The economy is doing so-so at best. We have a mixed collection of
measures of it.

The collection is always mixed--it's quite impossible for all sectors
to simultaneously prosper, as many are competing.

Overall, growth, employment, etc. are as good as it gets. If you're
not happy now, you never will be.

Everyone was holding their breath.

My theory? Politicians, flying in their private jets. ;-)

You haven't looked closely enough. Right now the US is running a
large deficit and has quite low interest rates. These are both things
that in the short term stimulate the economy. It is like a car with
the gas pressed all the way to the floor and only gets up to 45 MPH.
It is a lot faster than I can run but still a lot less that should be
expected.

Exactly how fast do you think the economy should grow? The Federal
Reserve Board has been trying to *slow* the economy since mid-2004,
and that's still their focus today. Perhaps you should e-mail Mr.

It isn't the growth rate that bothers me. The car is going 45 MPH
that is a reasonable speed. It is the fact that the the foot is so
close to the floor that worries me.

As for the deficit, I don't like it, but find it hard to understand
why you think it's related to GDP, or why 3% of GDP would make any
difference in the short haul. It won't.

I either don't understand what you are trying to state there or you
are trying to say that something that is well know to be true is
false. I will let you restate the above.

I understand you believe these things. I invite you to show the
quantitative basis for those beliefs.

It would help if you define some of your terms--what is "middle
class"?

The middle class usually taken to be the socioeconomic class between
the working class and the upper class. They are the businessmen and
shop keepers etc. Working class are those who work for a wage (ie:
most of the people). Of late, however, the upper end of the labor
class has taken to calling its self middle class.
What is "standard of living"? Do you mean that real wages
have decreased?

If they are collecting wages they really aren't middle class taking
the classic definitions. But as many americans would define it, yes
that would be included in the decrease.

Kindly show that. Be sure to include benefits--
retirement and healthcare in your figures...the result may surprise
you.
I doubt it:

Smart business folks are starting to prepare for the decrease as in:
http://www.foodprocessing.com/articles/2005/404.html

Between 2001 and 2004, there was a 10.5% decrease in the portion of
the middle class that had three months of wages in economic wealth.

Average household income for working families when adjusted for
inflation was $46,058 in 2000 and has since declined to $44,389.
There has also been a decline in the average value of benifits.

This article (below) shows the debt or decreases in savings to
maintian the life style.

The article below makes the point about the growth being less than
should be expected. The numbers are at the bottom.

Do you have any figures?

The US has a decreasing size of middle class. The working class is
seeing a net loss of standard of living. Most of the middle class is
also seeing a decrease in standard of living. The debt is piling up
and the average worker age is increasing. None of these are things by
them selves would be a major problem but combined they point to a
decline.
There is also a serious concentration of power and wealth happening.
The trend is towards a small number of companies being a big fraction
of the economy. This is never a good thing for the long term survival
of an empire. It leads to a fragile situation. With many small
companies, a mistake only impacts a small part of the economy.
Increasingly, a mistake by a company impacts a larger part of the
overal economy.

I understand you believe these things. I invite you to show the

Europe looks good, until you consider their demographic time bomb:
declining number of workers, increasing retirees, and unfunded
retirement comittments:

http://www.iht.com/articles/1996/01/27/oc.t.php


As far as the US goes, almost everybody has a personal choice about
how hard they will work, how much they will spend, and whether they
want to save or whether they want to blow money on cars, plasma tv's,
junk food, and vacations. It's a shame that so may people run up debt
to buy crap, and have zero or negative net wealth, but it's their
choice.

Another "how to lie with statistics" demonstration... percent of WHAT
net average income?

8% of $50K sure beats 12% of $25K

Yes and this is a further problem for the US to plan for. If the
economy of europe takes a dive, it won't be good news for the US
economy. Much more is linked these days.
declining number of workers, increasing retirees, and unfunded
retirement comittments:

The US also has a huge problem with unfunded retirements. The Pension
Benefit Guaranty Corporation puts the federal government on the hook
for any failing defined benifit retirement programs. There are quite
a few of these. They are thought of as private retirement programs
but they are a case of privatizing the profits and socializing the
costs. By promicing more than the funding could really support,
employers bought themselves lower labor costs.

Federal Deposit Insurance Corporation protects normal bank accounts.
I don't see too much load being put on that system but there may be
some caused by the retirement bubble.

The 401Ks etc are largely invested in the stock market. As the bubble
retires, those stock should slide down a little. If the federal
government is forced to raise interest right at the same time, there
will be trouble. The economy could get a very serious hit from that.

Yes it is their choice. Unfortunately, their choices are likely to
effect you and me. I have had enough to retire on for many years. I
am a little more heavily invested in earthquakes that I really should
be but I don't see any safer place to move money to.

So you drove 70 mph between fillups?

I did (well, 75mph most of the way) for ten hours Wednesday. The
only stops were for gas and water. I only wish I got close to 26mpg.

It is a question of storing energy that was at issue not of taking
it from place to place. In a car the tranfer of power is well
handled by the mechanical transmission.

For energy storage in a hydraulic system, hydro-pneumatic
accumulators
are the most commonly used accumulators. The energy is stored by
compressing the gas in the accumulator. This is the path the US
EPA took on this:

http://www.epa.gov/otaq/technology/420f04019.pdf

The elastic bag in hydro-pneumatic accumulators accounts for about
half of the stored energy. Surprised me when i did the calcs.

Yes that surprises me too. It still will store a lot of energy per
pound in the air part. Compressed air has a lot of nice qualities for
this sort of purpose.

Nope.
Energy per pound storage is trivial compared to alternatives.

Energy per pound is also totally meaningless for terrestrial auto aps.

Start with any thermo book and read example problem #1 on isothermal
versus lossy air compression.

Hard to reach 15 watthours per liter and 60 percent efficiency.

I assume you have a number to back this up. Remember it is energy per
pound.

You are wrong here. The problem with the lead acid battery is its
weight not its size.

Start with any thermo book and read example problem #1 on isothermal
versus lossy air compression.

Hard to reach 15 watthours per liter and 60 percent efficiency.

... and yet the hydraulic hybrid autos seem to be using it to store the
energy

Don is right. I have designed many pneumatic systems with energy
storage. Storing enough to bring a bunch of pneumatic actuators
to a safe position on power loss is easy. Storing enough to be
a practical energy source for a car? Not at all practical. Not
only that, but it would make an excellent bomb just waiting to go
off in a crash.

Storing the energy of braking to a stop so as to give it back
when you accelerate requires a lot less energy storage than
storing enough energy to replace the engine. It's well worth
doing in the case of a delivery truck, but it isn't a practical
replacement for an electric car.
 
A story:
Some years ago, I'm entering a Safeway, a
pretty girl accosts me, she wants a signature
on a petition to nuke the baby seals or
something. I retort: "We have enough taxes
and feelgood ecoprograms, I'l pass."

She answers: "It won't require new taxes, it
willl be funded by bonds."

Yes folks, a breakthrough in political economy...
gubmit programs can be paid for with bonds,
NO TAXES NEEDED.

She was sweet and earnest and dim, a
concerned citizen.. and a voter. Scary, huh?

There's nothing superior about driving on the right. Have a moan at Japan,
Australia, India, New Zealand, India, South Africa, much of Africa generally,
much of the Caribbean, Ireland, Malaysia, Indonesia, Singapore etc etc if you
don't like the way we do it.

How about you really go metric?

Name the non-metric measurements still in official use in the UK.

I never suggested it as a replacement for the electric car. The
question was about how to do a hybrid system. In a hybrid, the total
amount of energy to store is much less but the number of cycles is
huge.
