The drawbacks of LPG include:

In cold conditions, below 32 degrees Fahrenheit, starting could
be a
problem because of the low vapor pressure of propane at low
temperatures.
One gallon of LPG contains less energy than a gallon of
gasoline.
The driving range of a propane vehicle is about 14 percent lower than
a
comparable gasoline-powered vehicle.
LPG is generally higher priced than other fuel alternatives such
as
CNG and gasoline.
There are over 4,000 LPG refueling sites in the US, more than
all of
the other alternative fuels combined. Most of these stations, however,
are not readily available to consumers on a 24/7 basis. This is one of
the reasons why most on-road applications are bi-fuel vehicles, which
burn LPG and gasoline.

You will notice that the Lion battery is way down near 0,0.

The Lion battery's days are numbered. Better technology is just
around
the corner.

They are working on the heat problem. They haven't come up with
anything
better, NiMh isn't any better. The plastic batteries are not ready for
prime time. And the ceramic batteries are not cost effective to
manufacture.

LPG is NOT higher priced than gasoline.

By what measure?

Cost.

Cost per gallon? Cost per pound? Engineers are supposed to be precise
and un ambiguous. So far you ain't doin so good.

Does it matter? Considering the current respective costs, cheaper is
cheaper.

At this time it is cheaper per gallon.

At this time it is cheaper per pound.

At this time it is cheaper in cost per distance covered.

At this time it is cheaper in BTU consumed.

It is cheaper to use as a fuel.
----------------------------------------
Cost per MPG? LPG is about $3+ around here.

$3 ? It costs $60 to fill a 20# grill tank? Holy crap! I can get one
filled, retail, for a little over $14.00, including tax.

I buy 33# for about the same price including tax, delivered. (This
company won't do consumer tanks.) Who knows what the stuff really
costs? And what the markup is.

Realize that $3 per gallon at 4 1/2 gallons equals $13.50

Maybe we need clarification on whether it is $3.00 per gallon or $3.00
per pound. Normally, one purchases LPG per pound, not gallon. Tanks
are size by pound, not gallon. Buying a gallon of product, without
control of density, is pretty lame.

In any case, when buying small quantities, you are paying about twice
what the product can be bought for (retail) in larger quantities.

Storage tanks are sized in cubic feet.
Propane id dispensed by the gallon from the tank.
Usually, but not always, larger packages of something are sold at lower
per unit prices than smaller packages.
Sure looks like these storage tanks are being sold size by the gallon.

Stationary propane is dispensed from the tank by molecule, metered by
the gallon, and charged by the pound. Check with your local
distributor, better yet, just watch them fill a tank. If it doesn't
have an over-pressure shutoff, they will fill the tank by weight.
Otherwise, they just pump until it won't take any more.

Since you are something of a smart fella, maybe you can provide us some
comparative data on the cost per unit of energy available from gasoline
vs propane (LPG). Leave aside the additives the greenies/Govt. stick in
the gas to lower its energy and ruin gasoline engines.

This explains the matter from a number of positions and clearly states
that "you get more bang for your buck with propane when compared with
gasoline." Maybe you will have time to review the conspiracy of using
molar chemistry.

Clear as mud.
