Green? Because it runs off batteries? Is that all it takes. OK, but didn't we just have a discussion on hacker news showing that helicopters with one large blade are more efficient than ones with many smaller blades?

It's easy to ignore where your power's coming from when your vehicle's not burning fuel-- in the US, ~40% from coal and ~30% natural gas. Morality fades away when the results occur at a distance. Compare plugging into a socket to pumping gas, or buying cuts of meat to slaughtering an animal.

  Right now gasoline-powered vehicles are a problem along with burning coal and natural gas. At least by replacing gasoline-powered vehicles with electric we solve one issue and focus can be directed to how we generate that electricity.

  Centralizing power production, even in a coal-burning plant, is better for the environment than burning fuel locally (and extremely inefficiently) in a helicopter.

    So just ignore the "emission- free" quote on their home page.

      The helicopter is emission-free. How you power it is up to you. You have the option of using an emission-free source, which is not an option with normal helicopters.
