The Busy Skies

On America’s busiest travel day, it’s worth pulling back — or up — to marvel at how the globe has been so thoroughly knitted by aviation. About 2 million Americans are in the air on a typical day. In 2009, 4.796 billion passengers traveled through the world’s airports. A dizzying variety of products flows through the skies worldwide (the impact on commerce from the eruption of one volcano in Iceland illustrated this). And of course less welcome things move this way, as well. It’s very likely that a jet carried West Nile virus to North America in 1999.

I would look over and there would be mom. The glassy eyed look, the stare into what must be either confusion or "nowhere". The look of Alzheimer's and dementia.

Advances in Holographic Technology Could Have Far-Reaching Implications

But now another major development in holographic technology is making headlines. A new device has been created that can transmit 3-dimensional images in close to real time. This could result in major advances in holographic tele-presence technologies. For example, I could conduct a keynote speech in Tokyo from the comfort of my own home—a 3D, high-resolution, full size image of my body could be projected on stage in front of a live audience over 6,000 miles away.
