You were against high jerk aircraft and now it appears
you oppose low jerk vehicles.

Newsgroups have charters.  
Newsgroups have recommended guidelines for
posting.  The first guideline, is post to only one newsgroup.  

Unless ignorance of a poster needs to be exposed.
The ignorance of a poster is not your responsibility. You do not have
a big red S on your chest. In this case, from post #1, you posted to
off topic newsgroups, namely alt.g-w. It is your ignorance being
highlighted. And even after pointing this out, you continue to
violate the guidelines.

In that case your only hope is to proffer some calculations or
reasoning or everyone will be able to see you can't do 2nd
year level engineering.
Why would you want to do this, in front of God and everybody? And
then feel you were qualified to expose the ignorance of posters?

The
second guideline is if the topic of discussion is really
also germaine to another newsgroup, then add another
one.  

AGND (ain't got no data) climate change deniers are a
staple on alt.global warming.
Which has fuck-all to do with accel/decel control sytems on buses et
al.

Climate scientists need to know that there are also
have AGNC (ain't got no calculations) technology deniers.
And are you naive enough to believe your crossposting to unrelated
newsgroups will change any of that?

No you are clearly posting only for attention, like a little child
throwing a tantrum.

The first hole in the atmosphere I read of in the press was claimed by a
group of Turkish farmers who sued the US ans USSR for poking holes in
the sky with their rockets, thereby washing out their crops with
excessive rain. For what it's worth, most of the the maps of the ozone
holes that I saw were in polar azimuthal equidistant projection.

Right now that "gallon" represents over 8 lbs of carbon, 29 lbs CO2.

A bus is 4X better than a new Prius with one occupant.

A "standard" passenger car with 1 occupant managed to get 100 miles
per gallon. Big deal with your bus. It takes me across town just as
fast as a horse would. How many gallons of fuel does a horse burn?

Right now that "gallon" represents over 8 lbs of carbon,

In the Universe I live in, and gallon of "gasoline" weighs in at a tad
over 6 pounds, which is less carbon, and less CO2. Again you spout
without thinking.

You are endarkening them.  
Just because you AGNC (ain't got no calculations) and AGNR (ain't got
no reasoning) on low jerk throttle controllers doesn't mean others
aren't interested in making rideability improvements to low carbon
public transportation.

You have no real ideas.  
You are starting to project almost as much as a "libertarian."

Next you'll be dodging questions.

Might as well get started with the question dodging right now.

What are your best ideas?

.. . .


Buses get 200 passenger miles / gallon.

A "standard" passenger car with 1 occupant managed to get 100 miles

Why isn't it commercially available like public buses?

Anyway we are back to carbon reduction.

Just because you want to remain ignorant about improvements to low

posters, aka "alarmists" on alt.global-warming aren't interested.

Not that you ever provided any calculations or reasoning one way or
another but you seem to have abandoned your objections to the
feasibility of low jerk throttle controllers.

What happened?


Bret Cahill
 
mass on a spring, pendulum

well, some of that is obvious,
even though I've never thought of it, before;
what do you mean by harmonic motion,
applied to wheels?



If you do this with simple harmonic motion the highest absolute value
of jerk coincides with 0 accelleration and vice versa.
Going from parked [zero accelleration zero velocity] and then trying
to accelerate into traffic while keeping jerk low.

And rule # 1 is to stay off threads which don't interest you or

Some railroad reg. requires a passenger train to decelerate with a
jerk<  2 m/sec^3.  Don't how or even if they do it on trains but it's
a good idea to keep the jerk down when passengers are out of their
seats and walking to an exit.

It could be done automatically on public buses to reduce tumbling down
the aisle incidents.  It would also reduce the multi tasking load on
bus drivers trying to pull out into heavy traffic before passengers
are seated..

The brake pedal would have an override, i.e., stomping all the way
down, in case a pedestrian stepped out in front of the bus.

The number of elderly will soar along with fuel prices so this will
save a lot of lives.

I do not believe you have:
  1. observed the problem set in the field
  2. correctly identified the actual condition of maximum hazard
  3. considered "Law of Unintended Consequences"- Hide quoted text -
Try googling low jerk and "throttle controller."

Poles are points on a polar azimuthal equidistant projection, not
singularities.

When was the last time you saw 4 passengers in a Prius?

Anyway by 2015 Freightliner will have a rig that get's 174 ton miles/
gallon. Figure the average bus passenger in the U. S. weighs 0.2 tons
so the newer buses will be able to get 870 passenger mpg.

Now if we can only get that going with every day commuting then a
Prius could compete with a bus.

Each one takes up two seats so the 870 passenger mpg figure may be a
little high.
