They also made something similar to natural gas snip There really are no magic additives, or fuels that will give tremendous savings on their own. Well there is one, tetraethyl lead boosts the octane rating allowing you to use much higher compression ratios. True it indirectly contributes by raising the octane rating which allows for much higher combustion ratios. Gone are the days of gas engines with 11:1 compression ratios. Of course there certain drawbacks which caused it to be banned. Not just the lead. The higher compression had a tendency to create a lot of nitrides. Most cost far more than normal gas. Even those who make the claims of tremendous added mileage by adding battery capacity to a hybrid car are not taking into account all the added costs including the cost of the electricity. Not exactly. Using battery technology allows the IC engine to run only at its max efficiency setting and allows the use of regenerative braking Its easily shown that hybrid cars do give better gas mileage That wasn't quite where I was headed. I agree the hybrid can get much better mileage than a conventional car although it's at its best in city driving. Where I was headed was those adding more batteries to the hybrid and then charging them from the electrical mains. Although at first it looks like they are creating tremendous savings, it really a very expensive proposition and we haven't reached the point where disposing or remanufacturing the NiMH batteries has become a problem. Although the technology could allow the gas engine to run at max efficiency that isn't necessarily the case so there is still room for improvement. Yes, the motor/generator (wheel motor) is where the car gets most of its efficiency and also why it does its best in city driving. I'm wondering if may have noticed the similarity between the auto industry now and the auto industry back in the 70s after the gas shortage. The US auto industry was hurting as they were still geared up to produce cars that were part of the horse power race and consumer purchasing habits had shifted to imported economy cars. It appears, at least to me, to be much the same at present. We conserved, gas became cheap, and within a few years we were back to larger cars. However some pretty big strides were made in gas mileage. I drive an SUV that gets better mileage than the 4 cylinder cars I drove back in the late 80s and early 90s. but gas mileage has actually dropped slightly on average over the last 5 years or so. Some where in the $3.00 to $3.50 range per gallon of gas is the point where alternative fuels begin to become economically viable alternatives to non renewable hydrocarbons. They have been well above that level in Europe for at least a decade. The result has been a large scale switch to more efficient diesel engines and the proeuction of relatively small amounts of bio-diesel. Beyond that there have been relatively few such advances. And you have much quieter, smoother running, and cleaner diesel engines than we do here. Most of ours sound like a bad case of spark knock or a loose rod. :-)) Current gas prices here in the UK are around $6.8 per gallon We see all kinds of claims using byproducts from one place or another, but as soon as enough people use those products they no longer are thrown away they will be right up there with the other alternative fuels. We are most likely going to soon see $3.50 per gallon for a short time here in the states. That will affect world wide prices which should only be for a few months depending on how fast refining capacity can be put back on line. Dont bet on it. World demand is rising faster than supply, specifically the Chinese are rapidly building a massive automotive industry and Chinese demand for oil is rising at around 1 bbpd / year In 2004 China became the worlds second largest importer of petroleum products surpassing Japan. That demand is now at approx 40% that of the USA having risen by 300% since 1990 True, but due to price controls they are exporting refined gas as they can sell it for more than they can at home. I'd answer more but there's a thunderstorm right outside ... :-)) Later. Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com The scary part is the news tonight was reporting a gas leak out in the gulf where the lines come together before the gas is brought to shore. Wait till you see your LP and natural gas bills this winter. Most commercial electricity is produced by burning natural gas. Only if you include dual fired units, the stats in 2004 were (million kilowatts) Coal 313.3 Oil 36.9 Gas 222.9 Dual Fuel 175.4 Hydro 79 Nuclear 99.6 Electricity production is of course much easier to switch to non fossil fuels than automotive fuel use but the USA hasnt built any commercial nuclear plants since the 1980's unlike France which now generates almost 90% of its electricity from nuclear sources.

A lot of stuff seems to have done a bit of moving around out there. Given the two opposing movements produced by a hurricane and the shallow water in which the "Henry Hub" is likely to be located, far less than 100 fathoms, I'd guess early on that the amount of movement caused by the initial outflow of water toward the storm, followed by the surge, are likely to have exceeded the limits of one of more of the flexible couplings attaching the collectors (or the shore line) to the hub. One problem is that the waters are filled with stirred up sediment and sand and will take a while to clear for suitable diving conditions - They are never very clear. - and the second, pre-dive if possible, isolating the line(s) the coupling(s) of which is/are leaking and shutting off the flow of gas. I'm sure the structure has a valving system installed which prevents cross and back flows. The natural gas price issue is less clear than the superficial reaction makes it out to be.... I own a small interest in a gas producing property, itself a few wells which share production from a single underground "pool" of natural gas under pressure. This production is generally sold under contract, in our case to Phillips which owns the nearby pipeline which collects the gas. When the price jumps as it has and will this winter, our earnings will be dependent on the terms (and the time) that have been negotiated for the gas. Would that there were no contract, today, for I'd get fat and happy quicker. The result, gas burned to make electricity or piped to home or industry, which has been purchased at several different prices. Overall, I expect natural gas's "overall" price increase to be in the 30-35% range this Winter. ......But have I got a deal for you (or for me, really). Over on the edge of East Texas, I own what is now a 1/25 interest in the "Mineral Rights" to 532 acres+/- in the 1911 survey (actually now 540 acress by the survey when the "land" - surface rights - was recently sold). 15,000 feet (and $3-5,000,000 worth of drilling) beneath the surface is natural gas, by all evidence and indication in production quantities (which means that a dry hole is possible, but that the risk is acceptable). If a production company knocks on the door ready to drill (and willing to pay an acceptable percentage), the potential value of the gas, all "new" and ready to be sold at today's spot market prices, 2 or 3 times that of old gas, is substantial. The poor *******s buying "country places" and "ranchettes" up top have no say in the matter and would only receive token payments and compensation for a drilling rig in their backyards or a "Christmas Tree" next to the car port. As for me, I'sd be planning vacations, long vacations, permanent unemployment and relaxed retirement. I stand corrected on the % of coal Vs Gas generated electricity.

Damages aren't "chicken feed" where I'm from. I know some people who have completely paid for their land from damages alone. Also, the surface owners do have a say, at least around here. They can negotiate water wells, fencing, brush clearing, location placement, road building, cattle guards, etc. That's not to say they always get what they ask for... but if other oil companies are competing for the same parcel then often they do. Do you mean you own one twenty-fifth share of the production or are you saying you own one twenty-fifth of 740 acres of the minerals. If it's the former is that all they will allow you as a sole mineral owner. We are getting 1/4 to 3/8ths of the wells production. What is the going lease rate per acre? I suspect yours is much higher than ours. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com Roger, How much pressure does the average well have on it in your local area? How deep do they drill up there? Most leases around here are for 3 years and are 7500 to 9500 feet deep. Some go to 11000 feet though. A few wells have up to 10000 psi of pressure on the casing but most local wells are a few thousand. We are currently undergoing the biggest drilling boom since the early 1980's. South of here 60 or 70 miles are some wells that are over 20,000 feet deep. ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

" wrote It sounds reasonable that injecting H2 into your fuel stream can improve the combustion. Hmm, I dunno, I feel a little puzzled or suspicious of how he's achieving a net energy gain here. Can anyone debunk any obvious fallacies here? I'm not up to trying to read all of the web site, but the answer is to save your money. Water injection has been around in high HP engines, running at high, constant loads, for a long time. Will it become practical for your airplane or car? Car, no, because of the low HP, and non-constant loads. For airplanes? Yes, if all you want is a boost of extra HP, for a short amount of time. Some WWII fighter planes used them for an extra boost for take-off and for other times, such as dog fighting, where the extra HP meant life or death. Some air racers also use water injection. Why not all of the time? LOTS of water is needed to make much of a difference, and the weight for enough water to last for more than a few short bursts would be impractical to carry around. It also needed a lot of monitoring, which no doubt could be taken care of by modern micro chips. Lastly, if it was a viable option, wouldn't all major manufacturers be using it? You will have to ignore the oil company conspiracy theories, to answer that one. g Well, water flashed to steam expands a lot. I knew a guy when I was in High School, good fellow, into his moped, car, etc. He rigged up a water injector on his moped to supercharge it, and got some serious power, until he blew out his engine. Got a heck of a battle scar on his leg, too.... but it was cool while it was going. Glad he wasn't hurt worse, he was a great guy. The huge increase in pressure is probably the reason. Building the engine to take that for longer periods would probably mean so much weight that it took the advantage of the extra power away.

Can you explain the octane rating? In my little world octane is a chain of 8 carbons with 18 hydrogens hooked on. It's how resistant the fuel is to spontaneous ignition. (Detonation) Octane Rating really only applies to numbers below 100. The detonation resistance of a fuel blend is compared to that of a blend of iso-octane. An octane number of 100 is equivalent to the knock resistance of 100% octane. Strictly speaking, numbers above 100 aren't Octane Numbers, but Performance Numbers. It has nothing to do with energy content. The energy content of petroleum based hydrocarbon fuels is actually fairly constant, at somewhere around 18,000-19,000 BTU/lb. (Density, of course, varies. Gasolines are consedered to weigh in at about 6.0 lbs/U.S. gallon, while Kerosines like Jet-A weigh in at around 6.7 lbs/U.S. gallon.) In fact, most high octane gasolines have a lower energy content than low octane fuels. The increased knock resistance allows the engine to use that energy more efficiently. Methanols are considered to be around 150 Octane (Well. Performance Number) - but the energy content is low, so you've got to burn a lot of it, and it doesn't atomize well, so carburetor jets and injectors need to be redesigned. -- Pete Stickney Java Man knew nothing about coffee. |
