This man-packable water pump (no future need for "stairmaster" exercise machine!) and their gold separation accessory will let folks do micro-mining in roadless/trail-less areas without the noise of a genset. This sounds like a gold production job for the post-apocalypse after the planting is done.

Group Buy of stainless steel option?
