One thing that few people think about: until somebody can build an electric motor that is 100% efficient there will be a "cost" for running an electric motor. That cost is the inefficiency of the motor, which manifests itself as heat! So, in the end electric motors actually cause global warming!

If we want to cut emissions, save resources and "save the planet" what the heck would any of us be doing in an RV.
Stop and think about it.

Reisender,
I believe they also may contain cobalt, which is a Hazardous Substance.

I believe that disposing of the old batteries can be a huge environmental headache.
I can also see the value of this RV decreasing quickly with time and that it may be difficult to unload once it gets close to battery replacement time. The cost for the new batteries and for disposal of the old batteries MAY exceed the total value of the coach.

I can't get on the electric vehicle bandwagon. In the little research I've done they aren't really as eco friendly as they would have you think. To manufacture - especially the batteries - the waste and materials used to make them are pretty caustic and not eco friendly at all. And electricity still has to be produced to charge the car. You've only shifted where the pollution and emissions comes from.

The argument against EV cars isn't about whether it's crazy or that it won't catch on, it's about the claim that they are better for the environment. Despite claiming to be Eco friendly with less emissions and leveraging that for marketing, the fact is they aren't really as Eco friendly as they would have you believe.

I love the self driving aspect. How lovely to start out at night, sleep, and wake up at the destination the next morning.
