Laptop vs. Small Desktop: Best Bang Per Watt?
Deagol writes "Tomorrow I take possession of a remote, wooded lot with a cabin. 15 miles to the nearest utility pole, my electricity options are limited to those I can generate myself, solar being my primary goal. I'm sitting here staring at my power meter, seeing my desktop & monitor draw about 250W -- a non-trivial amount to generate over a 8-to-12 hour workday. I'd be happy with equivalent computing horsepower (1.4GHz T-Bird, 512M RAM, though more is always better). Should I get a small PC with an LCD monitor, or should I get a laptop? Will laptops draw less power (in general), and if so, will losing the modularity and lower cost of commodity PC parts be worth it? I'd love opinions from those who have been in a similar situation."
The batteries in a laptop will give you the flexibility to work independently (for an obviously limited time) of your home's power source. This might come in handy if you have a solar system that has intermittent output or oyou have other high-draw electrical needs.
I spent years living in a place like that. It didn't impede my programming at all. In fact, I believe it improved my software design skills, by forcing me to figure out exactly what I wanted before I sat down to write it.
I think the laptop would be the better idea. Gasoline is costly. If you could get one with a seperate battery charger, and get two or more batteries, you could leave the used batteries to charge at a friend's house or your work and swap them whenever you're out. I have uncertainties about being able to use the solar power for your laptop, depending on your setup.
