Hypersonic technologies have the potential to provide the dominance once afforded by stealth to support a range of varied future national security missions.
Extreme hypersonic flight at Mach 20 (i.e., 20 times the speed of sound)—which would enable the department of Defence to get anywhere in the world in under an hour—is an area of research where significant scientific advancements have eluded researchers for decades. Thanks to programs by DARPA, the Army, and the Air Force in recent years, however, more information has been obtained about this challenging subject.
DoD’s hypersonic technology efforts have made significant advancements in our technical understanding of several critical areas including aerodynamics; aerothermal effects; and guidance, navigation and control,” said Acting DARPA Director, Kaigham J. Gabriel. “but additional unknowns exist.”
The IH program is designed to address technical challenges and improve understanding of long-range hypersonic flight through an initial full-scale baseline test of an existing hypersonic test vehicle, followed by a series of subscale flight tests, innovative ground-based testing, expanded modeling and simulation, and advanced analytic methods, culminating in a test flight of a full-scale hypersonic X-plane (HX) in 2016. HX is envisioned as a recoverable next-generation configuration augmented with a rocket-based propulsion capability that will enable and reduce risk for highly maneuverable, long-range hypersonic platforms.
 
Wall Street Journal - a mounting number of stunning discoveries, inventions and technological breakthroughs that could set off a burst of growth and wealth creation as big as any in living memory.
Michael Malone has a decent list of technologies.
I would include
* Factory mass produced skyscrapers
* Spacex and reusable low cost rockets
* Energy breakthroughs (different forms of nuclear fusion)
* Robotics - robotic cars
* Other mundane singularity technology
The fracking technology that is making available vast new sources of recoverable oil and natural gas in North America is one such breakthrough. But all across the commercial and industrial landscape, there are exciting developments:
Nanoculture: One of the truths of tech is that revolutions take longer than predicted, but they arrive sooner than we are prepared for them. That is the case with nanotechnology, the hot new science story of a decade ago.
Though it has largely disappeared from the front pages, nanotech is only now coming into its own. Breakthrough medicines; genetic research; new materials such as graphene (a lattice-sheet form of carbon used for everything from filters to computer chips); molecular electronics (extreme miniaturization, thus super-small sensors and other devices); and quantum computing (small, superfast supercomputers) have all been announced in recent months. Indeed, the range of emerging applications for nano materials is so wide-ranging and important that, together, they suggest an impending turning point in high tech as important as silicon and integrated circuitry were half a century ago.
