I'm 62, I'm lucky to average 6 mph in city traffic,
but that's not using the proposed vehicles, either,
with all their energy use improvements, just an
unimproved 18 speed heavy working bicycle
pumped by geezer muscles.

So, that low average speed seems to be in part due
to the poor energy efficiency and aerodynamics of
current commuter bicycles, yes?

I don't think a much more efficient solution should
be condemned for slowness until there is some
real data with which to work.

Quoted message said:

Practical performance parameters for a light
electric (enclosed) vehicle: 250lbs, 30mph

Such a car would be adequate for the majority of
trips that 6,000lb SUVs are currently making. The
car would have ~2kW motor so 100W or so of pedal
power that could be added wouldn't amount to
much... and wouldn't be worth the added
complexity.

Unfortunately, that still runs on fossil fuel, just
indirectly as it is burned in the power plant. That
only solves part of the original problem, as all
energy supplies seem to track motor fuel prices
fairly accurately.

I live in a city (Phoenix, AZ) which is 90% level
ground, ideal for bicycle commuting [granted the
heat is a bit much, I did a six mile each way
bicycle commute here in the heat of the summer with
no particular trouble, in 1996-1998]. However, the
few bicycle lanes are poorly designed, disconnected,
and have very poor signage. This city is now
installing a light rail system, which I predict will
be wildly unsuccessful; it won't move any faster
than automobiles, since it will have to stop at the
same stoplights interrupting automobile travel. In
fact, of course, it will be much slower, because it
must consume time at waystation stops. Commuters
will be staying away in droves.

How much cheaper and easier it would have been just
to clear the same pathway and assign it as a (two

Dear Kent,

For what it's worth, the Varna Diablo rider uses a breathing mask and
a wheel doing double-duty as an air pump to cope with ventilation

Thanks for that URL.

I was fairly sure the community expertise could help
flesh our my non-expert proposal (which started in a
dream, from which I woke up and continued to extend
the ideas already sleep-provided).

Of course, that also lends credence to Ron Ruff's
suggestion that nothing close to those speeds will
ever be achieved in commuter human powered vehicles,
though I'm hoping he's wrong.

If a "super-aerobic" athlete can pedal for five
minutes and achieve a top speed of over 80 mph / 128
kph, I'd like to think I could achieve a quarter of
that speed for six times that long, even at my age.

I did push and pedal a bicycle for 400 miles towing
450# of luggage through the desert a year ago, so
I'm probably in adequate physical condition to
attempt such a feat.

Moreover, and back to the original proposal's goals,
I think that the ever increasing feeling of
well-being that the many obese Americans would have
when they began using their bodies in ways that
reduced their obesity (I lost 37# on my journey)
would make up for the minor annoyance of the need
for a shower at the end of the commute each way.

Enclosed bikes for commuters have been around for a long time. Do a

The obesity problem is mostly psychological... an effect of the

You are right. But Yodah says: Hold not your breath, Young Ron, until

The only hope is an extensive system of bicycle paths. And the usage
there of is somewhat at the mercy of the weather. Try riding a bike into
the teach of a 40 mph gale blowing cold rain, snow or sleet.

There you go again, being logical.

Even with bike paths, weather is a limiting factor. When there is glare

I agree 100%. Even here in Boulder, not all 'main' roads and most
smaller roads don't have a bike lane, shoulder. If bicycles had their
own lane/space, not only would it be used more, be safer, there would
be less car-bicycle shouting matches...Not good in Boulder country, try
Macon GA or any other place, USA, where bicycles are toys, not
vehicles.

Lowering fuel consumption is vital to making the economy sustainable.
A good way to use less fuel would be to have suburbanites move back
in to the cities, so they wouldn't have to drive so much.
The inner city poor would have to be relocated to make room.
First, we would have to legalize drugs to take away the black
market jobs. Then, we would need to offer them jobs and
housing on farms and factories outside the cities. That way,
more food and goods could be produced locally, for additional
fuel savings.
But if the population keeps increasing, all bets are off. No,
we have to freeze, and eventually decrease the population, too.
A good starting point would be to stop suppressing influenza.
To those who would object, I point out that we're living much
better today than even royalty did centuries ago. There should
be no complaints about having limits to longevity. There are
other creatures and future generations to think about here too.
Sustainability is all about justice, not "just us."

That's not what happened. The US set mpg

of weights which were intended to differentiate
individual consumer passenger vehicles from, say,
panel trucks. The SUV manufactures just made their
vehicles weigh more than what had been thought to be
the upper weight limit for an individual consumer's
passenger vehicle, exempting _themselves_ from the

and SUVs were put forth to satisfy what consumers
wanted, not what government told them they should

Today, the reality has shifted markedly, to the
point that high fuel costs have made SUVs a drug on
the market at car rental companies, who are now
renting SUVs at low fire-sale rental rates and
fuel-efficient subcompacts at premium prices.

That's a pretty big hint that the driving public is

The electric motors on these are secondary... the gas motor is powerful

Last I heard our present gas prices are not high enough to
significantly curtail gas consumption. There is also no mad rush to

gas pushing people to ride bikes.

How do you manage to lose the transmission and gearbox? You still have
all the parts that a gas vehicle has, plus the complete electric
subsystem. They are inherently more complex and expensive (and
heavier), and their increased cost does not compensate for their fuel
savings even at todays prices. By contrast, the power train of a small
electric is just an overgrown alternator, a battery, and contoller...
very simple.

And why do people want what they want? Bigger is better. Most people

The *correct* use of government is to enact laws that support the

everything... but often for the greed of the few rather than the good

requirements on the manufacturers was a good solution. That way the
more fuel efficient vehicles were effectively subsidized, and the less
efficient were "taxed", and it gave them an incentive to make fuel
efficiency a priority in design.

Naw, it ain't so bad. The worst things about slush are: it sticks to
the chainstays and traps salt, etc to forment corrosion; it's slow to
pedal through; and it lets debris stand upright, causing more flats
(and a cold slushy aluminum rim is not a pleasant thing to lever a tire
off of.)

Glare ice on the ground itself is rarely an issue. It's a total loss if
the city allows contractors to cover large holes with steel plates, or
if poor drainage causes *thick* ice that extends for more than a metre
or two.

Non-glare ice is worse - especially the lumpy ice that forms under
parked cars, on the south side of E-W streets that ban parking during
rush hours. Car drivers expect you to ride in the apparently empty lane
on your morning commute, but it's basically impassible. In those
conditions, I wear lights and bright colours, and hug the left side of
the right lane, and make sure my brakes are warmed up.

But those last two items aren't weather, they're maintenance issues.
Last winter, I found if I took a route that went cross town one major
block north, I could eliminate the steel plates and lump ice. The
alternate street was wide and had large set-backs and they didn't allow
parking, so that there was room to manoever around the utility cuts,
and the lump ice didn't build up due to a lack of parked cars and a
healthy dose of afternoon sunlight.

I've stated it here before, but icy weather affects commuter trains
more than it affects commuter bicycles. I've been the only one to make
it in to work on time many times over the past 10 winters.

Lowering fuel consumption is vital to making the

cities, so they wouldn't have to drive so much.

How about you learn how to resist the urge to
introduce photocopies of your fascist state
solutions to problems that can solve themselves very
nicely without your help, into every discussion
where they can be somehow wedged into the
conversation, however inappropriate?

How about underwater cities? Then we can commute
by submarine, and given your experience, you can be
a Mr. Big Shot _for real_, instead of just in your own
little mind!

How do you manage to lose the transmission and

vehicle has, plus the complete electric subsystem.

Probably it's not worth continuing this conversation
until you correct your misapprenhensions about
existing hybrid auto technology. Both of these
statements indicate really bad misunderstandings of
how modern hybrid autos work.

Yes, the gas motor _can_, theoretically, take you up
a steep grade alone. No, the experience will not be
an acceptable driving experience, as it will be done
at a slow walking pace. That's if it works at all;
there's no way to gear the motor down independently
of the hybrid electric system, where the throttle
control has its effect.

No, modern hybrid electric cars do not have
gearboxes, and do not have transmissions. The motor
isn't connected to the wheels by any mechanical
means at all except the frame; it connects to an
(integral, I think) generator which connects to the
rest of the electrical system.

I did push and pedal a bicycle for 400 miles towing
450# of luggage through the desert a year ago, so
I'm probably in adequate physical condition to
attempt such a feat. Moreover, and back to the
original proposal's goals, I think that the ever
increasing feeling of well-being that the many obese
Americans would have when they began using their
bodies in ways that reduced their obesity
(I lost 37# on my journey)

How much of that 37# did you gain back since, Pigpen??

I think you need to do a little homework. Existing hybrids use parallel
ICE/electric systems... meaning that power can be supplied directly
from the engine and electric motor either separately or together. This
is accomplished with a CVT (continuously variable transmission).

Here is a tech page on the Prius... by far the most successful hybrid.
I don't see anything about it that is simpler than an ordinary car...
all the electric power features are additional.

You are thinking of a *series* hybrid (yes?) where the engine+generator
only charges the batteries and/or supplies electric power to a motor
which drives the wheels. This design was considered many years ago and
found to be lacking in efficiency and utility. I don't know of any
current working examples... certainly none of the production vehicles
are made this way.

Oh, fat cells are easy to get back; I'm about 10# under where
I started.

So, tell me, how many of those brain cells you poisoned with
long time alcohol abuse have you grown back, O dancing
blue-butted baboon sociopathic megalomaniac?

Gods do you leave yourself open for zings by your sheer stupidity.
Your planning skills don't exceed those of your typical toddler, a
major reason your society planning is received only by guffaws
and gibes.

The new paradigm reflects a growing awareness of how chronic
distress affects the brain. Our stress-hormone system, which
kicks us into action in an emergency, may remain switched on
in susceptible people, especially those who were very stressed
during childhood. Overexposure to stress hormones slows the
growth of nerve fibers in a region of the brain called the hippo-
campus. This brain center allows us to soak up sensory input,
link experience to emotion and store all of it as coherent
memories. The hippocampus is typically small in depressed
people, with some brain cells lost and some shrunken. Experts
suspect it is one of the structures central to the condition.

The idea that depression is linked to stalled nerve-cell growth
or faulty connections may explain an old mystery. If antide-
pressant medications boost neurotransmitter concentrations
immediately (which they do), why does it often take six weeks
or longer to feel better? Recent experiments in mice tell us that
antidepressants stimulate the growth of new hippocampal
nerve cells, which form new connections with older nerve cells.
This process takes several weeks. If drugs like Prozac ease
depression by inadvertently boosting neurogenesis, the think-
ing goes, drugs designed specifically for that purpose might
bring surer relief while causing fewer side effects.

[pointless shovelware quote having nothing to do with brain
damage and nerve cell death due to acute chronic alcoholism
poisoning, or recovery therefrom, snipped]

So I guess your answer is "zero", but you have too few intact
brain cells left to express that answer in your own words?

I am not at all surprised by that implication, and you answering
with shovelware quotes you cannot read with understanding
seems to have become a "law of the universe" ranking with
the laws of gravity and the electromagnetic forces.

Heh.
