This news story, Power from blood could lead to 'human batteries', has been cycled, recycled, spun and dried on news sites and blogs for the past couple of days, partly because the writer was smart: He inserted a "Matrix" reference. Between the overused "Fantastic Voyage" references and the cottage industry that revolves around making "Star Trek" technology a reality, it appears that many writers are convinced that the only way to make science breakthroughs understandable to average readers is to compare the resulting technologies to their counterparts in popular mythology. I'm admittedly geekier than the average bear, but the thought of nanobio generators being used to power implanted devices like pacemakers is cool enough to hold my interest - without the writer prodding me with the image of Keanu Reeves as a AAA battery attached to a worldwide screen saver encrypted to enslave humanity. The full commentary can be found on Howard Lovy's NanoBot.
