Kim Dotcom: The Man Behind Megaupload

“Who is still trusting any U.S. tech company? More and more companies that are doing internet business are not going to locate in the U.S. any more. The NSA has triggered the biggest destructive event for the U.S. tech industry.” – Kim Dotcom

from VICE:

In October 2013, VICE News was invited to visit the infamous tech mogul and creator of Megaupload, Kim Dotcom, at his palatial property in New Zealand. Even though Kim is under house arrest—since he’s at the center of history’s largest copyright case—he’s still able to visit a recording studio in Auckland. So check out this brand new documentary we made at Kim’s mega-mansion and in the studio where our host, Tim Pool, got to lay down some backup vocals for Kim’s upcoming EDM album while talking about online surveillance, file-sharing, and Kim’s controversial case.

Acoustic Levitation: The Uplifting Power of Sound

Japanese scientists have released footage of acoustic levitation experiments that demonstrate the uplifting power of sound.

In this video, Yoichi Ochiai, Jun Rekimoto, and Takayuki Hoshi demonstrate acoustic levitation, which utilizes the properties of sound to cause solids, liquids and heavy gases to float.

As shown in the video, four phased arrays make an ultrasonic focal point, which is generated at an arbitrary position.

The standing waves provide suspending force under gravity.  The potential energy distribution is generated by the standing waves.

In the first demonstration using dry ice, the standing waves provide suspending force under gravity.

Particles are trapped in nodes of the standing waves in a horizontal setup, then trapped in nodes of the standing waves.  The particles are three-dimensionally manipulated in mid-air.

A variety of levitated objects are also shown, including various pieces of electrical material, wood, a screw, a nut, plastic, and soap droplets. The video notes that the workspace is touchable and open air.
