The value of electricity makes almost any location cost effective. Put a solar farm on that corn field. The electricity will be worth far more than the corn. A wind turbine doesn't take up much space on the ground, maybe 400 square feet. There is nothing you can grow on 400 sq. ft. worth as much as the electricity produced from that one turbine-bearing mast. — Bitter Crank
Here is your problem:
You are assuming that "the truth" is crisply, concisely, and clearly stated in clean Helvetica text and that the upshot of seeing the truth is equally obvious. That's not the way truth usually appears. More likely than not it will be laboriously spelled out in obscure language and printed in some barely readable obscure font (figuratively speaking, you understand). Then one has to figure out how to implement the truth that one has understood (correctly or not). — Bitter Crank
No offense, but I understand that this is just too vague to keep my interest. Let's try again in another thread, and thanks for the chat. — Jake
Hydrogen is simply not a good energy carrier for a few reasons. First, it's not a liquid or solid at ambient temperature, which is a big inconvenience. Second, hydrogen is so small it diffuses through most metals causing micro-fractures leading to failure; solving these problems to power a rocket or in industrial processes can be solved ... but scaling to a transport infrastructure this problem is essentially unsolvable. Third liquid hydrogen boils off and easily slips through the tiniest cracks between parts making it extremely difficult to make a hermetic sealed hydrogen system at a lab level and simply impossible at an infrastructure scale. Hydrogen floats to the top of the atmosphere where it acts as a potent green house gas. — boethius
Long story short, if you have a lot of hydrogen you may as well solve all the above problems by reacting with carbon to make hydrocarbons and have all the benefits the energy density of hydrogen without the massive technological hurdles. Since there's excess carbon in the atmosphere it's easy to get to do this and means not only a cheaper infrastructure to build ... but an infrastructure that already exists. — boethius
So the thesis of the OP is essentially correct, there's just no reason to use hydrogen by itself as an energy carrier. And since you'd need to make electricity first to make hydrogen to make hydrocarbons (or whatever analogous process), you may as well use that electricity directly for most transport needs. Electric trains, trams and batteries for personal transport is simply far more efficient if you already have electricity. "Synth-hydro-carb" fuel would still be useful for trucks and lorries and airplanes . — boethius
Summary: One can get a profound change through the market mechanism when a new alternative is cheaper and better to the old one. Yet the typical solution is only to believe in regulation, restrictions and international agreements and not that the free market could (or would) change supply and demand itself. Hopefully I'm not confusing here. — ssu
"The concrete industry is one of two largest producers of carbon dioxide (CO2), creating up to 5% of worldwide man-made emissions of this gas, of which 50% is from the chemical process and 40% from burning fuel." wiki
That is to say, cement is produced by driving off CO2 from calcium carbonate (limestone). — unenlightened
In other news, as I tried to indicate earlier, the ocean is not as empty as it looks; covering it with solar cells is probably not as disastrous as covering a rainforest with solar cells, but not that far off. Why is life so complicated? — unenlightened
Did I recommend this author, this book to you?
Too Much Magic: Wishful Thinking, Technology, and the Fate of the Nation by James Howard Kunstler
Kunstler details the nature of the environmental crises. While doing that he also punctures many a delusion about what is possible. For instance: "We'll build huge numbers of windmills and square miles of solar panels." Great idea. But... given that we are past peak oil, what will happen when our million windmills and millions of solar panels wear out? We still have relatively cheap petrochemicals with which to carry out this production. Forty years from now? Sixty? Much less oil available and much more expensive. I am thoroughly enthusiastic about windmills and solar, but a lot of energy is needed to build the steel masts from which the windmills are hung. I assume a fair amount of energy is required to build solar panels too and that they probably don't continue to work forever.
Kunstler's point is that there are no magical solutions to our several interlocked environmental crises. — Bitter Crank
Take a larger view. in the years of WWII 1939-1945, horses were indispensable. Why? For one, they don't use oil. For two, they are strong. For three, they can be used flexibly. Four, Germany and the USSR still used horses for various purposes in 1938, and horses were part of military planning. — Bitter Crank
The first computer was built in WWII. It took about 40 years for personal computers to make their appearance. By 1995. they were pretty much integrated into business, and people were buying computers for home use. So, about 50 years. — Bitter Crank
The system I describe has all the thermodynamic efficiency of a steam train
— karl stone
Indeed, but if we could build large solar plants in the ocean at the equator, why wouldn't we just run a wire from the complex and plug it into the electrical distribution systems of India, China, SE Asia, Africa, or South America? — Bitter Crank
I've been attempting to say much more on this topic in the other thread, or we could do it here, either is fine. — Jake
Fundamentally, I am not asking man to manage the powers science makes available. I suggest they should be managed in relation to a modern day scientific understanding of reality; that is to say, the truth that provides the power should be taken on board in deciding how it is employed.
— karl stone
Ok, how does that work exactly? Can you be more specific? — Jake
I certainly agree that from a scientific point of view it would be preferable to choose the cleaner and renewable energy over the cheapest energy. — ChatteringMonkey
But I have my doubts that markets would put the science above the profit motive. They typically don't make any value judgments aside from the profit motive, right. Because that's what the stockholders want, more return on investment. And you get more profit when you sell more products or services. So the consumer decides in the end, and he typically will favor the cheaper products and services. — ChatteringMonkey
I don't see that dynamic changing any time soon, but one of three things could happen that will make renewable energy more viable economically : 1) the consumer will start to value 'clean and renewable' more as the situation gets more dire 2) governments start imposing more pollution taxes which drives up the price of the old energy sources, and 3) renewable energy becomes cheaper and cheaper in comparison, as technology advances and old energy sources get more expensive because of depletion. — ChatteringMonkey
Right, though there are only carbon costs if we assume that the energy used for construction or looking after the nuclear waste is itself carbon energy? — ChatteringMonkey
The nature of science is to develop knowledge, which typically is then converted in to some form of power, ie. an ability to manipulate the environment. — Jake
The nature of human beings is that we are imperfect, able to successfully manage some power, but not an unlimited amount of power. — Jake
Thus, at some point the nature of science and the nature of human beings come in to conflict. Science keeps developing more and more knowledge/power, and at some point reaches and exceeds the limits of the governing mechanism, human beings. — Jake
Your thread argues for the science religion dogma, the "more is better" relationship with knowledge. That dogma is the cause of the problems you are trying to solve. — Jake
If I knew what stolen consent meant I might be able to respond better. — fdrake
Let us say for example that a government put a question to an electorate in the form of a referendum - and then ran a false and divisive campaign for a particular outcome. Let's further imagine that the vote confirmed the proposition. Would that not constitute stolen consent? That is, consent to act on the proposition. It's not an oxymoron as government would appear upon the basis of the vote alone to have consent - but perhaps because the voters were misled, perhaps one could say - consent was stolen. Or do you not think a false and divisive campaign sufficient grounds? — karl stone
Stolen consent might not be defined, but manufactured consent is probably well understood at this point! — fdrake
It seems at least close to an oxymoron - if something is taken with consent, it is a gift; if it is stolen it is taken without consent. Not that you cannot use an oxymoron now and again, but you cannot expect analysis to reveal its meaning. — unenlightened
The problem of population, 7-11 billion, is that it is up against an agricultural environment that will be deteriorating, even if we make some progress toward limited CO2/methane/other. Those are:
All the arable land we have is now being used for agriculture. There are no significant idle reserves. (What about northern lands becoming agricultural? The soils that are now very cold or frozen are not, and will not be suitable for agriculture. What about irrigation? All of the fresh water that is suitable for irrigation has been tapped. Drinking water has also passed its peak. The Asian glaciers are shrinking rapidly. In 50 years, the temperature in many agricultural areas will be too hot to work in for much or all of the day. (When the temperature and humidity combined make it impossible to cool off, people start dying from heat.) Fisheries productivity is in decline.
Agriculture, under the best of circumstances, is risky: too hot, too cold, too wet, too dry, too many insects, not enough bees, plant diseases, soil exhaustion, etc. There is usually enough world production to keep people fed, but an increasingly warm, erratic climate doesn't favor agriculture. Projecting enough production to feed 11 billion ignores erratic and fast climate change.
Not despairing yet? — Bitter Crank
Declining hydrocarbon output: Much of high agricultural productivity depends on cheap, abundant oil and gas for chemicals, fertilizers, and fuel. We are past peak oil. We can not feed 7 billion people, maybe not 5 billion using animal traction, organic farming, and the like. We could do that at maybe 2-3 billion under good conditions. Those days are over.
Getting the population down to 2-3 billion or less will come about if the species crashes. That could happen if global warming becomes too severe in the 22nd century (only 82 years away). — Bitter Crank
I am pessimistic about all techno-fixes. I like techno-fixes. However, it does not appear that the we have the will or the political means to slam the brakes on CO2/methane/other. If we (the whole world) did have the will, the ways, and the means to abruptly cease CO2/methane/other output, we could, perhaps, solve the problem. But we don't. NO country is meeting even the modest targets set recent agreements. — Bitter Crank
Why not? Why are they not?
One reason is that major technological changes (like from horse power to machine power, like telephone, radio, television, railroads, highways, airplanes, medicine, engineering, etc. etc. etc.) require around 40 to 50 years to propagate throughout society. It isn't just behavior change; it's all sorts of changes. We have not committed to abandoning fossil fuels, so the 40-50 year change over hasn't begun. — Bitter Crank
Yes, there are solar panels and windmills here and there. But transportation in the developed world is still predicated on cars and trucks. Heating and cooling still are largely dependent on electricity from fossil fuels. A rising standard of living around the world requires more production of everything, and a lot of waste.
It isn't that I think we can not do anything; theoretically we can. But we run up against time (we waited too long) and material limitations on what is possible in a short period of time, because people generally don't worry about threats unless they are unmistakably visible -- like seeing the tornado about 3 blocks away. That's just the way we are wired. — Bitter Crank
Not quite it, but thank you for reading enough to get that far. — Jake
Where I live, we just narrowly missed getting hit by a Category 4 hurricane which just ripped through the Gulf of Mexico. — Jake
Maybe that would work. If the framework on which the solar panels were mounted were sufficiently strong and rigid, it could probably be submerged without being damaged by wave action on the bottom. Or, one would float the panels on small lakes or lagoons where wind wouldn't generate huge waves. Floating panels should be look at as a specialty application.
Wind turbines, however, can be located off shore. But they have to be off a shore that gets enough wind. In Minnesota, at least, wind is providing a substantial share of electrical energy. States from MN to TX down the center of the continent generally have good wind. Texas is a leader in wind energy -- surprising, even though there is an exceptionally large amount of hot air in TX. — Bitter Crank
One major problem that is not amenable to a technical solution is population. Not if we want to remain civilized, anyway.
7 billion plus people have the capacity to swamp improvements in food production and fresh water supply by merely continuing to reproduce at moderate levels. What we need to do, in the midterm and long term is reduce the number of people on the planet. That means population attrition, not just in Europe or Japan, but everywhere. — Bitter Crank
Not quite it, but thank you for reading enough to get that far. To quickly summarize my thesis is that scientific progress if pursued without limits will inevitably produce powers which we can't successfully manage. Evidence, we currently have thousands of hair trigger hydrogen bombs aimed down our own throats, hardly a case of successful management. — Jake
The technology exists - the need to apply it is clear. So why is it not applied?
— karl stone
Well, we've not yet resolved key problems with your proposal, as I understand it so far. How do we derive commercial value from petroleum in the ground which forever remains in the ground? How do we put mass solar panels on an ocean subject to repeated storms. Maybe the technology has not been applied simply because it wouldn't work as you describe it? — Jake
No worries on replying, there is no obligation. But sorry, no, you don't get it. Not yet anyway. That's completely normal, especially for science worshipers, no matter how many PhDs they have. — Jake
I think I need more discussion of this, which seems central to your plan. I read your answer to SSU, but don't get it. Or maybe you don't get it either? Not sure. Try again if you want. — Jake
Where I live, we just narrowly missed getting hit by a Category 4 hurricane which just ripped through the Gulf of Mexico. Storms on the ocean are, you know, kinda common. Where exactly do we put the panels that won't experience storms? — Jake
Here's a new report on food and warming, that suggests we need to at least cut back on the meat.
If you don't have time for the academic report, here's the news version. — unenlightened
but in my view, a war for survival is not the way to go.
— karl stone
Hmmm, Odd. If survival is the goal, and there is a real threat to survival, then why wouldn't an all-out effect be the way to go?
If we lose our freedom we will never get it back
— karl stone — Bitter Crank
Throughout American history, "freedom" has always been somewhat illusory. That's probably true everywhere, and it is certainly true here. Deviation from the norm, or clearly expressed dissatisfaction with the norm, usually meant sustained hostility. Luckily for many dissenters of various kinds, there was always frontier territory where one could go, at least until the frontier came to an end in the latter 19th century. Strong challenges to the status quo, like unionism, socialism, Mormonism, abolition, women's suffrage, civil rights for blacks, and so on have been intensely resisted by the central authorities. — Bitter Crank
If the US is going to make it's critical reduction in CO2 and other green house gas emissions, it will be because the central government and centralized corporate powers decided to do it. — Bitter Crank
Hi again Karl,
Well, obviously we're not opposed to clean energy and abundant fresh water. If we confine your post to a purely technical analysis of how to solve purely technical problems, your ideas may be worth considering. I don't really feel qualified to analyze your technical ideas, but they are interesting to examine. — Jake
I would however decline your larger claim that these technical fixes will "save the world". — Jake
We tried to "save the world" by implementing the industrial revolution, and what we accomplished was to replace one set of problems with another set of problems that are arguably larger. We tried to "save the world" with the Manhattan project, and what we accomplished was to put human civilization less than an hour away from destruction in every moment of every day. — Jake
You're trying to apply technical fixes to a problem which is not fundamentally technical. The real problem can be described with a single four letter word. More. — Jake
What the evidence shows is that whatever technical powers we develop we will relentlessly push the envelope in a reckless manner in the endless quest for more, more, and more. And by doing so we continue a process of giving ourselves more power than we can successfully manage. — Jake
Your ideas might give us some breathing room, but if successful they just kick the can down the road a little bit and we'll soon find ourselves once again up against the wall. As example, endless free clean energy would result in us burning through other finite resources at an accelerated rate. The problem gets moved from one box to another box, but the real problem doesn't get addressed, or solved. — Jake
It appears that, like most of our culture, you've bought in to the science "religion" which has as many or more problems than regular religion. — Jake
Yeah my bad, I read the hydrogen part, but didn't think about it writing my post. It was more an example of the type of questions I would have. — ChatteringMonkey
I guess the main issue then might be the cost and efficiency of producing hydrogen. I allways hear that it's not particulary energy efficient, but i'm no expert so... — ChatteringMonkey
The mortgages and the hydrogen production are two seperate things it seems to me, as mortgages can be used to finance whatever renewable energy source. And the market would presumably favor the one that cost the least. — ChatteringMonkey
Though I don't claim to be an expert, I did know that the construction costs were high, and I also know that the production cost itself of nuclear energy are very low. My point was only that the discussion seems more ideological than rational concerning nuclear energy, and that if needed, we should choose nuclear power rather then let CO2 levels rise... until we figure out how to run everything on renewables. But maybe we can allready. — ChatteringMonkey
Mass mobilization, causally speaking, requires a conjunction of opportunities which I feel is not within the reach of many of us. Add to that the fact that most people with the right number of audience aren't bothered by environmental issues. I'm talking about celebrities.
So, it seems to me, those of us who are concerned about the world are left with no choice but to do our stuff at a much lower social stratum e.g. we can raise the awareness of our family or friends or community. We then hope that our efforts spread out from their. — TheMadFool
According to the latest climate report from the UN, we have even less time to do something "to save the world" than we thought: 12 years... — Bitter Crank
Of course we can cut CO2 emissions to practically zero in 12 years (or say 24). When Japan, Germany, Britain, the Soviet Union, and the United States mobilized for WWII, heaven and earth were moved. Tremendous productive forces were employed to build the capacity to wage massive war. We can do it again for CO2 reduction. — Bitter Crank
How?
Convert private auto manufacture to mass transit production.
Start a crash wind turbine and solar cell production program; install widely.
Build large energy storage batteries.
Immediately reduce consumption of goods which are not merely unnecessary, but are useless.
Reorganize life for need rather than profit.
Obviously: end coal and petroleum production. — Bitter Crank
It can be done, but it will almost certainly NOT be done because the short-term costs of saving the planet will cost the rich more money than they can stand losing. It will be necessary to liquidate the wealth of the richest 1%. (Mind, that is liquidate the wealth -- not liquidate the wealthy. Liquidating the wealthy gets too much bad PR.) — Bitter Crank
It's hard to critique the idea, because we would need a lot of numbers and technical details to be able to evaluate it. I mean, i like the idea in theory, but have no idea how feasable it is economically and politically. — ChatteringMonkey
How much would the proces cost, say compared to more conventional means of producing energy? What about night and winter times, is battery technology sufficient to suppliment times when solar energy is low? — ChatteringMonkey
And how do you solve the political issues? Often times people just ignore those, because well unlike the laws of nature, people can just adapt their behaviour, and therefor should... but it never really happens that way. So what about countries that don't have access to the oceans, or that are situated in areas where there is not a lot of reliable solar energy? Do you think it reasonable to expect countries to just get allong, and give away energy to those that need it? — ChatteringMonkey
I think we should go nuclear again, and geothermal. Nuclear can be a temporary solution, not indiffinately ofcourse, but right now CO2 is a far bigger problem then nuclear waste. And maybe in the future we will find better ways of exploiting earth warmth, which is reliable and as good as infinite. In practice, a mix of all possible low carbon energy sources will probably be needed though. — ChatteringMonkey
Those sound like great environmental ideas. You've shown something that hadn't occurred to me...how water, energy, and temperature can be dealt with and helped as part of the same solution method.
It all sounds very well thought-out, and perfectly plausible and possible. — Michael Ossipoff
There's another angle to beef eating which perhaps you haven't fully considered? If we are willing to torture and kill entirely innocent defenseless animals for no better reason than that they taste good, do we have the "psychological infrastructure" necessary to save the world? — Jake
As example, why would a person who smokes be motivated to protect the environment when they are busy knowingly trashing their own most personal environment? — Jake
What if saving the world is, at heart, not really a technical problem but a psychological, moral, emotional problem? — Jake
Another quick interruption.
Having already plugged my sagely wife — Jake
Having already plugged my sagely wife above, I will now shamelessly plug my own "blowharding to save the world" thread, which can be found here. — Jake
While Karl addresses energy and water, my thread addresses another very important component of the world saving project, knowledge.
Karl argues for more knowledge to help manage energy and water resources, a reasonable enough proposition, if one limits the subject to energy and water. There are many challenges before us, and it's very understandable to attempt to leverage the awesome power of knowledge to meet those challenges. — Jake
However, when we 1) add all the knowledge growing projects together, and 2) watch as they feed back upon each other, 3) accelerating the overall pace of knowledge development, 4) we arrive at a different picture, which is.....
The solution is the biggest problem.
I know this to be a hard fact, because when I explain this blowharding theory to my wife while we're making dinner she always says, "Ok honey, I'm sure you're right." See? Proof!!! — Jake
