This is a terrific product that can be used in the 3rd world, but also camping, and in emergencies. I’d love to use it to read in bed!
THE PORTABLE LIGHT PROJECT
Portable Light is an interdisciplinary research, design and engineering project to create and implement new models for energy efficient electrical power and lighting. Portable Light applies creative processes and strategic integrative thinking to optimize existing semi-conductor technologies and create new applications to serve the large number of people—more than 2 billion—who do not have access to electric light or power. Portable Light is based upon the principle that global needs for technology development are inevitably interconnected. Knowledge, techniques, market solutions and data produced by the project benefit the “third” world and the “first” world where the need to imagine, design and develop energy efficient alternatives to the centralized and increasingly costly electrical grid is becoming ever more important.
The remarkable energy efficiency of high brightness solid state lighting (HBLEDs) means that a bright digital light of 80 lumens per watt (bright enough to read, work and illuminate areas at night) can be produced by a single miniature diode and powered by small areas of flexible photo-voltaic (solar panels). Portable Light expands the value of miniature solid state electronics by putting digital light into a textile medium to create cost effective, completely portable, off-the-grid light engines that can be deployed at a global scale wherever energy efficient electrical power and illumination are needed.
