In Pictures: 15 amazing tech feats and world records

Not to be outdone by athletes at this summer’s Olympic games, techies have been setting some world records of their own of late.

The United States Navy knows how to destroy stuff. Case in point: In 2010 it created the world’s most powerful electromagnetic rail-gun, or at least the most powerful that the government has made public. It has firepower of 33 megajoules of force, which is enough to propel projectiles over long distances at between 4,500 to 5,600 miles per hour. To put that in perspective, a megajoule is equivalent to a one ton vehicle travelling at 100 miles per hour. The Navy may be looking to advance the technology too. It put out a request for information to investigate the possibility to building such a weapon that would shoot hundreds of rounds per minute, instead of a single shot.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

Anthony Grifoni


For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

Andrew Mitsi


The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
