The idea behind “Smart Dust” is that tiny robotic particles will be deployed into the environment equipped with computer power, sensing equipment, wireless radios, and a long battery life.  Hewlett-Packard has announced it is working on a “Central Nervous System For The Earth” project where the company will deploy trillions of sensors all over the planet.  The hope is that these sensors will be able to relay data concerning different parts of the Earth in real time, thus providing better information on situations or potential situations to prevent accidents and loss of life.
