Hey, read my intro post... it's OUR thread.
I can't seem to get the video to play (not unusual, this laptop is struggling with an advanced rash of overuse
), so until I do, I will assume
it to be true. I do believe there are ways to do this.
Now, if this farmer has developed a way to split water, then he is making hydrogen and oxygen,
along with some other chemicals from impurities
found in all the water on the planet. That is an important point as far as the pollution-free claim is concerned, since the pollution form
petroleum fuels comes from the same phenomena. It is rare to find anything in nature in a pure form, or even to be able to produce something in a
totally pure form.
There will be salts of sulfur, halogens, nitrates, and trace amounts of various metal salts produced as these minor impurities are themselves broken
down by the process. This will produce acids during combustion, which will eat away, slowly but surely, at the engine components over the years,
leading to a decrease in engine life.
There is also the problem of using hydrogen as a fuel. Let's assume that we can use water as the energy carrier. That means that the fuel tanks use
water, which will lead to rusting and decomposition of the metal firstly. this means that water tanks will have to be either glass-lined (easily
broke, heavy, and expensive) or plastic/plastic-lined. Plastics still come from oil, so while we may have decreased our reliance to a huge degree, we
have not created another use for oil.
Now the hydrogen has to be produced to be burned in the engine. Hydrogen is explosive under most conditions, which means that an accident (and trust
you me, there are plenty of these) could turn from a fender-bender into a fireball express if there is more than a minute amount of H2 available.
Hydrogen also has another problem with this, and that is the fact that it burns clear. It is completely possible to have a hydrogen fireball that is
invisible to the naked eye. the reason you can see most hydrogen explosions is that the materials around the hydrogen are burning as well, and these
materials alone give off a colored, visible flame. So if there was a fire from the hydrogen, it might be difficult to even realize the car were afire
until you were afire as well. Not a pretty thought.
But let's say we have plastic tanks and are producing barely the amount of H2 we need to power the car immediately. Hydrogen also burns much hotter
then gasoline. A typical engine would require a much higher capacity cooling system, and quite probably a redesigned internal arrangement to allow for
increased cooling. Also, the output of the hydrogen flame is water. Just water. What does water do to ferrous metals, even in vapour form? It
decomposes them. So again we have the problem of shortened vehicle life, just as we had with metal fuel tanks.
Now all of these conditions are correctable with some work. We can use plastic tanks, adjust the hydrogen production to minimize the amount of
hydrogen produced, and redesign the engines to allow for greater cooling abilities and non-ferrous combustion chambers. None of this even requires
'cutting-edge' technology. What it does require is money, for research and production of the cars.
Money is something a lot of people take for granted. We live in a society today where a good percentage of the population simply go to work, then buy
what they want, without major regard to price. In that context, it is easy to forget that there are plenty of people who do not have ready funds
available to them for technological upgrades. You also have a population that is habit-driven. While there are probably quite a few people who would
state that they would gladly purchase one, the sad fact is that new technology is often viewed with skepticism from the general populace. It may not
be logical, but there are plenty of potential customers who would hesitate to move away from gasoline at $20 a gallon, simply due to habit. This means
that the potential customer base for a water-powered car is pretty low initially.
That is true for any new technology, not just this one. But it indicates something every developer knows:
new technology takes a log time to become
accepted in the general populace. Lasers have been around since 1960, with the development starting as early as the late 1920s. Yet they have only
come into widespread use the late 1970s and are still finding new uses even today. And this is a technology that does not replace an older one.
Bottom line is, it will take decades for hydrogen to come into play in any major way in our economy, barring a sudden and complete removal of oil as a
possible energy source, something I do not expect to see.
Now as to geothermal, it is a wonderful idea, but it is also plagued by the same societal resistance that the hydrogen car faced in the previous
paragraphs. It is expensive, and takes much more to install than a heat pump or furnace. The heat transfer system must be located either in the ground
well below the frost line (which can be up to 6 feet deep in more northern latitudes), or in large bodies of water. The transfer field also must be
fairly large compared to the present alternatives, requiring access to land or water by the user of the geothermal energy. Not everyone has access to
this much land area, especially those in the cities, where energy usage is being pressed the most.
If someone lives in a more rural setting, geothermal is definitely the way to go, even if only in combination with other technology. As an example,
the typical heat pump (the type of climate control used most frequently around here) is efficient at temperatures above 40F. It is notoriously
inefficient (and frost-prone) below that. Geothermal systems typically provide 60F air temperatures, which would result in a major increase in
efficiency on those cold winter mornings.
So even with the advantages of geothermal, and assuming the possibility of hydrogen-from-water fuels, it will be a long time before these are a viable
alternative for the general populace. In the meantime, while we wait, is it not smart to continue the search for more oil?
