Small Comforts


Our society had long been spoiled with all the gadgets that we took for granted and used every day.  Heaters, televisions, lights, toasters, microwave ovens, stoves, tools, computers, VCRs, if it could run on electricity, we used it.  Many of these items were readily available for the cost of just a little trip and our time.  All we had to do was go pick them up.  Videos and DVDs would get us through the long winter nights.  We could still use computers, but there was no longer an internet.  There were no operating phone lines to carry the signals and in this isolated location there were no telephones anyway.  These things required small amounts of energy, but a stove, heater, toaster or microwave required much more.  What we needed was a reliable and adequate source of power.

We had considered putting woodstoves inside each cave and finding some method to vent the smoke outside and bring fresh aid inside to feed the fire.  But burning wood, made smoke; smoke meant visibility.  When one is hiding from one’s enemies, sending smoke signals is not an option.  We might as well have put up a sign saying, “Here we are!”  

Our solution to this problem was quite simple, in theory.  In practice, it took some engineering skill that we developed as we went along.  We would produce our own electricity for all our needs, heating and the rest.  At first, we thought we could use generators.  Generators were quite common and available in most hardware stores so getting them in large numbers was not a problem.  Each small gas generator was large enough to operate a single 1500 watt heater, and used a lot of gasoline. Each cave required at least two in order to meet our combined winter needs of both heat and entertainment.  But as we soon learned, although, mostly smoke free, they were noisy, especially the commercial ones.  Noise, was next to smoke in terms of attracting attention.  Little did we know at the time, but we had shopped for generators at the wrong store.  There were other, more powerful ones, that could have easily met most of our needs that ran much more efficiently and quieter.  But, live and learn. 

Wind turbines were smokeless, and as far as we knew, were also silent but for the noise of the wind passing through the blade as it spun around.  There were enough stores around that sold them and occasionally as we passed a farmhouse on a country road, we noticed them there, too.  Since these were already set up and running, they were the first ones that we acquired.  But the power produced by a small wind turbine was even less than a gas generator.  We would need a lot more of them to produce the same amount of power.  

There was one aspect of all of this living like cave dwellers that took me awhile to get over and it is important that the reader understand.  The kids never really complained.  I was sure that they had buried their feelings over the loss of family and friends, but it seemed as if they were putting the past behind them and seeing this country living as an adventure.  It was as if they were on an extended camping trip or they were pioneers discovering a new land.  Every difficulty they encountered they accepted as a challenge and lent all their efforts to overcome it.  Remarkably, they got along most of the time, too.  This had not always been the case in the classroom where a disagreement could easily arise over some silly comment and tempers flare.  I supposed that it had something to do with the concept of “we are all we have,” so we need to make the best of it.  It was this attitude that drove them on, for example, to complete projects like this one.

There was little to no wind to speak of in the valley, beneath the escarpment, so we placed the turbines at the top of the escarpment and ran the power cables down over the cliff, directly to our site.  Being acrophobic, I was not able to help out much.  I couldn’t bring myself to stand or even crawl close to the edge of the escarpment.  Neither could I help by placing attachments for the cables down the rock face.  This was left for the brave, adventurous, younger folk.  I just stood at the bottom and sweated for them all, my heart stopped in mid beat until each one was safely on the ground.  And it seemed like I had good reason to fear, as I watched Lise, who being a little shorter than the rest, was not able to grab onto the same handholds as the taller Bruce.  At one point, it seemed as if she was going to be stuck on the cliff, not able to go up, or climb down.  Three, four, maybe five times, I stood in horror as she swung her body from side to side while she attempted to reach the hand hold that the others had clutched with little problem.  At her height, she was sure to be badly hurt, if not killed if she fell.  I held my breath as she again swung back hard, then seemed to push herself even harder in the opposite direction.  I let out the breath I had been holding as she finally managed to find and grip the ledge.  Tammy, who was not into death defying feats, had remained on the ground near me.

In spite of the thickness of the wire we used to transmit the power, it didn't provide what we had hoped until we incorporated transformers.  Why we didn’t kill ourselves in the process is still a wonder, but we eventually overcame the challenges and were able to operate most appliances safely.  Initially, we ran separate wires to each room from a single wind turbine, but later combined the four into one circuit that snaked its way to its own room crowded with batteries from which all of our rooms were serviced.  Although I didn't understand exactly how direct current could be transformed into alternating current, I was aware of, and actually had purchased such a device several years before to use in my vehicle to allow me to use my computer or charge batteries for my camera from the cigarette lighter.  I supposed that this system was similar to, though of a higher capacity and strength.
