Everyone knows that Fuels Cells are
this great technology. The only
problem is how do we get hydrogen
for them? The answer is simple, Each
city with the capability to create a
hydro electric dam could do this.
Take St. louis, Missouri for example,
you build a hydrelectric dam and you
use
the water from the river to splice
the hydrogen molecules off to make
hydrogen, but this process takes
energy to do so, but in stead of using
fossil fuels for the electricity so this
doesnt help the enviorment. But
becasue you have a hydroelectric
dam right there you use its own
energy to make the electricity to
slpice the hydrogen off of the water
and bam you have your power source
for a fuel cell. So you have these
hydrogen plants right in the heart of
your city inside of a dam and then
you have a local pipeline that gives
hydrogen to all of the hydrogen
dependant devices cars etc. No more
importing and being dependant upon
oils prices which keep going up and
up. Your own city does it all locally
and better yet it would help the
economy, people get jobs for building
dams maintaining them, building
pipelines. Only downfall is the effects
of the river wild life, will more dams
effect it in a negative way?

hwo would you do it? have a pool
of water and use power from a coal
powerplant to slpice hydrogen
from water? My way the dam
makes the power it has the water
right there, then uses the power it
makes to slpice the hydrogen from
the water which is right there all
around the dam. Then a pipeline
comes from the dam and supplies
the entire city. Seems pretty dam
efficient, all of the energy made all
in one place. |

Okay, hydrogen didn't *start* the Hindenburg fire, but it damn sure made a good finish of it. Back to the idea... |
|
| |
Why not just use the electricity to charge batteries which, in turn, run automobiles? Also, I think you'll get a bit of resistance from the people of St. Louis if you were to tell them you wanted to dam the Missouri. Not only would you flood the city out, but you'd destroy all commerce up and down the river. |

One of the advantages of hydrogen fuel, or any chemical energy medium, is that it is relatively efficient to transport over large distances. The disadvantage to electricity is that transmission losses are proportional to distance transported. Any time energy is converted from one form to another, losses are created. |
|
| |
If you have a power source in the middle of a city, it is a prime opportunity to make electricity, as the transmission losses will be small. Using a centrally located power source for conversion to chemical energy is a waste of that opportunity. |
|
| |
Power centrally converted to chemical energy, transported just across town, and then converted back to electricity, adds one more step of conversion and one more point of losses. |
|
| |
Also, most rivers that can be used for electric generation already are, at least in the sorts of parts of the world where people would also use a hydrogen energy system. I don’t think that St. Louis is the sort of a place that can get hydroelectric power from dams because there isn’t enough head. |
|
| |
the missouri allready has
hydroelectric dams. They are part
of the lock and dma system. You
could just use that. |
|
| |
I’ve looked into it now, and while St. Louis head isn’t that great, the volume of water is very large. (I was distracted by watching so much water go over the spill way, forgot some of it got used.) And indeed, many of the lock and dam structures incorporate power generation, but that makes it seem like the electricity is spoken for. |

Hey! Enough knocking St. Louis
already! |

Redox power has a methane based fuel cell that may be effective for domestic use. |
|
| |
Methane gas fuel cells because it is a more common fuel. |
