  1. Rotation - is it absolute?

    If it’s rotating, it’s not inertial. If it’s inertial, it’s not rotating.
  2. Removal of the down-vote, yes or no?

    This assumes you can get in and change the code.
  3. Gun control, which side wins?

    So IOW your expertise is as a participant, in one narrow area of law.
  4. Salt water eletrolysis idea

    Cavitation from the propellers — the low pressure allowing bubbles to form and then almost immediately collapse — makes noise (and causes damage to the propeller), and is something Endy mentioned as a possibility. But propeller cavitation is a low pressure event, collapsing because the bubble moves to a region of higher pressure. A high-pressure bubble would not have the same instability.
  5. Gun control, which side wins?

    I was not summarizing your comment, I was summarizing Raider5678's. "States do have the right to put pretty much whatever restrictions they like on guns unless deemed unlawful by the Supreme Court." and "So if the politics on a national level are too corrupt, states do have the ability to place their own laws." I think you may be reading way too much into the statements. So you're a lawyer?

    Yes we have bribery laws. Donating money to campaigns does not violate those laws. There has to be a clear quid pro quo to be bribery. Can you discern the irony there, of being shocked that gambling is going on, while being handed gambling winnings? My understanding is that there are patterns to be recognized within this. It's not just having bruises, it's particular bruises, and happening repeatedly. Which still leaves the false positives question wide open. If you identify 10,000 at-risk students and one of them end up an actual shooter, how effective will the program be?
  7. Salt water eletrolysis idea

    You're probably not releasing a huge volume all at once. "Sixteen electrolytic cells at about 1000 amps are required to produce 120 SCFH of O2 (sufficient for 120 men) " http://web.mit.edu/12.000/www/mission2005websitefolder/a2/8/pdf1.pdf 2 SCF per minute. So twice as much hydrogen, but it's also venting under pressure, probably continuously. If you're 100 ft down, that's 3 atmospheres of compression. 3 cubic feet becomes 1. And that will tend to disperse as it rises.

    Your first proposal (i.e. what I responded to) did not include other risk factors. How do you do this without violating medical confidentiality and free speech? How do you track tactical accessories, or "feelings of disenfranchisement"? Do you cross a kid off the list because he doesn't have known access to guns? Despite the fact that he could get them later? My high school had about 1600 kids when I was of that age. So you might have had 500 or more who had some kind of access to guns (including me). In a group of 500 teenagers, how many are going to have these feeling and/or leanings? It's certainly not going to be just one or two. Now you have this burden of checking these students out, possibly stigmatizing them (and many will already have a dislike of authority; will this help?) . This sounds like a page out of the "the beatings will continue until morale improves" manual. A system that generates too many false positives will eventually be ignored, and a system geared specifically for schools addresses a narrow slice of gun-related issues.

    There are a number of elected government officials who have received substantial contributions from the NRA, of whom Trump is one. (Being shocked was sarcasm. See Casablanca for the reference)
  10. Arming Teachers

    I'm shocked, shocked to find that the gun manufacturing lobby organization is advocating more guns as the solution. At one mass shooting per day, that's ~3650/10 years in the 40% of the ~125 million households in the US. 0.007% is not much of an indicator. Why does that matter? It could be a bad person who has decided to do this, and grabbing the gun becomes (part of) their plan. They would have the element of surprise on the first victim. It's not like the teachers who carried would remain secret very long. They might even write "now I have a machine gun ho ho ho" on the teacher's shirt after killing them.
  11. Salt water eletrolysis idea

    Since they both require oxygen, it would probably be a matter of how much space it takes up. And I suspect diesel wins, because the energy density of the fuel is going to be much greater.
  12. Gun control, which side wins?

    I don't think that's a fair assessment. The states can pass gun restrictions. The Supreme Court can rule them to be unconstitutional. I don't think there's anything controversial in that position.
  13. Salt water eletrolysis idea

    Plus, if you have a reactor, there is no need for this stored energy.
  14. Rotation - is it absolute?

    If it's rotating it isn't an inertial frame
  15. Gun control, which side wins?

    Federal law is enforced by federal officials, e.g. the FBI or ATF For example, the feds could (and recently threatened to) enforce marijuana laws despite legalization at the state level. If federal gun legislation is passed, the states will not be able to "thwart" it. The US has the opportunity to legally overthrow the bulk of the government every 2 years. All of the house and 1/3 of the senate.
