I'm attending ISDRS in Bethesda this week and presenting a paper tomorrow. It was interesting but I'm not entirely sure how well it would work. I'd have to see the actual data (which usually isn't shown in such presentations) and try it. It had to do with passivating the oxide-silicon interface with deuterium instead to reduce the number of hot carriers injected through the oxide. My review: interesting but I want to repeat it and see it in action.
From a Wall Street Journal article about a year ago, China is responsible for nearly half of the world's global atmospheric mercury output. The reason for this is their extensive use of coal as an energy source without any chemical scrubbers (yes, these exist for mercury too). I don't recall the exact amount of total output for the world, but it's many, many tons. If you really want to focus on an environmental issue, focus on mercury. The harm that it causes is not disputed and that is the reason that pregnant mothers are advised AGAINST eating fish on a regular basis.
I'm actually making devices to do this as part of an undergraduate research project. The devices I'm making are passive with frequency response up to the 100 GHz range. The best part these is that they don't require any DC bias and as such aren't subject to 1/f noise like schottky diodes. Right now we're looking at applications for security (really advanced metal/explosives detector) and aviation (water vapor is transparent in that frequency range).
oceans are enormous, % ionization of H2CO3 is very small (aka: weak acid), oceans are a big buffer solution... the effect would be negligible! a little knowledge goes a long way... --qk
The Bernoulli effect in itself is not strong enough to provide the lift for the aircraft. It merely is responsible for holding the airflow to the upper surface of the wing with a given angle of attack. I fly indoor model airplanes (rubber band powered free-flight) as a hobby, and i can tell you that we certainly do not have flat-bottomed airfoils. Our wings are simply ribs and spars covered on the top (covering the bottom also adds too much weight and decreases the effectiveness of the angle of attack). Without the bernoulli effect, we would not be able to have such an angle of attack in our wings without causing turbulence on the top of the wing when the airflow doesnt hold to the surface. this phenomenon disrupts the airflow over the top of the wing... most of us call it a "stall".
I am not sure exactly what he means in relating superstring theory to rubber bands, but "Dicky" is Richard P. Feynman (brilliant physicist, won nobel prize in physics for an idea that came from watching a spinning dinner plate) and "Neuton" was probably a misspelling of "Newton" (Isaac Newton, need i say more)... Hope I was of some assistance...
I doubt there would be too much environmental impact, seeing as the atmosphere (as in the air we breathe) is about 78% nitrogen, 21% oxygen, and 1% trace gasses (varies slightly for urban areas.....) as long as the nitrogen is not in an extremely concentrated cloud, people should still be able to breathe. i remember reading somewhere that if the air one breathes exceeds 12% CO2, one will asphyxiate (sp?). IMHO think I would rather breathe the nitrogen... but thats just me.
I propose that you all read a book entitled Black Holes and Time Warps -- Einstein's Outrageous Legacy by Kip Thorne... Maybe you all could benefit from a little knowledge about this subject...
umm, yeah.... sorry, but why do you think the speed of light is called "c"? it is a constant (2.99792458*10^8 m/s). also, light the electrons in the form of electromagnetic waves travel at c (10 m/s is nowhere close). You are correct about the frequencies, but all electromagnetic waves travel at the same speed, regardless of speed. the medium only shifts the wave-form. Isn't it so much fun to probe the intricacies of quantum physics? Please learn some more physics, correcting posts like these really bores me...

edit: deuterium instead of hydrogen... I'm obviously tired.

I would love to have a beowulf cluster with these things...
:(
...if only I had the money!!!
Of course, it might be for the world's better good that I don't.
