Hm, not sure... but I think if it was linked up to our sweat-glands, tears and "inner water balloon".. along with appropriate filters, we'd probably be able to keep it going more or less indefinitely... that is, until the lightbulb runs out, or the plant and wait.. WHAT'S POWERING THE LIGHTBULB? Oh i got it - a generator attached to the leg movement somehow.* Or jaw if you like to talk.* or blinking - YES!* recharge the light by blinking. Hm. this is sounding more and more frightening by the moment :P Add a comment...
