I don't know for certain, but I don't think that the atmosphere is thick enough to make a fan cost-effective for the weight that would be required. A small pump and resevoir might be able to take that thin atmosphere, compress it and blow the dust off the solar panel. If this were possible, the air nozzle could even be mounted on an articulated arm so that it could clean dust off almost any part of the rover.
As an Naval Electronics Technician in-training, I can tell you we still work with 70s era tech to help build basic skills and understanding.
Two main reasons:
That stuff is tough! I've seen logic circuits easily withstand twice the rated voltage and current.
It's big. Even the most unsteady-handed person can solder with little fear of shorts or cooking components.
It's been a while, but if I recall the details correctly from school, screws with fewer, larger blades are more effecient WRT raw thrust but don't tend to last as long due to cavitation effects which are also very noisy. A screw with a larger number of smaller/thinner blades would last longer and, more importantly for military craft (especially submarines) be much quieter. This also looks somewhat similar in concept to the screws used on the new German 212 subs.
Also, unlike a phone call/message, email can contain pictures, drawings, etc.
Yes, I realize that that you can fax images but, having worked for a building supply company, an electronic image that doesn't get lost, crumpled or have coffee spilled on it is often much more convenient, especially since all of our ordering and pricing was done on computers.
For the sake of personal interest:
If photons don't have mass, how is it that they are affected by gravitational fields?
And for the sake of unsubstantiated theories:
What if the classic E=MC^2 curve were, in fact, one half of a symmetrical curve? If one could *somehow* cheat and skip over the infinite energy/mass bit, then your energy needs would decrease dramatically the more you accellerated beyond the speed of light.
Please note, my knowledge of physics come from half-remembered high school classes. In real life, I am an Engineering Technician.
Everybody wants wind power (but not in their back yard) That's one thing that I've never understood. I used to live about an hour's drive from a wind turbine and drove by it several times a day. I could never wait to drive by because I loved the sight. My new home is very windy and could benefit greatly from wind power. I simply cannot fathom the resistance to wind turbines.
One thing I have always wondered though: given the fairly large surface area of the turbine blades, would it be possible to add a photosensitive material and pull a bit of power from the sun too? Probably not terribly practical at the moment, but I seem to recall reading, probably on/., about a paint on solar panel.
They were much cheaper because there were no 'copyright subsidey' fees tacked on to the price. The damned things were so illegable that you could, in no way, violate someone's copyright. ^>^

I actually have a huge problem with Blizzard's distribution system for patches. My ISP shapes their traffic and it can take hours for a small four megabyte patch to download. If I go directly to their site and download as a standalone file: about a minute. A distributed download system is a good idea both for Blizzard as it saves them bandwidth and for most of their customers as they get their patches faster (especially when it comes to large patches), but the standard download model has to be available for those who cannot use this type of system.
Because when I drive anywhere with others in the car, we all sit silently and never attempt conversation, just on the odd chance that the small amount of attention used to hold a conversation will be needed for a task that is, after a few years of practice, so automatic as to require little conscious though.
But with the basic hardware, it'll be great to load up a legacy OS and play those games that don't work in XP/Vista that I (and many others) still love.
They may be doing so legally, but that is not what the rule cares about. Then that is what the rule should have said.
I'm not saying I disagree with you, the intent of the rule is quite clear, but (un)intentional poor wording can lead to a big mess later on if someone decides it means something different than the authors thought it did.
After looking at your previous comments, you deserve a -1. If someone with an axe to grind flagged you unfairly every time you made a post, then you'd have a legitmate complaint, but making inflamitory posts and getting labelled appropriately is rather reasonable I think.
Attack and stealth reconnaissance helicopters frequently fly and hover very low to the ground to remain hidden. I can't speak to the odds of hitting one, but I think it might be possible, if unlikely.
But if most everyone thinks it does, it might as well. After a quick survey of my immediate associates (about 15 people, so not a statistically large sample to be sure), the only one who thought 'begs the question' might be correct is the only one in the group that hasn't graduated high school (a 17yr old). As far as your actual attitude regarding language, I say to you: "You're right because clearly cabbage soppy wankel ebbeh gruntsponge." ^>^
One of the reasons that current space suits need waste storage systems is that the acts of donning or removing the suit takes several hours by itself. If you've got a 3 hour job to do and it takes 3 hours to put the suit on and take it off, that's 9 hours. Most people can go 9 hours without using the bathroom, but it's not likely to be very comfortable by the end. If this suit takes only minutes to put on or remove, you don't need to plan spacewalks as extensively because it's not a major inconvenience to come inside for a few minutes to take a break and in the case of a real emergency, well, suck it up like the rest of us have to do on the ground.
Damn kids, off my lawn, good old days, etc.
But seriously, dude, I'm younger than you are and I wouldn't hesitate, so it's really down to personal perference.

What about KARRs, the evil versions of KITT?

A pet store.
You walked right into that one.

The article stated that they tried this treatment on Schiavo but with no effect.

Ditto, I remember using Win3.1 on those state of the art PS/2 - Model 80s back in my school days.
