Re: Hybrid cars
That study may have been tainted to show that fossil fuel is more
appropriate than natural fuels.
I'm not speaking of supplying a city's power.
That can be done the old fashioned way with water and turbines.
Alochol fuel is replenishable and therfor there would be abundance of
fuel for vehicles for as long as there is farm land to produce the raw
products.
If fossil fuel is such a big deal, why don't we have cars that get
100mpg?
The technology for doing so is here and has been here since the 60's.
The auto manufacturers do not want YOU to have such a vehicle because
that would mean selling less fuel.
There is also current technology on the road, in experimental form,
that is showing how viable fuel cells are.
One company is testing a hydrogen/oxygen fuel cell.
To replenish your supply of hydrogen, you simply pull up to the pump
and insert the nozzle same as you do now with gas.
The hydrogen is created from water, which is housed in a container at
the pumping site.
As a benefit to the atmosphere, your by-product is water.
There are alternatives to fossil fuel.
Way back in the mid 60's we were told we would be out of fossil fuel by
1990.
In the 70's we were told there would be no more in 2000.
It all boils down to whom you want to believe in.
And when all else fails, create your own fuels.

Not really. It is because horsepower is directly related to energy content
of the fuel, and you cannot have high powered guzzlers and still get 100
mpg.

We aren't going to run out completely, at least not yet. But are you
ready to pay $15-20 per gallon that it WILL cost, if it is even available,
when the supply actually is lower than the global demand.
There is NO light on the horizon. It is a matter of when, not if.

It's not so much the horsepower, but the weight, gearing, and aerodynamics
(or lack therof) that are inherent in truck-based SUV designs. The LS2
engine (400 HP) from GM gets over 25 MPG in a car. A buddy of mine has a
Dodge Durango with a 318 V8, I think it puts out about 220 HP, and gets
around 15 MPG.

Like I pointed out, horsepower is not the main culprit. I drive a Cavalier
with a 2.2 liter 4 cylinder engine pumping out a whopping 115 horsepower. I
get around 30 MPG on the highway. I know a guy with a mid-90s Chevy Caprice
with a 5.0 liter V8 and he gets almost as good as I get.
Another culprit is the automatic transmission. I would probably get around
35-40 MPG if my car had a manual.

I have a FI 318 that gets me 17-18 mpg. But horsepower IS an issue. You
cannot get horsepower without burning fuel. You can optimize mileage by
not developing full advertised horsepower at the operating speed. I've done
the math. There is no free lunch.
Weight, gearing and aerodynamics are clearly issues as well.

Yes, you pointed it out, but are not quite correct. To get excellent
mileage you
have to drop actual horsepower, decrease weight, improve aerodynamics, etc.
The automatic transmission, which USED to be recognized as a mileage culprit
is not that any longer. An automatic, properly set up and functioning, can
deliver better mileage than you can get with a similarly geared standard.

Look at how many highly promoted hybrids there are, and their real
world (not EPa) economy figures. Then look at small european diesels
and their real world MPg figures. see what the difference is.

How so? An automatic uses a viscous coupling, and there is always going to
be slippage. Some slushboxes have lock-up torque converters, which help
mileage in top gear, but the tranny still slips during acceleration.

Regarding horsepower, the mathematics follows:
1 horsepower is equivalent to 0.7457 kilojoules per second
gasoline typically delivers 50 kilojoules per gram
Now, if a car is REALLY delivering 300 hp, that would mean without
loss corrections, that you would be burning about 224 kilojoules per
second of fuel, or about 4.5 grams of gasoline every second.
In an hour, you would be burning over 16000 grams of fuel to maintain
that horsepower, or about 35 pounds of fuel. That is approaching 5
gallons per hour. If you are doing 70 mph over that hour, then you cannot
get more than 14 mpg theoretical maximum.
We both know that high advertised horsepower cars might get that good
or even a little better, so what that tells us is that the engine
maintenance
systems, transmission, etc, limits the horsepower during this period. We
are
actually NOT generating 300 hp, at least not all the time.
So the bottom line is that horsepower -actual horsepower - costs.
It is inevitable. To decrease the fuel consumption, actual horsepower
generated
has to be decreased...And that can be done with weight control, rolling
friction
(tires), aerodynamics, tranny and its electronic controls, engine controls,
air condition
usage, electricity usage, etc.
Now, assuming your 100 mpg situation, and again assuming you run 70 mph
over the test period, you could not be allowed to average more that 0.7
gallons
consumption over that hour. That is very roughly 4.9 pounds of fuel, or
2225
grams. This equates to about 40 well managed horsepower...
See the discrepancy?

Maybe you had better take a look at current autos. ALL of them have
lockup converters and 99% have overdrive as well. They are MUCH better
than a stick for mileage now.

You might like to look at the EPA test results. Cars with manual
transmissions get something like 1 mpg better mileage than the same car
with an automatic:

There is great debate about the value of alcohol fuels. Studies by a
professor at Cornell University suggest that it takes more energy to
grow the corn (fertilizer, plowing, harvesting, etc.) and distill the
alcohol than you get out of the alcohol itself. Therefore, you really
don't gain anything that would displace fossil fuels.

They can't make 100 percent into 2 percent by some slight adjustments in
facts. The reality is that alcohol is not much of an answer to the
problem with a shortage of fossil fuels.
