We're About 100 Years Away From a Real RoboCop

Sure, there are some morally and ethically questionable aspects of an unstoppable privatized security bot, but the armor and cyborgian capabilities are pretty freaking awesome. Why? Turns out we just don't have the battery power to operate a suit with that many moving parts for any length of time. Most iPhones barely last a full day on a charge, and a Tesla Model S can only make it about 300 miles before it needs to be plugged in--and that battery weighs more than 1,300 pounds (and is likely incapable of keep a human's organs running while being shot at). "That's one serious limitation that our technology is not approaching yet," says Charles Higgins, an electrical engineer and professor of neuroscience at the University of Arizona. "In order to do a real RoboCop like you see in the movie, you need to have a very compact power source that's going to power all those motors all day--it doesn't look like RoboCop has to plug in every hour."
