What if, every time you wanted to switch on a light, you had to bleed? Would you think twice before illuminating the room, and in turn, using up energy?
That’s the idea behind the blood lamp, invented by Mike Thompson, an English designer based in The Netherlands. The lamp contains luminol – the same chemical forensic scientists use to check for traces of blood at a crime scene. Luminol reacts with the iron in red blood cells and creates a bright blue glow.
To use the lamp, you first need to mix in an activating powder. Then, you break the glass, cut yourself, and drip blood into the opening. The lamp is powered by chemicals in the tablet, which release energy when mixed with blood.
Mr. Thompson writes: “By creating a lamp that can only be used once, 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. The simple flick of a switch allows us to power appliances and gadgets 24/7 without a thought to where it comes from and the cost to the environment.’
