Aboard oceanfaring vessels, real estate is naturally limited. But communications are vital, presenting something of a conundrum for a ship’s communications crews: where to place all the large antennas necessary for long-range (and often encrypted) communications. So U.S. Navy R&D lab SPAWAR Systems Center Pacific (SSC Pacific) engineered a clever scheme to turn the ocean’s most abundant resource into communications equipment, making antennas out of geysers of seawater.

Since 2001, more than 13,000 American soldiers have been killed or maimed by landmines or improvised explosive devices. Civilians included, landmines kill or injure an estimated 20,000 people around the world every year.

Picture this: A massive destroyer receives the location coordinates of an enemy headquarters more than 200 miles away. Instead of launching a million-dollar Tomahawk cruise missile, it points a gun barrel in the direction of the target, diverts electric power from the ship’s engine to the gun turret, and launches a 3-foot-long, 40-pound projectile up a set of superconducting rails.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
