Gravia is an LED-lit floorlamp energized by people. To light Gravia, the user places a mass approximately 48" above the ground, that, in falling, powers a mechanism, generating electricity. Gravia harnesses the potential energy imparted by the user, rather than relying on any existing electrical infrastructure.
The design goal of Gravia is to provide light in a room (600-800 lumensâ€”roughly equal to one 40 watt incandescent lightbulb), over a period of 4 hours, using people to generate power.
The precedent for this lamp lies within horologyâ€”the science of keeping time. Gravia recalls the archetypes of 'grandfather clock', 'hourglass' and 'wind-up clock'. User input provides the potential energy for these devices, and maintains a cycle of timely upkeep for the life of the object.
Gravia is also metaphor for an understanding of social activism. The mechanism of social activism is like a flywheel, where each participant in society is not necessarily required to provide all of the energy to power a movement, but instead, contributes with others, bits at a time to accomplish positive change
