The velocity with respect to what?

Basically, if Newton's laws work, you are not being accelerated.

Depends on the gas. Some atoms or molecules are gases at room temperature and pressure. Some need to be heated. Depends on the boiling point. (Technically, everything has a vapor pressure, so you will find some gas of even a metal at room temperature - but it's a very, very small amount compared to the other constituents.)

There are two types of people: those who categorize people into two types, and those who don't.

I decide? Good. As a refutation of relativity, it's crap. Game over. Thanks for playing. The page loads now that I am on my home computer. Your clocks are 15 light-seconds apart. All you are doing is measuring that they are 15 light-seconds apart. An observer at any position will be x light-seconds away from one clock and 15-x light seconds away from the other. One reading will always be T-x, and the other will be T+x-15 (ignoring your offset). When you add them, x cancels out, so all observers see 2T-15. Wow. You've discovered algebra. <yawn>. Note that you have assumed Galilean transformations. Relativity hasn't come anywhere close to your dicussions, so I don't see how you can conclude that it's wrong.

A bar walks into a man... ooops! Wrong reference frame. How about science cartoons? Non-science ones

Yes, there's a pipeline from Prudhoe Bay to Valdez, in Alaska. But I'm pretty sure that any pipeline running through Canada is natural gas.

Copyright ownership does not imply orginality. You can sell or transfer copyright ownership. Copyright of cartoons in the New Yorker magazine, for example, are owned by the magazine, but were created by the individual cartoonists.

This year's group is Brood X, but as the numbering implies, there are many different broods. There are also 13-year cicadas. But brood X is the big one, and in full force in the mid-Atlantic. The chorus sounds like the phasers from the original Star Trek, and the mating call buzzing and clicking has started. More info here

I think that's a gas pipeline(s) that goes through Canada.

What circumstance do you envision would lead to that? It would mean either you paid someone for the copyright or the work was created as part of the normal course of their job, with you as the employer (i.e. a work for hire). I don't see how either gets you around a rule saying you have to do original work.

We're already using that electricity. You have to build new plants for the hydrogen electrolysis. So, in the US at least, that kinda rules out nuclear for the time being.

How is that, if you have to burn fossil fuels in order to get the hydrogen? Your pollution level is the same (or worse, because the efficiency of the processes isn't 100%)

That's only true as long as you don't ask where the hydrogen came from. Since the answer to that is "fossil fuels," hydrogen doesn't actually solve any problems of fossil fuel consumption.

I've seen that attributed to Dan Quayle, from Esquire magazine. Given the multitude of copies that have propagated across the net, I wouldn't take anything as authoratative. I've even seen attributions that have Al Gore saying this.

The invention will never be practical. As I implied and Aman stated, you have to do work at some point in getting the log into the high-pressure end (i.e. bottom) of the device. Ignoring losses, that will be exactly the amount of energy you would recover from dropping it after it reached the top. With losses, it becomes a net work/energy sink. You heat the water up a little, and it makes noises. Whoopee.
