The important part is really that his idea doesn't use electricity and recycles widely available waste to provide the lighting. It also provides more light than a window the same size would, so I imagine it doesn't create as large of a structural problem.
I worked with a non-profit called Long Way Home a few years ago who I believe was doing this, along with using plastic bottles and used tires for to build a structurally sound, environmentally friendly school in Guatemala. Unfortunately I couldn't find a picture of the plastic bottle lights in use but if you're interested, check out their website - they could use the exposure.
