I do a lot of reading. I was reading about hydrogen fuel cells and the future. One of the place I was looking at is Howstuffworks. Anyway I came across this little car kit and order it.
This should be fun to do. What da' think? [:D] Now if I could just get a kit large enough to replace the work vans... LOL [^]
http://www.discoverthis.com/fuelcelcaran.html
<b><font color="blue">What kind of fuel cell does the Fuel Cell Car & Experiment Kit use? </font id="blue">The fuel cell uses a Proton Exchange Membrane or PEM fuel cell. PEM Fuel Cells utilize the energy from the electrons given up by hydrogen ions (or protons) during the reformation of water across the membrane to run the car's motor. The fuel cell is "reversible" meaning that it can both split water into hydrogen and oxygen, and combine hydrogen and oxygen into water.</b> Interesting to say the least.
<b><font color="blue">How often do I need to replace the water in the fuel cell? </font id="blue">
Not very often. Because the fuel cell is a reversible fuel cell, the water gets split into hydrogen and oxygen during electrolysis and then that hydrogen and oxygen are re-combined back into water. The water can be used over and over again. Of course, you will lose water to evaporation and spilling, and thus you will need to replace the water periodically.
</b> Neat-O~~! UH? One quart of distilled water and 10,000 miles to go....LOL!!!

Pretty slick. First time I've seen a reversable fuel cell sold as a hobby kit. The PEMs are getting a lot of attention, since a number of laptop vendors want to put them in their computers.

Well, there is the efficiency factor. Solar is not that efficient; it is going to take awhile to make it worth it versus other energy sources. I have been in this business a long time, with windmills out my office window by the thousands. No easy solutions. Hydrogen has to come from somewhere. Currently it is natural gas (which is at all time high). Electrolysis is very expensive (electrical costs plus inefficiencies of conversion). Now if we only had controlled fusion...[:)][:)][:)]

a n s,
Tell us something. And please forgive me here for my pure IgnOrenecz. Where does hydrogen really come from as far making mass quantities of it? I have heard that the oil companies will still have a roll in producing it. Is that correct? And is it that plentiful?? I know this is a dumb question... All I do is deal DeltaV, Mr. Newtons laws and the results there of so this is totally out of my realm and sure have not thought about it since school.

If a man says he knows anything at all, he knows nothing what he aught to know. But...
MallardWacker,
Currently, the main industrial process for hydrogen generation is steam reforming of natural gas. Basically, you are pulling the hydrogen out of the methane. So yes, the oil/gas companies will be involved in hydrogen supply. The problem now is that we are building a lot of natural gas fired power plants (using natural gas as a power plant fuel was actually banned by Federal law for quite some time; saving it for petrochemical use and home heating). With that, demand (and price) are now up quite a bit.
This is why there is renewed interest in LNG (liquified natural gas) tankers and terminals. This is also why nuclear is getting a second look, since at very high temperatures, you can directly break water molecules into oxygen and hydrogen (as well as use electrolysis, but that is less efficient).
Arcs_n_Sparks
So what you are saying this hydrogen thing does not have an endless type supply. I guess I haven't payed close enough attention to the fine print. Arcs am I missing something here? It has advertised as a silver bullet or something.

MallardWacker,
Yes, most people miss the fine print on hydrogen (more accurately, they don't ask the question you did: where does it come from?). Currently, it comes from fossil fuel sources, and has roughly the same supply and environmental concerns as those fuel types.
It gets worse if you go to electrolysis (say for home-based hydrogen generation). Unless the electricity comes from nuclear, you have the expected environmental emissions from the power plant, plus the inefficiencies associated with electrolysis.
So, the recent Honda ads with water dripping out of the tail pipe are nice, but fail to tell the entire story. Hopefully, this is not more than you wanted to know.[:)]

Thanks arcs,
Nice to know that we can count on the government to keep us well informed. Also, how come the tree huggers are not screaming this. It took them a while about the rechargeable electric cars and the impact the batteries had, I think they were too busy watching Ed Beagley Jr. driving his battery car all over Hollywood.
But if it takes less fossil fuel per mile to produce the hydrogen cars, I guess that is better. About the water, I do agree that is better for the air, I am still not sold on the THEORY about global warming. When I was in high school, the great fear was global freezing and the earth was going to move off it's axis and the only folks that were going to live was the ones on the east side of Pikes Peak.
Sorry for getting a little political there, please forgive me. I don't usually get that gun out of my holster.

Phone Guy,
I have met Amory Lovins of the Rocky Mountain Institute; we had a pleasant meeting. However, MallardWacker's question was more along the lines of main stream hydrogen supply, and that is steam reformed methane. There will always be "boutique" methods of alternatives (which may or may not reach fruition on a large scale (like coal gasification)). I remind people that Californians use well over a billion gallons of gasoline per month during the summer peaks, so if your solution "only" provides 10 millions gallons of alternative fuel per month, you are at least one order of magnitude away from making a difference, and two orders of magnitude away from making a change.
Out my window at work I see thousands of acres covered with windmills; they would not be there without price supports and tax credits. Their entire output could be replaced by a tiny power plant tucked away where no one would see it (and if the environmentalists in California have their way, that will happen, since they kill birds of prey).
As I tell my friends, no easy answers, just difficult choices. I keep working on providing options for difficult choices. However, the choice this weekend is easy, I'm smokin!!!!!!!

Correct me if I'm wrong, but it seems to me that in the past couple of weeks in my local paper it stated that Brazil was pretty much no longer dependent on oil. They started a program back in 1991 and today it has paid off.
Now if they can do it why can't we?

My understanding is that the hydrogen cars we have now will work just fine. The problem is there are no filling stations. What do you all say we take a vote.
1.) We go to Mars.
OR
2.) We put up some filling stations first.
I vote for #2.
Yes it is true it will take some form of fuel to create the needed electic to split the stuff out of water. However, I also know it is true that hydrogen is a major bi-product of many industries.
At my age if my next car runs on oil or hydrogen it will not make any difference. However, many of you are not my age. I fully believe it will make a difference to your children.... I sure hope everyone feels this way. What we do in the next 5-10 years will really effect the next generation. More so than in any point or time in history.
We are a "Super Power" that cannot even pay its own bills. The Chinese are. If you don't believe that then go find out who is buying up our paper. I believe that if we move quickly we can buy back our country. Oil is not part of that solution. If the American People don't take a stand, then those who don't do not deserve the type of American Life I have enjoyed. In fact it just will not be there. You will be drain dry through payments alone.
The greatest end result of not having to use oil, beside taking back our real estate, is we will no longer have kids dying in the Middle East.
We, errrr let's make that You-All of younger age, need to make this happen. It is your lifetime that will see the pivot. Not mine.
There is an old idea I live by. Save a Buck. One day there will be many dollars saved. If what we can do today will only shave off 10% of our need for oil... then one day there will be much that is no longer needed. Save a Buck!
You have to start somewhere.

A good overview of the energy situation in Brazil is here: http://www.eia.doe.gov/emeu/cabs/brazil.html
The Cliff Note answer is increased domestic production to narrow the import gap (on track to be self-sufficient in 2006). Also, eliminated the government oil monoply in 1995, which spurred competition.
Did not mean to imply not working alternatives; been doin' that a long time, and it needs to be done. Just pointing out what I call the "valley of death," bridging the gap between novel new ideas and the reality of what people and markets expect.

I am an anti environmentalist. I think we can do with a lot less of them. I also am a proponent of nuclear energy. I don't believe there has been as many deaths (in the USA)caused by nuclear power plants as there has been by petrolium products. Look at the environmental impacts of an oil spill. Don't get me wrong, I don't think it's the end of the world if a spill happens. Our earth was designed to clean itself up in a matter of time. I think we should have nuclear powered autos also. Yea I know the uranium could pose a problem.. But if you built the little reactors out of the same stuff as the Black Boxes on airplanes what could go wrong?[:D]
Seriously I think the media and the environmentalist groups have put this fear of nuclear energy in people thats hard to over come.
This reminded me of something my DAD told me about many years ago that he heard a local news person say during a heat wave that SoCal was experiancing where a number of people had died.
"All you Jane Fonda fans: Solar Energy-four deaths, Nuclear zero"

Want to reduce our oil consumption? Check these facts..
Nuclear Power
Conserving Resources with Nuclear Power
Did you know that nuclear power is one of the cleanest ways to produce electricity? Nuclear power plants do not burn fuel. Instead, they use fissioning uranium atoms to produce the heat needed to operate the plant.
Nuclear power plants do not produce airborne emissions like carbon dioxide, sulfur dioxide or nitrogen oxide. In fact, between 1973 and 1989, using nuclear power to produce electricity reduced worldwide C02 emissions by over 13 billion tons! Countries like France that rely heavily on nuclear power generally have much lower carbon dioxide emissions than countries relying on fossil fuels.
Using nuclear power has enabled us to use our fossil fuels more sparingly. Since 1973, <b>nuclear power has reduced the use of oil for electricity by 17.6 billion barrels</b>, coal by 2.2 billion tons and natural gas by 26 trillion cubic feet.

I am sure that Olds is working on a nuclear heater and fan assembly for our Bradley smokers right now, and I am sure we will be able crisp that skin on the chicken when it is finished. Our pets that are hanging out waiting for us to drop something will all have 5 or 6 legs, two tails and a cyclops eye in the middle of their foreheads.[:D][:D]
I personally would like more research done with Solar. The reactor at Rancho Seco is a life long tribute in my area to scientists not able to get it right. Nuclear power plants will certainly save fossil fuels, but takes it toll on the enviroment in other ways that are far more difficult to manage.
Sun power and storage cells, although not as efficient in short term gain, certainly would be safer and less intrusive.
Bill
<i>There is room on earth for all God's creatures....on my plate next to the mashed potatoes.</i>
I have to agree with Bill about nuclear power. You have Rancho Seco, here in New York we have Indian Point. What were these people thinking?!! Building a nuclear power plant on top of a fault line. I'm so lucky I am out of the 50 mile evacuation radius; I'm very fortunate that I'm in the 53 mile zone.[;)]
Phone Guy,
You should like this web site: Adams Atomic Engines http://www.atomicengines.com/ The link to Atomic Energy Insights has some interesting reading.
For awhile I was working on a 100MW, 35-40 year life sealed core reactor. No refueling, so reduced proliferation danger and waste issues. Toshiba is working on a 40MW version for up in Alaska. Diesel electric power there is both expensive and dirty.
