Hybrids - Toyota vs Honda

Thank you very much for your informative reply.

 

Sorry, they're for light aircraft in the UK too.

Documents and reports should be available at your local HSE office, go
n and ask nicely. They should be able to find you the mountains of
reports on it.

 

Torque X rotational speed = Power. To get the units right in various
systems, a conversion factor is used.

A very good discussion is available on the web at:

http://www.straightdope.com/mailbag/mhorsepower.html

Power is the ability to do work. Work is needed to move a mass from one
place to another, to increase elevation, to increase velocity
(acceleration) and to overcome frictional losses like air resistance,
tire rolling resitance, etc.

Thus, for example, 200 ft. lbs. of torque at 4,000 RPM can accomplish
twice as much work as can 200 ft. lbs. of torque at 2,000 RPM. Put
another way, 400 ft. lbs. at 1,000 RPM can do the same work as does 200
ft. lbs at 2,000 RPM. For the units used in the US:

Power (HP) = [Engine Speed (RPM) x Engine Torque (ft.lbs.)] / 5252

It is really that simple.

2006 is certain to take away a lot of the thunder from Mr. Hunter's
argument. Large truck and SUV sales are dropping like a rock while
sedan and small crossover SUV sales are increasing.

Somewhere in the next couple of years Toyota is going to pass GM in
worldwide sales volume and will never look back. If the Delphi
bankructcy results in supply distruptions to GM, which is highly likely,
then 2006 will be the year of the changing of leadership for sure.

Years ago GM unseated Ford and has never looked back. GM did it with a
better product range and agressive salesmanship. Unfortunately Detroit
has had it's eye off the ball for too many years now.

An excellent point you make sir! Wind power to add to energy storage,
be that storage hydrogen or some form of battery, makes lots of sense.
It is much harder to make wind generators put out the constant voltage,
constant phase output the grid wants to see.

John

 

Indeed. Before electric power and motors became ubiquitous, windmills
were commonly used to pump water out of wells for farms and ranches.
Their unpredictability and relatively high maintenance and repair
requirements compared to electric pumps all but eliminated wind power
from it's historic water pumping roll.

How did you arrive at that conclusion? The ONLY vehicle in the top five to
drop in sales was the Camry, all the others have gone up. Trucks and SUVs
still account for half of all sales combined and there are a lot more car
models than light truck models on the market. Perhaps you meant to say in
my opinion?

Part of the reason the 3 pickups (they are not trucks-a dumptruck is a
truck, an 18-wheeler is a truck) made it to the top 3 is because Chrysler,
Ford & GM used the lure of "employee discount" to pad the sales. Honda and
Toyota used their normal discounts for this time of year. GM lost over a
billion in the last quarter. Analysts say both GM and Ford will be out of
business by 2015. The only sales they will get are the typical "must buy
American" sheep.

 

I own a pickup and a minivan, and I notice that pickups always fall behind
on grades because of their poor wind resistance. It is why hybrid technology
is wasted on pickups and SUVs for MPG and why huge engines are wasted on
them also. You can push a billboard through the wind only so fast. It seems
like the fastest drivers on highways have Accords and Jettas.

 

Once again you are confused. The sales figures are for the F150 & F250, the
Silverado and the Ram trucks for sizes up to 8,500 GVWR. IF all light
trucks were include, the total figures would be even higher.

Trucks over 8,500 like the F250HD and the F350 are not counted in the
individual sales figures. Light trucks like the current leaders has nothing
to do with discounts, light trucks have been outselling cars since 1975 when
the majority of car went to FWD. The Ford F150 is by far the best selling
vehicle had has been for nearly thirty years. When SUVs are included light
truck sales have exceed car sales for several years.

Perhaps you might want to do some research before commenting further on a
subject of which you apparently have little or no knowledge, or at least say
in my opinion.

Now this isn't to dismiss you totally - I'm sure there are some
stupid or poor eyesight species of birds where the airplane visibility
balls are a help, especially where the wires pass several hundred
meters over a valley where they would expect to find clear air. But
they were placed there primarily for airplanes.

But if the birds are there at that altitude too, that raises the
problems of bird strikes on airplanes...

And when a Raptor (hawks, falcons, etc.) is following a pigeon and
has his mind solely on Dinner!, he's going to follow the prey bird
till one of them loses the chase. And a smart prey bird is gong to
try to lose the predator however they can - and leading him right into
the blades of a wind turbine, or the side of a building, or a cliff,
is a great way to lose your pursuer. Permanently if possible, so they
don't have to go through this whole chase scene all over again
tomorrow.

Raptors like to light on top of power poles and zap themselves
between the lines, too. Which led to them putting a bare crossarm at
the top of certain favorite poles with no wires, solely to act as a
perch. The transmission lines are on the next crossarm down.

But it's not done for the birds, it's for practical reasons - a bird
gets zapped, and the flash-over trips the circuit breaker for that
transmission line and shuts that line off for anywhere from a few
minutes to a few hours.

 

Reminds me of a story my grandfather told me, of the early days
of coal mines in the north of England.

It seems one mine used to generate 10,000 volts to run its gear,
but did so several miles from the pit, which involved setting up
power lines across open countryside... Okay, you've guessed the
punchline; but ride with me for the scenery.

Now and then power would fail at the pit. A man would be sent to
walk the lines. He never seemed to find a cause. When breakers
were closed again, the system would run fine -- until next time.

One day someone was out on the moors (or whatever) and noticed a
group of rooks (or similar gregarious, prone-to-squabbling birds)
had roosted on the lines. As he watched he saw a rook, on one
line, lean across to peck at a neighbour, on the other line--

The explanation for the failures came, as it were, in a flash.

(Okay, stupid line layout. Early days of HT power transmission.)

 

Why? Do you qualify YOUR lame, unsubstantiated opinions with "in my
opinion?"

So the top two passenger cars are Toyota and Honda? Conclusion: people
like them more than they like Fords, Chevys and Pontiacs. Maybe they think
they're a better value. Maybe they hate wasting money on gas and would
rather get a car that gets good gas mileage than one that gets mediocre gas
mileage.

Gee... Maybe Detroit should think about that.

By the way, I notice you didn't provide a reference. We're supposed to
believe your figures?

 

Synergy beats Honda.

 

Yea. Gotta love those offset crash test videos! Total it, and if you
survive, buy another!

 

Why don't you **** off back to your Ford ng?

 

and of course, common sense might also dictate that if they can't see
the line without the balls, they can't see it WITH the balls, and just
see the balls, and are as likely to go to either side as up. I don't
recall seeing anywhere that someone has taught birds 'when you see the
balls, there's powerlines and you got to go up over them' They don't
know what the balls mean, just that they're balls.

yep, happens a fair bit, mainly with deaf birds, who don't hear the
aircraft - noise plays a bit part of birds lives.

Think we established elsewhere 9certainly on one of my emergency
services groups) that the line breakers nowadays reset themselves 3-4
times, before breaking perminantly, just for that reason. Seen plenty
of warning notifications that say 'even if the hot stick says the
lines off, don't assume it is, because of the breakers. Wait for grid
controller confirmation before entering the vicinity of the jump-zone'

 

That's funny. Some guys in the Ford NG tell me to go back to the GM NG when
I point out GM outsells Ford. Some guys Honda NG tell me to go back to the
Toyota NG when I point out Toyota outsells Honda They don't like to be
presented with facts that disputes their personal biases and opinions either
it seems

Again you are confused I don't present opinions, what I posted are fact that
are available to anybody willing to do the search. Although Toyota and
Honda have the number one and two selling individual model cars, and Ford
has the best selling individual truck GM sell more cars than Ford, Toyota
and Honda as well as more trucks than Ford, Toyota and Honda . As to fuel
mileage GM offers far more vehicles that get over 30 MPG than does Toyota.
GM even offers a full sized V8 Chevrolet that gets nearly 30 MPG. Better
do some research if you are going to continue to post on this subject

Such as, ohhh, with a CVT? Had a few of them over the years, kinda
weird sitting there, accelerating, and getting NO change in the engine
note, as it holds at its peak torque point, Good old rubber band cars,
much more efficient than regular slushboxes too, since they dont have
so many nasty planetaries.
