Many of us have plug-in external batteries of one sort to recharge our smart phones when we're away from power outlets. Or we have gigantic aftermarket batteries that make our phones so fat they barely fit in our pockets. So there is this company, Lilliputian Power Systems, that is just starting to market a tiny, butane-powered fuel cell they call the Nectar that plugs into your cell phone (or whatever) through a USB port and supposedly charges it for up to two weeks. That's a lot better than an add-on battery. It looks expensive, although the power "pods" aren't too pricey at $19.99 for two. But wait a minute: Why aren't fuel cells, not internal combustion engines, the "range extenders" in plug-in hybrid cars? A decade back, fuel cells were going to revolutionize our power delivery and consumption systems. A cell phone charger is cute, but is that really all we can get fuel cells to do?

Republican staffer Derek Khanna was thrust into the spotlight in December for being fired after submitting a controversial brief titled: Three Myths about Copyright Law and Where to Start to Fix it. In the brief Khanna said: "Current copyright law does not merely distort some markets – rather it destroys entire markets," a view not very popular with Republicans in the House of Representatives. Since the firing, Khanna has continued to speak out on the need for copyright reform and most recently on the law against unlocking cellphones. Derek has graciously agreed to take some time to answer your questions about copyright reform and IP law. As usual, ask as many questions as you'd like, but please, one question per post.
