Though we think of technology as a complicated discipline, the most prestigious gadgets are often quite simple. The GravityLight is just that – simple, yet beautiful. Instead of needing power outlets, solar cells, or turbines to generate light energy, it is powered by one of the universe’s most abundant forces: gravity. The system comes with a 26 pound weight, which is used to generate up to 15 Lumens of light. When the weight is dropped, its descent completely powers the GravityLight for up to 20 minutes. This concept solves real world issues, and “Each purchase provides support for the Gravity Light foundation to offer a clean, safe and affordable alternative to dangerous, polluting and expensive kerosene lamps, used by over 1.1 billion people” (Gravity Light Foundation). Because of its affordability and sustainable use of energy, the Gravitylight is used to provide light in the more rural areas of the world.
