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)
