I remember going to a door once where this young guy, probably mid 20s, came to the door without a shirt, and he had these HUGE pecs. I mean they seemed almost out of proportion to the rest of his build, and he wasn't fat or anything. It was just like all he ever did was bench press. So, I tried not to stare at these huge pecs, mind you, and go through with the presentation. I wouldn't call it a "dirty" moment, just kinda embarrassing.

Dirty Field Service Moments
by saywhat29 inhey everybody!.
i thought it would be fun to share some of your nasty/funniest/embarrassing/messed up/dirty field service stories- witnesses get off on driving around and sharing their stories with each other since... they usually have nothing else in common with the people they are driving around in field service with- but field service itself.. and you know i'm right, driving around listening to brother and sister so-and-so tell you about their amazing study.. who will never ever step inside of a kingdum hall in their lives (smart folks i have to say).
so here's one of mine- a favorite:.

Fuel From a Garden Hose - Hydrogen Fuel
by BlackPearl inhas anyone here thought about the possibilities of getting all of our fuel needs from the unlimited supply of hydrogen in our water?
you see, there two parts hydrogen to every single part oxygen in h2o.
what that means is, if we can extract the hydrogen from the water, we can burn it as a fuel, just like propane or gasoline.

Terry-
Thanks for that information. I know my comments have seemed negative so far, but I really do admire the technological innovation that has gone into the development of fuel cell vehicles.
BP-
I admire your enthusiasm. By all means keep looking into the alternatives. You know what I wish? If the United States would focus on its public rail infrastructure, then more people could use public transportation instead of private cars. Since public transportation has to be professionally maintained, it would be an excellent way to introduce fuel cell technology. If fuel cells can power street cars in small cities and suburbs across the country, then that would be a way to introduce the basic infrastructure of a "hydrogen" economy without waiting for a critical mass of cars to be built.

Gopher, the "war on terror" started long before the Bush II administration. The video, what I saw of it, states that the Reagan administration also had a "war on terror."
Frankie, I can't watch the whole thing. It downloads too slowly for me. Plus, old Noam seems to get more rambly with age. From what I can tell, though, he isn't going anywhere he hasn't before. For anyone interested, I would highly recommend reading his books What Uncle Sam Really Wants and The New War Against Terror which can be downloaded via p2p network.
I'm not sure I understand why the US Govt's support of the killing of innocent brown people in foreign lands is a "left" or "right" issue, but the general ignorance of the white American public about what goes on around the world is sad.

Hi BP, I'm not an expert on any of this, but I will try to answer based on what I know.
1. Why can't solar power be used as the energy source at an individuals home to produce the Hydrogen and store it? Then fill the tank once a week with the collected Hydrogen.
Yes, this is possible. In my original post my only caveat was cost. A large part of this cost is due to scalability. We made hydrogen in science class in high school. That's not the problem. But, how much hydrogen does it take to drive the average 250 miles per week in a typical 2000lb. vehicle? How much electricity does it take to produce that amount? Depending on weather conditions and hours of daylight available, how many solar panels would it take to make more than enough electricity? Then you need special storage and pumping systems. Hydrogen has to be stored under great pressure. How much of your electricity will it take to achieve that pressure. All this is to say that it is expensive, and in my opinion it is not a "green" solution for transportation.
2. If we're using solar power to produce the Hydrogen, then I guess the question arises, why not just use the energy produced by the solar collector to power a vehicle in a battery and skip the Hydrogen process?
Exactly. You can use readily available materials all the way and it would be far cheaper. On top of that, you can plug in just about anywhere to get a recharge too.
3. Can the Hydrogen be collected onboard the vehicle while traveling? Could we put solar panels on the rooftop (or some sort of wind generated form of collecting energy in the grill- like the windmills that produce energy by virtue of generating energy with the wind passing by) of the vehicle to capture the electrical power needed to produce the Hydrogen, then use that DC power to extract Hydrogen when the car needs it as opposed to storing it?
To answer the first part of your question check out the solar car. As you can see from the link, these vehicles are extremely aerodynamic and lightweight because the energy from sunlight, even on a clear summer day, is still relatively diffuse. That is to say, sunlight is not concentrated energy. It is interesting to note that these solar cars use compact rechargeable batteries to save space and weight. A hydrogen conversion, storage, and combustion apparatus would add too much unnecessary weight.
Now, I'm not entirely sure if I understand what you are getting at with the second part of that question. If you are referring to land sailing, then I must admit that that sounds like a lot of fun. However, if you are referring to using the apparent wind generated by a vehicle's motion, then I must say that it cannot work as it violates the laws of thermodynamics. As you can see from the pictures of the solar cars, designers try to make vehicles as aerodynamic as possible because energy loss from wind resistance is unrecoverable.
4. Why can't we use Hydrogen as a fuel and burn it like gasoline in our engines as it's being produced onboard?
You can burn hydrogen in an ICE. I honestly don't know what kind of conversion is necessary beyond the obvious fuel system differences. I think that fuel cells are supposed to be much more efficient, giving far greater range on the same amount of hydrogen. Even at high storage pressures, hydrogen tanks take up lots of vehicle space. I think that they are specially made of carbon fiber due to the corrosive effects of hydrogen gas on metals. Can hydrogen be made from solar panels on the car? Yes, but you wouldn't have much range if you only relied on them, same as with recharging batteries using solar cells on a car.
Any "green" solution will involve a radical shift in our priorities. I think that the solar car I linked to above is a good example of that. It is small, lightweight, and aerodynamic. A Ford Expedition it is not.
Like it or not, we are products of the oil age. Oil is stable at room temperature. Oil is a very concentrated energy source. Oil can be transported easily in common metal and plastic containers. Oil is an unparalleled substance, not even equaled by natural gas and coal in it's versatility and usefulness. That is why the human race has become locked into it and utterly dependent on it. I believe technology won't save us from our addiction.

?Please explain Evolution to me in simple terms
by Guest with Questions inand please dont give me links to read.
i dont want a complicated version; just a very simple explanation on the theory of evolution, and if possible, in your own words.
many of us are very ignorant on this subject and it seems that a few here are very knowledgeable so i hope you can help me and others also.. also if you believe in the theory of common descent, could you explain that to me also?

For the original poster, an explanation that I hope will be easy to understand.
Think about what a living thing is.
All living things, humans included, are made up of cells.
Evolution, as with all of life's processes, occurs at the cellular level.
Entropy is what causes organized things like cars and buildings to break down.
These things do not evolve because they are purpose built and do not reproduce.
A cell is a set of chemicals that take in energy and export entropy (disorder).
A cell is a chemical unit of "negative entropy" (order) supported by external energy.
A cell has a boundary to help it maintain its own internal order.
A cell has the ability to copy itself.
Each copy is different from the original in some way.
Single celled life existed and evolved for 3 billion years on Earth before multicellular life evolved. (Look up Symbiogenesis.)
Simple multicellular lifeforms evolved when certain single celled lifeforms cooperated for greater efficiency.
Multicellular lifeforms use boundaries more efficiently for taking in energy and exporting entropy.
Multicellular life evolved further when cells took on specific functions and formed organs, hierarchical cellular boundaries.
An original can be destroyed and lost forever, so reproduction allowed lifeforms to preserve themselves through offspring.
As an aside, in the history of life on this planet, only the preservation of the lineage has ever mattered, never the individual.
You and I are the product of a continuous lineage of living things that have existed without interruption for billions of years.
Each of the millions of distinct species alive today is also a product of a continuous lineage existing without interruption for billions of years.
All lineages merge at some point or another until a common ancestor is reached.
Any species that no longer produces offspring becomes extinct.
Life is a process that can occur anywhere in the observable universe because all of the laws of physics and chemistry are the same everywhere in the universe as what we observe on our planet.
Life is an inherent feature of our universe.
No one knows for certain why our universe is the way it is.
There comes a point in one's search for answers where one realizes that it's not so important where we came from or how, just the fact that we are.

It`s Time to Bitch about Gas!!
by OUTLAW ini just had a big bowl of chili..but..thats not the gas i want to talk about..lol!
!..........i went to the nearest gas station which costs me $7.00 in gas to get to..i couldn`t believe how much gas had gone up since i had been there last..$1.30 per litre!
!..or..$5.20 per gallon for premium gas..outrageous!

Elsewhere- I'm going to download that. Thanks for mentioning it.
My first exposure to Peak Oil was the documentary The End of Suburbia that I watched over two years ago. Here is an interesting comment by author James Kunstler on the fast-developing permanent oil export shock. It's Peak Oil on steroids.
To our friends across the pond, please remember that 1 US gal=3.79 liters. Therefore, $1.98/liter=$7.50/ gal. I made a mistake in my conversion earlier. I paid US$ .70/liter which is US$2.65/gal. In PR we probably get our gas straight from Venezuela.

Demon Experiences
by gumby ini believe that in the past i've started threads about ghosts and such but i haven't started one about me asking others if they have had a personal experience with a demon.. a couple of days ago i was talking to my dub son-in-law about how i wish i could believe in the unseen....such as ghosts, the paranormal, or anything out of the ordinary.. he said to me......"well what about demon stories"?
he related some stories that were given at an assembly from some who were greatly bothered by demons, mostly from africa.. so, what are we to make of those with such stories?
are they lying?

I have had minor sleep disorders in the past. I would go to sleep or be on the verge of sleep, become conscious and yet unable to move my body. That can be scary, but it has to do with brain/body chemistry and not the supernatural.
I knew a couple of kids that played with a Ouija board that one of them had made up by himself. They claimed to have had a supernatural experience.
I knew a non-dub co-worker who claimed that a possessed cat attacked him when he was smoking pot with some friends.
My father, a congregation elder who has often worked the night shift in the past, claimed to hear unexplainable noises when he was at home alone during the day. Apparently, my brother was listening to some "demonic" music that was the cause of the noises. I had moved away from home by then, so I don't know what to think about that.
Again, my father said that he saw a waving hand appear over my sleeping grandmother, his MIL, while they were taking care of her in her old age. Of course, they assumed that she had something "demon possessed" in her belongings.
I have played the Silent Hill video game series and listened to the darkest, blackest metal music (Blut Aus Nord) and have yet to meet any interesting astral entities. I've got Lon Milo Duquette's book My Life With the Spirits. I've got Donald Michael Craig's Modern Magick. Heck, I've even got a dummy's guide to meditation. Still, nothing. I can only assume that Satan has me right where he wants me. Any move on his part would drive me right back to Jay Hoover! NOT!

Water is not a fuel. Hydrogen is not an energy source. It is a way to store energy made by some other means. You need energy from something, like solar cells or an electric power plant fueled by coal, natural gas or nuclear energy, to make hydrogen. Hydrogen can be made on an industrial scale from natural gas and even coal. It costs more energy to split the water molecule into hydrogen and oxygen than the energy you get from using the hydrogen in a fuel cell. No matter how efficient your process, you cannot go beyond the laws of physics.
Using hydrogen as an energy storage medium is almost the same thing as when you charge your Li-Ion, Ni-Cad, or NiMH batteries from your wall outlet. Using hydrogen is like using a battery. I say almost, because hydrogen is an extremely corrosive gas that requires careful storage in special containers. Fittings that can normally hold water and air under pressure may still leak hydrogen because it is the smallest element. Hydrogen storage is rocket science.
In order to produce sufficient quantities of hydrogen for use in a fuel cell vehicle from solar cells, you would need to invest tens of thousands of dollars in a solar array alone. Beyond that is the space that such an array would require (I'll let you do the math), electrolysis equipment, and professionally maintained containment systems. This is not a one-time investment. Fuel cells wear out just like regular rechargeable batteries do. Solar panels also have a useful life after which they must be replaced.
I have no love for the oil companies, by the way. I believe their days are numbered. There will always be some oil in the ground somewhere, but when it costs more energy to extract a barrel of oil than the energy gained from using that barrel of oil as a fuel, then the oil age as we have known it will cease to exist. This is known as Energy Returned on Energy Invested (ERoEI). Oil extraction back in the 1930s had an ERoEI of at least 30 to 1. Today, the ERoEI is much lower due to water injection, deep sea exploration, and refinery costs.
On our planet hydrogen doesn't exist freely outside of molecules. Some of those molecules contain stored potential energy. They are usually referred to as hydrocarbons, molecules containing hydrogen and carbon. They include natural gas, oil, and coal. These substances are extracted from the earth's surface, and the energy gained from them has been far higher than the energy used to extract them. This has been the basis of our industrial society. Hydrogen is found in abundance in water. The water molecule is an energy sink. To break it apart takes lots of energy. It is not a fuel. There is no such thing as a perpetual motion machine either.
I know that this post will come across negatively. I'm sorry for that. These are the facts. There are alternatives that do work, at least for the time being. Electric cars that run on batteries are available now. People have converted older cars to run on common batteries with electric motors. Another alternative is biodiesel or even used vegetable oil. Again, people have made conversions to existing diesel engines to run these alternative fuels. Transportation doesn't have to be rocket science.
