"negative reflraction index lenses"
Materials with negative refraction indices have already been created two or three years ago. They are made out of different components which together do the trick. Don't ask what it was, search Science or Nature and you'll find probably more than one article.
Yey material and nano science;)
What you are referring to, I guess, is that IBM spelled "IBM" with single atoms in 1989 using a tunneling microscope.
Doing this with molecules would increase the size of what you write, not make it smaller.
Why? Molecules are made up from two to very many (100000 easily) atoms.
Even though I know you're just joking, here an answer:
No, because the high energy of x-rays will damage your body severly. Oh, and of course because x-rays aren't so common unless you actually have a source (or float around in space). So not much to see and if you do those newly gained receptors would be broken pretty soon again. I think.;)
I'm paying 16 for theoretically 20MBit DSL (flatrate) in France (effecively where I live it's 7MBit DSL). Plus another 20 or so for phone service (ISDN).
In Germany I pay 45 in total for 2MBit DSL (flatrate) and regular ISDN phone service.
Yes, France is cheaper and faster, because their government cares about internet access more than the German one...
No central or western european country has any state-run telephone/internet companies anymore. All nations have broadband faster at equal speed or even much faster than the general internet connection in the USA.
For example:
France has DSL 20MBit in cities and DSL 6MBit in other areas, Germany has DSL 6MBit in cities and at least 2MBit in rural areas with 20MBit coming this or next year.
You hope/uninformed prophecy will not come true, because internet connectivity in Europe is already past the state you describe for the future.
I just wanted to say that Hydrogen is not so safe as the parent to my original reply made it sound. Even if only a small area that is affected by sudden combustion, a person inside it will be in a very bad shape afterwards.
Personally I'd prefer Hydrogen cars any second over gasoline cars.
Your information is not correct. As already stated by another reply (which didn't get modded above 3) Hydrogen (H2) will form a very explosive mixture with air, also called detonating gas (if the translation from German is correct where it is "Knallgas"). This mixing happens always when you have Hydrogen meet regular air.
So saying Hydrogen would be safe and just rise into the atmosphere is nothing but completely wrong and unsafe. In case of an accident there will be heat sources (be it a fire or a hot engine or the rapid compression of a gas tank) which will easily ignite the hydrogen:air mixture and cause a nasty, big explosion.
Keeping Hydrogen gas inside metal gas containers is no problem, by the way. You can buy and store it, just like other gases (for regular materials the size difference of He- and H2-molecules really don't matter).
On another note, it doesn't really matter if a catalyst is toxic, since by definition a catalyst is only needed in small amounts and will leave every chemical reaction unchanged. Thus it can be reused unlimited as long as it does not physically get thrown out of the fuell cell.

The problem with this logic is that GE food is NOT available to starving people.
Or have you seen an african kid eating GE rice/corn/wheat?
