| #10 ^ Solar Impulse No beef with competition and innovation. BIG beef with current mania for filling every urban parking area and suburban cul-de-sac with filthy, inefficient, expensive subsidized people-anchors. |

| #9 Couldn't you combine batteries with solar. Once you get high enough there are no cloud problems and your upper surfaces could potentially generate power to recharge, assuming they are light and sturdy enough of course. |

| #8 As Stephen den Beste put it: "Batteries need to be better than the energy density of a diesel engine and its fuel tank, also refuel up as fast" (or words to that effect). They have a long way to go to meet that goal. |

| #7 I'll say one thing, if it catches fire, it's toast. Fuel based planes are too, but they can at least be put out. If that crashes, it's going to burn out for a long time. |

| #6 Agree with Abu. Innovation takes time. Batteries need to get significantly better and cheaper to make electric planes worthwhile. Good to see demonstrations of new tech. |

| #5 The Wright brothers didn't fly very far at Kitty Hawk either but they knew they were onto something and they kept working on it. I believe that competition and demand will drive innovation and advances in this technology until it gets to the point where it is no longer the butt of your jokes. |

| #4 You need a really long extension cord! Don't be silly. Put wind generators on the front. |

| #3 ^ Don't be silly. It runs on batteries... recharged by battery-powered generators. |
