UCF Oblique Wave Detonation Engine

There are scores of researchers working on new ways to propel aircraft to supersonic and even hypersonic speeds. A team at the University of Central Florida is among them, and they've recently made a breakthrough by building a hypersonic reaction chamber for jet engines. The system harnesses the power of a detonation — normally chaotic and destructive — keeping it stationary and stabilized while using the shock wave for propulsion. As a result, a full-scale version would enable air travel at speeds of Mach 6 to 17, which is more than 4,600 to 13,000 miles per hour, and could also be used in rockets for more efficient space travel.

Zager Easy Play Guitars

Denny Zager rose to fame as part of the duo Zager & Evans in the late '60s, yet it's his guitars that have perhaps had the largest musical impact. Having applied his know-how to easy-to-play acoustic guitars, he's retiring this year — but is leaving with an oft-requested black lacquer version of his cutaway ZAD900CE model. With a lower string height, greater distance between the strings, a slim neck, and an intelligent bracing system to help movement, it's imminently playable, producing the same rich, warm sound that's made it a beloved favorite. Each lucky buyer will also receive a robust bonus package that includes a digitally humidified case, extra Zager PillowTouch strings, three carbon-tipped picks, a truss key, a stainless capo, a leather strap, a digital tuner, and a free lifetime membership to Mr. Zager's guitar lesson library..
