Healthy Eating. 7.
There are advantages to urban survival. Anywhere you look there are items in trash cans and dumpsters that can be used to improve a survival situation. Cardboard boxes can be used for shelter, newspapers can be used for insulation and to the practical survivor another persons trash can be a treasure. In this case we will use a coffee can to build a stove. Whether you call it a hobo stove, can stove, or just a survival stove, this is a cheap effective way to both cook and stay warm.

The bottle filters out objects larger than 15 nanometres.

Pritchard presented a prototype of the Lifesaver at 2007's DSEi London, where the product was named "Best Technological Development". Pritchard's entire stock of 1,000 bottles sold out within four hours of the presentation. Life Raft Makes Its Own Drinking Water (5 pics) Imagine this: Your ship is sinking.
You abandon ship with nothing but the clothes on your back, and you're thirsty, really thirsty. Lucky for you, you've arrived on-board the SeaKettle, a life raft that has the ability to desalinate salt water... The process starts by pumping sea water up to a Gortex covered reservoir, where the water is subject to evaporation. The evaporated water then hits the top canopy and condenses, filling the four pockets around the raft with fresh drinking water. The Gortex cover over the reservoir allows the vapor molecules to escape, but holds in the larger liquid molecules, preventing the pockets of fresh water from becoming contaminated by the sea water.
