Ramming is a bad idea. Even if you can crack the ice, you'd be pushing the cracked blocks against each other, forcing them together and giving them the chance to freeze together. They can't go anywhere, you're pushing against the entire ice shelf.
What you need is a force in the direction where the ice is thinnest and weakest, i.e. vertically, which is just what an ice breaker does. It forces the ice down, and pushes the loose blocks underneath the ice shelf so they won't fill up the channel.
I've tried cracking ice by applying heat to it: I regularly dunk ice cubes in hot tea. While the cubes will crack, the cracked cube stays together instead of separating into smaller pieces.
The remote is going to be the difficult part, especially if you want to choose playlists.
I've recently bought an iPod nano 6G and found it unusable in my car: the touch screen means you have to look at the device to operate it, and I'm not going to do that while driving. So I bought an iJet Nav remote with physical buttons for pause, next track, and previous track (also volume up and down, but those are not necessary in my setup). This gives me enough control for the things I want to do while driving, and the pysical buttons mean that I can operate them without looking.
The Nano 6G will operate with the iJet Nav attached for about 5 hours on battery power.
Choosing a different playlist is going to be way too distracting however you set it up. The only acceptable option I've seen is an iPod linked to a car stereo through the CD changer input. Dension (I think) makes a device that will do this, and it will map 6 playlists to the Disc 1-6 buttons on the car stereo, so choosing a new playlist is a matter of pressing one button.
I think you'll have to plan ahead and have an appropriate playlist cued up before you take off.
There are a few reasons. Celestial mechanics is a big one: Voyager 2 took advantage of a rare planetary conjunction so it could visit all four of the gas giants. The next chance to do that is in something like 150 years. Most of the time you'd be spending $$$ on a fly-by of one planet, and that money would be better spent on a mission that can orbit that planet instead. So instead of Voyager-style craft, you get missions like these: Cassini-Huygens: Saturn and its moons Dawn: Vesta in 2011-2012, and Ceres in 2014 Galileo: Jupiter and its moons Juno Spacecraft Mission: Jupiter-bound for polar orbit in 2016 Magellan: Venus orbiter Mariner program: Venus, Mars, and first to Mercury Messenger: Mercury New Horizons: Pluto and its moons in 2015 Curiosity et al: Mars
Having the probes act as relays won't work when you launch them at 10-year intervals. After 10 years, you need a 26-meter antenna or even larger to communicate with the probe. It would also require the probes to be sent out in the same general direction, but 10 years later the planets will be in different places. Again, no planet to visit=expensive space relay.
The Pioneers and Voyagers were hugely important as a first step, but they raised more questions than they answered. At the same time, they provided information that was necessary to design probes for the environment they'd find at each planet. The extreme radiation of Jupiter for example. NASA is using that information and methodically answering those questions by sending probes to each individual planet for more detailed observations than a Voyager-style flyby could ever make.
Once the Voyagers are truly outside the solar system, the data they'll yield then can be used to create a new mission to follow the Voyagers out of the solar system for more detailed observation of that environment.

I know it looks cool and all, but does it offer an advantage over your typical injection-moulded plastic case? I've had a couple of Dell laptops, and they all twist noticeably when you pick them up by one corner. If you drop them, the frame flexes and transmits the stress on the motherboard. I broke one by having it drop from 30 cm. The alternative is Apple's milled-from-a-block-of-aluminium case. It feels more solid, and I expect it does a better job of protecting the internals. Carbon fiber is strong in both compression and tension, but is much weaker in bending. It's also brittle. So how well would this material work as a laptop case?
Hollis: I'm starting a foundation, because if I hold onto all this money, I start to look impolite. I want to find a single problem I can attack, something which might actually have some kind of substantive effect. Maybe I should be fighting AIDS in Africa. Maybe it's malaria. Could be clean air or election reform. I don't know. But my sense is that you would have a unique perspective on what that could be and how to make it happen.
CJ Cregg: A single problem.
Hollis: It's a complicated question...
CJ Cregg: Highways... is what you're looking for.
Hollis: Really? It's not sexy.
CJ Cregg: No one will ever raise money for it. But nine out of ten African aid projects fail because the medicine or the personnel can't get to the people in need. Infrastructure's the problem. Blanket the continent with highways, and then maybe get started on plumbing.
(later on, CJ refers to this conversation as "Frank Hollis wants to give me ten billion dollars to fix the world")
Incorrect. Grammar (syntax by any other name) is what keeps tripping me up when I get started on one of my occasional forays into programming. I just don't do it enough to get fluent, so I keep mixing up my $ and @ and {} (actual examples from a recent XSLFO project).
It seems that the USA has become the neonazi military regime. It barely worked in Korea, failed miserably in Vietnam and hasn't even got started yet in Iraq or Afghanistan.
Actually it worked brilliantly in Iraq. The Iraqi army, war-hardened and no slouch, was blitzed in a matter of days. Any regular army would fare badly against the US. The problem the US keeps having is that its opponents aren't regular armies but guerilla fighters. Vietnam, Iraq, Afghanistan are/were all insurgencies, and you can't win those if you're not prepared to kill everyone who opposes you, and even then your tactics will ensure that plenty of formerly neutral civilians will resent this enough that they'll take up arms against you, so you get caught up in a vicious circle which doesn't end until everybody's dead or you give up.
The Russians with their cheap, plentiful warplanes wouldn't have fared any better in these circumstances (case in point: Afghanistan), because your weapons basically don't matter in an insurgency.
Spend an extra $60 on a better HD that has capacity to better meet your growth.
No. Buy a HD that is large enough for your current situation + 1 year, then spend the $ 60 next year (or whenever you run out of space) to buy a HD that's much larger than you can buy now.
Also, 6 years is a long time for a harddisk. Based on past experience I've started to replace the HD preventatively every 3-4 years.

It's ideal for people who don't know what size they wear (like me: clothes shopping is infrequent enough that the information tends to get lost). Saves me from having to try on different sizes.
And here we've arrived at the big drawback of this system: you need more parameters than just the size info on the label to determine whether clothes will fit. Considering the inconsistency in label info between manufacturers, it's going to be a pain to get all the info you need.
On a related note: how does one manage a list like this, e.g. when on the hunt for books at the bookstore or library? I've got some index cards with a list of books/authors I want to read, but adding the negatives would make for a large and unwieldy list.

That doesn't sound right. Fiberglass is usually done at much lower pressure. Heck, fiberglass moulding can be done without applying pressure at all.
Also, 600,000 tons on a bathtub is a ludicrous amount of pressure. That's about 300 GPa, or about the pressure in the center of the earth.

If you implement AV out via USB, the host must contain a processor. Then you can't just jack your iPod into a car stereo or TV anymore.
USB does not include analogue video and audio outputs.
