This is the way needed to go to make traffic safer, and it's a natural progression with the systems we have now.
We already have collision avoidance systems in production cars today that help with braking to minimize injuries on both other cars and pedestrians. Using radar and cameras with image detection. Adding a communication channel where the computers in the cars can make other cars aware of their status is one of the next steps.
You're wrong about the prostitution law in Sweden. It's illegal to buy sex while it's not illegal to sell sex. The reasoning is that the prositutes are concidered to be victims.
At least one could imagine that something like dew of some sort of molecule could form on the solar panels during the night when the temperature falls. Droplets of this could then coalesce and fall off the panels taking dirt with it as water droplets on Lotus leafs.
I don't know anything about the materials on the outer layer of the panels and what molecules would condense (CO2?) on it though, and what type of interaction one would be able to expect between them.
Provided that the behavior is linear, of course. But it's great to know that the experients are happening; I know a lot of planetary geologists who are looking forward to better lab data.
Acctually, we published data recently in Journal of Geophysical Research - Planets about the effect of photons on water ice films, don't know if the quality of the data is good enough for the geologists though.;)
Also, lab work on ice at these temperatures and pressures would help a lot. Although it's hard to figure out what ice will do over the course of 4 billion years...
We're doing lab work on this already. Here in the lab where I'm sitting now we study non-thermal crytallization of amorphous water using photons.
Setup is a vacuum chamber with 10^-10 torr pressure and a cryostat able to cool the graphite sample to about 40 K.
The amorphous ice on the sample is irradiated with photons from a laser or a lamp and the crystallization that this processing induces is studied. The same thing can be studied with electrons, ions, or some other specie. The rates can be calculated and one can do simulations on how the ice should look after 4 billion years.
Certainly. Sapphire is a crystal form of aluminum oxide and it is quite transparent. For example it doesn't absorb ultraviolet photons close to the visible spectrum which make it a suitable material to have in the windows to my vacuum chamber when I want to shoot UV laser light in to it.
An object doesn't have to strike it to break up. If a comet or such come too close it can brake up just because of the gravitational forces. The Shoemaker-Levy 9 comet was a good example of this process.
Surely with the multitude of molecules there would be some other that would cause such a re-arrangement.
It is known that adsorption of molecules and atoms, not only water, on surfaces can change the surface tension of a material. The changes can lead to re-arrangement of the top most atomic layers giving different different crystal structures than in the bulk material.

I, for one, welcome our new Dark Age overlords.

As your link states, the Sea Shadow is a test craft. The Visby corvette is going to be in active service in the swedish navy.

Ok about sensors that detect ice build up on aircraft, but what about detection of the elephants that acctually make up the clouds?
