Space-based solar power (SBSP) is an idea that has been alternatively promoted and ignored since its inception in 1968. A space-based solar power system is essentially a satellite comprised mainly of solar panels that beams electrical energy down to a collecting station on Earth, which then distributes that energy to the domestic power grid. The [...]

Making a Quick Buck: Counterfeiting in America

2017-11-11T06:25:13-08:00 October 11th, 2008|Issue III, Lifestyle, Security & Defense, Volume X|

Counterfeiting involves the creation of fake money, and it is the government's job to stay one step ahead of these counterfeiters. While ingenuity and skill were the main factors leading to successful counterfeiting in the past, recent improvements in digital scanners and printers have made counterfeiting much easier. In order to battle these new technologies, [...]

Night Vision Goggles: Moving from Military to Modern Day Applications

2017-11-11T06:16:28-08:00 July 10th, 2008|Issue II, Lifestyle, Security & Defense, Volume X|

Night vision devices (NVDs) have allowed humans to easily blend into and exploit an environment that was once only conquered through the use of flashlights and flood lamps. Whether in goggle or binocular form, these devices have given people a significant edge, first in military combat and more recently in surveillance, security, and rescue operations. [...]

The Trebuchet

2017-11-11T03:08:48-08:00 September 5th, 2005|History & Society, Issue II, Mechanical Engineering, Security & Defense, Volume IX|

The medieval battlefield was dominated by large artillery weapons, and among these the trebuchet was king. This massive weapon was eventually capable of throwing massive boulders over 250 meters, but it did not start that way. It took over 1000 years of innovation, experimentation, and modification to transform a moderately effective projectile-throwing machine into an [...]
