Cryogenic air separation is the primary process by which air is distilled into its components. The only inputs are air and electricity to drive the main air compressor. I imagine the electricity used to drive the air-sep process is less than the plant produces by a considerable margin.
The plant could have a dedicated air-sep unit or have oxygen delivered by truck in liquid form.
Separating kids into career trajectories early on is a fantastic practice from a statistical standpoint, but I don't want to be the one to tell mom and dad that Johnny might make a better auto mechanic than Brain Surgeon.
That's why the American educational system tells every student that they're special. It's easier.
On an industrial scale, cryogenic lines tend to be vacuum jacketed - meaning there is an inner pipe for the cryogenic fluid and an outer pipe to create an annular space from which the air is removed. That takes care of conduction and convection. Use the right paint/insulation inside the line and you minimize radiation as well.
So you still have an issue if you develop a leak since you've lost vacuum along a section of the line.
I'm suspicious of anybody who's primary career goal is politics - ie Polysci Degree -> Staff Position -> Local Politics -> National Politics.
I'm much more inclined to vote for someone who enters politics from a different path. They're the ones who haven't been selling little pieces of themselves along the way.
I wouldn't go that far. It's Youtube's discretion as to whether or not they remove a video. Something like this looks legit at first glance, but a mass email would be written off.
In theory, the major Oil Companies have been energy companies since Theodore Levitt's "Marketing Myopia" gained traction in the 60's.
The reason the major railroads aren't so major anymore is because they saw themselves as rail companies, not transportation companies. That mindset allowed air travel to take most of their passenger business.
It is in the interest of oil companies to explore new energy technologies. That said, it is naive to think they wouldn't try to get as much out of their current investments as possible. The companies that do that will be the long-term winners.
This is not an apt comparison. You need to look at the obese/fit argument certeris paribus - all other things equal. Kudos to you for having a small environmental footprint, but the woman you describe is a poor justification for not improving your health.
Underlying this discussion is the resentment that fit people have for the obese. As an intelligent, fit, hard-working American, it annoys me that people in other parts of the world consider us to be stupid, fat, and lazy. When I see people who are (in no short supply), I resent them for making my country look bad. Aside from the impression the rest of the world gets, people who are unhealthy cost more (Read: more of my money) to take care of. I feel the same way when I see people smoking.
There are people with legitimate medical reasons for being overweight, but you don't reach such a high proportion of the population without societal reasons.
I was at an event called the Green Grand Prix a few weeks ago. Chevy and Honda had H2 fuel cell vehicles there which ran compressed hydrogen as opposed to liquefied. The company representatives were unable to tell me what the difference in the energy density was, but it's something to consider.
You are correct to say that liquefying H2 is an energy intensive process and that liquid H2 poses significant storage and transportation challenges.
There's a reason that hydrogen today is produced by cracking oil and not extracted from water. Most hydrogen is made from steam methane reforming (SMR). Hydrogen is used in hydrocracking - a process which removes contaminants and upgrades the octane level of the product.

Because women can tell the difference between $100 shoes and $40 shoes.
That's what it all comes down to in the end, for both sexes.

I'm not saying it was a good justification.

Obama justified his vote by saying that the rest of the bill was important enough to stomach the teleco immunity portion.
