There are 1.3 billion people today who have no access to electricity. Many of them rely on kerosene lanterns for light, but kerosene is both expensive and hazardous to the health.

I don't think you need to be so result-oriented when you're trying to define the success of an art work. I think we can allow some unpredictability.
