Some thoughts on winter boondocking and power consumption

I've been watching where my power consumption is going. Running off just the battery I can turn things on & off and read the ammeter and see what draws significant power and what does not. It surprised me to find my 15 inch MacBook Pro and the portable hard drive I keep my pictures on are by far the biggest power users in the rig. Here's what I'm finding:

Most everything runs off 12 volts.

So that's roughly 15 amp-hours per day to run the house.

I don't use much 120vac (at least I didn't think so). The main thing I use it for is to charge the MacBook Pro and, through it, charge the iPod Touch and iPad. And run the portable hard drive.

So that's roughly 90-100 amp-hours per day to run the computer and WiFi 24/7.

With the sun low in the sky this time of year I can capture only about 20 amp-hours per day from my solar panels. Deducting the 15 amp-hours per day to run the house from that leaves only about 5 amp-hours per day to run the computer etc. That's good for about an hour and a half of computer & internet time.

I had no idea the computer was such a relative power hog. It's a real challenge to keep them shut down - I'm addicted to the convenience of having them always on and training myself to shut everything down when I walk away is proving to be quite a challenge.

[Update] I added a page to my Lazy Daze Section to expand on this power consumption and it's implications for long term winter boondocking. The new page is over at Winter Boondocking.

Night camp

Site 9 - Leasburg Dam State Park, Radium Springs NM

A Siberian dog signal-howl

A camp in the middle of a clear, dark winter's night presents a strange, wild appearance. I was awakened, soon after midnight, by cold feet, and, raising myself upon one elbow, I pushed my head out of my frosty fur bag to see by the stars what time it was. The fire had died away to a red heap of smouldering embers. There was just light enough to distinguish the dark outlines of the loaded sledges, the fur-clad forms of our men, lying here and there in groups about the fire, and the frosty dogs, curled up into a hundred little hairy balls upon the snow. Away beyond the limits of the camp stretched the desolate steppe in a series of long snowy undulations, which blended gradually into one great white frozen ocean, and were lost in the distance and darkness of night. High overhead, in a sky which was almost black, sparkled the bright constellations of Orion and the Pleiades--the celestial clocks which marked the long, weary hours between sunrise and sunset. The blue mysterious streamers of the aurora trembled in the north, now shooting up in clear bright lines to the zenith, then waving back and forth in great majestic curves over the silent camp, as if warning back the adventurous traveller from the unknown regions around the Pole. The silence was profound, oppressive. Nothing but the pulsating of the blood in my ears, and the heavy breathing of the sleeping men at my feet, broke the universal lull. Suddenly there rose upon the still night air a long, faint, wailing cry like that of a human being in the last extremity of suffering. Gradually it swelled and deepened until it seemed to fill the whole atmosphere with its volume of mournful sound, dying away at last into a low, despairing moan. It was the signal-howl of a Siberian dog; but so wild and unearthly did it seem in the stillness of the arctic midnight, that it sent the startled blood bounding through my veins to my very finger-ends. In a moment the mournful cry was taken up by another dog, upon a higher key--two or three more joined in, then ten, twenty, forty, sixty, eighty, until the whole pack of a hundred dogs howled one infernal chorus together, making the air fairly tremble with sound, as if from the heavy bass of a great organ. For fully a minute heaven and earth seemed to be filled with yelling, shrieking fiends. Then one by one they began gradually to drop off, the unearthly tumult grew momentarily fainter and fainter, until at last it ended as it began, in one long, inexpressibly melancholy wail, and all was still.
