I'm not referring to the concept of grease rustling, I'm referring to the supposed ills of running hot grease. Go back and read his post. All kinds of inaccurate info on the affects of veggie oil in a diesel.
It is not that it can't be done. It is that it doesn't have a meaningful impact on present demand.
Like putting a band aid on a severed artery.
Best, Dan.
Price of coal has doubled in the past year.
Thanks for the informative post.
Best, Dan.
Reminds me back to when I had a store front in a small town. The occasional survivalist would come in and talk about living off the land. Hunting deer. I would think to myself. "You and several dozen hunters per acre chasing the same scrawny deer..."
You don't seem to get it. You seem to think you are going to do so much better than others as the demand for oil outstrips the ability to produce. This makes you the wealthy guy on the block.
Wealth inequity requires enforcement. Always has, always will.
Best, Dan.
What comment did P.T. Barnum make about that? Or are you referring to the comment David Hannum made of Barnum's customers?

The price of tends to follow across the various forms. That isn't the same as saying they're equivalent, but it does relate to a basic truth that price pressure on one tends to drive flexible demand to other forms. U, of course, being the most inflexible by far, is much less affected, particularly in the near/mid term.
Here's one quote found quickly...
An Analysis of Steaming Coal Price Trends--Factors behind Price Fluctuations and Outlook, Yoshimitsu MIMUROTO, Group Manager, Coal Research Group, International Cooperation Department
"While many factors are considered interwoven in these price fluctuations, more responsible ones than others are verified in this report. They include (1) exchange rates of the Australian dollar, (2) fluctuations in coal stocks (degree of supply and demand tightness), (3) coal productivity (production cost), (4) the U.S. coal ex-port trends, and (5) the price of oil as a rivaling fuel."
As will the effect on US coal prices.
I did find one report in London that so far, the effect hasn't shown up owing to current inventories but it did note that diesel prices are going to affect production costs in the near future. There certainly is going to be an impact on margins which are minimal at best and the trend in the past has been to shut down production when not making money at the mine mouth. If so, stockpiles will eventually become depleted and price will eventually rise. Question is (which I don't presently know having quit working actively about five years ago now) whether there's sufficient stockpiles to weather the short term blip(?) owing to Katrina w/ winter coming on. W/ the tendency of major utilities like TVA to shorten their stockpiles to help in cash flow, I would doubt their ability to do that to any great extent.
Consequently, I still expect to see an impact on coal prices.
I suppose the one possible mitigating factor in all this will end up being China. If the higher oil prices hold and impact US (in particular, rest of developed world to a lesser extent) consumer spending it could lead to a reduction in demand there as well. In that instance much of the current pressure on oil markets could be temporarily relieved.
Typical, perhaps, but not 100% of all agrements are like yours are they?
Assuming he is scavenging, how can you make the statements above? How can you accuse him of receiving stolen property when you don't have a clue what agreements he may or may not have? I'm amazed at how you have intimate knowledge of someone else's sources of oil.
From a website called green-trust.org?
Sure. Of course the FEDEX charges will be more than the ribs..... Did you know that dry ice is now "hazmat" for shipping purposes?

The word is "effects", Steve, "Effects".
OK, Steve, as a retired engineer with much experience in the automotive field and who still occasionally consults to one of the Big Two, I have an open mind. Convince me that you've objectively addressed the potential problems I wrote about.
Tell me about your lab analysis that proves that your veggie fuel contains no pumice, silica fines or silicone oil. Convince me that you were even aware of those issues before my article.
Show me the data from your extended durability testing on even one current production engine. It is normal for OEMs to run a fleet of diesel engines through 100,000 hour durability runs when changes in fuel are being evaluated. Things like lowering the sulfur level. Show me the tribology data comparing your oil to the API and SAE standards for diesel fuel. Ford, for example, has over 250 dyno cells under one roof in Dearborn just to run these kinds of tests. What do you have?
Don't have any of that? Then on what basis do you claim that the concerns that I raise are wrong? I can certainly tell you what some of the guys who design the engines and injectors and who DO have the data say when I've asked. "Not in my damned truck!". Yeah, I know, bought and paid for by the auto-oil axis, right?
While you're at it, tell me about your liability insurance that will make your customers whole in the event your fuel causes premature wear or other damage.
Don't have any of that? No surprise there either.

Well damn, Dan, if I have a geothermal spring in my back yard I won't have rollover either. Few people have access to ground water so why even bring it up? As in many places, it's against local ordinances to drill a well inside the city limits so even if people have the land, city dwellers can't use the water under it.
Drop that COP down to maybe 1.5 for a high efficiency air exchange heatpump operating in an ambient in the 30s and you'll be much closer to reality. Not much better than 1.1 for older units.
Electricity might still win out in some areas but one won't know using garbage numbers.
To address another commentator in this thread, no, I don't have to evaluate the 20 year cost of a heat pump to determine its payback. If I have multiple sources of heat, I can choose the cheapest for any given time period. A high efficiency heat pump is probably going to be the winner in moderate conditions during the spring and fall but some sort of combustion source will win in the dead of winter. Traditionally NG but probably propane which is holding steady in price so far, wood or corn or other biomass this year. Maybe even electricity. TVA has only increased its rate by 7% which pales against predicted increases elsewhere.
I'd want to have at least two sources of heat and preferably 3. I actually have 4, counting the wood stove. Electricity, NG, propane and wood. I have a NG furnace with a heat pump A coil above it so two of my sources operate from the same thermostat. Just a matter of which one I flip the switch on.

It's not a controlled lab test, but one encouraging reality is that the Bruderhof in New York have been running 10 unmodified Jettas on filtered French fry oil from fast food places for a few years. No problems so far, altho they change the fuel filters 4X/year, more often than usual, because of particulate matter.
These are oldish cars, so maybe that's different. They also "converted" an old Mercedes. Each car has a 5 gal veg tank in the trunk with a heat exchange coil from the radiator. In winter, they start on diesel in the original tank, switch to veg after a few minutes, then switch back to diesel before shutting down. In summer, they don't use diesel at all.

Not the price of the coal that is what is most used to generate electricity.
Usually for the natural gas component of the electricity generation.
Natural gas has indeed gone up in price, but not because the price of crude oil has hiked recently.

Pathetic, really.
The price of coal has othing to do with the price of oil.
Like hell they do with coal and oil or uranium in spades.
Time will tell on that last.
No doubt because only a terrorist would want to ship something in dry ice...
By the way, the people at airribs.com use gel packs and two-day shipping, so unless they're screwing it up badly[1], apparently it's possible to do it without dry ice.

You wont see too many looting biodiesel supplys when their car cant even use it.
And it would be a public service to put a bullet in those so stupid that they cant work out the difference between biodiesel and gasoline anyway.

Lie with what the electricity generators use.
And what changes have occurred have had nothing to do with the price of crude oil anyway.
Old Rod is a binary sort of guy. You either agree with him 100% or you're a liar. Google his posts by using the words "Rod Speed liar" some time when you are bored.

Not a waffle at all--in fact, it is what I said in the first place except you can't seem to read "related" or "correlated" as anything other than "move in complete unison together". Nuance doesn't seem to be a strong point. :(
No, fact that explains the issue of U doesn't track as much as other forms.
Unless, of course, one is Australian, which just so happens to have been the analyst. I used it simply because it was one of the first (but certainly not the only) references that was convenient...
....
Only if one wishes to ignore events. Certainly those buying coal in large volumes don't.
....
And what powers those unit trains???? ....
Ask the guys in the mines--I suspect they'll beg to differ. ....
Could have fooled me--when the lights went out in MI and some other upper midwest places a few years ago during the severe cold/wet spell and they couldn't get enough coal unfrozen out of the cars w/ their reduced on-hand stockpiles, it was a major issue. (Detroit Monroe plant for one).
....
That remains to be seen...
And winter is right behind...
Which is a relatively short period--not yet clear that there will be much revamping of coastal facilities in time to have any (positive) impact for this winter.
I understand it well, thank you...
See what? That higher fuel production and distribution costs aren't going to effect the cost of generation? Doesn't compute out that way in my checkbook.
....
Well, the same could be said about a very high fraction here as well and it hasn't seemed to change consumer demand very much, at least as yet. I don't expect the Chinese who are just now learning the pleasures to be any more willing to give those up...
