    Is there a way of producing foamed concrete?

    Yes, it's called http://www.cement.org/basics/concretebasics_airent rained.asp >air-entrained concrete.

    It's been used for decades for building floating docks, among other things. If you have enough air in the mix, you can make it less dense than water.

    one of their biggest selling points

    Windows is not a selling point for the Mac at all. Apple only released BootCamp because too many people were bricking their machines by trying to modify their EFI without knowing what they were doing. Apple doesn't sell windows, they don't support windows, and if what you want to do is run windows, then you're on your own and that's entirely how it should be. If you need to run windows apps, buy a thinkpad.

    Shame SHOULD be a check on social behavior.

    Exactly!

    People tend to forget that there are all kinds of ways to bring pressure to bear when someone is behaving badly or stupidly, and that leads to stupid shit like state legislators trying to outlaw teenager's fashion choices. The law is a very blunt instrument.

    Incidentally, I would very much like to see shame used to regulate even more egregious examples of legislators wasting our money.

    The biggest danger of all in this is false accusation.

    There's a reason why we don't allow anonymous accusers in criminal proceedings.

    Jehovah's Witnesses are covered under the First Amendment.

    Well, yes and no. Saying what they want to say is their right, but coming onto my property is not. So, if I post a "no soliciting" sign, and a prosyltute comes up to my door to try to recruit me, they are told in no uncertain terms to leave and never come back. To date, I haven't even had to raise my voice to get rid of them. If one of them were to persist, then a call to the police and a restraining order would likely follow.

    Consider the flip side of this, though. Back when communism was collapsing in east germany, I remember seeing the crowds marching in Leipzig, and they were chanting Wir bleiben hier! ("we're staying here"). Before that time, most East Germans just wanted to escape to the west. After that point, they realized that they were being ruled by the will of a minority, and that was game over for the commies in Germany. What the thugs were most afraid of in East Germany, and what the Red Dynasty, the Saudi kleptocracy, the Burmese military oligarchy, the Castro dictaorship, and every other criminal regime around the world is most afraid of, is quick and effective internal communication.

    So, in the scenario you describe above, your hypothetical suffragettes are rather like the samizdat authors who hid in the shadows during the communist nightmare. If they get exposed, then it sucks to be them, but isn't there also the effect of other people wondering why it's so important to them that they take that risk? Eventually, despite arrests, harassment, and physical attacks, the suffragettes convinced the USA to let women vote.

    And how well are they performing that function?

    Some better than others. If you want the specifics, try Google Finance. All the publicly-traded automobile makers make quarterly reports of earnings.

    I really think that any car maker (even a new one) should be able to produce a turbine/electric hybrid that lasts forever, is a simple design, and can be mass produced like the Civic.

    Well, if you're sure, then raise about $1M from your friends and family, build a prototype, and then see if you can come up with major venture funding to get it off the ground. Good luck to you!
