Bosch Full Force Technology
When you pull the trigger on a pneumatic nail gun, a valve releases compressed air to push a piston downward and drive the nail. But most nail guns steal some of the piston's force to pressurize a return chamber that shoots the piston back after each discharge. This robs the tool of its full power. Bosch's new line of pneumatic nailers eliminates the return chamber, instead firing a second blast of compressed air to reset the piston. The result is a gun that's 20 percent smaller yet 10 percent more powerful than anything else out there. With its center of gravity closer to your hand, the gun is easier to control, too.

I’m surprised this idea didn’t find application sooner, but I suppose designers were still tied to the concept of the nailgun’s similarity to a real gun (which uses some of the combustive power of the fired round to reset the firing pin.) As a builder, I sure appreciate the added boost!
