The outside layer of molecules in the crystal lattice have a bit more freedom to wiggle, so they'll heat up quicker in the microwave. Also, the outside layer is in contact with the air, so that also helps to thaw it.
The potential for improvement in battery or supercapacitor is much greater than the potential for improving hydrogen storage techniques, and good quality batteries/capacitors will be more beneficial in many areas of our lives.
If you start with crude oil, and you take the diesel out, you are also left with a bunch of gasoline. That means that the ratio between diesel and gasoline powered cars will be relatively constant.
I have a bunch of CDs, but I never play them. Whenever I want to hear a song, I just download a copy. This should be okay, since I've already paid for the CD.
Depends on where/how you live. Quite a few people live in an apartment building or other types of houses where they can't reasonably run a power cord between their home and their car.
The heat flux from the earth's core into the oceans is 100mW/m^2. Heat flux from the sun is 1kW/m^2. As far as global climate is concerned, we can safely ignore geothermal effects.
The automatic system will flag the mistake first, but if you commit a serious crime with that, the next step will be for a human investigator to compare the faces, and realize the automatic system had a false positive.
Even without the CO2 problem, we need to get going with alternatives for fossil fuels, as they will be getting too hard to produce in sufficient quantities in a few decades.
No, you do your homework. Natural sources are huge, but so are natural sinks. Without the human contribution, they would balance each other out. Human CO2 production is tipping the scale, year after year after year.
What is the chance the current temperature rise is just natural variation (i.e. noise) ? And what would be the limit to conclude that this hypothesis is false ?

And don't make them all speak English...

Can't you just reconfigure the main antenna to emit a reverse tachyon beam ?
The only innovation they are doing is coming up with better ways to count their money.

And luckily, everybody in the world lives in the US.
What change of course do you suggest to fix the problem ?

So you personally design all bridges that you cross ?

I already know the answer. I like to hear what parent thinks.
In the history of the planet, when CO2 was 20 times higher, the output from the sun was also (significantly) less.

Terrorists use plate tectonics now ?
About the same as with a shorter underwater tunnel, such as this one http://en.wikipedia.org/wiki/C...
I use my solder paste straight out of the refrigerator. I actually prefer the firmer consistency that way. It easily lasts 6 months in there.
Add shipping cost, power supply, breadboard, interface cables, and the difference in price is negligible.
