Anna Stork and Andrea Sreshta were two graduate students who wanted to make a difference in the world.

When the Haiti Earthquake hit seven years ago, they realized that while food, water and clothes donations were being made, they saw...or didn't see, that something else was missing.

Light.

Together the two women have built a company LuminAID; an inflatable, solar powered light that can provide more than 30 hours of light.
