The Matrix using our bodies not to far in the future?

"Ecobot Eats Dead Flies for Fuel"
Wired News (12/15/04); Sandhana, Lakshmi

"The Ecobot II robot developed by University of the West of England professors Chris Melhuish and John Greenman uses microbial fuel cells (MFCs) to convert organic matter--specifically, dead flies and rotten apples--into electricity. Machines such as Ecobot II are an early step toward the ultimate goal of a self-sustaining, self-powering robot that can function for years without human assistance. The MFCs comprising the Ecobot's "guts" contain microbes normally found in sewage that break down raw food into sugars, and the cells take in oxygen from the air to generate useful biochemical energy that is turned into electricity. Ecobot II manages a peak speed of roughly two to four centimeters every 15 minutes, an act requiring the consumption of eight flies; it currently takes about one to two weeks for the machine to extract approximately 90 percent of the energy contained in three to four flies, although the research team is working to shrink that interval down to a few days. MFC-driven robots are idle most of the time while they power up, and fuel cell performance and longevity are still easily outmatched by standard alkaline batteries. "Until today, the maximum open circuit voltage of a microbial fuel cell is not more than 0.75 volts and that goes down in current production, which is not enough to power most of the electronics, including many handheld devices," notes University of Massachusetts professor Swades K. Chaudhuri. "However, with further discovery of a novel bug that can quickly oxidize organic material or by modifying existing bugs genetically there may be a way to enhance power output." As more powerful fuel cells emerge, the Ecobot could be equipped with sensors that allow the device to detect the presence of food, or use pheromones to attract flies."

I know people are scared of matrix like concepts, well don't be afraid the Matrix is not real. ;) Now go back to your daily routine. Muhahahahaha
