The bottled light is touted as an energy saving device that lights up homes of people for free because it uses deflected sunlight.
Many believe that this is a great and important idea. For me though, I don't find it significant or impressive at all. It is just slightly above the level of a solar powered flashlight that can be used only when the sun is out. But what for?
The poor are supposed to be the main beneficiary of this cheap -literally and figuratively- invention. However the solar bottles are not really entirely free as there are material costs in order to make them.
There are inventions that help people fight poverty. This one only makes people adjust to their poverty. That is one reason I don't like them.
