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 Thomspon, 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 scence. 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.
And this, my friends, is how our robotic overlords will read their Kindles at night. And I'll be damned if I become some robot's lamp juice. You hear me?! You will never take my blood! Quick, Edward, bite me! DO IT NOW, NANCY! *swoon* God I love your hair.
