Just too much hype and inconsistancy for me.



Has anyone done an analysis on the amount of energy required to
produce a vehicle like this vs what it will actually "save" during
its supposed lifetime? Some of these exotic battery materials and
manufacturing techiques take a lot of energy on the front end to
produce, and dispose of and/or recycle on the back end. You have
to factor that into the net energy gain or loss of actual use of
these vehicles.
