This method is awesome, but the biggest problem isn't batteries, or whatnot. It's that the electrodes don't always last as long as we want. Often it's on the order of 6 months to a year in humans. No one wants to have their head cut open repeatedly. If a doctor said "you can walk for 1 year only" would you take it? I would, but not for the personal benefit. The loss of walking so soon after gaining it would be hard. I'd really only be doing it for the scientific advancement. I've worked in labs that do similar things, I'm not trying to knock it, I'm just saying there are still a lot of hurdles to be overcome to make it a realistic solution. And we've been working on these hurdles (electrodes lasting longer) for 10 years.
