Thanks to those who replied to my inquiry. My instinct is that a real
engineer with familiarity of the cars design would be needed to pull
this off.
David Roden makes some very interesting points. He points out that the
emissions are high for less regulated motors. The pollutants that he
sites are CO, NMHC + NOx. This certainly give me pause for moving
forward. CO2 is definitely a motivator for me. The emissions for this
are gallons (10% ethanol) typical x 19#CO2/gal (epa website
http://www.eia.gov/tools/faqs/faq.cfm?id=307&t=11 ).
I have evaluated the actual gas mileage using David’s metric of m/kwh
x speed to determine kwh/h or kw of continuous power. I would need
14.3 kw generator. Using this 15 kw generator
http://www.electricgeneratordepot.com/generac-5734-gp15000e-15-000-watt-electric-start-portable-generator-992cc-ohvi
I end up with a mere 18.75 mpg not accounting for the reduced m/kwh
for the trailer. Our Honda Element (2nd car) gets 25 mpg. The trailer
would only make environmental sense if we can go back to using
renewable energy while we are at the destination. My figures are
pasted in from spreadsheet below.
Though Davids prototype gets higher m/kwh than the leaf, I still
promote the all electric car for local use. This 80 mile range
achieves 75% of our annual auto transportation needs. We added
photovoltaic array to produce as much power as this consumes. This
greatly reduces our CO2 emissions for auto transportation.

It would probably be quite difficult to convince the Leaf to use the
onboard charger while also moving. You would also need well more than
6 kW of power to move down the freeway.
You may find it easier and more efficient to build a "pusher trailer"
out of the front end of a FWD car, such that the gas engine will
"push" your leaf down the freeway, with a remote gas/brake control in
the Leaf.
(Or you could use a larger motorcycle back end as your "pusher".)
The leaf could even use regen to recharge on the freeway if the pusher
motor had enough HP.

Hi EV List
I own a Nissan Leaf. It is a great car. I get 4.2 miles/kwh of battery
and 80 mile range for 24 kwh battery. I believe this is better than
the plug in hybrid, though I do not know. This works perfect for local
trips where 80 miles is plenty and the car can be recharged slowly
overnight. However, I sure would love to drive it to visit my family
who are much beyond this range.
What if we created a trailer that would have a generator with
sufficient capacity to charge the battery while traveling distances
beyond the 80 miles. Likely, I would loose some mileage with the extra
weight. However, once at the destination, the trailer could be
detached and I can go back to being an all electric vehicle.
A simple idea that I am sure is not that simple. However, if I
purchased an off the shelf generator that could charge at level 2
Charge Rate 1.41 kW - 6.16 kW, I could use the standard plug, perhaps
relocating the female to where the front flap would not need to be
open. One problem that may be beyond my engineering skills is safely
allowing the car to charge while in motion. Currently, the car will
not start if the plug is connected. I am sure this is a feature meant
to prevent people from inadvertently driving away with the chord
plugged in. However, once I start messing with the engineered product,
I could get into trouble.
This list has a lot of smart people. Has anybody tried a similar concept?
