It’s not unusual to find rust around saltwater, but now the pairing might actually be useful. Researchers at Caltech and Northwestern University have found that electricity can be produced when saltwater flows over the top of thin films of ru… Continue reading Salt water flowing over thin layers of rust generates electricity
[Jeff Rodriguez] has been busy testing a feasible DIY method for rifling a barrel and has found some success using salt water, a power supply, wire, and 3D printed parts to create the grooves of rifling without the need for any moving parts or cutting tools. Salt water flows between the barrel’s inside surface and a 3D-printed piece that holds wires in a precise pattern. A current flows between the barrel and the wires (which do not actually touch the inside of the barrel) and material is eroded away as a result. 10-15 minutes later there are some promising looking …read more
