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.

Canadian nuclear plants emit 40 times more tritium every day when functioning normally than the Vermont Yankee leak emitted in a year:

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:

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:

says, "more than 18 billion barrels of waste fluids from oil and gas production are generated annually in the United States".

* 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.

I said pretty much the same things, but much better:

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.

Ants *can* sort tiny screws in space!

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.

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

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.
