AI Thread Summary
The discussion centers on developing a comprehensive plan to address the US energy crisis, emphasizing the need to define specific problems such as pollution from coal, rising demand outpacing supply, foreign oil dependence, and high costs. A proposed solution involves a 30-year, multi-phase approach that includes constructing modern nuclear power plants, heavily funding alternative energy research, and implementing immediate regulations to reduce pollution. The plan outlines a significant investment, potentially $3 trillion over 30 years, but promises long-term benefits like reduced pollution, increased energy capacity, and lower costs. Participants also highlight the importance of political will and public awareness in driving these changes. Ultimately, the conversation underscores the urgency of addressing energy issues through innovative and practical solutions.

It seems to me that, especially given the recent short lived and failed attempts of actual wave/tide energy projects, the interesting engineering results lie not in demonstrating the energy output of a given scheme, no matter how elegant and clever. Instead, the interesting results would be in calculating the inevitably high shears and moments on the structure, the chemical affects from salt water, and demonstrating how such a design can tolerate these adverse impacts over long periods of time, using economically viable construction techniques.

The chemical affects from salt water -Now we live in the age of polyvinylchloride PVC
The maximum pressure can not exceed 10 bars, which corresponds to a pressure of water at home. Thus, for most of the elements you can use PVC.


In addition, all ships in the world with regóły swim in salt water and somehow cope.

Also, tanks can be built on the very edge of the sea, przz what can be designed with a smaller safety factor, because if failure of the water will run down a short path to the sea. If there will not allow people to stay, nothing anyone can, even during high-accident

And started all of my oscillating dynamo in which the oscillations are due to the use of unidirectional semiconductor diode meets
Here the role of the diode valve to go with a spring water valves .
Now you can see the very first ideas oscillatory dynamo:

Is the device designed to be rigidly attached to the sea floor? If so what is the maximum depth? What's roughly the maximum sheer moment on the main float-piston shaft? What material must be used to withstand that sheer?

In addition, all ships in the world with regóły swim in salt water and somehow cope.
Do you think all the ocean going ship hulls could also be made from PVC?

The 'somehow' includes drydocking ships and resurfacing their hulls, which also mostly don't have exposed moving parts. How easy is that to do (remove and service) with this device that is apparently rigidly anchored to the the sea floor? That degree of difficulty is going to matter, as the device's maintenance costs must be balanced against its output. From some of the wave devices listed above in this thread and on http://en.wikipedia.org/wiki/Wave_power#Modern_technology", a single wave-float pump might be on the order of 100KW with at most a capacity factor of ~40%. Such a device produces approximately $32K worth of electricity per year, and its annual maintenance budget (removal and towed back to shore? resurfaced on location?) must be a fraction of that output.

You may need to ask the Japanese how they have managed to corrosion?

If you want answers to all these questions, you probably need to open a new new academic department.And then you can better edit the Wikipedia .

Until then, with the same idea as myself two years ago, came the Swiss firm, and produced a mobile phone, you do not have to be loaded.
Just hang on a tree growing near you some of these phones and you will have when it will be a little nod from the wind electricity for household

See that's the point, the significance of that article is in the saltwater aspect; there's nothing new about fresh water pumped storage. That pumped storage facility is 31 MW per pump; i.e. it has a relatively high power density. Thus they can afford an expensive corrosion prevention program: stainless or other special steels, active cathodic protection from an external electrical source, and possibly a full time maintenance crew continuously resurfacing the sea side of the system, just as is done for bridges like San Francisco's Golden Gate. These wave energy systems exhibit low power density per device; i.e. it appears some major innovation is required to economically maintain a salt water offshore 31 KW device. Perhaps it can be done, I don't know; certainly the problem is not trivial.

That's why these are the interesting questions(dealing with the marine environment).

Probably English lit, fiction that is, would be best. :biggrin:

Seriously, probably depends on the actual type. Include chemical engineering and molecular biology in the list for the biofuels, and materials science might also be a useful gateway for solar PV. Many of the oil and gas companies seem to be betting large amounts on renewables, so even entering one of them with a petroleum (or chemical) degree and then switching over might be a plan.

The ironic thing about conservation approaches is that they defy the inverse logic of modernization where technology increases energy-efficiency while consumption-culture intensifies to deplete the surplus. To conserve at the consumption level means moving in the direction of so-called "primitive" people who often use no vehicle, have no climate control besides fire when it's cold, rely very little on commodity shipping, etc. These "primitive" cultures are more energy efficient but they defy the western sense of entitlement to consume more in reward for progress.

The interesting sequel to this discussion would occur after people in the developed world would lower their per capital consumption to match those in the developing world. At that point, we could start talking about ways to increase the energy-efficiency of those processes that supplied large numbers of people with certain basic commodities. That would, in effect, achieve a level of global energy consumption that would be completely sustainable with renewable sources.

For example, a clothing factory could be streamlined by changing clothing designs. Furniture production or building architecture could be streamlined by designing plans that relied on less processed wood and other materials. Eventually, the biggest issue would be heating in cold climates, I believe. This would be solved by creating relatively compact spaces of rest and clothing that would allow people to keep warm with a moderate amount of physical activity. Another option might be for people to migrate by foot each fall to warmer climates for the winter. That may sound ridiculous, but if it could be made economically feasible, it would reduce energy consumption to practically nothing.

Wind Turbine Projects Run Into Resistance
http://www.nytimes.com/2010/08/27/business/energy-environment/27radar.htm

Moving turbine blades can be indistinguishable from airplanes on many radar systems, and they can even cause blackout zones in which planes disappear from radar entirely. Clusters of wind turbines, which can reach as high as 400 feet, look very similar to storm activity on weather radar, making it harder for air traffic controllers to give accurate weather information to pilots.

Although the military says no serious incidents have yet occurred because of the interference, the wind turbines pose an unacceptable risk to training, testing and national security in certain regions, Dr. Dorothy Robyn, deputy under secretary of defense, recently told a House Armed Services subcommittee.
. . . .
Beware of unintended consequences!

Sounds like a bunch of right-wing nonsense to me. All of the issues mentioned can be easily overcome by just knowing where the wind turbines are. This sounds a lot like the "We need to stop making hybrid cars because blind people can't hear them" argument.

Very inspirational speech. CO2=PxSxExC: nice clarity. The only thing I wonder is why do these kind of speeches always build up to suggesting more spending? Why doesn't anyone ever base their visions of progress on the idea that necessity will breed innovation? It seems to me that every time loads of money get thrown at change, the result is more spending on the status quo. How much money was invested in hydrogen and electric cars before it all culminated in cash4clunkers? How much has been spent on improving the energy efficiency of buildings and what has changed in terms of climate control practices? I would have expected many elegant designs for open-air work and consumption spaces. I would have expected to see more light vehicles with sun/rain canopies but no a/c. I would have expected to see cooperation between employers and city planners to move employers and employees closer together to promote pedestrian commuting. How much stimulus money does it take to initiate these kinds of innovations? Or is the truth that the stimulus was only ever intended to maintain cash flows at levels that would preserve the status quo of paying current utility costs, maintaining current machinery, paying off current mortgages, and renovating current infrastructure for current commuting patterns?

Never heard of a U-238 reactor before.

I'll check it out and get back to you.

(ten seconds later)

Oops. Never mind. Wiki says it's true:

U-238 can, however, be used as a source material for creating plutonium-239, which can in turn be used as nuclear fuel. Breeder reactors carry out such a process of transmutation to convert the fertile isotope U-238 into fissile Pu-239. It has been estimated that there is anywhere from 10,000 to five billion years worth of U-238 for use in these power plants. Breeder technology has been used in several experimental nuclear reactors.

I hate that Gates guy.

I hope his kids kick him in the shins when he gets older, or twist his nipples real hard when he's sleeping. :devil:

I would love to see him stand there and talk about zero emissions and then say that he's going to take the first step by not letting a penny of his fortune get into anyone's hands who uses any fossil fuel in any way. See if there's any applause after he says that.

Five million dollars!

Now that, I hate way more than Gates.

Gates is more a jealous kind of hate. I was a ML coder back in his day. Those were the days. I think I wrote over 2000 programs in a 3 year period.

Actually, given a year, and about $100k, I could kick http://www.edison2.com/" 's derriere too. Maybe I hate them both equally.

The Opinion Pages
...
Beijing just announced that it was providing $15 billion in seed money for the country’s leading auto and battery companies to create an electric car industry, starting in 20 pilot cities. In essence, China Inc. just named its dream team of 16-state-owned enterprises to move China off oil and into the next industrial growth engine: electric cars.
...
Europe is using $7-a-gallon gasoline to stimulate the market for electric cars; China is using $5-a-gallon and naming electric cars as one of the industrial pillars for its five-year growth plan. And America? President Obama has directed stimulus money at electric cars, but he is unwilling to do the one thing that would create the sustained consumer pull required to grow an electric car industry here: raise taxes on gasoline.


Bill Clinton mentioned something similar regarding this, which I think I didn't quite relay properly the other day, and had https://www.physicsforums.com/showpost.php?p=2896073&postcount=122":

Bill Clinton said:
...the rest of the stimulus money that's going to be spent now, it's all the clean energy money. And we can dominate that, or be left in the dust,...
China spent twice as much money as we did last year on clean energy technology.

There's a good reason why Obama hasn't raised taxes on gas, and its because people would go absolutely ape @#$% over it. Just look at how much aggression has been created by the Bush tax cuts ending. If Obama was to enforce an increase cost in gasoline the right wing republicans along with that whole "tea party" movement would tear down the white house.

I think its a very good idea though. Increase the cost of gasoline to help fund alternative energy development and maybe do it with providing a tax waiver for the poor. To bad us Americans don't know what's good for us.

Either we do it strategically, in a controlled manner, to foster alternatives and end our reliance on oil, or we wait until the market does it for us, without controls, and live with the consequences of an avoidable disaster.

It might fly with an exact revenue match in income tax reduction, where it could be sold with the pitch - save gas and you are ahead of where you were before the tax. Would have flown already I expect, except for the exceptional impact on large, sparsely populated states where its nothing to drive your F150 50mi to work every day.

Why can't you just invent a better alternative to compete against gasoline powered transportation, rather than raise taxes to "research alternatives"?

Why can't we just invent a perpetual motion machine that makes more energy than it consumes. If it were possible to wave a magic wand and instantly create an entirely new eco-friendly infrastructure out of no where that was just as economical as gasoline then there wouldn't be an energy crisis in the first place.

Which forms of alternative energy specifically do you think need large amounts of funding from the government to make progress? It seems to me that the limitation these days isn't funding, but I could be wrong.

OmCheeto said:

I don't think the problem is funding or size, it's just that fundamental technology hasn't been found that can rival the specific stored energy of petroleum products. If electric cars existed that had a 300 mile range and charged in a few minutes, gas wouldn't stand a chance...

OmCheeto said:

The solution is not political, its physical. The secret is to be able to store and transport existing clean energy (Solar, Wind, Hydroelectric, etc.) in a sustainable format.

Not particularly difficult; the same problem arises out of the breeder reactor program that is supposed to come on-line in around 2030 and solutions have been proposed and alternates have been created.

It's such a joke to listen to people talk about investing in new infrastructure to facilitate conservation. Bicycles are much smaller than cars so exponentially more bicycle traffic can fit on existing roads if significant numbers of drivers converted their lifestyles to biking and walking. The problem isn't the infrastructure, it's the unwillingness of individuals to change their everyday behaviors. Then, of course, you get into all the institutional barriers like why people can't just change jobs to one closer to their house or why employers and employees can't restructure in a way that has them close enough to each other to pedestrian-commute.

It is because no one wants to consider pursuing these kinds of solutions that all the talk about expensive government solutions emerges. Basically the expense and the difficulty of achieving political consensus work as barriers to prevent anyone from having to change. They voted for change and what they got was insulation against having to change, which may have been what they secretly wanted all along.

Frankly, I don't know how utility companies became private, nor do I care. I don't really see how it relates to infrastructure.

I was listening to the radio the other day, and a young gentleman put it in much better words than I could.

Imagine if everything were private. Gas, electricity, sewer, roads.
Imagine 20 different companies, from the above 4 fields, all after your money.
You'd have 20 separate sewer lines running to your house, 20 separate gas lines, 20 electric lines. And how are you going to fit 20 roads in the space of one road? Stack them? All so we can chose the cheapest, or most reliable, or the least rat infested?

NO! We don't need to privatize the whole world to make it a better place, given your apparent assumption that privatization will solve everything.
If no one wants to invest in it, it could be it's not that great of an idea to begin with... However as it is, there is a LOT of private investing happening in alternative energy research.
There is also a LOT more public investing happening in alternative energy research. Unfortunately, it's public investing by other countries, competing against our "free" market companies. We can sit around with our thumbs you know where, waiting for our companies to do the right thing in the right way, while foreign companies are getting massive government subsidies, getting ready to ramp up production in, you guessed it, alternative energy.

hmmm... Guess who loses? We do.

There are only a few basic concepts in economics that I've ever thought worthy of devoting brain cells to, one of them is the theory of the economies of scale. If the YenWonYuan Corporation is 100 times bigger than Oosa Corporation, guess who's going to determine prices. Guess who's going to have the most jobs.

Waiting around for market may have worked in the past, but we're not in the past anymore. And wagging your finger at the Chinese Government for being unfair by dumping billions into their upstart companies, is not going to make them stop.

Just one example:
But A123 has another problem on its hands. A pair of giant lithium-ion battery makers -- Japan's Panasonic and Korea's Samsung -- has recently stated plans to radically boost spending to retain industry dominance. They also plan to cut prices to pursue market share, and that's a battle that relatively tiny A123 is ill-equipped to fight. So even as the company looks set to sharply boost sales in 2011 and 2012, gross profit margins may be so low that the company's operating losses fail to shrink. The key for a turnaround in this stock is a path to eventual profits. And until investors can see that path, shares are unlikely to rebound much.
And they didn't even mention the Chinese companies.

Ugh! And I never thought I'd quote Bill Gates:
http://news.cnet.com/8301-11128_3-20007344-54.html
Invest a minimum of $16 billion a year on clean energy. The group said that the U.S. currently spends $16 billion overseas on foreign fuel every 16 days.
But he's right. While we're sitting here, hundreds of billions of dollars are being flushed overseas.

I don't like that you think it's a good thing that the federal government is great at investing in things no one else will; in fact it seems to me this is one of the fundamental problems with the federal gov't- they are rarely subject to cost-benefit analysis.

Well, I can somewhat agree with you here. I had a post deleted quite a few months ago. It was fairly extensive, and consumed probably 12 hours of research. It was a severe criticism of a pair of academics who, based on a government installed solar project, determined that solar energy was not financially viable. I'll not go into the details, except that yes, the project was incredibly expensive, and would never provide a return on investment.

I disagree, but only because I live ~12 miles from work, in an environment that is not conducive to bicycling 10 months out of the year. And relocate? Do you want everyone to sell and buy a different house every time they get a new job? Or are you talking only about renters?

I know that we all bring our preconditioned prejudices to these conversations, but a solution to the energy crisis needs to include solutions for everyone, not just me and you.

Personally, I'm pursuing an enclosed vehicle that gets 300 mpg* equivalent, with a range of around 30 miles. And that doesn't cost $40,000. I mean really, that's twice what I paid for my house!

*Yes. I know. That's 100 watt hours per mile. But I'm a firm believer in the Kobayashi Maru: When it's impossible to win, cheat. :)

This can be a very negative board.

Wouldn't it work better, if in the brainstorming phase, if we focussed on creating ideas and only offered objections when the original poster was asking for that kind of feedback.

There is enough negativity in experimental results that speculative negativity is just excess.

Government projects have been very successful (Interstate Highway System) and so have private ventures (The Pennsylvania Railroad). Is this really the forum to determine the political answers? Shouldn't we explore the scientific means?

Scientific means? Those are easy. It's everything outside of the engineering field that gets sticky. Going through the last 41 pages of this thread will probably provide you with the "engineering" answer to the original order: "YOU! Fix the US Energy Crisis"

To continue, in response to our seemingly off topic discussion of the last few days:

I mentioned "Systems Science" a while back and was flabbergasted at https://www.physicsforums.com/showpost.php?p=2559571&postcount=3". (I didn't understand a word, and hence, I felt I wasn't qualified to say a word about the topic to which I was referring to. "Could Aperion be a systems scientist?")

Systems Science, in my little mind, related only to the simple idea that everything is interconnected. Nothing can be ignored. Everything must be discussed. I was first exposed to it in the movie Mindwalk, by Bernt and Fridjof Kapra. A movie about, well, it's very, very, boring. You'll have to watch it for yourself. I've a Vhs copy that I nearly wore out.

Many problems involve so many aspects(social, political, scientific, economic), that you cannot help but to break the rules if you want to really solve a problem.

Bicycle solutions are not pursued because they are not equivalent to motor vehicles across dozens of different obvious metrics, regardless of 'lifestyle' choice.

Well, considering that the real estate market is overflowing with toxic properties and a glut of excess housing, it really doesn't seem like it would take much of an infrastructural investment to coordinate people being able to change residences to live closer to work.

I know that we all bring our preconditioned prejudices to these conversations, but a solution to the energy crisis needs to include solutions for everyone, not just me and you.
Ultimately the solution for the vast majority of people is going to have to involve living most of their lives in a relatively dense urban environment. The question is how to organize the economy in such a way that facilitates sustainable lifestyles in relatively dense cities.

Personally, I'm pursuing an enclosed vehicle that gets 300 mpg* equivalent, with a range of around 30 miles. And that doesn't cost $40,000. I mean really, that's twice what I paid for my house!
You paid $20k for a house? What a bargain. Enclosed vehicles the size of bicycles are an ideal solution because they get good energy-distance efficiency and they are small enough to allow more vehicles on existing roads without widening them. The problem is that they're just not going to supplant large heavy vehicles overnight. So it makes far more sense to implement mobility-culture reforms that help people transition to pedestrian/bicycle living for the majority of their life activities and reserve personal car transit for weekend getaways once in a while and large-item purchases.

*Yes. I know. That's 100 watt hours per mile. But I'm a firm believer in the Kobayashi Maru: When it's impossible to win, cheat. :)

I think an average person generates about 40 watts and can bike @15mph, so if you divide 40 watt-hours by 15, you get a little less than 3 watt-hours per mile. Beam me up, Scotty.

It's always the same thing whenever I mention bicycling or walking as a solution to energy crisis. People say that bikes are inferior to cars or they live too far from work, etc. But all those obstacles are not necessity but luxury. If there was absolutely no gasoline available, you would quickly see people adjust their lifestyle patterns to walk or bike. They might complain that biking and walking are inferior to driving "across dozens of different obvious metrics," but they would do it because they would have no choice. Then, they would continue to innovate the local economy to make living within a small geographic area increasingly more pleasant.

And guess what, doing this would require relatively little if any government investment in infrastructure or otherwise. People would just reform existing infrastructure and building usage to accommodate large-scale reliance on human-powered transit.

Indeed, I might consider biking when roads are sufficiently safe (free of cars) and there are locker rooms in every office buildings/workplace. But it is an immense undertaking to reform existing infrastructure, and if a politician were to propose this today, he would not get any votes.

I agree with you though. Humans can adapt, but for the moment, they (we) don't feel sufficiently threatened to make such radical changes in lifestyle.

Which is why this thread is somewhat superfluous. We talk about fixing the 'energy crisis' but in reality public denial of the crisis is the driving political-economic sentiment. If people were serious about reducing energy-usage, the kinds of reforms/restructuring you mention would not seem like such an immense undertaking.

What is more difficult, building locker-rooms or other bicycle-commuting friendly facilities in areas where people work or building entire rail systems to expand public transit, as has been promoted as a reasonable public investment? Clearly building rail-systems, electric vehicles and charging stations, etc. requires more investment but people just think that the investment will stimulate the economy, which will in turn sustain the high energy-consumption economy that makes them comfortable.

What is also needed are technologically simple solutions for climate-control systems. Roofs can be used to generate solar heat, for example, but some kind of cheap effective method for enclosing them with transparent material is needed. Glassing in a roof is expensive but if some kind of plastic was available that would resist deforming due to the heat, this plastic could be stretched over entire roofs to create a heat-capture space and indoor air could be circulated through the enclosed roof area (probably some air-filtering would be a good idea with this).

As for cooling in hot months, fans provide air movement that make the indoor air feel cooler than static air at the same temperature. Fans use less energy than air-conditioning.

The problem is that all such conservation measures require humans to adjust their comfort levels, which requires they endure temporary discomfort during the adjustment period. Ultimately it is avoidance of discomfort that is driving most energy-waste. It is ironic that we try to come up with elaborate technical/engineering solutions for a problem that is essentially psychological and social-cultural.

That is all hand waiving, which I note you do while considering the assumptions about the status quo 'such a joke'. You are essentially calling for a back to nature, log cabins and grow your own food plan. Do you really imagine the world hasn't heard endless (and thoughtless) calls of this kind since the beginning of the industrial age? If you want to add to the conversation, take the time to show in at least one (challenging) detail how migrating a modern society mostly to bicycle transportation could work for 300 million people of men, women and children, the sick and the infirm, spread out over a continent 3000 miles across.

It's also "such a joke" that you make reference to the "sick and infirm," as if the difficulty these people have with human-powered mobility should automatically exclude healthy, able-bodied people from carrying their own healthy bodies around. Really the size of the continent or the number of people you include in the population doesn't matter. How many people got around without cars in China until very recently? Were they able to do that because of the small size of the physical geography or population?

I'm not saying that no one should ever use a car or public transit for anything. I'm not saying anyone has to live in a log cabin or grow their own food, although I think that would be good for other reasons. Mainly I'm pointing out that because there is resistance to considering energy-conservation strategies that involve culture/lifestyle reforms/changes, people make this energy-crisis more complex and expensive than it really needs to be. The simple fact is that there are numerous ways to modify the way you live and work that reduce energy-consumption. The need for everyone to conform to the same lifestyle is not a valid 'need' at all but a luxury that people have grown accustomed to. Just because your neighbor has air-conditioning, drives a car everywhere all the time, and keeps his voluminous house warm enough in the winter to lounge around in his underwear doesn't mean that everyone else has to aspire to that as well, does it?

Btw, it is so typical to be attacked like this whenever suggesting simple conservation reforms. Could it be that such attacks are the reason energy-conservation never gets off the ground to start with?

Ah, there's case. I asked you above to explore such a case, as this is an Engineering forum. In China, before a significant motor vehicle presence, along with the millions of bicycles China also had
I don't see a modern life expectancy and income sufficient to live in a single family dwelling as "luxuries." Inexpensive mobility for a family, that enables http://en.wikipedia.org/wiki/Division_of_labour" r is visibly a contributor to the economic productivity that makes these possible.

Btw, it is so typical to be attacked like this whenever suggesting simple conservation reforms.
I'm attacking the material in your posts in this line, but apparently insufficiently, so here's some more.

This is the G. Engineering forum, you are aware of the guidelines. Yet instead of offering something akin to a quantitative analysis, you would make this into the navel gazing forum by offering strawmen and loading your posts with smug pronouncements, e.g. "this thread is somewhat superfluous", "It's such a joke to listen to people talk", "And guess what", "people just think", topped off by "People would just reform" when they do as you pronounce, without bothering with a single reference. Please take it all elsewhere.

BTW, I bike 24 miles a day, family commitments permitting.

I still think it's a huge undertaking.

Solar panels may be able to heat homes in some countries, but up here in Canada, it can not be taken seriously. Not only it can't possibly provide enough heat (from a regular sized-roof), but no one is going to want to shovel snow off a roof-top after the typical storm we get a few times a year. I'm counting on hydro and nuclear for this.

Yes. Although perhaps the hot air produced by air conditioning could be used to heat water, instead of being wasted.

I suppose we need to attack the problem on all fronts.
