Although it may be hard to believe, many cities have suffered greatly due to suburbanization, but at the same time real estate costs have just completely dropped. With property values so low and housing being dirt cheap, people have found that it's a lot cheaper to buy a house. Even though real estate values are now rising because of this realization, it's still considerable cheaper to live in the city. Sure, things like car insurance and taxes may be high, but even this hasn't stopped people.

      Also, most of the people moving back have found that new construction is bad. The term "cardboard houses in cornfields" best describes the production line trait of new housing. Before homes used to be build out of stone, bricks, mortar, and plaster walling. The craftsmanship that used to go into a house was at one time immense. The new city dewellers realize this and love living in older homes that have much more character.

      Here's an article about pollution due to vehicles from the New Scientist. It shows that diesel produces about 33% less greenhouse gases than gasoline. As for the other negatives of diesel, who says we can't do better? People don't drive diesel cars in America because it isn't important enough to care about the benefits of diesel. Diesel cars are so popular in Europe because of how expensive fuel is and running a diesel car is more efficient.

      Actually, I happen to like cars quite a bit, but I also see the value of city life. I don't advocate forcing people riding bikes everywhere either. Let's just look at simple logistics. You have to drive many miles to get to a store in the suburbs. You could walk, take public transportation, or drive a short distance to the same store in the city. The thing is that driving in the city is not a necessity, it can be done if you want to or not.

      And about moving to the city, you don't seem to understand what city life is all about. City life isn't about living in Manhattan on the 50th floor of a high rise appartment. City life isn't about what you watch on TV or in movies. Most people who live in cities either live in apartments, row homes, doubles, or singles. One size doesn't fit all. No one forces you to live in any one kind too! You can live with your half acre of ground or you can live on a street with nothing more than a sidewalk or you could even live on a street with both. I know it seems like a bizarre idea since most people only know what they see on TV. The fact is that housing is incredibly diverse in most cities, especially ones in the Northeast. Just find your neighborhood and you'll be happy.

      As for the whole train option, you seem to miss the point. Mass transit helps to lessen pollution because of economies of scale. If you get your electricity from nuclear, hydroelectric, wind, etc. power, electric trollies are an excellent option. Riding a bus, subway, or train can lessening traffic and take advantage of having one engine power 40 people instead of 40 engines. The whole point of mass transit is that if you have a place you go everyday, like work, then you take the same bus, train, trolley, or subway everyday. You'd then have a car when you want to get somewhere on your own time. You could even take your car to work everyday and this is more desirable because the drive would probably be shorter.

      I'm not saying everyone needs to ride bikes and take public transportation. I'm just saying that if more people lived closer to where they work or could easily take public transportation to where they work, then the need for fuels goes down greatly. If more people could easily walk places instead of being forced to drive, the need for fuels go down. My whole point is that people need choices. Choices don't exist when you live out in the middle of the suburbs and have to have a car to get anywhere.

Diesels are smoky and black, whereas gasoline based cars and trucks don't produce anywhere near the same amount of soot. Therefore, diesels are worse for the environment than gasoline engines.

If the northern ice cap melts, we'll have a large expanse of open water north of Canada. Suddenly, the arctic desert has plenty of water. It's still cold most of the time that far north, as we're only talking a few degrees needed to melt most of our northern ice. So we have an assload of water in what was a desert, and it starts to snow all the time. As it's still fairly cold in this area, the snow builds up fast, a glacier forms, the next ice age comes along, and that glacier begins its plow-trip down NA to make another Long Island.

      I'm definitely not arguing for continued use of petroleum as our fuel source. But I do question if burning things is the best way to get our fuel.

      Essentially, we on earth have 2 ways of getting energy. We can either use up limited resources - fossil fuels, nuclear materials, etc. Or we can use the only source of energy that from the perspective of the earth is truely renewable - the sun.

      The sun keeps pouring energy on the earth and it's ultimately the source of all of our energy. Coal and oil are simply captured sunlight from millions of ago (carbon and its chemical bonds are the storage device). As a planet, if we consume any more energy than is delivered by the sun, then we are on the path of ruin because it cannot be sustained.

      So, what we really need to ask is this. Is taking the sunlight we have (a limited resource at any given time), converting it to plants that we then process into oil and then burn for heat energy the best way to get sunlight into a useable energy form?

      Burning plant products is just one way of using this energy. There are several ways that tap recent energy sent by the sun:

      hydroelectric - the sun's energy provides most of the energy needed to drive the evaporation part of the water cycle

      wind power - again, the wind is powered by the sun's energy

      plants - through photosynthesis, plants take the sun's energy and make chemical bonds

      photoelectric cells... to name a few

      Using each one has its own side effects and compromises. But we really need to pick the one that gives us the most efficient way of taking the sunlight we get and converting it into energy we can use.

      In any case, if we as a planet cannot find a way to live within the daily energy budget of the sun (we have current "cash flows" and our capital resources (minerals, oil, etc). We cannot sustain ourselves by eating our capital for daily operations. So, we have to find the best way to make use of that daily cashflow. Otherwise we go bankrupt and the cockroaches get their chance.

      And as for things like "long hot spells in the summer, forest fires, dead fish, water shortages, freak weather, etc", shit happens. These kinds of things can happen whether we cause them or not. Yes, our actions can contribute, and probably are right now. But humans are really whiney and get bitchy when things aren't what they expect. People go nuts just when traffic is bad. We need to suck it up and realize that the biosphere is a self-regulating system. And if we're not careful, we'll be self-regulated right off it.

      In the grand scheme of things, it's all going to be incinerated when the sun expands anyway - and everything will be gone.

And I'm sure you've all seen the Propane delivery trucks that carry a few thousand gallons of the stuff. I like to refer to them as bombs on wheels.

      Hydrogen is lighter than air, so if there is a leak, it will rise and dissapate naturally eliminating the fire hazard. It burns cleaner than any of the previously mentioned fuel, producing only heat and water as a by product of combustion.

They rely on the controlled reaction of hydrogen with oxygen to generate electricity, but the former reagent -- hydrogen -- does not exist on earth in free form. Accordingly, to 'charge up' a fuel cell, one must subject water to the process of electrolysis, splitting it into its component hydrogen and oxygen. The hydrogen is stored in the fuel cell, and allowed to react with atmospheric oxygen when required.

      The problem here, of course, is whence cometh the energy to split the water into the hydrogen and oxygen? It must come from conventional power sources, since fuel cells themselves do not generate power -- they only store it. So, the fuel cells you are paying obiesance to in your post could, quite conceivably, be powered by the nuclear reactions you appear to have an aversion to. How, then, are fuel cells safe?

You'd think, like this poor person, that you are carrying a nuclear detonation device in your car with hydrogen fuel. Let's compare the explosive power of hydrogen to the explosive power of gasoline. One cup of gasoline contains the same explosive power as one stick of dynamite. Now one cup of hydrogen has significantly less explosive power than dynamite. Hydrogen has a slower reaction rate as well, making hydrogen more of a flame than an explosion. Notice, for example, the Hindenburg did not explode. The hydrogen did burn, but had the ship been inflated with vaporized gasoline there would have been a rather large blast killing everybody in the air and on the ground. Hydrogen actually has other advantages as well. At room temperature and pressures it is a gas, while gasoline is a liquid. If a hydrogen tank cracked, the pressures needed to store it would force the tank dry in a matter of seconds. Hydrogen disperses quickly in the atmosphere, and burns off quickly so a devastating accident would not burn for more than a couple of seconds (you'd see a very brief ball of orange flame). Gasoline on the other hand, acts more like napalm. It's liquid at regular temps and atmospheric pressure, so it has no problems spilling and leaking everywhere. If it catches fire, it burns quite well and for quite a while. So hope you don't have any on you. Not to mention if there is a pocket or two of vaporized gasoline you may get some explosive results. Gasoline is a far more dangerous material, not to mention toxic (hydrogen gas is non-toxic). But hydrogen would be piss poor in a combustion engione because, as noted above, it doesn't pack the same kick as gasoline. Using hydrogen in fuel cells is a better way to go. No combustion necessary. Now I'm sure someone will bring up the challenger disaster and say "See, hydrogen is bad!". That's not accurate. It wasn't the hydrogen that was the problem, but the LOX (liquid oxygen). LOX is highly explosive,and that's what made the really big boom. You can have a room full of hydrogen, but it won't ignite without a supply of oxygen. I think a big step in getting hydrogen into public acceptance would be an education campaign.

Deserts near the ocean are rather few and far between, though I suppose pipelines could be built. But it's much, much simpler to set up an algae farm in the desert and produce massive quantities of Biodiesel, also from solar energy.

      Overall, hydrogen is simply not a good energy source unless we can find a way to produce it cheaply (not going to happen, I don't think), and can find a way to store it without putting it in high pressure, highly explosive canisters.

      Biodiesel, on the other hand, runs well in current diesel engines, and even better in ones that have been slightly modified; uses essentially the same distribution system we already have in place for gasoline (gas stations with gas pumps) and as such would require practically no changes, other than people buying cars with diesel engines next time they go to the dealership. Restrictions on the sale of gasoline driven vehicles would accomplish this quickly; most people will buy a new car within the next 5 years, and those that don't can be "encouraged" through taxation on the sale of gasoline; not to mention that with gasoline officially a "dead end", gas stations would probably start serving up diesel in preference to gasoline pretty quickly -- the market would demand it, anyway, as the number of diesel cars overtook the number of gas cars.

      And this wouldn't even need to be artificially subsidised, because once the refineries and such are in place, biodiesel produced via algae is cheaper than gasoline, which is CHEAP. So all you need is a little "push" from the government to head that way and the market will shift, no problem.

      If we started this sort of legislation today, we could be running entirely on biodiesel in 15 years, with I would say more than 80% of vehicles on biodiesel in 10, and 50% in 5. That's really fast, when you think about it.

      Of course, the question is, is biodiesel as profitable as oil, and the answer is probably not, but I suppose you never know. This would mean that oil companies would probably not be in favor of the switch, and they've certainly lobbied successfully against other beneficial non-oil based technologies before (electric street cars and trains come immediately to mind).

      But one can always hope. It would be nice if people stopped pursuing technologies that will never work, like hydrogen, and concentrated on something that actually could work.

The fermentation of the carbohydrates (sugars) in corm by yeasts produces carbon dioxide as well. Additionally, Corn is a C4 metabolism plant and it requires significant irrigation for maximum yields, and irrigation requires the burning of fuels either at the electric plant or rurally to pump out an aquifer to water the crops. Fuels are also needed for the large tractors, combines, and other equipment used to grow the crop. Another important consideration is the significant government subsidies given to grow corn in the US. The market is artificial and controlled, fluctuating with the weather (crop yields), whether a Democrat or Republican votes to adjust the already high corn subsidies (at taxpayer expense), and there is added manpower, use of significant agricultural land for fuel production, etc..

If it were Hydrogen (H2) produced from electrolysis (electric current through water yielding Hydrogen (H2) and Oxygen (O2) [2(H2O) + electricity = 2(H2) + 1(02)]), and that electricity was from a solar, nuclear, or hydroelectric generation station, then I would say that the use of that Hydrogen in a fuel cell solves much of the CO2 emissions and reduces dependence on oil.

    Read the nice article, American. Ignore the lack of Russian development of said oil for the last 50-80 years (which would easily have fixed many of their huge energy woes). Digging deeper was what they were good at! Someone's apparently selling us sheep oil.

    Abiotic oil is not possible from imaginary methane underground. Methane is impossible to bond with unless you oxidize it (oxygen) or rip away its hydrogens in some other way (without letting them re-join the carbon) and it's very light (rises) and its very very likely *not* sitting in rock solution, as an unoxidized carbon source near the pure silica mantle.

    Oil is not "cooled" methane or propane. Geesh! what a rip! You have to cook up long molecules from more complex carbon soup. Gases occur because they couldn't get cooked! The natural gas we pump out has risen above the oil because they were formed around the same time and don't slowly go from one form to the other. You'd never find them togther if fluid temperature changed one into the other.

    Besides, the proportion of carbon in the unruly methane gas is much smaller than the goo that was buried under tar pits and other sedimentary formations. Methane is hydrogen-rich and carbon-poor compared to coal and crude oil. Ergo: one don't magically all change to the other over eons.

    Simply said, we (made of carbon) are the scum of the earth: carbon forms and compounds of *every* type are light and do not flow anywhere but up when buried deep. Even when compressed over eons with silica compounds, they still always come from the surface. (Obviously shows in coal, more common than oil!) So there's no magic springs of texas tea going to appear from 10000 miles deep oil wells. All the oil that was formed 60 million years ago has risen as high as it can, or sprung out already as tar sands.

    Okay. Here's a simple test: do endless methane flares spew out of deep-fault (or any) volcanos? Nice pictures in Nat'l Geographic? NO!

    Methane was in the atmosphere like every other gaseous carbon compound when the earth was formed. Gooey carbon chains were formed when that carbon in methane stuck to rocks in the form of algae and stuff that ate it. Carbon is light stuff!

Furthermore, it fits in quite well with current engine technologies and gas distribution infrastructure.

    My second comment regards hydrogen production in the future becuase of course there is pretty much no way we could grow enough crops to fuel all our bloody cars with biodiesel so moving to hydrogen produced using renewable (biomass, solar, wind etc) electricity is a good option. As fas fusion goes, it won't be ready for some time (if ever) and it still creates radioactive materials to be disposed of and uses large amounts of water for cooling which could be used, in places with poor water resources, for better things like keeping people alive! So if we spent the $100 billion on solar energy or wind, we could get (at $1/Wp solar and $0.3/Wp wind) about 200GWp installed which is something on the order of 2,000TWh/year - just to get an idea of how much that is, Canada uses about 0.5TWh/year (http://www.statcan.ca/english/Pgdb/prim71.htm).

    WASHINGTON, Aug. 12 /U.S. Newswire/ -- Contrary to popular myth the Earth is not warming significantly, according to new research published last month in Geophysical Research Letters by scientists with the universities of Rochester and Virginia.

    The reports note two important findings that run counter to the view that human activity is causing catastrophic global warming.

    "It's been known for some time that satellites and surface thermometers give different temperature trends," said one of the reports' co-authors Prof. S. Fred Singer, president of the Science & Environmental Policy Project (SEPP). "We now have independent confirmation that the satellite results are correct and that the climate is not warming." Prof. Singer, an adjunct scholar with the National Center for Policy Analysis (NCPA) is also a former director of the U.S. Weather Satellite Service.

    Proponents of global warming theory have long pointed to thermometer measurements at the Earth's surface as proof that the Earth is warming. Other scientists have pointed to balloon and satellite readings of temperatures in the Earth's lower atmosphere that show no significant warming. The scientists from the universities of Rochester and Virginia employed a new, independent way of determining the temperature, using historic meteorological climate data to construct temperature values for each grid cell of the Earth at an equivalent height of two meters. This analysis agreed with the satellite and balloon measurements, establishing that the disparity is close to the surface and mainly in the tropics.

    In another report, the Rochester/Virginia scientists found that the computer climate models used to assert that the introduction of greenhouse gases, like carbon dioxide (CO2), into the atmosphere is causing the Earth to warm, and that the effect increases with altitude becoming twice as strong at about three miles up, are in stark contrast to the actual data of the past quarter-century. Comparing the results from the three commonly cited climate models with four independent observational data sets, the scientists found that the models all showed temperatures increasing with altitude, while the actual observations showed the opposite occurred.

Why make some country overseas rich when you can grow your own fuel and keep the money in country? Any country that buys more than it sells from other countries is giving it's wealth away. Spending the money closer to home makes your economy better.

    So it really doesn't matter what year the supply peaks.... the shortage is already here and probably will get worse from here on in... year after year... until by 2025 we are burning as much oil as was burned in the 1950's.

    This is unless alternatives can be found. Nuclear fission is probably the only reasonable source of relief, but we would need to undertake a reactor building program that results in 1000 new reactors each in the gw(e) range. This is 10x the number of reactors presently in North American. It is a MAJOR undertaking.

    Furthermore these reactors should probably be heavy water moderated natural uranium buring reactors like the Candu. Meanwhile fuel re-processing technology must be developed at break neck speed. This will solve the waste problem for the most part.

    And what of the fuel cells?

    I suspect they will not be viable for the foreseeable future for the simple reason that hydrogen is hard to transport. In fact, the easiest way I know of to handle hydrogen is to mix a little carbon into the molecules!!! Once we get the ratio of H:C into the 2:1 area we have nice, relatively safe and easy to use liquid fuels.

    To do this we need a carbon source and one of the best I know of is the Tar Sands of Alberta. The upgrading facilities to do the chemistry are already built, being built or are in design. All we need to add are some rather large nuclear reactors and we are well on our way to making the fuels we need.

    So lets start lobying the Alberta and Canadian governments and lets get some reactors underway.

    The sooner we start the better!!!

    U.S. oil production has been declining for decades (as predicted by people who used a similar logic to the current predictors), long before environmental concerns had a big impact on drilling. The decline continued during the period during the 1980s when large offshore leases were made by the U.S. government and the Alaska oil came on-line. (Of course, this is not necessarily an indictment of those who argued in favor of those moves, since none of them were so stupid as to claim they would reverse the decline in U.S. production.) No serious observer claims that the U.S. "stopped looking" and surely no reasonable expert has ever made the case that the decline would be reversed if we "started looking again."

    I would love to get Sybert in a room full of oilmen to see their reaction when they realize he doesn't know the difference between reserves and production. Indeed, one only need look at the problems of Shell Oil in the UAR to see that some of the recent drops in reserves have come from unanticipated problems in production.

    Sybert ignores the article and the blog that points to the article. Then he spouts provably false propositions about a vaguely related issue. Then he spews pure ideological nonsense about military and scientific advancement on the oil front.

    All the construction that I have seen being built is either "retirement flats", "executive homes" (only a very few), or "professional couple apartments". The unfortunate thing is that the retirees want to live in bungalows, so they don't have to climb stairs, professional couples really want houses, so they can prepare to start a family. I believe the phrase for the small apartments being built is "vasectomy housing", since they are deliberately designed to be unsuitable for children. This policy is mainly due to the PC goal of not building on the green belt but to regenerate brownfield sites.

    What has happened to Americans? We no longer seem to just want something that will work smoothly, we want the MOST EXOTIC and COSTLY, R & D-intensive answers we can possibly eek out! Professor Abe Hertzberg of the University of Washington invented an engine that runs on compressed air. It didn't have a lot of power. It had a few design flaws. I figured out what they were and fixed it. www.newpath4.com/steamedheatengine.html is my earlier collection, but I've explained the process completely on this page: www.newpath4.com/icyhot.htm . It is entirely possible that the collision of hot steam moisture with liquid nitrogen -having a combined temperature spread of 640 degrees- may cause the creation of an energy plasma as the energies meet inside a cylinder. ABC News did reports on Hertzberg's engine but no one wants to do a report that I fixed it to have lots of power, nor that I also disposed of shocks & springs and replaced those with re-compression pistons. In other words, my solution engages the kinetic energies of a car in motion, stopping, starting, turning curves, to RECOMPRESS MORE NITROGEN BACK INTO LIQUID. The energy of the moving car (or truck) makes more fuel by imparting those kinetic energies back into more pressed nitrogen (stored potential energy). The engine and car work in a symbiotic relationship constituting a closed loop where power is not wasted. The temperatures inside such an engine balances out, and cancels out, so there is no need for the entire radiator-coolant system, hoses, water pump. The cold nitrogen cools its own self but the steam keeps it from overcooling (engine freezing), one of the points where I advanced Hertzberg's engine. Some of you /.'s are a bunch of freaks. You aren't satisfied to have a wonderful self-replenishing engine. You're a bunch of greedmongers who have to have a HYDROGEN engine. I guess you all want Star Wars and Princess Leai too eh? While you're at it try wishing for a light saber. Hydrogen is a bunch of phooey. Even if it can be made to work it's years down the pike, maybe even a decade. Have you even considered what the scientists are saying on all sides of the aisle?, that the CO2 and other engine contaminants are poised to go exponential? We don't HAVE a decade. The steam-nitrogen dual catalyst engine does just what it says. The hot steam acts as catalyst to force the liquid nitrogen into instantaneous expansion, and the nitrogen catalyzes the H2O in the steam into an instantaneous collapse, which creates an instantaneous VACUUM collapse AHEAD of the expanding nitrogen. The molecules never touch til long after their energies react to each other. It is in fact a rather exotic engine process itself, but you guys are so tunnel-vision damned you can't see straight. Let's say we get a hydrogen engine in 2 years. People won't buy it til their present car falls on its knees, so the environment still continues downhill another 15 years while people keep their old jalopy running. My engine process could be designed into existing engines, replacing plugs with nitrogen injectors and using the intake port for steam. And it would NOT take 15 years to see some real improvements in the environment. What it would do is get the OPEC's and J.Paul Getty's off our backs. Everyone who is pushing these other technologies down your throat are interested in one thing: YOUR MONEY. They're building cars so complex you HAVE TO PAY a company-trained technician, not a car mechanic. In a few years these people will be demanding, and getting, $40-$60 an hour. Do YOU make that kind of money??? My engine won't need a mechanic. It won't overheat. It never quits, and it never gives up. It doesn't even need a starter, instead using the compressed nitrogen to turn over, and at a light it will run so slow you won't even know it's running. It will be almost as quiet as a Zalman.

If more is needed, we can use land that is now unused (the great plains), to grow switchgrass without the need for any tilling, fertilizers or irrigation. Therefore it wouldn't add to the water shortage and soil erosion problems and it wouldn't have to replace food crops. *Proton Exchange Membrane fuel cells require 100% pure hydrogen. They're finicky, expensive and tend to degrade quickly. Yet that's where most efforts are in automotive fuel cells. Solid state fuel cells can take very impure streams of hydrogen and turn them into electricity. Unfortunately, they operate at extremely high temperatures. The point in my article is that we should be concentrating our national fuel cell research budget on ways to make solid state fuel cells cooler and on materials research to find cheap building blocks that can withstand such temperatures. Just last week a University of Houston researcher reported a breakthrough that cuts the operating temperature of solid state fuel cells in half. That's a huge step. *We're Not Anywhere Close to Being Ready for Fuel Cells--the technology is immature and may never be economically viable. My article puts forth a game plan to provide a halfway step (cellulosice ethanol to be burned in internal combustion engines) as a halfway step to a fuel cell transportation economy. *Biodiesel Works Too--Biodiesel is a great technology that also makes a lot of sense to continue to research. Unfortunately it's nowhere near as close to being economically viable on a large-scale basis as ethanol. In addition, it requires the use of food-rearing agricultural land to grow energy crops (safflower, soybean). Future biodiesel might be harvested out of genetically engineered algae grown in seawater pools in deserts. Cellulosic ethanol is far more advanced. *Kerry's Energy Plan--It is an extremely timid version of what I lay out in my article. He wants 20% of our fuel to come from renewable resources by 2020. That's easily achievable. A presidential candidate with some vision could make us petro-import-free (except for Canada and Mexico) in ten years.
