Outage musings

Posted on by

We had a couple very, very brief power outages here over the weekend. They didnt disturb my life too broadly because 1) they were of fairly short duration..only an hour or so, b) I’ve long reconciled myself to the notion of how to live with minimal or zero grid delivery, and III) I have some backup systems in place.

There’s been a bit of a Streisand Effect on infrastructure disruptions. Our electrical, water, gas, and other utility distribution networks have always been, for the most part, unguarded and completely vulnerable to even the mildest attack. But…such attacks, at least as reported, were few and far between. But when they do start getting reported, it gives someone somewhere the bright idea to go cause some mayhem and they wind up shooting up a power transformer, busting up a rail switching system, or punching a hole in a pipeline just because.

And, as we’ve made our infrastructure more connected and more complex…well…As the patron saint of engineering said:

The point being, in this world we live in…where everyone with a grudge, real or imagined, is just a .30-06 or a backhoe away from turning off the power and water…things like electricy, gas, and water are going to be less certain than they are now. Add in the age and inadequacy of many region’s infrastructure and you have a recipe for more frequent disruptions, not less.

As far as electricity goes, years ago I evaluated what I considered absolutely necessary for my security and safety in terms of power. I have kerosene and propane for heating, lighting, cooking, and that sort of thing. My critical must-have electrical needs are to keep my frozen food frozen and to keep me security cameras camming. Thats about it. And those needs are easily met with a little ol’ EU2000.

My smaller electrical needs are things like flashlights, radio batteries, cell phone charging, and that sort of thing. Those are met pretty easily by rechargeable batteries and a small solar panel..although I can recharge off the EU2000 if I really need to.

After the freezer and security cams, anything else is a luxury. But the important thing is that at some point you need to sit down and examine what exactly are your must-have’s that will require electricity. For most of us, its going to be freezers. For some it’ll also be well pumps and maybe pressure tanks. Some folks in particular situations will also need sewage pumps. Or perhaps you’ve got a medical situation that requires electricity for a treatment device. There’s no shortage of things that are ‘must have’s when it comes to electricity. You just need to figure out what yours are and then plan accordingly.

As I said, power outages are just a minor hiccup for me…I know exactly what my needs are (freezer and cams) and what my ‘I can get by with less’ things are (everything else). But you have to at least have an idea of what you do and don’t need before you start shopping around for things like generators and kerosene lamps.

 

Saturday outage

Posted on by

An interesting day. Was on the computer this morning, going through emails, when without warning I hear the noise of the computer backup power supply kick in and start beeping. A moment or two later it was joined by the UPS for the security system. That’s pretty much the song of a power failure.

Ok, not a big deal. Its the beginning of the day, so lighting isn’t really an issue. What is an issue is determining how big and widespread this thing is. There’s a big difference between a squirrel tap dancing on a transformer plunging my little neighborhood into a blackout and someone EMP’ing my local power generation facility.

Pulled my Icom R6 out of my Bag O’ Tricks and dialed up the local police/fire scene. No chatter indicating a town-wide outage but lets go take a look ourselves. Slipped the Glock into its holster, grabbed an MP5 ‘just in case’ and headed to the truck. A quick drive around the neighborhood showed that, indeed, the power was out. However, when I got to the busy main street I could see far enough down the street in either direction to see active traffic signals. SO..its a localized outage, not the opening act for something more sinister.

Returned back to the house and listened to the scanner some more. Cops reported various traffic signals as inoperative and were directing traffic where necessary. All in all, it was something that didn’t require any real escalation of alert status. So, since we have an actual-but-well-in-hand ’emergency’ going on lets see how ready we are.

Biggest issue: the UPS for my security cameras faded almost instantly. After a couple minutes the cameras all went dark. This was a bit surprising. While there are about a dozen cameras, their draw shouldnt have been enough to wipe out a constantly-charged battery in less than a few minutes. However, this UPS is close to ten years old so perhaps it’s simply time to replace it. Replaced it with two UPS’ later that day.

The Icom R6 performed quite well within its design parameters…and those parameters are for a compact radio scanner. Since I was not constrained by size requirements, due to being at the house, I really should have had a larger, more eay-to-use unit available. I have a few handheld Bearcats of varying vintage laying around but this reinforced that I need to have a more modern full-size unit around. So, there’ll be some research on that and then a quick trip to Amazon.

As has been typical in 90% of the blackouts I’ve experienced here, power was restored within an hour or so. No need to break out the Honda EU2000 to top off the freezer or anything like that. But, of course, it’s there if I need it.

Of all the systems here in the house, the security cams are the ones that have the least amount of reasonable alternatives for a period of power disruption. I have alternatives for heating, cooking, and lighting, but there is only one option for keeping a video security camera system operational and that’s electricity..either stored or generated.

In practice, the UPS for the security system only has to run the system long enough for me to get the generator up and the system plugged into it. Setting up the generator from storage and getting it running is, at most, a fifteen minute job. Closer to ten in the warmer months. Any UPS only really has to last long enough for that period of time. But, no one ever really complained that their batteries had too much capacity. I suppose it might be worth investigating just building a larger capacity backup system with a few AGM batts, a charger, and inverter dedicated to just the security cams.

That was, thus far, the most interesting thing to happen here today. A learning experience for sure. If it had gone on more than a few hours it would have been a bit more interesting but those kinds of failures a few and far between here in town. But, of course, that doesnt mean they won’t happen or that I shouldnt be prepared for them.

Goal Zero stuff

Posted on by

I try to standardize on batteries for obvious reasons. Broadly, I lead a life of AA- and D-batteries. But as of late, it seems like more and more devices use rechargeable batts that are recharged through a USB connection of some kind. I’m kinda liking this from a survivalist stanpoint.

There are plenty of chargers out there to recharge AA and D batts from various sources, I recognize that. But it’s just so much easier to order up a small folding solar panel, plug in your USB cable, and start charging your device. The things that, most notably, come to mind are cellphones (which have tremendous utility even in a world without phone signal), flashlights, small radios, and that sort of thing.

I’ve also a few devices that can use either available batteries or use built-in rechargeable-through-USB. For example, the Fenix PD35 that I picked up a while back will run off a couple CR123 batts or can be run off its rechargeable battery. Thats pretty handy.

I had a small folding Goal 0 panel that, while handy, has a rather small footprint, and when it comes to solar charging the more panel area you have the better. There is, of course, a point of diminishing return…you want a panel thats large enough to get the job done but, at the same time, you want a level of portability and compactness to make transport and storage a bit easier. Seems like a reasonable idea, yes?

Goal Zero sometimes has ‘road shows’ at CostCo and they have some very interesting stuff. I have a bunch of their daisy-chainable LED 12v loights that I highly recommend. I decided I wanted to get a little package that wouuld charge AA (and AAA) batteries, charge a phone battery pack, and could charge other USB-connectable devices. By charging AA batts that gives me a lot more use to handheld GPS, AA flashlights, radios, weaponlights, weapon sights (for the ones that run on AA or AAA), my ICOM R6, and a host of other AA-batt compatible devices.

So, off to Amazon for:

Hurricane Sandy left some folks with power, and they became very popular very quickly. I'm trying to avoid this sort of social clusterbomb.

Hurricane Sandy left some folks with power, and they became very popular very quickly. I’m trying to avoid this sort of social clusterbomb.

A couple things to note… The Guide 10 battery charger has a USB port to allow you to use it to charge your USB devices. So far so good. However, it is 5v 1amp vs 5v 3amp of the Venture power bank. What this means is that while the battery charger, with a load of recharged batteries in it, will charge your phone or device…its gonna take a while.

The Venture is 5v 3amp so its gonna charge your toys a good bit faster.

Both devices can be charged from other sources, such as a wall outlet using a USB cord and plug-in. Both devices also incorporate a basic power level indicator and also have an LED flashlight feature. Handy, but shouldnt you already have a flashlight?

I drained all the batteries in the Guide to 0% and did the same with the Venture. I set up the panel in the sun, tucked the Venture or Guide behind the panel in the shade to keep it from cooking, and left it while I went to work. When I got back in the afternoon, the devices indicated a full charge. (Note: they were not charged at the same time. The panel has one USB port, so I alternated.)

The panels themselves seem fairly durable. I’d try to avoid bending or flexing them (although there are flexible panels out there). In terms of compactness, the panels, when folded up, are about an inch or so thick, and takes up a footprint slightly smaller than a sheet of paper.

You can, of course, plug whatever device you are trying to recharge directly into the panel’s USB port but then your device is subject to the vagaries of uneven charging as the sun may or may not experience some transitory cloud cover. (And, wow, my brain parses ‘vagaries’ completely different than what it means when it see it on screen. Gotta check that word twice.)

Really, the best option, it seems to me, is to use the panel to charge your storage device..batteries or power bank….and then charge your device from those. And, of course, you can charge your other devices from that power bank as well.

So..I’ll play with this stuff and see how it goes but so far it seems like an acceptable way to keep my small devices topped off when grid power just isnt in the cards.

 

Generator Day

Posted on by

Today was Generator Day. Interestingly, it is also apparently Generator Day in a large part of the southeast US.

The purpose of Generator Day is to, periodically, run the generator under load for an hour or so in order to make sure everything functions and doesn’t get stagnant or stale. Usually I fire up the EU2000, plug in an electric leaf blower, and do some yardwork.

It’s been a while since I started this thing up. (Bad survivalist!) I had actually forgotten the startup procedure. Fortunately, part of my generator prep plan includes copying the startup/shutdown instructions from the .pdf, printing them out, putting them in a sealed page protector, and attaching them to the generator. As a result, I quickly had my memory refreshed. Started on pull #9.

This is, I believe, year nine for this particular EU2000. According to the run meter I put on this thing when I bought it, I’ve run it for about a total of 30 hours. Thats some pretty low miles.

The EU2000, when I purchased it, was the big thing in portable generators. Since then, upgraded versions have come out and when I get another spare or two, I’ll get the upgraded version. But, so far, for nine years this thing has been sitting quietly in it’s Hardigg case awaiting the infrequent power outage. Been quite pleased with it so far.

Of course, no man is an island and not piece of expensive gear is without support materials. The Hardigg case that houses the generator also contains a cable lock, spare air filters, printed directions, heavy duty extension cords, spare fuel cans, PRI-G, etc, etc.

In the nine years I’ve had this thing I’ve only needed to genuinely use it twice. Both times for only a few hours. And both times I felt pretty darn smug as I sat there with cable and internet as my neighbors suddenly became involuntary Luddites.

So, if you haven’t gotten one yet….thumbs up on the Honda EU series.

Black Start

Posted on by

An article from Yahoo about a state-sponsored data breach that may have handed over some interesting info to the Chinese/Russians.

“For example, it’s reportedly possible the hackers accessed Black Start, the detailed technical blueprints for how the U.S. would restore power if there was a major blackout. If that was indeed the case, Russia would theoretically have a list of systems it could target to keep power from turning back on.”

A government plan for restarting power generation? Interesting. Makes sense when you think about it…but I’d never thought about it before. Shades of “One Second After“. (WOrth reading, btw.)

As the saying goes, “it takes money to make money”. Apparently the same is true, to some degree, in power generation. As I read it, previous plans for restarting an offline power plant assume you’ll be able to have power from elsewhere where the grid is up. But, if the entire grid is down…well…you can’t start up your power plant if you can’t even turn on the lights in the control room.

The solution, it seems, is to either have enough capacity in your onsite generators to get the plant up and running, or get your electricity from a source that will continue to provide..such as hydropower.

What I find interesting here is that .gov had a planned response in place for a grid-down power plant restart procedure..and now that the playbook for that has fallen into enemy (and make no mistake about it, thats what the Chinese are) hands they know how to create that grid-down situation and disable our ability to get past it. All in all, to my unstrategic way of thinking, that seems to have just made the possibility of an attack of some kind on the national power system more likely.

Very cursory googling shows that apparently the current plan (or one of them) is RADICS.. Apparently the .gov has, in the last two years, stepped up it’s research into preparing against cyberattacks that target energy infrastructure. Interesting, that.

Remember the old days when targeting a nations energy infrastructure involved a B-52 instead of a laptop?

 

 

Checking batteries

Posted on by

As the year comes to a close, I’m wandering around the house checking batteries in various devices. About a year ago I had a MagLite self-destruct when the batteries crapped out. The usual scenario….flashlight doesn’t work, you unscrew the tailcap, and when you finally get it open the guts of the thing are full of the corroded guts of a battery. Freakin’ hate that.

So, I decided I’d keep a list of what devices I kept around in a state of readiness with batteries already in them, and I would periodically inspect those devices so that if the batteries started to go Tango Uniform I might catch them before the device was irrevocably damaged. As it turned out, thus far, no batteries have gone south this year. BUT….that doesn’t mean they won’t and it doesn’t mean that periodic inspections are a bad idea.

So, I’ll update the little sticker I have on the devices to reflect the periodic inspection and tuck the devices away in their usual spots.

My experience has been that I have had absolutely no problems with lithium batteries. I’ve yet to have one leak and ruin a device…for what those stupid things cost, I should hope they’d be more stable than the current crop of Duracells. It’s at the point where, for mission critical or expensive devices, I won’t use anything but lithiums. I’d rather ten bucks for a pack of lithium batteries than $175 for a new GPS unit, y’know?

So, while your swapping batteries for all the kids toys this holiday season go check your own toys and make sure the batteries didn’t crap the bed.

Lighting

Posted on by

Last week I plugged in the 12v desk lamp into the rehabbed Goal 0 battery to see how long it would run. Well, today is about a week since then and the little battery meter says it’s down to approximately 40% charge.

So, seven days at 24 hour usage means I could run this thing for six hours every night for a month. Or eight hours a night for three weeks. Thats a not inconsiderable amount of time to have ‘normal’ lighting.

Sometimes it’s hard to wrap your head around something like an economic collapse, a gigantic earthquake, a global pandemic, etc, but pretty much everyone can relate to a blackout or loss of electricity because we’ve all experienced it before at some point in our lives.  A power failure is probably the ‘disaster’ that the majority of people can relate to. Not everyone thinks keeping a case of 5.56 and years worth of freeze drieds is a good idea, but pretty much everyone has a flashlight at home.

Anyway, as I mentioned in the previous post on the subject, I like keeping a couple battery-in-a-box type of items on hand so that I can just set up a light source and pretty much not have to worry about it. I’ve yet to experience the outage that lasts more than a day and at the moment I have the resources to not have to sit in the dark for an entire month.

Gotta say, man….Ii remember when LED lighting started to be a thing. I recall thinking that if it delivered the lighting they promised at the low-usage rates they calculated it would revolutionize emergency lighting and low-power lighting systems for remote locations. Apparently it lived up to the hype.

Goal 0 Extreme 350

Posted on by

I have a couple ‘battery in a box’ setups around the house. I have an ancient (pre-Y2K) ConSci powerpack that has, rather unbelievably, held up for the last twenty years. And, as of late, I picked up a battery jumpbox that ran an LED desk lamp for a week. That told me that as far as emergency lighting needs go: a) anything other than LED’s is a remarkably foolish choice and b) assuming six hours of use per night, I can light the house up for a month with a lamp and a charged battery. So, the logical conclusion was to get a couple lamps,a couple batteries, and keep them charged. This I have done.

Now, the emergency lights I use are from Goal 0. I have fabbed up my own in the past, and I’ll probably do that again, but Goal 0 had some nice, simple, daisy chainable lights. Goal 0 also makes various battery packs. I was gifted a dead one last week, along with a Goal 0 panel to charge it. And thus begins our tale.

So I was generously given a Goal Zero Extreme 350…a discontinued batterybox type of product. It featured Anderson power pole connectors, charging regulator, charging input, fuses, and a battery meter. Really, you could put together the exact same thing for less than what Goal 0 charges but some of us are not terribly handy with tools and prefer an out-of-the-box turnkey solution.

Anyway, this thing had sat in storage and was deader than Hillary Clintons presidential chances. I let it sit on the supplied charger for a couple days and got no joy at all. Clearly the long period of non-use, and slow discharge (because the battery meter is on all the time), led to the sealed lead-acid battery becoming unrecoverable.

But..I liked the other features. Perhaps Goal 0 has a replacement for this battery? Nope. And the replacement batteries they do sell are $$$. So….off to the itnernet. Which is where I found this – directions on DIYing a replacement battery off Amazon. Since my basis was $0 in this, I didn’t mind dropping the coin for a new AGM battery to replace the dead SLA battery. So, ran off to Amazon and ordered up the suggested battery which was an exact dimensional fit, gives me the advantage of AGM, and was an extra 5 amp/hour. Followed the instructions and – voila – brought it back to life. I’ve got my desk lamp hooked up to it to see how long it’ll run on a full charge, and then to see how long it takes to charge it using the panel. I’e no doubt this thing willrun the lamp for at least three or four days…and probably longer. It’ll give me one more self-contained lighting unit to distribute where needed next time the power goes out. And the price was right.

Generator day

Posted on by

Rather nice day out there today. Good day to crack open the Hardigg case where I store the EU2000 and make today into Generator Day.

I’ve had the Eu2000 for about five or so years now and I have been quite pleased with it. There have been a fw short-term outages where I’ve had to run it for a few hours and I’ve been very pleased with it. I have no real need to run the entire house, rather my needs are extremely simple..keep the freezers freezing, and the router routing. Thats pretty much it. Heating is taken care of with the kerosene heaters, lighting is taken care of with the Goal0 lights and some AGM batteries, and everything else is mostly a non-critical system.

Although the EU2000 has been a reliable piece of gear, I will probably at some point get a second one. There’s a lot of piece of mind to not having all my eggs in one basket and the two generators can be daisychained to provide higher output should the need arise.

When I got mine, I think they were on sale for about a grand. They’re a bit more nowdays but still, in my opinion, a very good purchase. If you decide to get one, don’t forget all the ancillary gear that goes with them..air filters, oil, gas can, fuel funnel, heavy-duty extension cords, cable lock, etc, etc.

More LED lighting experimenting

Posted on by

So, if you recall, late last year I had a post up about picking up one of those handy-dandy battery jump-packs at CostCo. They’re a fairly simple, though not perfect, solution for people who are just not inclined, mechanically or motivationally, to whip up their own battery-in-a-box.

After that, I got the curious interest of wondering how long my converted DC LED desk lamp would run on the jump-pack before failing. (The short answer was at least a week 24/7, which, at 6 hours per evening comes out to a freakin’ month of light. Probably more…I quit the program after a week figuring I had enough info.)

It was, to me, a very useful experiment and showed the potential for some tremendous utility from those devices in case of emergency. But…it’s very localized lighting. Its a desk lamp, after all. Which means it’s ‘area of effect’ in terms of illumination isn’t very large. So…what if……….

Was up at CostCo and they have a 4′ LED shoplight that looks similar to the old-style fluorescent shop lights we’re all familiar with. Now, lets state right up front that these were not the really high output LED worklights that are avaialble…for $25 the box says you get about 4000 lumens. Ok, thats fine…what I’m after is the ability to light up a room in a manner that looks virtually identical to what it looks like when the power is on, and not like someone pulled the housing off a MagLight and set it up on a file cabinet in the corner.

Here’s the rub…its set up for AC current, which means that I have to plug it into the built-in inverter on the battery pack. Problem is, the LEDs are DC to begin with…. converting DC (battery) to AC(fixture) to DC (LEDs), as I understand it, isn’t as efficient as if it was just straight DC to begin with. Fortunately, the internet is not without a supply of posts and DIY from people who wanted to do exactly that…. so, I may dig out my snips and electrical tape and see what I can do. But, for now, I’m curious to see how long it’ll run off the battery pack.

I still have these guys sitting here and it would be interesting to put them together to form a self-contained emergency backup lighting system for the storage area where all the emergency gear is.

I have no illusion this thing will run as long as the desk lamp did, but that lamp ran over 168 hours…this thing, on the ther hand, ran for three. Three. I suspect that the actual runtime would be several orders of magnitude longer if it were DC-DC. So….some tinkering is in order.
