Comment feed myself w/ knowledge & history of steelmak (Score 1) 737

...When Bessemer went to push them into the ladle, he found that they were steel shells: the hot air alone had converted the outsides of the iron pieces to steel. This crucial discovery led him to completely redesign his furnace so that it would force high-pressure air through the molten iron using special air pumps. Intuitively this would seem to be folly because it would cool the iron. Instead, the oxygen in the forced air ignited silicon and carbon impurities in the iron, starting a positive feedback loop. As the iron became hotter, more impurities burned off, making the iron even hotter and burning off more impurities, producing a batch of hotter, purer, molten iron, which converts to steel more easily....He realised that the technical problem was due to impurities in the iron and concluded that the solution lay in knowing when to turn off the flow of air in his process so that the impurities were burned off but just the right amount of carbon remained. However, despite spending tens of thousands of pounds on experiments, he could not find the answer.[7] Certain grades of steel are sensitive to the 78% nitrogen which was part of the air blast passing through the steel.

I don't know precise formulas for 19th century steelmaking, but I know right where to look in a library. There's was a PhD in the family for metallurgical engineering. Now materials science. I'd feed myself, won't freeze to death.

Comment I attended Historically Black College. Ooops. (Score 1) 448

White guy who attended a Historically Black College on a Minority Scholarship. To make real long story brief, Federal lawsuits against Old Dominion Univ. and Norfork State Univ. for state schools so close geographical, opposites racially. There were some extra scholarship money to help balance the schools in 80-90's. My first year of college was Norfork State. Lived in the dorms. I made a ton of great friends. People at NSU bent over backward to try to make me feel at home. Terrific experience.

Comment It's Black folk who HATE Condi Rice. (Score 2, Informative) 448

Condi Rice is as black as Barack Obama's corporate lawyer wife. Condi Rice is utterly detested by her fellow black folks for going on a NYC Ferragamo shoe shopping spree and catching a Broadway Musical Comedy, Spamalot, quite literally as Hurricane Katrina came ashore in New Orleans and her brothers and sisters were fighting for their lives. Quite literally fiddling while Rome burned. You forgot, huh? Here's snopes.com to reminds you...

"...That evening, upon arriving at the Palace Hotel, I flipped on the television. Indeed, the hurricane had hit New Orleans. I called Henrietta, who said that the main issue was making sure our people were safe. She'd also convened a departmental task force because offers of foreign assistance were pouring in. I called Secretary of Homeland Security Mike Chertoff, inquiring if there was anything I could do. "It’s pretty bad," he said. We discussed the question of foreign help briefly, but Mike was clearly in a hurry. He said he'd call if he needed me. I hung up, got dressed, and went to see Spamalot.

The next morning, I went shopping at the Ferragamo shoe store down the block from my hotel, returned to the Palace, and again turned on the television. The airwaves were filled with devastating pictures from New Orleans. And the faces of most of the people in distress were black. I knew right away that I should never have left Washington."

The metaphorical White Man has a heavy burden here. Reach out to the savages, and there are adverse consequences, suffering, death, and loss of traditions going back millennia. Stay away, and people who should be your fellow human beings are cut off from the fruits of civilization, and are treated like livestock whose habitat must be delineated and (un)managed to keep their numbers healthy so that more children can be born into a life where their greatest aspiration can be to live just like their grandfathers going back tens of thousands of years.

You'd need battery warmers to weather the overnight cold, but assuming they'd be plugged in to charge during the worst overnight cold, the battery heater would be running during the lowest temperatures with the standard use procedure.

The real question is what happens if you get a cold snap in the middle of the day. Since most suburban school districts stagger the school day for elementary, middle, and junior/senior high schools to minimize the size of their bus fleets, it's quite conceivable that these things would be on the road for close to 8 hours straight without a chance to recharge in between the morning and afternoon commutes.
