From NPR's Talk of the Nation Science Fridays:

Quote:As part of a research initiative on how to harness off-grid energy for low-power electronics, a pair of U.K.-based designers created a lamp that uses gravity to generate light. Martin Riddiford, co-inventor of the GravityLight, talks about plans for the innovative project.

It's relatively cheap, works as a generator (no battery), and you are able to attach other devices peripherally. As LED and electric tech advances, this type of generator becomes more useful. Potentially very useful for developing nations.
