Welcome to the water-fueled salad-spinner cake box. Here's a muscle-free salad spinner that works from the power of a sink faucet and rotates your salad greens faster than the manual version no matter how much muscle you put into it. Rick Crammond based his spinner on a design invented by Nikola Tesla using his CD Turbine. The turbine combines CDs or DVDs, their spindle case (or cake box as it's sometimes called) and a bunch of magnets. Using your faucet or garden hose, you can spin your greens at 1,000 rpm, giving you superbly dry greens in seconds.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
