I am not too excited about some of the seeming pushes for all electric - even though there might be some practical uses for such, and it seems that battery technology is not at such a state that commercial airlines would be able to fly if there were to be some kind of an all electric design for such, so there are some problematic aspects around some all electric applications, though it may have some reeasonable applications.. but yeah there are likely also problems with all electric in real hot or real cold climates (seasons), too...
