battery powered water bottle
I'm interested in possibly modifying a water bottle with an attached battery and some heat coils, so that it could slowly melt snow in to drinkable water. When I hike during the summer I carry little water because I'm refilling from streams regularly, and I'd like to do the same thing during the winter. I don't normally build things on my own, but in this case I can't find any product like this. I recognize that doing this requires quite a bit of power, so I'm not sure if it will end up being feasible or not. I'm willing to carry quite a few batteries, however. For a big mountain ascent, it's not uncommon to carry 4-5 liters of water, so we're talking about 10 lbs of water. So even if I had to swap out batteries a few times, it would still be worth it to do that. Any thoughts on the feasibility of this idea, and if so, how to proceed with it?
