London: An American designer has come up with an eerie lamp which is powered by human blood.
The bulb exudes a strange blue glow and has been designed by a U.S. designer Mike Thompson.
To set the bulb aglow one is supposed to break the top off, use the jagged glass to cut yourself and pour your blood in where it reacts with the chemicals inside, the Daily Mail reported.
According to the designer as the bulb is meant for just one tome use, its basically an attempt to `make us think twice` about our disposable society.
Thompson claimed that the average American uses 3383kwh of energy per year, which is the same as leaving the light on in four rooms for 12 months.
Thompson claimed that the bulb is an attempt to make people ask `What if power came at a cost to the individual.`
He insisted that just as losing too much blood can put your life in danger, using too much energy can put the environment at risk.
In a disturbing video which Thompson has created, shows a woman in a dark room pushing her finger into the sharp edge and blood pouring into the lamp and the bulb starts to glow bright blue.
The bulb is powered by chemicals in the tablet, which release energy when mixed with blood.
"For the lamp to work one breaks the top off, dissolves the powder, and uses their own blood to power a simple light," Thompson wrote on his website.
"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," he said.
"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," added Thompson.
