EV range is interesting as so many new factors. While long range is
nice for those that actually need 100+ miles/day, most just don't need over 120
miles I see as a sweet spot for most. For many just a 60 mile range EV
can work as many in Fla seniors only use Golfcarts and NEV's now as their only
transport. And for the few times more is needed a RE using cleaner fuels
or Alum/Zinc-air primary batteries are already proven to give 1,000 mile range
just EV builders refuse to put in the brackets, plug or space for them like a
trailer hitch mount. We really need to get these alum/Zinc air RE
available as already proven, just need a market to sell them. Between EV's and
home, building markets if available would be a killer app. As fairly
light 50lb modules could be sold near anywhere including gas stations just
exchanging the spent one with a reformed one. This is complicated as EV
batteries shrink in weight, space both which have been improved 30% in the last
few yrs and likely to double range/lb of battery in 3-5 yrs. Next
building eff EV's gliders by cutting weight by 50% with better aero can cut
battery weight, cost/100 miles by 50% even with present EV lithium batteries.
The GM Ultralite, Toyota 1/x, Solectria Sunrise, Visio.M, and other
composite body/chassis show the way. Sadly the i3 weighs more than a
same size steel car from really bad design using an alum frame instead of just
bolting everything to the CF body. Since it has to pass crash tests the body
has to be strong enough to carry the other loads anyway. So half the
weight, drag EV's using half the weight EV batteries with 2x's the capacity
even 200 mile range would be low cost, practical. And in 5 yrs likely
to be in production as by then oil will likely be $5/gal but EV's need cost no
more than a gas car because of these but only 20% to run.
