Actually, in the normal Boeing process, these items are assembled regularly in various stages and made certain to fit (iterative process). The problem is that this is the first time that they have outsourced like this and were not capable of making design adjustments. This was a waterfall process. And the results are just like any waterfall process
had Boeing REALLY cared about fuel, they would be pushing their BWB/X-48. That would have used less in a 380 class craft than a 737 does today. A craft like that would be perfect for the military in Tankers, Cargo, and perhaps b-52 replacements. Likewise, it is the ideal craft for cargo or passenger/cargo mixed. ABout the ONLY big problem with it, is that a number of passengers want the windows (not a big issue with cameras today), And a number of them will not like the feeling in a bank, even a shallow roll. Of course, the smart thing is to store cargo on the outer side and then do a double decker passenger towards the middle. I have little doubt that said aircraft would have PLENTY of sales
They did this for several reasons. The first was to break the unions. The second, and more important, was to help sales. Sadly, America has some of the best knowledge of composites and the RIGHT place for this was here, not elsewhere. At this time, all of the issues that Boeing has is with offshored items (Production for china has been a QUIET NIGHTMARE for Boeing; Many of the parts are of VERY low quality). In fairness, my Wife and a number of friends work for Boeing, so I do get to see info that is not in the main-stream press.
Joe is investigating a number of CORRUPT SUPERIOR FEDERAL JUDGES. And you want to turn over the EVIDENCE to the feds? I say go Joe. Ideally, if he really wants to do this, he should copy those disks and then release the servers. Of course, I would like to believe that is exactly what is going on. The other possibility is that the federal judges have goods on Joe. Of course, so far, many have tried hard to go after joe and over and over he shows that he is law abiding (though tough).
exactly WHY are you so opposed to him? He make jail BE jail and he absolutely PURSUES and sends back illegal aliens (thank god that somebody does) AND he is now chasing down corrupt judges. How is this bad???? Or is there some other issues that you have with him?
Realistically, an aircraft mounted rail gun might serve just as well and be far less complex to deal with (absent the effects on the aircraft of the massive magnetic impulse).
That is almost CERTAINLY coming. However, what I find interesting is that few ppl are taking note of the fact that the mirrors are designed to aim at 90 degrees and CAN point straight overhead. From 50K feet, this laser will be able to take out sats or even a number of military space stations holding kinetic weapons of their own..
WHile I am a BIG believer in Gates(robert, not bill), I think that his idea to kill ABL was dead wrong. If anything, we should be building these faster. These are absolutely ideal for dealing the current and future situation. Now, we just have to learn to quit allowing the specs flowing to other countries.
Just because it is announced does not mean that they know where or for what to look. There are LOADS of US secrets announced and right out in the open. BUT because it is wrapped in half truths, it is not seen for what it is.
It is SUBSIDIZED for you. It is NOT subsidized for Americans. We pay extremely high prices to go to EU schools. In fact, we pay more than it costs. Of course that is normal for many places.
I have not done the Exploratorium, but have done the others. And yes, I would say that they are the best. As such, next time I am in SF, I will have to hit Exploratorium.
Hydrogen is LOADED with all sorts of isses. For starters, it is by far the most inefficient transportation. Even now, batt/caps are the most efficient. Far fare more than oil/CNG/ LPG/ Hydrogen, etc. Their are several issues with electricity. The first is costs. It is too high. But that is coming down. The second is time to charge. That will remain high as long as we are doing batteries. At some pooint, it is very likely that caps will be low costs and have high energy density. There are already 3 solutions in the making for this.
So what about Hydrogen? You have a storage area that has only a slightly higher energy density than what batteries currently have. In addition, you have heavy fuel cells/motor. Obviously, you can simply burn hydrogen, but the weight and space and complexity of an engine is again more than battery/motor.
Finally, the above ignores the total lose of efficincy involved in making hydrogen and transporting it. In the end, electricity is the only answer that will take over engines.
For the most part, yes. I object to those pushing hydrogen as being the end all, when in reality we are decades away from having so many of the minor issues, let alone some of the major ones, solved. For example, right now, somewhere between 90-100% of all commercially available H2 is by stripping it from hydrocarbons. What happens to the C? it is released as CO2. IOW, hydrogen does nothing to solve the carbon issue. So, lets assume that we want to have less oil being brought into the west. Then our energy use climbs even higher. It will actually use MORE oil/CNG to switch to hydrogen. Even if we solve all of the major issues, it will still be more efficient to use batteries/capacitors. The reason is that all of the means to generate hydrogen will involve a lot of energy. Hydrogen CAN be made more efficient than oil/cng, but it will never be more efficient or less costly than electricity.
Actually, there is much more than that. For starters, nearly all of the current hydrogen comes from stripping it from Oil or CNG. This is funny, because you take it off and then release the CO2 that was created. Yet, it would have been far more efficient to flat out burn it.
The other approach is obviously to split it from water. BUT, this is VERY energy intensive, and will remain, there is no real way around this; you have to break the bonds. Obviously as you point out is the issue of the transportation and storage. You have both ground storage as well as storage in the vehicle. There is no easy or energy cheap way to do either of these. In the end, it is currently FAR FAR cheaper to take that initial electricity, send it over a poor wire, store it in a lead acid battery and then use a 98% efficieny motor. Basically, all of those pushing Hydrogen are not just ignoring state of the art, but simple physics.
First, I doubt that you will have a small fusion reactor in our cars anytime soon.
Second, Hydrogen, currently, has higher energy density, BUT has issues with storage, as well as usage (motors are very inefficient and fuel cells are a LONG ways off). LONG before hydrogen issues are solved, batteries will have a higher energy density (assuming that hydrogen can not be compressed infinitly).
How exactly did we obtain that clean supply of hydrogen? And I am talking in terms of TODAY as well as say another 20 years, rather than saying by fusion power? If you look at the efficiency of that cycle, it is, and will remain, inefficient. At least until we can obtain hydrogen for free, which is not likely to happen.
So, can wind, geo-thermal, solar, Coal, nukes, etc. And ALL of those items are needed to generate the energy to separate hydrogen from water (or even a fossil fuel). AND the total cycle of electricty->transportation->battery->motor is STILL far more efficient than is electricity->(fossilfuel|water)->hydrogen->transportation->various storage->(fuel cell|engine|etc).
We are using SMALL amounts of alcohols in our fuels to oxygenate the burning. Problem comes in when it is the primary form of fuel. Then you will ALWAYS have partial burning. As you point out, ethanols are converted into a number of side products which includes aldahydes. In small amounts, overall not a big deal (though still not great). But in large amounts These are ABSOLUTELY WICKED.
I plan on creating a bee suit to let 300 pound people fly.
Oh, good. I think that has a MUCH better chance of happening then our moving towards a hydrogen economy. The simple fact is, that hydrogen is actually WORSE than any other options. Even right now, current in production Batteries are already better than what hydrogen can or ever will do.
The US, simply, can't compete against much of the rest of the world at most of the traditional industries. Our quality of life is too high and would have to nose-dive to make us competitive. The places that we've always dominated, since WWII when we really first developed a middle class with above average quality of life, have been high-tech such as computers, pharmaceuticals, materials science, etc. As we move forward, it's inevitable that other countries will start to catch up in some of those places and out population will continue to grow.
This is absolutely FALSE. The reason why we are losing ground with China and India is solely because they both have their money tied to the dollar, and also have trade barriers against all western nations. That has to stop. China was suppose to free their money and drop trade barriers in 2002 as part of obtaining MFN from America, but have renegged on the trade barriers (in fact, says that it will not drop them for another DECADE) and did a fake opening of their money. It is in a "basket tied to various moneys". Problem is that while China has improved their economy with double digit growth vs, below 5% for most of the west, their money rose less than 17%. In fact, it has stalled since Sept. According to nearly all economists, it should have risen by 300-500%. In addition, India has their money FIXED against the dollar, along with trade barriers. Finally, both India and China are heavy heavy heavy polluters in terms of their land. What is needed is for them to have to use the same or better equipment as even the least of the west (which sadly IS America WRT CO2, though we are one of the better ones in terms of other pollution).
Finally, we need to automate more. America at one time was the LEADER in automation, in terms of developing it as well as implementing it. Sadly, since reagan gave amnesty to illegals, we have quit automating. Instead, we count on "low cost" illegal labor. That has been destroying our ability to compete since we pay the illegals less, but it is still more than other nations pay (otherwise, they would leave here). The neo-cons of the last decade allowed in more, and the dems now want to continue to allow this nightmare.
Until we address these multiple issues, there will continue to be unfair trade. In fact, it will get worse because of our attempt to address our CO2 emissions. That will only encourage nations like China, India, Brazil, and even Mexico to pollute more to grab as many jobs as possible (similar to what W did to EU). Instead, the west needs to do a tax on ALL GOODS based on where they originate from. It needs to be implemented slowly (say 4 years) to give countries time to adjust. Thankfully, it sounds like EU is actually considering it, which is really needed. Time for EU to lead.
what are the other costs for this new material? It is possible that this will take a lot more energy.
One odd idea for cement is to start using solar to make it. I would think it should be possible for using a solar kiln to do the heating of this. Yes, it will not solve the breaking up, but, the true energy intense part is the heating.
I would think that sidewalks and minor side roads would be the place to start. If EU is going to start this, then perhaps we should order some of this and put it into various places (none structural) to see how it lasts. In fact, just thinking about it, it MIGHT actually improve the roads. It would slowly gain weight which MIGHT also strengthen bonds in it, though I notice that they have said NOTHING about that. I would think that if it did get stronger, then they would say something. Regardless, if this is cheaper, it would be great on sidewalks.

how do they handle things when you find out that you have the next Mao Zedong or Stalin?

to get news in such a way that the FBI does not know about it.

Actually, back in the mid 60s (before Exploratorium was built), Chicago had lots of hands-on stuff.

No. There are ROADSTERS on the road, not the sedan. And like the sedan, ppl were buying it before even the prototype was produced.
