Ok, I know you are joking about radiators here, but there are other forms of water cooling modifications that people really do on cars.
Air-to-Water intercooler:
Cools the intake air after it has been compressed and heated by a turbocharger. As opposed to Air-to-Air, which is much more common. They both have their advantages and disadvantages.
Water or CO2 IC Sprayer:
Cools the outside of an air to air intercooler by spraying it with water. I believe the STI's come with wter ic sprayers stock. CO2 sprayers used compressed CO2 resulting in a drastically lower intake temperature leading to denser air, and more power.
Water/alcohol injection kit:
Spraying water, or a mixture of water and alcohol into the intake, to cool the intake air, and help prevent detonation or engine knock.
Nobody has done this because someone would come along and create a program that splits up entire hard drives into attachment size pieces, and mails them to their account for a free online backup drive. You gotta set a limit somewhere.
It's madness that each lightbulb will have to contain it's own little transformer - it'll make the bulbs vastly more expensive and wasteful.
Sorry, I don't think you'll see a change(at least not to a lower voltage) in your wall outlet's voltage any time soon. Maybe a transformer in every light bulb seems wasteful, but take into consideration that led's can last roughly 100,000 hrs as opposed to 1,000 for incandescant's.
Still seems wasteful?
Transformers don't have to be huge, especially if they are powering an efficient device that doesn't draw much power. Disposable cameras contain transformers in them that step the voltage from 1.5 to 300 volts, and they are pretty damn small. In fact you could fit a transformer into just the metal base of a normal incandescant bulb. Not to mention the transformer's solid state cousins: voltage regulators, swithcing power supplies, and probably some others I don't know about (IANAElectrician.)
In fact, you could also scrap the idea of stepping down the voltage entirely. How about putting more led's in series. Think about it, led's emit a narrow spectrum of light, so to smoothen out the spectrum, you might want to add a bunch of led's from different parts of the spectrum. Just put 40 little 3v led's on a board and voila, you have a device that accepts 120 volts. Another reason to use a large number of leds: you might want to spread out the surface area where the light is coming from, a single point of light could seriously mess with your vision. Not to mention the fact that I doubt to see any single led in the near future that can output the equivalent of a 60 watt incandescant light bulb.
But the thing the I wonder about is if and when the standard plug model will be changed to a model where the socket and the plug contain coils to transfer the power, like an isolation tranformer that is split into two parts.(Have you ever seen how a sonicare toothbrush charges itself?) The main benefit I see in this is safety; never have any exposed wires to fry yourself with. Actually, if all your wall sockets had coils in them, the plug of your device could determine the voltage that device receives, simply by the nuymber of coils in it. Again, IANAE, so I don't know, maybe it would take the advent of room-temperature superconductors to make this idea feasible and efficient.
Wow, I got really lucky taking it last year...
Not sure where they got their information from, but I took the C++ AP exam 5 or 6 yrs ago, and the year before that I took the Pascal exam.
Sorry to say this bro, but like so many other slashdotters, you haven't gotten lucky yet.

Yeah, except the bitches might take offense to a name like that.

When it "flies" into the upper left corner a camera flashes, and the string becoms visible for a brief moment.
The movement of the helicopter is so obviously swinging from a line.
You don't even see it take off from the woman's hand or land for that matter.
Let the time traveling begin!
