Natural gas gets to 60% efficiency with combined cycle generation. First the gas is burned in a turbine like a get engine and then the exhaust turns water to steam to run a second turbine. Peakers, which don't have the second cycle are much less efficient and are thus more expensive. Solar competes nicely with those. You can do combined cycle with coal as well if you gasify the coal first. It is unlikely that many of these will be built in the US but there is one under construction in Mississippi http://en.wikipedia.org/wiki/K...

+ - Navy Expels 34 Sailors in Nuclear Cheating Scandal->

mdsolar (1045926) writes "A Navy investigation of a seven-year long cheating ring in one of its most renowned training schools has resulted in the expulsion of 34 sailors from the Navy and another 10 sailors remain under investigation, the service announced today. The investigation, begun when a sailor tipped off authorities in February, found more than 76 senior enlisted staff instructors (E-6s and E-7s) at the Naval Nuclear Power School (NNPS) in Goose Creek, S.C. had participated in a system to cheat on the classified engineering watch supervisor (EWS) qualification.

The Petty Officers and Chiefs — assigned to the nearby Moored Training Ship 626 (the former USS Daniel Webster) Staff Training Group — created a network of thumb drives, CDs and emails known as the “Pencil File” aligned to the five versions of the EWS test, according to the Navy’s report of the investigation dated March 15 and released on Wednesday.

Due to their positions, the sailors knew which version of the test would be scheduled and pass out the so called, “Pencil Number” to the cheaters.

The Navy adjudicated 68 cases at Admiral’s Mast and found 36 sailors at the unit had been involved.

“Punishment was suspended for two of the 36 sailors based on their minimal involvement and their strong potential for rehabilitation,” according to the report. The remaining 34 had their security clearances stripped and were booted from the service.

A total of 78 personnel were found to have cheated on the EWS exam over the seven year period."

+ - Tuberculosis Is Newer Than What Was Thought->

Submitted by mdsolar
mdsolar (1045926) writes "After a remarkable analysis of bacterial DNA from 1,000-year-old mummies, scientists have proposed a new hypothesis for how tuberculosis arose and spread around the world.

The disease originated less than 6,000 years ago in Africa, they say, and took a surprising route to reach the New World: it was carried across the Atlantic by seals.

The new study, published Wednesday in the journal Nature, has already provoked strong reactions from other scientists.

“This is a landmark paper that challenges our previous ideas about the origins of tuberculosis,” said Terry Brown, a professor of biomolecular archaeology at the University of Manchester. “At the moment, I’m still in the astonished stage over this.”"
