Comments on: The hot fuel scam costs motorists big bucks

Gas expands, so when you buy it in summer you get a lot of hot air.

Easy fix at the pump

An easy fix for this problem would be available if there was any desire on the part of oil distributors to do so. The coomputers in modern "pay at the pump" systems could easily take a temp reading and adjust either the cost per gallon to match the 60 degree standard, or change the calculation of the gallons so you might get 10.5 gallons of 100 degree gas versus 10 of 60 degree. The thing is there is no desire by oil distributors to fix the problem, because it makes them more money. And before we poiint fingers at OPEC ripping us off for oil, we need to recognize that these oil distributors are American companies.

Why Not just run on Aquygen

A company called Hydrogen Technology Applications Inc. based out of Clearwater Fl. have found a way to turn water into direct fuel. And they are not the only ones. I just wanted to know what you think. Take a look.

Not sure why this is a big deal...

It basically just means that gas is a little more expensive than we thought,
and that there's some variability to the price. Of course, most gas tanks are
underground, which greatly stabilizes the average temperature of the gas
when it's pumped; you don't seem to have considered that. But even apart
from this point, the only thing that would happen if gas prices were adjusted
according to the temperature of the gas is that gas prices would go up or
down according to the location. Certainly the gas companies aren't just going
to say "oh! I guess we ought to be making less money!"

As for the other commenter's reference to using water as a fuel, this is a
scam. Consider: start with a tank of water. Process the water into hydrogen
and oxygen any way you like. Then burn the hydrogen and oxygen to make
water, which you put back into the tank. If the conversion process consumes
less energy than the burning does, you have a perpetual motion machine.
This is a scam. This is a scam. This is a scam. What I tell you three times is
true.

Have you seen or tried a car with HHO generator? NO! Do you have a vested interest in oil/gas profits? Maybe. I use it, it works.

The Conservation of Energy and the First Law of Thermodynamics Can?t be Ignored.

The Iceland produces hydrogen from hydrothermal energy. The cost of production is cheap because is only a combination of Capital investment and Plant Operation Cost and FREE (geothermal energy).
To produce Hydrogen we have to spend a lot of Energy.
http://hyperphysics.phy-astr.gsu.edu/Hbase/thermo/electrol.html
By providing energy from a battery, water (H2O) can be dissociated into the diatomic molecules of hydrogen (H2) and oxygen (O2).
H2O => (H2) + ½ (O2) -285.83 kJ @ temperature 298K (Eo = 1.229 V)
The efficiency of water electrolysis is not 100%.
This event will occur on any conductive surface. When the proper amount of energy is applied, however, certain materials such as high surface area metals are more efficient and consume less energy to produce a given amount of hydrogen. The precious metal platinum has shown great activity for water electrolysis, attaining over 50% efficiency. Using electrodes composed of QSI nanometals, QSI has achieved up to 80% efficiency at lower current flow rates (100 mA/cm2) and approximately 60% efficiency at higher rates (1000 mA/cm2). The feed water of the electrolyzer must be distilled or deionized water, which is not cheap too.
Using ready to go technology with 80% efficiency and the electrode current density of (100mA/cm2), the water electrolyzer is not very compact and efficient, and the electrodes don?t last forever.
Installed in a car, the energy sourced from the battery has to be replaced by alternator, which in return used car engine energy with an efficiency of 25% to 30% of the burned gasoline. Producing free electricity from the Regenerative Braking System, or from Thermocouple Electrical Power Generator using the heat of exhaust system, is a different but not a simple story.
