High-Speed Data Transfer Over ... Mud

An anonymous reader writes "You might have laid Ethernet through some pretty aggressive environments, but how about through a 4-inch diameter steel pipe immersed in electrically conductive mud at pressures up to 1000 atmospheres, temperatures up to 150 deg C, and with vibrational accelerations of hundreds of g? The Department of Energy has announced the invention of a system to allow data transmission up to 1 Mbit/s along drillpipe. That might not sound too fast, but the current technology uses some pretty neat electromechanical engineering to get ... 10 bits per second (on a good day). This will revolutionize the oil industry's ability to see where its wells are going and steer them into pockets of oil."
