Subsidy dollars per GWh are the relevant units. According to the EIA, and browsing through dsireusa.org, we find that "renewables" currently get the greatest subsidies by far.
* Radioactivity of fossil gas. This abstract http://rpd.oxfordjournals.org/content/97/3/259.abstract gives 200 Bq/m^3. It doesn't say where they measured, but given context of the paper I'll assume it was at the consumer end of the line, at STP. I don't know if gas used at electrical plants is any fresher, but I'll assume it's no more stale. Pure methane has an energy content of 55.5 kJ/g and a density of 667 g/m^3, or about 5 Wh(e)/L from a 50%-efficient combined-cycle plant. So about 40Bq/Wh, or 1 nanoCurie per Wh, or 9 Curies/GW-yr.
Any tie-in with copyright aside, Sousa was correct. Technology has negative sides, and music playback technology deeply damaged the participatory nature of music in our culture, and the associated music skills in the population.
A Hugo-award winning science fiction buff who doesn't realize that midi-chlorians are based on mitochondria? For shame.
While I would have preferred to leave the Force mysterious, I think midi-chlorians are one of the *best* revisions in the Star Wars universe. Understanding that mitochondria probably started out as bacteria which began living symbiotically with algae -- a symbiosis so successful, they do indeed provide the 'life force' to every eukaryotic organism on the planet.
One bug tracker, for bugs and new features, for all users internal and external. That includes developers.
If you have too many ideas, you'll need to filter them. The only thing that matters is how efficiently you can filter them by merit. I don't believe that preventing end users, and certainly not internal people!, from accessing the bug tracker is an efficient way to filter by merit.
How are they going to run the fusion part? The article doesn't say. In fact it's not clear what the innovation is here. The LIFE proposal from LLNL would use ICF fusions.
My advice is to not prematurely clamp the cord, as almost all OBs will do. Instead, have a homebirth, let the blood go into the baby for a few minutes after the birth, then tie the cord off. Works like a charm, and my 3-year-old has enjoyed an extremely healthy life so far. Another is due in April, and we'll be doing the same thing for him.
If a spammer really wants to, he can test his attacks against the site until he beats your filter. Filtering works impossibly well, but only if the output of the filter is private. Spammers may not be doing these attacks now, but if everyone started using Akismet, no doubt they would start.
One difference is that there's an established plan for recovering after the death of a U.S. President. Apple hasn't told investors what the hell they intend to do sans Jobs.
I have a Sensor at work and a Leap at home. I'd have bought a Sensor for home too, but they're hard to come by outside of corporate accounts. As it happens I probably like the Leap a little more overall. It's overengineered and overpriced but pretty much the best thing on the market. I find all the Herman Miller stuff to be cheap plasticy junk and the Humanscale Freedom chair is waay overengineered and basically does wrong things for the sitting.
I'm trying to think of when I've encountered security that wasn't theater.
* mechanical locks of all kinds * car alarms * antivirus software
All of these are not only ineffective (theater), they're usually at least as bad as the disease they attempt to prevent (lost keys, carrying keys, false alarms, automatic download and execution of useless resource-hogging insecure code...).
I'm replying to myself!
Some quotes from the Wired aricle...
green beams have a range of two miles, compared to a half mile for the red variety
Um, no. Range depends on power and beam divergence. Green is more visible at a given power because human eyes are more sensitive to green light than red. However I can easily blind you with an (invisible) IR laser.
"In January, a green laser was pointed at a Royal Flying Doctor Service ambulance plane in Australia, and the government responded by making pointing at aircraft with a laser punishable by stiff fines and jail time."
So it was *pointed at* a plane. Ooo, terrible.
"And in Albuquerque earlier this year, a police helicopter was nearly brought down after being targeted with two construction-grade lasers."
"Nearly brought down" with "construction grade" lasers. Hmm. How come it's only government craft that are having problems? Why haven't any news helicopters been "nearly brought down"? Could it be that the Police love trouble? Nah, that couldn't be it.

My hunch is that most (if not all) of the 'laser pointer distracts pilot' stories are urban legends. The fact that the cite here points to a Wired piece is the first clue. I own several very high-powered lasers of various colors, and I can't imagine how I'd be able to make them visible to pilots in airplanes, either small planes or commercial jets. Certain kinds of helicopters may be an exception. I remember some of these incidents coming out in local news channels... one in Arizona several years back I think. The articles have always struck me a suspect.
The solution to this (as well as to people balking at having to line up, mentioned in the main post) is to mirror the plane seating in the terminal. So you sit in your seat in the terminal. If you're not in your seat by the time they come to your row for boarding... standby for you. -Carl
Because it reduces your travel time. Plane still takes off at X, but you get there closer to X. For short flights, boarding time can be significant. -Carl

Canadian nuclear plants emit 40 times more tritium every day when functioning normally than the Vermont Yankee leak emitted in a year:
http://atomicinsights.blogspot.com/2010/03/how-much-tritium-leaked-from-vermont.html
A 1 GW(e) natural gas turbine will emit about 9 curies/year,* which is 20 times the rate of radiation from the VT Yankee leak at its highest.
Oh, and natural gas "fracking" produces toxic and radioactive wastewater. This article from last summer discusses EPA tests that found nasties from the fracturing fluid in domestic well water:
http://www.scientificamerican.com/article.cfm?id=chemicals-found-in-drinking-water-from-natural-gas-drilling
New York State is doing fracking in something called Marcellus shale. This article from last fall says that surface wastewater from these sites was found to contain Ra-226 in concentrations "thousands of times" the limit for drinking water:
http://www.scientificamerican.com/article.cfm?id=marcellus-shale-natural-gas-drilling-radioactive-wastewater
This page
http://www.epa.gov/radiation/tenorm/oilandgas.html
says, "more than 18 billion barrels of waste fluids from oil and gas production are generated annually in the United States".

The Prius doesn't make economic sense in terms of gas savings either.
