This sounds cool that a bloody night would make your dark night a bright night. It may sounds ridiculous but it's true for Mike Thompson, an English Designer based in The Netherlands, invented this lamp that runs by a human blood.
I can't really imagine that if you like to light up your night, then you really have to cut yourself to bleed and make your blood acts like a night lamp. Would you reluctantly think of cutting yourself to bleed just for a light? That's really a big wow for me.
Thompson came up with this gruesome idea when he was studying his masters in Design Academy Eindhoven in Netherlands. He came to research with chemicals and found his way to luminol. This is the chemical used by forensic scientist to check traces of blood at the crime scene.
On the picture, Thompson made a special glass to act like a light bulb. To use it, you have to mix first the activating powder and break the upper portion of the glass to cut yourself to bleed. upon bleeding, you have to drip your blood into the opening. I don't know how long it can be used but don't waste it because it can be used only once.
Maybe, Mike Thompson just want to emphasize that energy consumption is not just taken for granted. For every consumption we make, there is an energy being consumed that we might not retrieve back for it is limited. It's all about energy conservation. Who would think that he will use up all his blood just to waste energy for something that just not worth something. So, when it is not needed, better to conserve energy. Very nice analogy from Mike Thompson.
