In any contraption with moving parts--automotive engines, industrial machines, a countertop juicer--some degree of energy is lost as heat to friction. That loss can range from the relatively small amount lost by a single juicer, to the collectively huge amount lost each day by, say, all of the cars in the world (or all of the industrial machines used to manufacture them). A new nanotech solution could change that via a new lubrication technology that can cut friction by 55 percent.

NASA's Mars Reconnaissance Orbiter, the largest and most powerful spacecraft ever built, is bound for the Red Planet this August. Watch an animation of the craft as it speeds into martian orbit at 25,000 mph, uses atmospheric friction to slow itself down to 300 mph, and settles into its final orbit less than 200 miles from the planet's surface.
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.
