Tesla - The Forgotten Wizard. This is a unique, 10-minute treatise on the political and personal battles
Nikola Tesla fought in his lifetime. It brings out some some of his ideas that I had never heard of.
from salt water? Erie, PA, radio technician
serendipitously discovered that his radio frequency generator could release the oxygen and hydrogen from
saltwater and create an incredibly intense flame. His finding came as a result of experiments he was
performing for a revolutionary cancer treatment that nonintrusively zaps cancer cell with RF energy.
is what MIT robot geeks do during the winter break. Give them a handful of servo motors and teach them the
basics of inverse kinematics and these kids can have fun for three weeks!
GFS Projects Limited Unmanned Aerial vehicle (UAV) GFS13A is able to take off and land vertically; it can
hover at heights up to eighty feet. The GFS UAV uses the Coanda principle to create lift, it has very little
downwash and is aerodynamically stable.
held an Online Engineering Video Scholarship Competition for Undergraduates, with $6,000 in scholarship
awards. Here is the #1 winning video from two dudes at Louisiana Tech University - it is pretty good.
Falkirk Wheel (U.K.) is a one-of-a-kind canal lock implementation that uses a balanced, rotating arm to
simultaneously raise and lower vessels travelling in opposite directions in the canal. 15,000 bolts were
matched with 45,000 bolt holes, and each bolt was hand tightened due to stress factors.
all the rage lately - wireless transfer of energy. Like most new technology concepts, the idea is great, but
practical implementation is the challenge. Magazine articles have heralded it as The Next Big Thing for
powering everything in your house and office - finally eliminating cords and batteries the same way cordless
phones and wireless modems eliminated cables. In this case, going from the lab to the marketplace will take
redefining physics, or glow-in-the-dark houses spewing kW of power to get a AA battery's worth of power to an
Purdue Society of
Professional Engineers team took 1st place in the 2008 national Rube Goldberg Contest.
The task for this year? - A Hamburger Making Machine. The contraptions needed to assemble a hamburger
consisting of no less than one precooked meat patty, two vegetables and two condiments, sandwiched between two
bun halves. Sponsors included some big names like BAE, Daimler-Chrysler, GE, Lockheed Martin, Omega
Engineering, and Rockwell Collins.
Time's 'Teardown TV' performs a
of an HP35s Calculator.
This is a resurrection of the engineering school stalwart of the 1970s and 1980s, the HP35.
An SM-3 missile was fired from the USS Lake Erie in the Pacific at about 7:26 PST and collided with the crippled satellite about 130 miles above the ocean, travelling at 17,000 mph. We have intercepted and destroyed an ICBM equivalent object as it entered the upper atmosphere - on the first shot! ...and some thought the Strategic Defense Initiative (Star Wars) concept would never be realized.
1939 docudrama, "Radio Hams, " is a short film produced by Pete Smith for Metro-Goldwyn-Mayer. Jimmy Mulligan
uses Ma Mulligan's egg beater to wind coils for his radio set. Listen in on the dramas as they unfold.

synthetic seed crystal is placed in a tank filled with a metric ton of supersaturated potassium dihydrogen
phosphate (KDP). As it rotates on a turntable for two months, the square crystal grows to be as large as 800
pounds. It is the used in the National Ignition Facility to process laser beams on their way to the target
chamber. Notice the part about measuring the crystal where the guy pulls out a Wal-Mart quality tape rule to
