this "carnivorous lamp," which appears to be designed to catch flies, feed on them and use energy generated through that to power LEDs.
Flies and moths are naturally attracted to light. This lamp shade has holes based on the form of the pitcher plant enabling access for the insects but no escape. Eventually they expire and fall into the microbial fuel cell underneath. This generates the electricity to power a series of LEDs located at the bottom of the shade. These are activated when the house lights are turned off.
And if you delight in powering your lifestyle from the incarnation of pests, check out these carnivorous gizmos on Material Beliefs' website - one being a mousetrap coffee table "that lives off the dead." Yeah... just what you want in an artsy coffee shop.
Burn, baby, burn.
