When I lived in Vermont in the 1980's and 1990's there were a few times the power was out for 3-4 days. I've lived in northern Arizona since 2002 and the longest outage I can remember is only a few hours.

I've never hear of a wood gasifier stove. How does it work and what does it do?

I keep a UPS (APC--I still have bunch of them ) 1500 watts, backing up my cable modem and switch. An old APC backing up the router, and a pair of 1350 CyberPowers backing up my wife's and my desktops. The laptops, of course, have their internal battery backup. Unfortunately, I don't have a backup yet for my NAS, but I should. I just have to move one into place.
If I remember my college chemistry I believe a wood gasifier turns steam into carbon monoxide and hydrogen. Both combustible gases. The steam has to be super heated under pressure higher than 15 lbs. per square inch.

If you are looking at getting a UPS to run things around the house when the grid goes down, buy one that will black start AKA make output without having to be 'looking at the grid first. Most of them won't, as they need that 60Hz reference to fire up.

As far as our utility goes, it has been very good in terms of reliability until 5 days ago. We had three thunderstorms in succession and lightning took it down each time for some 4 to 5 hours. Luckily there is a 60kW Detroit Diesel genset w/600gal here to keep things going.

The quick overview is that it's a top loading downdraft gasifier. Wood is added and is lit on top. There are vents in the bottom of the 'firebox' that exhaust the CO, CO2, H2, and other gases released from wood as it's turned to charcoal. Those gased are channeled to the top of the stove and combusted. There's a small fan in the bottom that runs from a pair of AA cells that acts like a turbo. It's a very efficient burn and only smokes when it's first lit. They're pretty easy to DIY as well and smaller stoves work fine without a fan. I'll light a fire and report back with performance info. :ugeek:

In the meantime, here's an overview, and a video of a much larger DIY stove:

My old Netgear NAS has saved my bacon many times over the years - it gets pampered.

I started with a cold stove and a quart of cold water from the tap. The stove holds about 4 heaping handfuls of wood chips - I used two. I used a bit of charcoal lighter fluid on four wood chips (yes, on the cement ;) ) and tossed them on top. The stove was lit at 19:10.

It starts making woodgas within a minute or two after being lit. The gas is at full production after 10 minutes, then starts to slow. It brought a quart of water to a rolling boil in 12 minutes.

It was supposed to be my SHTF stove...now it's my "seriously - the power's out again?!" stove. :lol:

The gas composition depends on the material pyrolyzed and the temperature. On one extreme, wood can be 'cooked' for charcoal and the gases are combusted. The wood gas or syngas can be collected and used to run vehicles or generators as well.

I am an Urbanite. All the places I live require real elevators - stairs are not an option except for a real emergency.

If the system fails for 2 to 3 days, I have enough water, food and alternative fuel to be comfortable. If it happens in Las Vegas in mid Summer, you need to bug out. (110 F and windows that don't open.)

I have long considered buying a rural property. My problem is that I don't really want to be there unless it is a SHTF scenario.

One problem is, and this is not a comfortable fact, I am in my mid 60s. The kind of survival experience I had in my 20s in the military taught me very clearly that actual hard core survival is not an old man's game.

If the system fails for the long term (EMP and so forth), then I need to find a crowd that needs a general purpose engineer. I have skills, knowledge, slide rules and books of math tables.

Frankly, other than short term cooking fuel, alternative power does me no good in a high rise.

... and I have an embarrassing minor grade 'prepper' streak. Nothing out of control. But I grew up reading Brad Angier's "How to Stay Alive in the Woods" and really never got over it.

I try hard to avoid the whole 'prepper' conversation. And here is why: if I seriously want to be 'prepared' for the worst possible scenarios, the time and resources required are astonishing. I did a little plan of everything I would need. And it starts with moving to a small town near fresh water and blending in with the community.

All of that is the right idea for a serious SHTF post-apocolapyse world, but it is the worst possible scenario for me if the SHTF(not).

My Bug Out Bag(s) are ready and I know where they are (Hell, I live in 850 sq ft, I know where everything is). My BOBs are pretty good. But they will keep you alive for about 1 week unless you can find food and water. Water, I think I could find. But unless you live WAY out in the back country, if the SHTF, then everyone is going to be looking for the same food as you.

I have reluctantly concluded that if the SHTF in a serious way, I am screwed.

My old NAS was by iOmega. It was an expensive POS that kept failing and iOmega were not particularly supportive. I finally replaced it with a Western Digital which has been stone-cold reliable, but uses the Twonky DLNA protocol, which is a PITA. I had to convert a lot of files and they don't always work. But...it's not the drive.

I did some looking and found that the wood gasifiers can produce a burnable gas that can run a generator or even other engines... and I'm always interested in ways to make power without fossil fuels, instead with renewable fuel.

I associate "Preppers" with the nutty militias in the woods in Montana, but I do believe in contingency planning. I'm probably not going to build a wood gasifier, but I'd very much like to know how...as a contingency.

Well then...seems we're back in the 'first world' at least for a little while. :lol:

YT - I hear you about NAS boxes and infrastructure. I have a 1500VA UPS that coddles the NAS, cable modem, ethernet switch, and router/access point. When power drops, the NAS (the little linux box) shuts down gracefully.

As for prepping and resilience, I figure it's the way our grandparents lived their normal lives. Prepping is just remembering how to do what we should be doing anyway...and that climate change and overpopulation will force us to remember. ;)

Subs - I'm going to buy a bunch of extension cords tomorrow - ok if I run a line to your genny? :think:

My take on prepping in order of importance;
1...Try and stay under the cop & busybody radar daily. Flog yer common sense.
2...Work at staying healthy, and avoid convenience meds (or lay in extras) as you might not find them then. A trauma-level kit and study is good.
3...H2O...have a inviolate supply.
4...Eats, see #2. Always keep a bit of things you really like in the pantry.
5...Keep your home/shelter in good repair. If bugging out is the plan, visit there now & then to make sure it is where you want to go. Fuel on hand in the event you have to drive, fixit stuff if you know how.
6...Arrange some type of currency that won't be devalued. Gold bars might make you feel secure, but try and buy a jar of mayo/make change? Junk silver US coinage is recognizable anywhere, and in denominations easily bartered.
7...Defensive devices and reliable fodder for same.
8...A decent all-band radio. Two-way comm optional.
9...If possible, plan a social banding together--strength in numbers.
