You made some mistakes(mixing up units).. the lowest possible temp is -273.15C or -459F, or 0 kelvin. (absolute zero). Increase in flame temp when combusted with air will be approx +10.4C.. (0.04 * 2483K) + (0.96 * 2223K) - 2223K = +10.4K.

+10.4K/(2223K-290K(or 323C)) = 0.53%(17C) to 0.55%(50C) increase in efficiency to help offset 4% H2's 2.71% reduction in energy content. Since most applications are direct thermal usage(water/hot air/etc) no additional losses will be incurred.

As for losing ~2.2% of heat energy, in exchange for cleaner burning fuel. It's a tossup.

Err. The 4% H2 portion burns hotter than other 96% ch4 & c2h6, so the hotter flame temperature is going to help make up for some of the 2.8% loss in energy density for any given volume of gas.

Beyond 4%, I expect we'll build a separate underground H2 storage network, were surplus Electricity delivered to site nearby a Combined cycle CH4/H2 power plant.. Electricity converted to H2,stored underground, and piped in separately to CCPP as needed/available.

As renewable energy percentage increases, within a few decades those CCPP's will be powered by solely stored H2, and CH4 will be conserved for other usage. Eventually, to help nature along, we'll extract carbon from either the ocean and/or atmosphere, and then combine it with H2 to make CH4 and pump it back into the ground.

This is not about a defective boiler pump.. It's about a reoccurring problem with broken boiler re-enforcing wires

They found a broken boiler spine in 2007, and spent 150 million pounds investigating fixes.. from what I've read they found more corroded/broken per-stressed re-enforcing spines.

excerpt from report dated Sept 2010,

"3.4. Leaking pressure vessel cooling water was also found to have entered a chamber containing BCU pre-stressing wires and as a consequence of this, a programme of radiography to reveal corrosion degradation was initiated. During inspections on Reactor 1 at Hartlepool in late 2007, the tendon wires were found to have unexpectedly high levels of corrosion, which led to one tendon wire having broken near to its anchor. Subsequent inspection of the BCUs on these other reactors found similar evidence of corrosion, indicating that this was a generic issue, not confined to Reactor 1 at Hartlepool."

That's just the tip of iceberg.. M$ cutoff access to my Win 7 version of skype 6.6,0.106.. last updated 6/13/2013 !

I don't appreciate relativity simple applications requiring a constant stream of updates. It makes me think it's some sort of NSA/Gov spyware. It's better to just remove it and forget about them, too much hassle for little return value. Write them off and move on..

P.S. Oracle Java is quickly approaching negative return threshold and may soon join skype in my list of unstable/unreliable applications/addons.

Samsung's position is entirely rational, but less than ethical.

more than ethical, for different reasons.

Since Microsoft purchase Nokia, they must enter into a cross license agreement or pay royalties to Samsung. Now M$ may pull an Apple and claim they shouldn't have to pay for standard essential cell phone patents.. But that argument becomes a double edged sword, since M$ patent licenses cover the standardized memory card file format(oopsey - standard essential ) . So what's good for the goose is good for gander so to speak..

Samsung clearly and right fully, thinks they shouldn't have to pay M$ any more royalties, since the material terms of the contract have changed since M$ has become a cell phone manufacturer.

Contamination is quite reversible

.. Oh, you didn't mention that it takes six hundred years for the deadliest of the food chain isotopes (Cs-137, Sr-90) to decay to a reasonable concentration.. Yep other than that, contamination can be reversed.. Just not in a typical human life span .

P.S. Even time passage of a million years has little effect on some the other longer lived fission isotopes. Like Cs-135(6.9% fission yield, I-129, 0.84% yield).. Iodine-129 is particularly nasty since half of an animal's Iodine is concentrated in the thyroid gland. A 60,000 gram human has a thyroid that weights ~15 grams, you do the math.

I'll add a couple of corrections to your list
4.3) CO2 absorbs IR photons, but also re-emits IR photons, but in a randomized spherical manor.
4.5) Increased randomization of IR photons interferes with the normal flow of energy from earth's surface to outer space.
4.7) As CO2 concentration increases more and more IR photons are re-directed back towards earth's surface at all levels of the atmosphere.
7) The net effect of increasing CO2 concentration increases temperature near earth's surface and decreases it at high altitudes.

"Current CO2 concentration is 380 ppm or so."

You're a bit out of date(2010), I see. Atmospheric CO2 has been crossing the 400ppm mark lately, (avr 399 ppm)

Over the last year(june2013-june2014) it climbed by 2.56ppm, and that rate of increase appears to be accelerating, thus humanity is going to be in deep doo-doo real soon if we don't stop burning fossil fuels.

The other facts you seam to be missing, Our star(SOL) was somewhat dimmer in the past, thus requiring much higher CO2 levels to keep the earth from freezing over. And that humanity is totally dependent on the current climate patterns..

Technically, Qualcomm violated the GPL license on the code it contributed to github.. Speciffically, the clause which licenses the code in perpetuity. Thus they can no longer offer their products for use in any Andriod phone or device which uses GPL'd software.

But if looks like Qualcomm has quickly seen the error of its ways and issued a retraction/apology.

"40 years, another 1/2 trillion tonns of CO2".. is a significant under estimate!

Humanity is currently dumping 36 billion tonns(2013) of CO2 into the atmosphere each year. Projecting out using 2.1% yearly growth rate, humanity will hit that 1/2 trillion tonn mark in 2025. Just 11 years from now.
