” 6. Find Potable Water“Don’t exert yourself in the heat of the day,” Sanders says. “You may lose more water by sweating than you’ll gain by digging.” Ravines and valleys are carved by running water, so head for the bottom. In deserts, with only occasional flow, look for cottonwoods, willows and other light-green vegetation that grows in wet areas. When the sun or moon is low in the sky, scan the horizon for reflections that may reveal the location of small pools. (Don’t worry if the water looks scummy. Waterborne illnesses won’t kick in for at least three days; dehydration can kill in a single day.) Collect morning dew by wiping grass with a cloth, then wringing out the water. If you have plastic bags, wrapping them around the boughs of deciduous trees yields 1 or 2 ounces a day. “
” Scientists are developing new materials which could one day allow people to print out custom-designed personal electronics such as games controllers which perfectly fit their hand shape.
The University of Warwick researchers have created a simple and inexpensive conductive plastic composite that can be used to produce electronic devices using the latest generation of low-cost 3D printers designed for use by hobbyists and even in the home.
The material, nicknamed ‘carbomorph’, enables users to lay down electronic tracks and sensors as part of a 3D printed structure — allowing the printer to create touch-sensitive areas for example, which can then be connected to a simple electronic circuit board. “
