Why do we need algae diesel as a plan A, when there are
centuries worth of synthetic crude to processed from coal?

We know oil from coal will work, and that will allow
us to stay wealthy enough to fund the research to get
fuelcells and/or advanced batteries up and running.

Dont need to do any research, as you say the coal will last for
centurys and we can use hydrogen from nukes when that peaks.
What nukes?
Hydrogen is ALREADY being used as a transport fuel.

Post peak: Extra labor suddenly becomes cost effective.
Without tractors most everyone will starve.

Human labor isn't an option. If it were, Africa wouldn't be

I believe the author's philosophy is that you operate the
tractor say for a half hour and then spend 5 minutes re-charging
the battery---and that the cost of the tractor operator's
labor spent re-charging batteries is less than the additional cost
you would use with the higher priced fuel (diesel vs electricity).
The author has no farming experience. How is he going to recharge
those batteries? There isn't any power outlet in the middle of
1000 acres. Run power lines? Then a plow can't plow the soil and
a combine can't harvest. Going around things is not a nice thing
to have to do when farming fields.
All real world problems are trivial to the arm chair, hand waver who
has never done any real work nor paid the bill for their own ideas.

I'd spent a year in this newsgroup when I decided that one solution to the abject stupidity was to have all kids spend
2 years working on a farm.

Thats what Cambodia and China tried. No thanks, comrade.


Farmers are experts in applied physics. You need a good dose

I keep hearing that phrase, "clean electric drive". Electricity is not
clean.

But A LOT cleaner than gasoline and diesel burned in ICEs ?
And it we ramp up electric power from renewables, and phase out coal, then it gets even a lot better.
Coal will never be phased out in any foreseeable future.
Go work in a wire manufacturing factory for a while.

I actually did. Worked in a high-voltage cable manufacturing plant in the Netherlands
for a while. It was pretty clean there :eek:)
Then you didn't manufacture the components. did the company buy the
wire spools?


What are you trying to say ?
There is no such thing as clean energy. There is also no such thing
as free energy.

Every hare-brained idea in this newsgroup is based on the goal of
producing energy for all demands forever at no cost and no

Funny, I posted about how that 3X-4X efficiency was just plain false,
because even farm diesels can feasibly be built to 50% efficiency and
there has to be a conversion loss from whatever it was that generated
the electricity. Unlike Otto cycle ICE's, the part-load efficiency of
a diesel is also rather high. As they are always run at wide open
throttle, even idling is not overly consumptive of fuel( truckers
stopped idling their engines to stop polluting, not to save money
[although they now do that, too]).

The biggest advantage of electrics is not efficiency, but combining
all of the polluting where economies of scale lessen the costs of
pollution control/ CO2 sequestration.

And eliminating CO2 completely by using nukes to generate the electricity.

Not a shred of rocket science whatever required.

i suspect speed. Remember also that oxen tended to come in one overall,

Could have also been the preference for the area, e.g almosat all

There is little cause and effect here. The price is down because it was a

__**I THINK**__. But I admit it is a guess based on the Congress not

This is not true.

Electric drive is 4X more efficient (not even counting regenerative braking), zero-pollution at the tailpipe (it has none), and is
much lighter than an ICE.

Only if the electricity magically comes from somewhere free, and you
lug enough batteries for 20 miles of travel.

But the electricity sas to be generated somewhere, at thermal
efficiency levels. Transport, chargers, and batteries throw a bunch of
it away. Batteries are heavy and full of nasty chemicals.




More expensive ? Prototypes are always more expensive.
But let's see :

ICE : Complicated engine with lots of rotating and moving parts, with oil + water cooling system, with emission control (incl
catalytic converter with precious metals), with transmission and a differential and exhaust system and a massive amount of pipes
and sensors.

And it all works great. I can load up 200 HP-hours worth of energy in
about 2 minutes at a gas pump. That's about a 5 megawatt equivalent
charging rate. And I can drive coast-to-coast on about an hour of pit
stops.

You seem to confuse electric drive with EVs.
Electric drive with a small auxiliry power unit will give you all the benefits of the current gasoline (or another fuel)
infrastructure.
Like in the Volt (the only model with electric drive that GM actually has a plan for)....

Stuff like this has been "planned" for decades. I'll be impressed whan
quantities of them are on the road.

A plug-in hybrid does make sense for city drivers. But small, light
cars make sense no matter what propels them. A small, light
gasoline-powered car may make the most sense.
The external costs of the fuel do not appear in the price. And if these
costs were part of the price then biofuels would be the best current
alternative. This is true here in the USA because we actually have the
land necessary to produce that fuel and it is land that is not currently
serving any good purpose or land that is serving a purpose that is not as
environmentally and economically valid as it would be if devoted to fuel
production. An example of this latter case is the production of paper
that ends up in the land fills as trash. We could do with a bit less
paper and use the pulp trees to make fuel. That is probably a good trade.

Sometimes I get into my Rabbit in the morning, start it up, drive away
5 seconds later, turn on the radio and the heater, ignore the steep
hills and the cold rain, and marvel at the whole process. And that
hundreds of millions of other working people can afford to do the same
thing.

Yes. me too.
The ICE has served us greatly over the past 100 years that oil was abundant and cheap, and the engineering advances made are
magnificent.
The ICE also enabled an astounding economic growth that we (as the people of this planet) have created for ourselves.
It also created a number of really big problems, which start to become apparent, increasingly difficult and pressing as well as more
and more expensive.
More expensive for individuals, as well as nations, as well as the planet's eco systems.
It's time for change (before another 2 billion people join in our lifestyle).



Electric drive : a few melon-size electric motor/generators and a power control unit.
Add a small (40hp) auxiliry power unit and you drive a 80mpg vehicle.

Mmmm. What would be cheaper in mass production ?

What *is* cheaper?

Want to bet ?
In mass production, I want to bet that electric drive is significantly cheaper to produce than ICEs.

If electric cars are cheaper and more efficient,
why aren't they popular? Conspiracy?

John, I don't believe in conspiracies. In a free market the most cost efficient solution wins. But big changes take time.
The incentives are there now (to start moving to electric drive, away from oil and towards electricity), but only for the last
couple of years.
Also the political will to change (to start moving away from oil and fossil fuels) has not been there.
We are just getting started (with PHEVs).
This process is going to take a while (to move vehicles away from oil and towards electricity).
15-20 years is my estimate.
And biofuels are a big part of that which fills the gap.

Batteries cost ?
If you are an average American, you spend around $3,000/year in gasoline right now.
I bet that for $3,000/year you can lease a top-of-the-line battery pack. Even at current low-volume prices.

What is cheaper ?
What is cleaner ?
What is more efficient ?
What is better prepared for the post Peak-Oil era that we just entered ?

The peak oil point is always 10 years away.

That is impossible.
Oil will peak at some point if it did not already.


Hey, build yourself an electric car and save a bundle. There are lots
of conversion kits on the market.

I might just do that, although retrofits are very seldom cost-effective.
I pretty much have to throw away half the vehicle (ICE/drivetrain etc etc you know it).
And the other half (chassis) got crumbled on I 238 last week :eek:(


There just aren't any good batteries.

After all we talked about, this is what you say ?
It seems to me that you have made up your mind on this subject.

Where's the great battery? I suspect a really good auto battery may be
impossible.
Biodiesel is one super duper battery. The shelf life is really good and
the weight is not all that bad for the energy content. The photosynthesis
is a the way you charge the battery. We need better algae that can get
20% efficiency as opposed to 8%. There was some promising research on
this and some folks observing less than 8 photons to cause proper
reactions and then .... nothing. There were some dudes shifting light
wavelengths from blue to yellow red and that seems to have gone also.
Nothing is happening that I can find.

How do I search (like google) the patent data to find stuff like this?

Dear The Trucker: The 'up-side' of paper is that it comes from trees
that also "eat" CO2. My bio-mass of choice is hemp. Such removes
several times more CO2 per acre than does a forest. The best
immediate correction of our auto emissions problems is to use
optimized engine RPMs and loads to generate electricity for driving
the vehicle. Having engines run at varying speeds is hugely
inefficient.
There are fixes for the symptoms of global warming which can buy
time to develop fuel alternatives. Battery technology that uses toxic
metals isn't environmentally friendly. One very environmentally
efficient solution is to make higher quality, longer lasting
vehicles. The energy being used to make "the latest" model is adding
nearly as much CO2 to the air as the fuels we burn. "Less is more.",
but isn't necessarily a bad way to be living! — NoEinstein —

An ox is a steer (castrated bull) allowed to live to full growth.
Meat steers are slaughtered while still young and tender and stud
bulls are culled shortly after the onset of sexual maturity and
collection of marketable amounts of sperm. Other than the fact that
oxen are allowed to live as long as dairy cows, there is nothing to
seperate them normal cattle.

They are slower than horses, but their shoulder hump makes them
anatomically better suited to pulling, and they do have longer
endurance. They were rendered obsolete for general farm work by the
horse collar, which solved the problem of strangling horses, as horses
could also be ridden and pull carts at faster than a walking pace.
 
Peak Oil and the continuation of high oil prices until we use less of it creates all kind on new business opportunities.

People keep finding more oil. And the price is down lately, $113
today.
Looks like a good time to buy lot of those undervalued SUVs!

You'll make a killing when the price drops to $2.50/gallon!

There are just an amazing amount of new battery possibilities when vehicles
finally move away from the inefficient, polluting, and heavy ICEs, and
towards an era of clean electric drive.

Except that everything else, so far, is less efficient, more
polluting, and heavier. Not to mention way more expensive.

This is not true.

Electric drive is 4X more efficient (not even counting regenerative braking), zero-pollution at the tailpipe (it has none), and is
much lighter than an ICE.

Only if the electricity magically comes from somewhere free, and you
lug enough batteries for 20 miles of travel.

But the electricity sas to be generated somewhere, at thermal
efficiency levels. Transport, chargers, and batteries throw a bunch of
it away. Batteries are heavy and full of nasty chemicals.

More expensive ? Prototypes are always more expensive.
But let's see :

ICE : Complicated engine with lots of rotating and moving parts, with oil + water cooling system, with emission control (incl
catalytic converter with precious metals), with transmission  and a differential and exhaust system and a massive amount of pipes
and sensors.

And it all works great. I can load up 200 HP-hours worth of energy in
about 2 minutes at a gas pump. That's about a 5 megawatt equivalent
charging rate. And I can drive coast-to-coast on about an hour of pit
stops.

You seem to confuse electric drive with EVs.
Electric drive with a small auxiliry power unit will give you all the benefits of the current gasoline (or another fuel)
infrastructure.
Like in the Volt (the only model with electric drive that GM actually has a plan for)....

Stuff like this has been "planned" for decades. I'll be impressed whan
quantities of them are on the road.

A plug-in hybrid does make sense for city drivers. But small, light
cars make sense no matter what propels them. A small, light
gasoline-powered car may make the most sense.

The external costs of the fuel do not appear in the price.  And if these
costs were part of the price then biofuels would be the best current
alternative.  This is true here in the USA because we actually have the
land necessary to produce that fuel and it is land that is not currently
serving any good purpose or land that is serving a purpose that is not as
environmentally and economically valid as it would be if devoted to fuel
production.  An example of this latter case is the production of paper
that ends up in the land fills as trash.  We could do with a bit less
paper and use the pulp trees to make fuel. That is probably a good trade.







Sometimes I get into my Rabbit in the morning, start it up, drive away
5 seconds later, turn on the radio and the heater, ignore the steep
hills and the cold rain, and marvel at the whole process. And that
hundreds of millions of other working people can afford to do the same
thing.

Yes. me too.
The ICE has served us greatly over the past 100 years that oil was abundant and cheap, and the engineering advances made are
magnificent.
The ICE also enabled an astounding economic growth that we (as the people of this planet) have created for ourselves.
It also created a number of really big problems, which start to become apparent, increasingly difficult and pressing as well as more
and more expensive.
More expensive for individuals, as well as nations, as well as the planet's eco systems.
It's time for change (before another 2 billion people join in our lifestyle).

Electric drive : a few melon-size electric motor/generators and a power control unit.
Add a small (40hp) auxiliry power unit and you drive a 80mpg vehicle.

Mmmm. What would be cheaper in mass production ?

What *is* cheaper?

Want to bet ?
In mass production, I want to bet that electric drive is significantly cheaper to produce than ICEs.

If electric cars are cheaper and more efficient,
why aren't they popular? Conspiracy?

John, I don't believe in conspiracies. In a free market the most cost efficient solution wins. But big changes take time.
The incentives are there now (to start moving to electric drive, away from oil and towards electricity), but only for the last
couple of years.
Also the political will to change (to start moving away from oil and fossil fuels) has not been there.
We are just getting started (with PHEVs).
This process is going to take a while (to move vehicles away from oil and towards electricity).
15-20 years is my estimate.

And biofuels are a big part of that which fills the gap.







Batteries cost ?
If you are an average American, you spend around $3,000/year in gasoline right now.
I bet that for $3,000/year you can lease a top-of-the-line battery pack. Even at current low-volume prices.

What is cheaper ?
What is cleaner ?
What is more efficient ?
What is better prepared for the post Peak-Oil era that we just entered ?

The peak oil point is always 10 years away.

That is impossible.
Oil will peak at some point if it did not already.

Hey, build yourself an electric car and save a bundle. There are lots
of conversion kits on the market.

I might just do that, although retrofits are very seldom cost-effective.
I pretty much have to throw away half the vehicle (ICE/drivetrain etc etc you know it).
And the other half (chassis) got crumbled on I 238 last week  :eek:(

There just aren't any good batteries.

After all we talked about, this is what you say ?
It seems to me that you have made up your mind on this subject.

Where's the great battery? I suspect a really good auto battery may be
impossible.

Biodiesel is one super duper battery.  The shelf life is really good and
the weight is not all that bad for the energy content.  The photosynthesis
is a the way you charge the battery.  We need better algae that can get
20% efficiency as opposed to 8%.  There was some promising research on
this and some folks observing less than 8 photons to cause proper
reactions and then ....  nothing.  There were some dudes shifting light
wavelengths from blue to yellow red and that seems to have gone also.
Nothing is happening that I can find.

How do I search (like google) the patent data to find stuff like this?

Dear The Trucker: The 'up-side' of paper is that it comes from trees
that also "eat" CO2.
You seem to misunderstand the word "trade". The trees still grow and eat
the CO2 as before. But instead of making paper we use the wood to make
cellulosic ethanol.

My bio-mass of choice is hemp. Such removes
several times more CO2 per acre than does a forest.
People always want to do hemp because it is controversial. I figgure you
for a leftie.

The best
immediate correction of our auto emissions problems is to use
optimized engine RPMs and loads to generate electricity for driving
the vehicle.
Nope. Biofuels fit into the current fleet of cars and allow the new fleet
of hybrids to come on line in due course.

Having engines run at varying speeds is hugely
inefficient.
There are fixes for the symptoms of global warming which can buy
time to develop fuel alternatives.
Yes... I have tried to name several of them and they are all currently
ready to roll biofuels that need a decent government initiative as opposed
to oil company Republican fascism.

Battery technology that uses toxic
metals isn't environmentally friendly. One very environmentally
efficient solution is to make higher quality, longer lasting
vehicles. The energy being used to make "the latest" model is adding
nearly as much CO2 to the air as the fuels we burn. "Less is more.",
but isn't necessarily a bad way to be living! -- NoEinstein --
The latest model should be a hybrid.
