I came across an interesting article regarding the possibility of running an engine on nothing but HHO, aka hydroxy. There was much more to the article but I wanted to share the part of the discussion regarding the possibility of running an ICE on no fossil fuel. Granted, we aren't "there" just yet but it isn't outside of the realm of possibility. The aim of the article wasn't to say that the author is doing this but to provide information which strongly suggests that it could be done:
How much hydroxy gas is needed to run my car engine alone?
One common mistake many people make is the incorrect assumption that
production. This is not the case - not by a long shot. Many people
want to claim you cannot add any air to the hydroxy mix - but they are
wrong! The hydroxy is metered into the engine and mixed with air
similar to the way propane or natural gas is. Another common mistake
is failing to convert the liquid volume of water into a vapor volume.
Remember, the water is split first and resulting gases are what
combust. The third mistake is people using hydrogen properties
instead of hydroxy properties to perform their calculations.
For example: Hydrogen - oxygen mix in its monotomic forms has more
energy in it than a similar volume of propane. A typical propane
company work vehicle consumes .3 liquid liters per Km of propane, at
an expansion rate of 270:1 thats 81 L/Km gaseous propane. Traveling
at a very normal speed of 100 Km/hr, that's a consumption rate of 135
LPM gaseous propane.

stories/cars-minivans-london.cfm?attr=16
Propane gas has an energy density of 2.3K
gas has an energy density of 270
same vehicle would need 8.5 times the propane fuel rate, or 1147.5 LPM
H2 gas. Remember this number you will see it come up again in close
proximity later in this post.

There are plenty of hydrogen powered ICE cars out there. Here is a
hydrogen powered Cobra built to break a land speed record.
http://www.clean-air.org/Hydrogen%20Cobra%20Story/Hydrogen%20Cobra.htm
Note the tank on this car holds 590 standard cubic feet of H2, and it
empties in 5 min while doing a run. Thats 118cfm, or 3342 LPM. This
would seem to support some of those outrageous claims. But this is
not your typical engine. First of all, that is what was consumed at
WOT during a land speed attempt. Secondly, its a huge bored and
stroked 527CI. There is no air metering (no throttle plates, engine
speed determines airflow, not throttle position) and they engineered
the engine to run at a crazy fuel ratio of 80:1 in order to eliminate
the Nox emissions we have been talking about. Not many of us are
going to try and build our engines like this. Most of us will be
using air metering devices, running an A/F closer to 34:1, and closer
to the 350CI range or smaller. My Olds motor is less than 1/2 the
size of this beast, so if I wanted to set it up with this
configuration (which I wouldn't) I would be using around 1400 LPM H2
gas. Put some throttle plates on it and drive it normally and I'd be
closer to 1000 LPM. There is that number range again.... On that
note - look at this next H2 car:
The BMW hydrogen car uses 17.6 lbs, or 17.6 lbs/(4.432 lbs/ft3) =
3.97 ft3 = 112L of liquid H2 to go over 125 miles (201.2Km)= .56L/Km.

bmw-hydrogen-7/
Hydrogen has an expansion rate of 1:848 which means the car uses
472L/Km H2 gas. Assume a nice speed of 100KPH, and you get a fuel
demand of 787 LPM. Somewhere in the ballpark of what I predicted for
the Olds and calculated for the propane rig above...
Now take into account that hydroxy is NOT H2. Here is where we all
need to sit up straight in our chairs:
One researcher calculated via experimental data hydroxy gas contains
60,000 KJ/m3 of energy at 1 atm. Now there have been varied reports
up to ten times this value - but this is the lowest one I could find
so I chose it for the worst case scenario. Keep in mind our ongoing
discussions about the mysterious "soup" some of our cells generate.
http://www.phact.org/e/bgas.htm
Compare this to hydrogen gas which contains 10,000 KJ/m3 at 1 atm.
Thats 1/6th the energy of hydroxy! With that observation, let us
substitute hydroxy into the previous calculations:
The propane powered rig would need 190 LPM hydroxy gas.
The Cobra would need 560 LPM hydroxy gas.
My Olds would need 170 LPM hydroxy gas based on the comparison to the
Cobra.
The BMW would need 130 LPM hydroxy gas.
Let's talk about the Olds some more. My Olds gets about 23 MPG at 60
31,150,000
would mean that almost 4 times the amount of liquid hydrogen would be
needed, or .66 LPM. With an expansion ratio 848, thats 560 LPM
gaseous H2. Now, I calculated that hydroxy has at least 6 times the
energy of H2, so the projected demand for my Olds is 93 LPM based on
my observed gasoline mileage and the conservative reported
hydroxy. Notice how this calculation supports my previous statement
concerning the comparison with that bad ass Cobra. Even that beast
could be designed to run on less fuel. Frank Roberts has made a claim
of 20 - 30 LPM with his Taurus which is not that far from my own Olds
estimate and certainly no where near to being close to 3000 LPM.
Perhaps with the proper tuning, correct hydroxy mix and good driving
habits I could get into the 30 LPM range like Frank did, an order of 2
magnitudes less than other's estimates.
That brings the technology right back into the realm of possible!
