A place for me to review the various rugged, nifty and needful kit that I've accumulated, for every-day preparedness in the event of accident, disaster or world-shifting end-times Apocalypse, be it zombies, triffids or Mayan divide-by-zero errors.
We had a scheduled power outage at our place over the weekend, which we had completely ignored, and it took us a little by surprise, but thankfully, we have gas-for cooking and hot-water.
What we didn't anticipate is the power-hungry nature of the ladies Pokémon GO running iPhone 5's. We might have lost wireless internet, microwaved cooking and refrigeration but they still "gotta catch 'em all!"
We were fortunate that even though the power-outage went 3-4 hours over time (apparently the pole-replacement was too big for the hole dug) it was not as cool as it had been, getting down to 5oC at nights, as all our inside heaters are electric. However, running the stove, boiling water in the PowerPot for hot drinks as well as generating power, and our collection of candles and lanterns for lighting.
Outside, I ran our BioLite thermoelectric stove much to the delight of Tactical Baby, who insisted in roasting marshmallows over the flames, whilst I charged yet another Lithium 4400 battery and phones directly. I cut wood to run the BioLite, as it only takes short sized lengths of wood and twigs before dark set in. We were preparing to cook by candlelight when the power came back on.
With good use of ambient light, not opening our fridges and freezers, and gas-cooking and water, we were hardly inconvenienced, and with my collection of thermo-electric power sources, we has device-running power aplenty.
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.
In the lead up to the Hurricane Sandy landfall that hit the US East coast hard over Halloween 2012, I saw a great looking multi-function stove come past my friends feed, and it immediately took my interest. This is the BioLite Camp Stove and here's why I want one.
The photo below shows a bunch of power-deprived NYC folks charging their phones at a street-side kiosk running several of these stoves.
The stove itself is pretty simple. With a packed height of 21cm (8.25") and 12cm (5") wide, weighing 935g (2 lbs 1 oz) It is built to burn sticks, pine cones, pellets, wood chips, or other lightweight, small fuels and the frame will support a bot of up to 3.6kg (8 lbs) or 3.6L (1 gallon) of liquid.
The real magic however, is that the orange module on the side is a thermoelectric generator.
As well as being fast to boil (a reported 4.5 minutes to boil 1 liter of water) the fire has a calculated 3.4 kw (lo) 5.5 kw (hi) peak output, which the thermoelectric generator can output via USB as Max continuous: 2W @5V, Peak: 4W @5V which apparently is sufficient power to charge and run most USB-chargeable devices including smartphones, GPS units, flashlights and the like.
Some reviewers have noted that these aren't especially efficient and I am looking forwards towards my first venture in this regard, with my tPOD1 Kickstarter on its way soon ... but the large scale BioLite, combining both power generation and cooking facility in one, sparks a distinct interest in my multifunction wish-lusting!
