I am so happy about the Nokero solar bulb that I can't stop thinking about it. It is a solar bulb, available as a replacement for the kerosene lamps that so much of world uses. Those kerosene lamps are expensive, difficult to maintain, a fire hazard, and hard on the environment.
Like the control of kerosene prices, I'm sure the solar lights will be controlled, and not necessarily by the most altruistic people. Even the inventor sees the light as a money-making venture, not a charitable one. But the life-improving potential of this simple design is stupendous. This is a moment when you have to love design.
