Re: ~e; GM u-turns on hybrid-electrics

thanks Howard for writing more about General Motor's
hybrids, and their fuel cell developments. I had no idea
they had a residential fuel-cell in the works, but have
heard about interfacing the natural-gas infrastructure
with fuel cell cars, prior to a hydrogen system being in
place. there are a few questions that I wonder about...
- I was on a list for decentralized electrical production,
and approached it with little technical knowledge, and
was not able to comprehend what seemed to be an
ongoing argument about using smaller-scaled generation
systems (local fuel-cell powerplants, for instance) because
of their special needs, and also needing to deal with issues
of electrical power conversion, I am not sure exactly what,
but I thought it had to do with AC/DC or something like this
which also is relevant with home solar and wind power.
- agreed, whole-heartedly, about GM's efforts both in the
fuel-cell realm and hybrids, and it is hoped that both can
be beneficial, and in their different markets (in transition).
- I once knew of- and have since forgotten- the response to
a supposed-aversion to 'hydrogen' fuel-cells & the Hindenburg
effect (I think the CEO of Ballard Power Systems may have
brought this up as an example in a television interview, even)
about hydrogen fuel cells exploding when in car crashes. It
may be that it is pressurized and when released from tanks
is gone into the atmosphere quicker than an explosion can
occur, but if you've heard this argument, it would be interesting
to know more about it, and how it is addressed.
- my one big curiosity with fuel cells (and, if it is true of all
is their emission of water as the only by-product in creating
power without traditional combustion and gasoline side-effects
of carbon-dioxide and pollution. from exploring science, techno-
logy, and society a bit, it has me skeptical as to what the negative
effects of most technologies are, and, what it might be for fuel-
cells, so they might be acknowledged and optimally designed.
for electrical vehicles, for instance, there are issues with both
powering the vehicles (by powerplants that are fossil-burning)
and also battery-replacement and disposal, at this point. for
fuel-cells, my only guess is that- with all the crazy weather
patterns going on- if a major transformation happened and
more water (via millions of fuel-cell cars) were put into various
environments, how might this effect humidity levels, snow,
weather patterns in general. this might not even be a negative,
at times. it just has me stuck here, as a question, wondering.
thanks for sharing your thoughts. brian
