The ‘Bat Signal’ of the Future: Free-floating Laser Images Could be Fired into the Sky to Alert People to Disasters

From the article:

A free-floating image created by firing lasers into thin air was today unveiled in Japan, offering the possibility if one day of projecting messages into a cloudless sky.

Like the bat signal, its inventors hope that it might someday be used to warn people of danger, such as an approaching tsunami.

A very interesting point:

The system, as well as having possible value for advertisers, could be used to send alerts and evacuation advisories during major natural disasters because they can be seen day and night and do not require screens
