I just don't see it being real useful to try and harvest waste heat from an ICE or turbine.

    Most energy loss in an ICE is from Air Compression and valvetrain loss?

    I would think that most of it would be because combustion is a woefully inefficient way of raising air pressure. Air compression should not be causing too much loss because that energy can be largely recovered on the power stroke. (except for ring blow-by (minimal) and compression-related-heat soaking into the cyl. wall) Valvetrain loss should only be due to cam friction (which is reduced by oil), as the energy required to compress the valve springs should be mostly returned when the valves are released.

  7. I'm having trouble following you on US Courts Consider Legality of Laptop Inspection · · Score: 1

    I'm a little confused why you think that an international border is not different from an internal one... They are fundamentally different entities. There are of course the obvious legal distinctions: namely the Feds have exclusive jurisdiction over the national border. Not so state and local ones.

    The first thing that comes to mind is that the U.S. government has no direct control over what happens outside of the border. Without inspections, there is simply no reasonable way to ensure that illegal persons and/or goods do not enter the country. There is no visibility as to where those people or goods came from. Within the country, there is the law enforcement apparatus of the U.S. tasked to capture criminals, prevent the manufacture of contraband, etc. Since the U.S. cannot stop the manufacture of contraband abroad, how exactly do you propose that it be prevented from entering the country? One shipping container looks just like another. Without ID checks, how do you ensure that those crossing the border are not known enemies? Inside the U.S., the IRS can obtain probable cause for tax problems if your return doesn't match the W-2 your employer sent in. How is Customs supposed to verify you are paying proper duty on your goods without examining them? If probable cause were required, where would it come from? Again, one shipping container looks just like another.

    The control of the national border is a legitimate government interest, and searches and ID checks are a reasonable way of exercising it.

    I also don't get where you get the idea that the 4th amendment is ignored at the border. You do have those protections, they just are not nearly as strong. Your possessions cannot be permanently seized "just because", you are not subject to a body-cavity search as part of a random check. You are protected against "unreasonable" search and seizure, but reasonableness is held to a different standard to fit the circumstances.

    At the border of the country, searches that would be unreasonable in downtown Chicago become reasonable. The random (and not so random) inspections that are carried out are pretty much the only way (short of extensive operations on foreign soil) that Customs and Immigration laws could possibly be enforced.

    Part of the reasonableness standard is determining if the same legitimate ends (securing the border of the country) can be achieved through less intrusive means. What is your less-intrusive alternative to the inspection of people, possessions, and goods at the border?

    Based on that logic, the 4th amendment would prevent the US government from doing anything about an invading army once the invading army was completely across the border into the US.

    Once an invading army is through Customs, how would you stop them? Up until the point the guns come out, what is your less-invasive alternative to stopping them at the border through simple ID and cargo checks? The 4th amendment affords them full protection once they are through the border. They can drive throughout the country at will, as long as those weapons stay out of plain sight.

  8. Again, you confuse reasonable with useful on US Courts Consider Legality of Laptop Inspection · · Score: 1

    The question posed is: Does the security of air travel, as currently implemented, constitute "reasonable" search under the 4th amendment? The question is NOT: "Is air security effective in reducing terrorism?"

    Attempting to protect citizens during a particularly vulnerable time (there is no escape from a violent incident several miles above the ground) is considered by the courts to be a legitimate government interest. Moreover, the searches, as currently implemented, are considered to be a "reasonable" expression of that interest. That's it when it comes to legality.

    Are searches done in a useful manner? Are they a waste of resources that would be better spent elsewhere? Is there any point? All those are policy questions, which is beyond the scope of the legality of the measures. An "unreasonable" waste of resources does not make the searches "unreasonable" exercises of government power.

    I will be the first to admit that aviation security in the U.S. is a poorly done pile of crap. It is makes swiss cheese look as solid as a brick of lead.

    However, the legality of a bag search is not affected by how neat or nice they are about it, or if it is done in your presence. (The lack of witnesses might affect the admissibility of any criminal evidence found, but that is another matter.) The legality of a bag search is not affected by the fact that there are oodles of other ways to do very bad things to an aircraft.

    Also, the only clothing one is required to remove in public in a TSA line is your coat and shoes. (This was not always the case, but a few nasty incidents changed that quickly.) You are allowed to request that a search of your bags or your person be done in private.

    My point is that a search of your bags prior to them being loaded onto an aircraft is a reasonable exercise of government power, and therefore legal.

    It appears the search at Customs in the original article was a random search, and it appears to have worked. (Certainly they do not inspect the contents of every laptop entering the country.)

    By the way, the Lockerbie bombing was caused by checked luggage. All international luggage from the U.S. was either scanned/searched or subject to passenger-matching shortly afterwards. (meaning, if you didn't get on the plane, your luggage had to be pulled) This practice was merely extended to Domestic luggage after 9/11. As another related side note, there is actually no requirement to search or X-Ray all luggage. However, since the only legal alternative for the airlines is to passenger-match every single bag, which would delay the aircraft terribly in the event of a passenger missing their flight. This was done after 9/11 prior to the whole TSA apparatus being in place, but no airline would choose it.

    Here's the problem. Any argument for controlling international borders also applies to state and local borders. If you can keep someone or something out of a country then you can also keep it out of a state, city or neighborhood.

    Heh. You got me there. However, I should point out that there is no nation currently on earth that does not exercise some measure of control over its borders.

Even at the time of the Constitution, there were nations that realized slavery was a bad idea, and that women should have equal rights.

  11. "resonable" is admittedly a slippery concept on US Courts Consider Legality of Laptop Inspection · · Score: 1

    Your luggage is subject to search on domestic flights for good and sufficient reasons. The ability to smuggle a bomb onboard an aircraft in checked luggage was an obvious and stupid hole in airline security. (There are still plenty of obvious and stupid holes left, but this is certainly a start.)

    This is all legal because it is considered to be a reasonable exercise of power for the government to protect its citizens in this manner. Your carry-on luggage and your clothing have been subject to search for decades, why should checked luggage be any different?

    However, it would likely be considered unreasonable for a TSA agent to demand a search through your laptop hard drive, since the contents of your hard drive have no bearing on the safety of an aircraft.

    At the border, OTOH, the customs agents are charged with (among other things) the preventing the importation of contraband into the U.S. Illegal materials are illegal whether they be in a magazine or contained on a laptop hard drive.

    What separates a "reasonable" search from an "unreasonable" one? I believe in the legal world, a "reasonable" search would be one that narrowly serves a legitimate government interest. Random searches of people on the street "just because" are unreasonable because they are too broad. Searching those that would board an aircraft specifically for items that could cause harm to those on board the plane is sufficiently narrow to be "reasonable".

    What it really comes down to is that few American travel internationally so, from a purely selfish perspective, Americans are OK with border searches but because they don't expect to be affected personally while they oppose other searches (e.g. house searches) that would affect them personally.

    It has nothing to do with the complacency or acceptance of Americans for laws that do not affect them. It has to do with the fact that border searches, are, in fact, a reasonable exercise of power by the government of a sovereign nation. All nations have the power to control the people and objects that cross its borders. Period.

    Is the request that all those entering the country show valid identification also unreasonable? Under your logic, it would seem to be.

  13. The 4th does not apply to border searches on US Courts Consider Legality of Laptop Inspection · · Score: 5, Informative

    The 4th amendment does not apply to searches at the border, and it never has. Throughout modern history, every country in the world (the U.S. included) has reserved the right to search anything and everything entering the country, save diplomatic pouches.

    The 4th amendment only covers "unreasonable" search and seizure. Border searches are considered reasonable, and therefore require no warrant. This was formally codified by the 1st Congress (thank you Findlaw), who could be assumed to know the intentions of the founding fathers. More intrusive operations over and above a cursory search (such as X-Rays, or I supposed computer checks) only require "reasonable suspicion", as opposed to the more strict "probable cause".

    The current version of the law states:
    19 USC 1581:
    (a) Customs officers
    Any officer of the customs may at any time go on board of any vessel
    or vehicle at any place in the United States or within the customs
    waters or, as he may be authorized, within a customs-enforcement area

    person, trunk, package, or cargo on board, and to this end may hail and

    Certainly, nothing can actually stop jury nullification. Deliberations are secret, so unless some of the jurors speak out after the fact, nobody will ever know why a jury decided to rule the way it did.

    That said, jury nullification should only apply where the law itself is illegal (which means unconstitutional, in the case of the U.S.). If juries were simply to ignore any law or refuse to render any verdict they felt "wrong", then that leaves us with no law at all. Law does not exist simply as "suggestions" to juries.

    Where do we draw the line between the rule of law, and the right of the jury to disregard it? In the case of criminal trials, we should certainly lean towards giving Juries leeway in deciding a law unjust, but what about civil trials?

    In contract law, there is a principle called the "Parol Evidence Rule". Basically, if the clear written language of a contract contradicts oral discussions, or "intent", the written contract wins. Especially in situations involving intense two-way bargaining between the parties. (i.e. If a grocery store made you sign away the deed to your house in a 15-page 4-point-type contract when you bought a pack of gum, the judge would have some leeway. That is not the case here.)

    In this case, both parties were represented by counsel and there were extensive discussions between the negotiating parties.

    The CEO at the time, who was not directly involved in the contract negotiations, did testify he had a different opinion about what he thought his company was selling than what the negotiators testified. However, since the written contract is clear, there is no need for a jury to evaluate the credibility of the different witnesses, as the contract itself overrides any testimony a witness could give. If this were not the case, written contracts would be worthless.

    The parol evidence rule is a matter of law, as are the consequences of the contract language. If the contract was vague, THEN we could have a jury listen to testimony from the parties, but the contract language was clear: the copyrights were not transferred.

    Judges decide law, Juries decide fact. Deciding if legal language is vague or clear, and if it is clear, interpreting it, is a matter of law.

GSM/TDMA is spectrum inefficient due to the fact that silence takes up just as much bandwidth as voice. In addition, GSM/TDMA has a fixed maximum number of users for the cell. CDMA can theoretically handle a nearly infinite number of simultaneous connections on a cell, although as the number of calls goes up, the call quality goes down. For obscure reasons relating to carrier waves, CDMA has better penetration into buildings.
