Design for ethical purposes

In 2008 the average American consumed 95,834 kilowatt hours of energy, most of which would have come from the burning of fossil fuels. But if our energy use had a more direct impact on our bodies, would we think more about what we consume?
The Blood Lamp, made by Netherlands-based designer Mike Thompson, poses just such a question.

The lamp is a single-use light bulb, filled with Luminol, a chemical used at crime scenes to reveal bloodstains.

Luminol is usually clear, but adding human blood produces a bright blue light as the liquid reacts with the oxygen-carrying pigment haemoglobin.

Mike says the single-use design, and inherent cost to the individual, means the user must "consider when light is needed the most, forcing them to rethink how wasteful they are with energy, and how precious it is."

Now this is a new concept for me, but I think its fantastic and it really got to me. (yay I think I finally found another theme for my final year project)
