Sorry, to get back so late, I had kids school activities to deal with, and
they come first.

That is highly dependant on what your doing with the vehicle, and if you
could afford the insurance premium on a second vehicle - especially a new
one.
Unlicensed golf carts are a enigma - they can run in the bicycle lanes in
many states - in others they are not allowed on the road with real vehicles
as they don't meet even the most basic D.O.T. requirements or in bicycle
lanes because they are motorized. Another problem is that they tend to
take up the entire bicycle lane and can be harder to see than folks on
bicycles - yet the folks driving them tend to treat them like cars, which
they are not.

And when you add in the cost of maitance and purchase price? That is the
killer as far as many people are concerned.

I have to disagree, the original liquid fuel of choice for personal vehicals
was alcohal, not fossil fuels. I can't find the web site right now, but
basicaly it showed how personial transportation was weaned off of ethanol
because gasoline was ( at the time ) a waste product of refigning kerosene
from oil.
As such, had we stayed with alcohal, wea would be much further along in
cellulose to ethanol - but again I disagree that ethanol is the answer -
butanol is about on par with gasoline as far as BTU's are concerned and it
can be produced for lower cost from a wider aray of materials than ethanol
can.

That is true if one only considers the ethanol as the only end product, and
again it's also dependant on the particular method used.
As far as Iogen is concerned, did you take into account the eletricicy
generation ( that increases the efficency ), as well as other side products
( for paper, textile, and animal feed industry ), that increase efficenies
in their respective industries?
What about the fact that not everyone knows how to run a gasifier at optimum
efficency, and that gasifiers on vehicals rarely run at optimum efficency
due to the effects of things like pot holes?
Don't get me wrong, gasifiers have their place, but as far a vehical power
is concerned, it's not one of them, just for the simple mater that not
everyone has the talent to run one.
Do I need to remind you, that one particular group, is basing it's cellulose
to ethanol production on the use of a gasifier to run the process?

Is it, ready to go? Not everyone has a gasifier, not everyone knows how
to build one, not everyone knows how to run one. Fewer people know about
gasification, than ethanol - for that matter, if for no other reason than
the fact that it's still easier to pump a liquid into the fuel tank of a
vehicle and drive away, gasification for mobile applications will always
play second fiddle to other technologies - and because of that it will play
second fiddle to other stationary forms of power as well.
