In March 2012, the Deepsea Challenger reached the ocean's deepest point at about 7 miles (11 km) below the surface of western Pacific. Weighing 12 tons (11,000 kg) and measuring 24 feet long (7 meters), it can withstand about as much pressure as the equivalent of three SUVs sitting on your toe. The sub, designed by filmmaker James Cameron, cost $8 million to create. It has digital 3-D cameras to document the deep.

Baxter is a new breed of industrial robot. Rodney Brooks, who helped invent the Roomba vacuum cleaner, built Baxter for light, repetitive tasks like packing and sorting. At $22,000, Baxter is cheap compared with other robots that perform the same types of tasks. This gives small businesses greater access to electronic help. Baxter is also easy to use, so people can put it right to work.

Marcin Jakubowski built a tractor in six days. Then he told the world how to do it: He posted the designs, the budget, and a how-to video online. Now Jakubowski, founder of Open Source Ecology, is making free instruction kit for low-cost version of 50 important machines. If anyone anywhere can build them, he says, "we can unleash massive amounts of human potential."
