Configurable) Pack keeps you prepared, which is just the kind o lineage I like to have in a bag. I have a load of respect for the Gyrenes, my cousin had several long stays somewhere rocky and unpleasant serving in OEF, and if the design is tough enough for those lads, I couldn't ask for more. It’s designed to be customizable inside and out, allowing you to add the additional pouches and accessories you need when you’re on the move, depending on your requirements.

Made from 1000D Cordura nylonand wrapped pretty extensively in MOLLE webbing to accept whatever additional pouches you might require, the simple straight lines of this pack make it well suited to a variety of loadouts. No tight curved corners to try to jam kit into.


The pack measures 50cm (20") x 35cm (13") x 16cm ( 6.5", so you've got a lot of capacity to play with.

Hook-and-loop pass through openings on either side of the carry handle on the top of the pack offer hydration tube or cable pass-through porting, they are X-cut to keep dirt and other crud from making its way into your delicates.

The pack is wrapped in seven rows of six-channel MOLLE on the front, six rows of four channels on both sides and even two rows of nine channels on the bottom of the pack. That's a lot of coverage, especially if you have a variety of pouches you can load it up with.

Internally, all four sides are lined with soft-touch loop, to accept any hook-field accessories, be they holsters, tear-away medical pouches or any number of hook-field backed kit you might have ready to go. Propper were kind enough to send me a few different items to test out, and they seemed to really work well.

Both the inside back and front panel also featured deep zippered pockets running the whole length of the pack to give you a little additional storage, which is good because the inside is otherwise devoid of built-in compartmentalization. You NEED hook-backed accessories to have any fixed storage in this pack, internally.

Here's the inside of the front panel, showing off both the loop-field real-estate, but also the zippered pocket.

The back panel of the pack was fitted out with a stiff plastic board, to give the pack some structure when standing up. It didn't get in the way at all, but if you were really keen on shedding weight, you might pull it, if rigidity wasn't essential for you.

Similarly, the front panel featured a thin closed cell foam panel, to add some padding to the front of the pack. I didn't feel it ate a lot of real-estate, it added a little body to the flap, but if you wanted to shed weight and bulk, its removable.

 

On one side of the pack on the outside, above the MOLLE, a small, hook-and-loop fixed pocket, big enough for a phone, GPS or other small item is fitted. It wasn't super secure, being quite shallow, but certainly good enough for dummy-corded gear you need to access easily and often.

The top of the pack, just below the carry handle also has a small pocket, big enough for folded maps, small items like a compass or a flashlight, and other small kit you might want to have access to, outside of the pack. It's a slightly awkward size for other things, but snacks, maps and meds might well suit it.

One thing I found that the external zipper-pulls, which have these rubber grip-toggles fitted (which are good) come tied in a double overhand knot (which is bad). I pulled the knot right through the grip-tobble on one of them opening the pack, and immediately set-to retying them all with double figure-eight's. The pulls are easy to grip, and quiet, but the cord used isn't great, and I may well replace them with paracord entirely.

One of the things I really liked about the pack is that there are a pair of cinch straps on the bottom for securing gear. I often find myself with extra gear, or loot, to lug back home, and having a set of cinch straps built in can make all the difference. These, like all the main straps, have hook-and-loop strap-savers attached, to secure the excess webbing away when not needed. No more messy tape wrapping.

Inside the bottom of the pack is an isolated storage pocket, fitted with mesh-lined eyelets, top and bottom, which gives you a place to secure away wet, mucky or otherwise unpalatable gear and items away from your main pack. Perfect for a sodden poncho, or even a mess-kit. This is both zippered and also covered by the cinch straps that wrap from the back of the pack to Fastex buckles on the front.

Padded adjustable shoulder straps, broad, slightly curved and simple, secure the pack to the user,  and feature an adjustable sternum strap on sliders on the sewn-in webbing. Three additional cross-bands of webbing on either side give you mounting and cable or hydration tune feed points. Fastex buckles on the straps give you quick release options, and a wider webbing belly-strap is included for secure carriage of the pack.

One thing I really liked was that there are twin padding channels on the back of the pack, giving room for your spine to site between them, and offering some air passage to the fit for those long hot rangings.

One last feature, which I'm happy to see on this pack, and many others these days, is the triangular strap attachment flap, that gives the webbing and Codura of the pack a good purchase, taking the angular strain off the seams. Packs lacking this seem to always come apart here under heavy loads, so it's good to see Propper have taken this little bit of extra thought into their pack design.

This is a very utilitarian pack. Boxy but solid. You need to be aware that the internals are dependent on that hook-field backing to add any additional functionality, but other than that, this would fit in well with almost anyone's light to medium pack needs.

Events: 500 posts!

I am very pleased to report that I've clocked over the 500 post milestone, which is a whole lot of knives, pouches, lights and rants opinions about safety, security and the end of the world!

[edit] over the weekend I also cleared the 600,000 hits milestone too, rather cuffed, all together.

I've been a bit slack with the content in the last few months, combinations of new new work situations, rolling seasonal illnesses at home and just so much LIFE going on has sometimes made it hard for me to spend time in front of a keyboard putting thoughts to pixels for you all, but I'll keep at it.

I've been really pleased with the reach I've been getting, and the responses I've gotten from both readers and makers. It's always a big thrill for me to hear that my review prompted someone to get some good kit themselves, or to have a manufacturer want to have me review a product.

I'd also like to thank the Breach Bang & Clear team for putting me on as part of JTF Mad Duo, it's been amazing to be a staff-writer. Now if only it could be my 9-5!

One new development I'd like to make you all aware of is that I'll be opening up an online store shortly, and you will be able to purchase some of the cool kit I've managed to secure access to.

Thanks for following along, and as always, if love to hear any requests, suggestions and recommendations.

Be prepared, be safe, be Apocalypse Equipped!

Review: Hardcore Hardware Australia - TWI-02

I signed up for, and was one of four winners in a Hardcore Hardware Australia Facebook competition to take home their new and improved Tactical Writing Implement, the TWI-02. His has been a nice addition to my tactical pen collection. Currently I have the Cybernetic Research labs Tactical pen in my Hazard4 harness, and the Ti2 magnetic pen as part of my daily pocket collection the HHA TWI-02 is a very substantial competitor to what goes in my EDC.

The shaft of the pen is constructed from 6000 series, non-reflective, black anodized aluminium for extreme longevity and wearability, and features a recessed crown for positive thumb control with integrated steel pocket clip. The crown recession is via a series of stepped rings, which gives a very nicely textured grip, without leaving sharp edges to catch on anything. It is 147mm (5.78") long and 14mm (0.55") at its widest, and weighs in at
51g (1.8oz).

At the opposing end of the capped pen, they have incorporated a 46-48 HRC steel ‘ball’ tip for emergency glass breaking and impact applications. 

I've pounded a few things with this, and so far it's held up very well to my tentative testing, with no damage to either the ball, or the housing on the body of the pen. The cap screws down onto the body of the pen at the writing end, giving a very secure connection for when you want to deal out some percussive or pressure point based persuasion, but HHA avoid putting machined threads on the "outside" of the pen, by having a "clip-on" connection when you use the writing end.

There is an O-ring at the writing end to give a full seal making it completely waterproof when the cap is screwed down.

Knurling at key points along the pen aids a positive grip, as does the differing profile through the piece. Coupled with the recessed crown, you can get some really good gripping angles from this, whether you are writing or using the glass-breaker.

A steel clip fixed onto the side around the crown end of the pen is well sculpted and gives a really positive grip to a pocket notepad or wherever you stash your pen.

When it comes time to replace the refill the TWI-02, it will accept standard Parker and Fisher Space Pen refills, but for the life of me I haven't yet worked out how to do this. I think it must be the very tight tolerances that it is put together with, and I'll have to get in touch with the HHA guys when I run out of ink. 

Putting the TWI-02 up against a couple of my other "tactical" pens, the Cybernetic Research Labs pen
and the Ti2 Techliner pen the TWI-02 certainly comes up on top when it comes to imposing presence and size.

I had one attentive reader noted in my Sneak Peak post that the TWI-02 looks considerably like one of the Boker tactical pens and whilst they are very similar I don't think the resemblance is anything other than coincidental, the Tactical Pen world isn't very big.

I really like the feel of it as a pen, and also as an impact tool.

Review: Propper - Packable Full Zip Windshirt

Just in time for the Antarctic Vortex, first published in BreachBangClear: 

[EDIT] Now on the front page of Propper's website as "in the news"!
 
In my recent bundle from Propper, there was a lightweight shirt that caught my eye, and I've had some time to give it a good trial and can report back on it. Winter has rolled around here in Melbourne, and we get a fair share of wet and windy days. It rarely drops below freezing, due to the local geography, but we do get some cold weather from the Southern Ocean which can roll in unpredictably. Melbourne has a reputation for having Four Seasons in One Day, Crowded House even wrote a song about it. I hate umbrellas. Really, with a passion. Being as tall as I am, I'm forever being jabbed in the eye by them when the scurrying masses are running for shelter. 

So when I'm not restraining myself from throat-punching the perpetrators, I prefer to feel superior by wearing and carrying wet-weather gear for the occasional flurry.

Propper have catered to this nicely with their Packable Windshirt, which offers offers lightweight wind protection whenever you need it. This lightweight garment has to look of a jacket, but feels like a light shirt, due in no small part to the silky 100% polyester it is constructed from. With a Durable Water Repellant (DWR) surface finish, partially due to a surface coating, and partially due to the material and weave of e surface layer, I found that light to medium sprinkles were shrugged right off. Better yet, that weave stopped medium to strong gusts of wind dead. I was pretty impressed with that, given how lightweight it was.

Usually with this kind of wind stopping you either end up with a plastic-bag feel, or a Siege of Stalingrad feeling heavy coat. Amazingly, this had neither, I was hen suspicious that it would be a steam-trap, but somehow they've found that magic balance of permeability and breathability. This is helped along with the honeycomb-mesh pattern inner liner. This liner runs throughout the windshirt, and adds no appreciable bulk. 

Twin hand pockets with reverse sewn zippers grace the sides, with rubber-covers toggles and are silent operating, and a single pectoral pocket big enough for a phone, note book or in a pinch a STANAG magazine, but the heavier the load, the more it sags. A pretty spacious hood is stored in the neck seam, and is elasticised in a couple of spots to ensure a snug fit. I mostly kept the hood stored, and found that bulk added a nice snug seal around my neck, trapping heat in and keeping dribbles out. 

The sleeves have elasticised cuffs, to shut out the elements, which aren't my preference, but certainly work well enough. With arms as long as mine, I found that the Medium wasn't quite long enough, although the body-fit was good, so it meant that to feel comfortable I had to push the sleeves up. That or have half my wrists dangling free, and the shoulders dragging. For longer wearers, opt for a bigger fit.
The main front zipper is likewise a reverse zipper design, with the same rubber toggled zipper-pull, and has a overlap panel running its length to eliminate any wind chill through that seam. That's something that makes a lot of difference to me, and is also carries over into the design of the bottom seam of the windshirt, which is generously long, especially useful for us long-bodied types, and much like a cyclists shirt, ensures good coverage when you're crouched over. No more chilled kidneys! The main zipper is also double-headed, so you can upon the windshirt from top or bottom, meaning you can access belt-worn gear without exposing your chest to the elements, or from the top down.

One nice feature is that the windshirt comes up with its own storage pouch, accessible via a quite unobtrusive zippered pocket in the small of the back on the outside, you could also use this as an extra storage compartment for paperwork or what have you, as lon as you don't mind it being out of line of sight. The whole windshirt folds in on itself easily enough into that pocket, although I think I would have preferred it to have done so from the inside out, rather than outside in. Once packed up, it is a fairly small, and springy bundle, which I've used as an impromptu pillow and gear-rest and the whole thing fits into a cargo pocket easily enough, or jammed into the bottom of a pack. 

The cut and look of the windshirt is pretty neutral, no loop fields on shoulders or chest, no pen holders, or any external features other than the single pectoral pocket and two hand pockets, is is a pretty innocuous looking garment, perfect for being they grey-man in the crowd, albeit in black, coyote or olive.
