I'd find stories about this interesting too. I took a couple of weeks to camp by a lake and attempt to learn kitesurfing, while working in the evenings. In the test run with my solar panel at home, everything worked well - charge batteries during the day, work at night with a dim screen. In the wild I soon found that mobile internet power usage goes up dramatically if you're a long way away from the mobile tower, it's hard to work without a decent seat (I took my motorcycle, so didn't have a car to sit in), and the light was just too bright in the days/evenings. Next time I'm going to try with a van =D. Also, to answer a couple of the other questions: - Sand wasn't generally a problem for me, except I blew up my fancy 240/12V laptop power adaptor when some wet grit got into the connectors. - Sunlight was only really a problem in regards to battery power; screen brightness is a big contribution to power usage, so there's a trade off.
