The 2001-2003 Prius is remarkably nimble and manueverable, the features I
prized in the Lotus and sorely missed in the Nissan 300ZX. Dunno about the
current version. I despise automatic transmissions, so I had reservations
about the "ECVT" of the Toyota Hybrid System. Boy, was I surprised! The
accelerator calls up power with supernatural smoothness and predictability.
I hate the way automatics always seem to be in the wrong gear or downshift
when I didn't want them to - never an issue with the THS. I drove it once
and fell in love.
People are always stereotyping me and ascribing motives according to their
preconceptions when they find I not only own a Prius, I love it. I am not a
liberal, I am a Reagan Republican. I am also a minor motorhead (I have a
brother who is a major motorhead, so I know the difference!) I know what I
like, and this is it. Now when I have to drive a conventional vehicle,
especially one with an automatic tranny, I wonder, "what is all the
'vroom-clunk, vroom-clunk' about?" The irony is that now my wife has it and
I have her Volvo wagon with an automatic... vroom-clunk. :-(

The vehicle would have to be absolutely huge to be going only 70mph at
300hp. Even a fully loaded semi would probably be doing over 100mph
at that power setting.

Actually, given the 33% efficiency factor, the engine would only be
delivering about 13 hp. Only a very small car could achieve that. To
give you an idea how small, consider that a go-cart with a 9.5 hp
engine tops out at about 50 mph. With 13 hp it might get up to 65.
Your 100mpg car will have to be to be smaller and/or more aerodynamic
than that.
Theoretically, it doesn't matter how much power the engine can
generate, it only matters how much you use. In reality, there is
added inefficiency running the engine at low power settings and more
powerful engines are likely to burn more fuel at idle when you are
getting 0 mpg. For those reasons, a more powerful engine will consume
more fuel even if it is not driven any faster that the same car with a
less powerful engine. In practice, drivers tend to use the power they
have available, so the difference is even greater.

Definitely true. Water storage is a proven and attractive way to use
intermittent generation to provide power on demand, competitive with current
peaking sources. The problem is that the intermittent power producers
haven't seen fit to do that in the US AFAIK.

No, it is more efficient when working harder, at least up to ~70%
power. Unless it is very underpowered or the hill is very steep, it
won't be working that hard.

Of course, that expensive spot market can be supplied by unsold wind
power.
Admittedly, the somewhat unpredictable nature of wind power is a
limitation, but the system already has to deal with uncertainty. How
can you buy power for next July if you don't know whether it will be
record breaking hot or record breaking cold? Yet the only time we
have ever seen it (the power brokering system) fail was when the
crooks at Enron were doing Grandma Millie. If the system survived
that, it shouldn't have any problem figuring out how to deal with a
20% mix of wind power (if that is even achievable.) If the
deregulated private market can't figure it out, there are
alternatives.

The problem with business sense is that it only makes sense when you
consider that profit/personal greed is the only success criteria.
That is why the rules of the game have to be set and enforced so
carefully. The Enron California debacle pointed out what happens when
the rules (or lack thereof) fail. The California players all knew
that Enron was cheating, but they had no choice but to keep playing
the game with a man who had a hundred aces up his sleeve. If someone
had just pulled out a gun and shot Ken Lay after the first cheat,
California would be a few billion dollars richer now.
Sometimes, the only way to set up a game that is fair and efficient is
to let the government play a bigger role.

Of course, that expensive spot market can be supplied by unsold wind
power.
Admittedly, the somewhat unpredictable nature of wind power is a
limitation, but the system already has to deal with uncertainty. How
can you buy power for next July if you don't know whether it will be
record breaking hot or record breaking cold? Yet the only time we
have ever seen it (the power brokering system) fail was when the
crooks at Enron were doing Grandma Millie. If the system survived
that, it shouldn't have any problem figuring out how to deal with a
20% mix of wind power (if that is even achievable.) If the
deregulated private market can't figure it out, there are
alternatives.

The problem with business sense is that it only makes sense when you
consider that profit/personal greed is the only success criteria.
That is why the rules of the game have to be set and enforced so
carefully. The Enron California debacle pointed out what happens when
the rules (or lack thereof) fail. The California players all knew
that Enron was cheating, but they had no choice but to keep playing
the game with a man who had a hundred aces up his sleeve. If someone
had just pulled out a gun and shot Ken Lay after the first cheat,
California would be a few billion dollars richer now.
Sometimes, the only way to set up a game that is fair and efficient is
to let the government play a bigger role.

Unfortunately, not to any great extent. The problem is that contracts for
peaking are usually made the previous day, on an hourly basis. The market is
competitive to the point of being cutthroat, and the closer the time gets to
the delivery time the higher the prices are; cheap power has already been
bought. That is the problem with intermittent generation - how much can you
produce between 1400 and 1500 hours tomorrow? How much can you produce in
the coming hour, with much higher penalties if you can't? Allow too much for
the vagaries of nature and there is no point being in business. Allow too
little and the penalties will cost far more than you could ever make. Don't
agree to the penalties and nobody will buy at any price.
The proposed FERC rules are intended to reduce the effect of impending
delivery, so intermittent generators can compete with the peakers as close
as an hour to delivery time. That will necessarily drive the spot market
through the roof as peaking producers try to make a living, but that's the
tradeoff. In exchange, intermittent producers would have to become good
citizens on the grid, doing their part to correct voltage sags and high VARs
(bad phase angles.)
Personally, I don't understand why the intermittent producers don't invest
in water storage. The high up-front cost can be recovered at a more
predictable rate than the cost of the generation equipment can.

Has anyone attempted to determine the results of windmill farms?
Science tells us that to create energy from the wind, we take that
power out of the wind. If we intercept this force enough, what changes
are we imposing on nature?
Not saying we *shouldn't*, but we've already gone way down the
destructive road with other sources, maybe we need to do some research
before figuring that wind-generated power is "free"....

This is ridiculous.
The useable part of the atmosphere goes up to about 36,000 feet. How
tall is a wind generator again?
Are you changing the earth's climate by putting a few *wind farms*
down on the ground here and there? I don't think so. Your fear is
groundless ( that is a pun ).
It is like saying you're going to change the ocean currents if you put
the Queen Elizabeth or some other Ocean Liner to Sea. Yah, a little
bit. But not enough to detect.
