Didn't you know? something like 90% of US military tech originates from the Nazis. They were technological geniuses. Just had a problem with killing people. We got all their gold, per say. Russia probably got quite some stuff too.
Blue Origin (blueorigin.com): Founded by Jeff Bezos of Amazon.com, the company has built a prototype spacecraft named Goddard, a rounded cone shape with four stubby legs. It took off vertically, rose 285 feet and descended successfully in a 2006 test. The company declines to grant interviews but says on its website that "Our first objective is developing New Shepard, a vertical take-off, vertical-landing vehicle designed to take a small number of astronauts on a sub-orbital journey into space."
It was awarded a $22-million NASA contract this year and has a Washington state manufacturing site and a Texas launch complex. www.tampabay.com...

NROL49, interesting possibility. Thanks for your comments!
You bring up valid points about the thrust.
While Boeing claims it wont disturb even sand below it, its hard to imagine.
I hope to come across some other info soon, will post it here when I do.

Scale it down, and we could be riding on hoverboards

Bring it on McFly!
Source: Improving Pulsejet Efficiency
One of the biggest drawbacks of traditional pulsejet designs is the rate at which they consume fuel. Whereas a modern high-bypass turbofan engine of the type used in passenger uses just 0.3-0.4lbs of fuel for every lb of thrust generated, a traditional pulsejet will consume over ten times that amount (3-4lbs) for every lb of thrust it generates. This means that a pulsejet generating 100lbs of thrust will consume over 300lbs of fuel per hour. If that fuel is regular gasoline, we're talking about using 55 (US) gallons per hour! By comparison, even a humble piston engine driving a propeller can generate the same amount of thrust at a cost of just 2 gallons per hour or less.
