While sticking a 110hp electric motor into a car might have some appeal, I am FAR more interested in putting it in a small plane. A Rotax 912 is roughly the same horsepower and a few pounds heavier. Using this electric motor as a replacement for that for short joyrides around the patch has real potential in the experimental / homebuilt crowd.
With the standard caveats of batteries and weight issues.
The energy density of batteries isn't close to good enough. Small personal aircraft have a _very_ narrow weight allowance - and do remember the FAA mandates a minimum of 30 minutes of reserve fuel.
