Comment Re:Gas not less CO2 on refiring coal plants (Score 1) 143

If you just replace coal with natural gas in the same plant to heat the water it is not significantly less CO2

Burning coal is pretty much just turning bulk carbon into carbon dioxide. Burning natural gas (methane, CH4) creates carbon dioxide, too, of course, but also releases energy from burning the hydrogen to make water. As a result, the combustion of natural gas produces less CO2 for the same energy output. From the Energy Information Agency - Pounds of CO2 emitted per million BTU of energy: Coal (anthracite): 228.6 Gasoline: 157.2 Natural Gas: 117.0 [I'll apologize for the units - I'm just quoting the result. If you must know, 1 lb / 1e6 BTU is equivalent to 0.43e-3 kg/MJ. Or, just look at the number as a figure of merit: lower is better.] more data here

It is even more effective than that- these numbers don't take plant efficiency into consideration. The "per million BTU of energy" is just the amount of heat produced, not the amount of electricity. A very efficient traditional coal plant is about 35-40% efficient in turning the heat into electrical power. A typical combined cycle gas power plant is about 57-60% efficient due to the nature of the different cycle. So, on a per-MW produced basis, Natural gas looks a lot better.

It also doesn't hurt that natural gas is at all-time low prices in the US thanks to our gas boom and the high cost of transporting natural gas across oceans. Gas is cheaper than coal now in many places. The only coal plants which are going to survive are the more efficient plants with short coal supply lines. It has little to do with environmental concerns, it is strictly an economic calculation in many cases. The environmentalists didn't defeat coal, the accountants did.

That was then. Today we have settled on standardized new-generation plant designs that avoid this problem.

What's really needed is a change in our legal system to eliminate the disproportionate power that small groups of activists have to disrupt construction. Their strategy is to raise costs by imposing phony legal delays on construction after the initial approval.

As a guy who very recently was involved in selling new power station equipment, I can say with 100% confidence that there is no such thing as a standardized power plant design in the USA. I was selling turbines to Duke, Southern Company, Exelon, Luminant, and many others. Every customer wanted something different. Some of them wanted triple redundant instruments on valves, and some were happy with dual redundancy. Some of them wanted the generator protection system to be redundant on 2 different vendor's kit, and some wanted redundancy with identical cabinets from the same vendor. Some wanted a stainless steel oil tank, and some were fine with the carbon steel + epoxy coating tank. Some of them wanted to have a large turbine deck to make maintenance easier, and some were cutting that cost since they were going to flip the plant anyway. We went into great detail about even the most mundane of things. Some of the customers wanted to have all our equipment numbering changed to their (internal and proprietary) numbering standard so that all the plants they owned had the same numbering scheme. No matter what our "standard" design was, someone had a problem with it. These guys know what they want and if it isn't included in your "standard" design, they want a price to make it happen.

This is a different philosophy from Europe and Asia, where standard designs are common and even preferred. But that's the US power market. Toshiba/Westinghouses' standard AP1000 plant isn't good enough for any of the US utilities who can afford to build such a thing. All the customers have their little quirks of wanting to be a little more safe in one area, or a little more convenient to operate, or a little cheaper to build. None of those changes affect the core safety principles of the design, they are just different. They do, however, drive up the build cost. Additionally, these plants don't get build often enough to keep the same crew on each job. By the time you build Unit #2, 10 years has gone by and a lot of the people who built Unit #1 have changed jobs or retired. It is difficult to keep such specialized experience in the economy if it is needed so rarely.

I am sick of these "challenges" that effectively try get programmers to work for effectively well below market rates. As if we're like children, a "challenge" is supposed to make us set aside months or years of income to work on a really difficult problem that if we had to actually go out and do for a company in the job market, we'd be paid $100K/year or more..

You're completely missing the point. They've found the Stargate and egyptologists are a dime a dozen. They need to form an elite team of programming and AI experts who will decode the symbols on the Stargate and defeat Apophis. This is just a fancy recruitment test.

In what way is he using the words "tyranny" or "cheat" in a non-hating way?

Well, there's always the title, itself: "The Tyranny of Cliches". Juxtaposing a violent word like 'tyranny' with 'cliche', should, in a thoughtful reader, invite some question as to what he's on about. "How Liberals Cheat in the War of Ideas" informs us that the cliches are rhetorical roadblocks to discourse:

Goldberg's revelations are meant not to compile an interesting batch of factoids to drop at dinner parties, but to illustrate his thesis: the left employs clichés in order to cloak its ruthless, ruinous ideological aims in the language of easy-listening rhetoric, all the while denying that it is promoting a program attempting to establish a technocratic all-encompassing state in the name of the pragmatism of Progressivism: "The greater good"; "Social justice"; "Violence never solves anything"; "Power corrupts."

Your attempt to label Goldberg "hate speech", itself, is an example of the sort of cliche Goldberg exposes.
Your purpose appears to be to silence, not engage in legitimate debate.

I had a system where switching a SCSI card with a NIC from PCI1 to PCI2 (and vice versa of course), made Windows 2000 bluescreen. Just switching those two cards. Nothing else and the SCSI had only a scanner attached, no bootable devices.

So, yes, that is long ago, but Windows 2000 implies at least the year 2000.

Linux didn't complain at all.... Yes, I was running Linux back then in dual boot.

Submission + - Republicans Block Latest Attempt at Curbing NSA Power 2

Robotron23 writes: The latest attempt at NSA reform has been prevented from passage in the Senate by a margin of 58 to 42. Introduced as a means to stop the NSA collecting bulk phone and e-mail records on a daily basis, the USA Freedom Act has been considered a practical route to curtailment of perceived overreach by security services,18 months since Edward Snowden went public. Opponents to the bill said it as needless, as Wall Street Journal raised the possibility of terrorists such as ISIS running amok on U.S. soil. Supporting the bill meanwhile were the technology giants Google and Microsoft. Prior to this vote, the bill had already been stripped of privacy protections in aid of gaining White House support. A provision to extend the controversial USA Patriot Act to 2017 was also appended by the House of Representatives.
