You forgot about lift. If you shape yoru baloon in such a way that it produces lift if it has forward momentum, you can get around the drag. You start at say 100,000 feet with zero velocity. You turn on your ion engine, and accelerate to a few fps. Yes you have a big drag area, but you also have a big lift area. You use the lift to move higher than the buoyant force can move you. As lift brings you higher, you accelerate, because dynamic pressure will remain a constant (so that drag cancels out thrust and you still have net lift) The only problem I can see is that at very high altitudes you have rarefied gas dynamics and effective temperatures of the air is very high, so you need to have some sort of TPS even if youre moving very slowly. Its worth a shot to try it though.
Just design it so the wheel cant lock up. Have it powered by a ratchet system (think bycycle) so that when power is not applied the wheel still spins. Thus if the engine locks up all that happens is that you roll to a stop. You could theoretically push it when the engine is off with this system. A better way to lock the wheel up is by braking (going into a skid) so antilock brakes are a must.
I worked at the Univrsity of maryland's Space Systems Lab, where the Ranger Robot has been developed. They basically have been working on this robot for the last 13 years, and they have a working prototype in the lab. The prototype is designed to work underwater, since the SSL has a Neutral Bouancy facility, so the difference between the prototype and the actual ranger is that it has no rocket thrusters, only fans. But other than that, the robot is fully functional, and very capable. Back when I workedthere I helped design a test where it would put together parts of the James Webb Space telescope, and it worked perfectly. If any robot is qualified to fix hubble, ranger is.
So sew slower. Its stab resistant because presumably the kinfe is moving quickly. If you move it slowly, the liquid remains liquid. If you sew it by moving the needle slowly you should be fine. Actually I think the article mentions that the kevlar fabric is impregnated in the kevlar fabric. So you could sew the kevlar fabric ahead of time then just soak it in the liquid.
Yes, user friendly is code for "accessable to people who are not computer literate" somone who is not computer literate will use a more friendly to use computer operating system. Which, while it may be secure, will have flaws, since no system can be 100% flaw free and still grow. (if you fix the features of a piece of software, you can approach perfection, but even the software to run the space shuttle had 4 bugs in it) As more and more people use the software, more and more non literate eyes are looking at it, and not adding to the software (if it is open source) but they are finding flaws in the software, they just arent doing anything about it except maybe complaining to each other. As the number of newbies reach critical mass, some malicious user will exploit one of the flaws in the software, making use of the gullibility of those who use said software, reducing security.
To see the best view in the solar system: Earth from LEO. How many people pay millions of dollars for their house to be on the ocean, or on the side of a mountain, or on a lake, or near central park so that it has a good view? the view of earth from space is about a billion times better, because you see the entire planet, and its always changing. First you gt tourists wanting to see it, then you get real estate developers, because people will want to live there, just for the view.
Or instead of investing in 4 things that each need to be accomplished in order for cheap space solar power, we could just sink our money into fusion research, and probably accomplish the same thing alot sooner. (and more efficiently). Current fusion technology has reached breakeven in terms of power generation, and has been increasing power generated by fusion reactions by an order of magnitude a decade at least.
When the bomb went off, you could actually see the bones in your hands from all the X-rays that were emitted from the bomb. True, but not for the Reason you stated. I dont care how bright the light is, you cant see X-Rays with your eyes. however, with a sufficiently bright light your hand becomes translucent and you can see the outline of your bones. Try this: With a very powerful flashlight (like a Maglite) go into a dark room and let your eyes adjust for a minute or two. Then hold your hand so the palm completely covers the flashlight part, dont let any light escape. Turn the flashlight on and you should be able to make out the outline of your bones, if the light is powerful enough. But you still cant see X-rays.
$5 says that this was an intentional leak on microsofts part. Its not the whole source, so theres no real danger to microsoft, but there is a significant danger to the open source community. Look at what SCO has been doing. How long before microsoft claims that some of its IP from the "leaked" code is in linux, and starts suing? Everyone in the OSS community needs to be super careful not to get tainted by looking at this code

Tanks were a force multiplier, the same number of cavalrymen could take out a much larger amount of enemy. Army vs Army battle has always moved towards more standoff weapons since the invention of the bow and arrow, Im talking about post invasion occupation. Well always need the infantry for that.
So couldnt you easily defeat them by disabling one, getting it to send out a distress signal and then blowing up the "swarm" when it appears? Or you could just use a giant magnifying glass.
no, because you cant occupy a country with robots. You need people on the ground, working intelligence, getting among the people, all that hearts and minds stuff you hear so much about. Making friends with the natives can NEVER be done by robots. Plus not all the natives are friendly, so there will always be a need for the infantryman or MP on the ground in the streets. Robot armies might be good against conventional armies, but they suck at human to human contact.
Because this means that the more guilty you are, the more stridently you demand privacy! Only freaks far from the norm of society want privacy! Im calling John Ashcroft on all of you.

Not until I get my flying car. And talking dog. And Judy Jetson.
Q - XPrize - will it succeed in bringing CATS, How did SpaceX get Navy contract?
A- Hopefully not, unless you want all our base to belong to them. To answer the second part, we took off every zig for great justice.
Not even for Bruce Willis and Ben Affleck?

Read Starship troopers by RAH, no not the movie, read the book. In the book he basically says exactly the same thing you do.
