A form submit hack to an open document is not illegal nor in my opinion, unethical. You are simply choosing a different way than intended to view open information. Kind of like reading the last chapter of a book first. Suppose that someone posted links containing the get statements to a web page and called it something along the lines of "Get your Harvard Info Here." This page could appear to be totally legit while totally screwing the people clicking the links. I think that this is a total over reaction on the part of Harvard.
Not quite. Most modern oil fired naval boilers use 1200 psi superheated steam. The saturation temperature of water at 1200 psi is approx 567F. The temperature of a superheated steam leak quickly drops to saturation temperature due to expansion upon leakage. As you can see, this would not be enough to ignite a piece of wood outright. FYI, all naval nuclear power plants use saturated steam cycles as there is no way to superheat the steam using a pressurized water nuclear reactor as designed. When on leak patrol, I used to use a fat bladed table knife around flanges and valves. Look for the fog, man!
Well, fossil fuels are pumped from the ground, burned, and the combustion products go into the atmosphere with no way to to be re-fixxed into the underground petrol, thus producing an open loop (bad) Carbon cycle. The combustion products of plant derived fuels are re-fixxed into succeeding generations of plants thus closing the loop (good) with a zero net gain of Carbon into the atmosphere.
Of necessity flywheels have a high moment of inertia (heavy near the rim). This added weight creates more load that needs to be lifted. In addition to this, the AoA cheat wouldn't work unless you had a very large flywheel and some kind of transmission to meter the energy to the rotor over the required flight time.
As an experiment, hold a sheet of plywood flat while spinning around in a circle. When spinning as fast as you can, change the angle of the plywood to about 30 degrees and see how fast the drag created by the plywood bleeds off your energy. I think you'll find the results interesting.
Free thinkers... Music majors... That goes a long way towards explaining why EDS has gotten itself soooo hosed in the NMCI project. Free thinking is fine if tempered with just a bit of knowledge and experience.
I am in the SCA and frequently take the time to relax by beating the shit out of my friends with a big stick while wearing armor. You have no idea how cathardic it is to fight legally and then have a beer with these same friends afterward. It has helped me maintain my sanity at work, as it allows me to act out my hostilities towards my co-workers without actually killing any of them.
I work for the government and I'm here to help you... Really!
if you used superconducting magnetic bearings and ran it at low speeds to negate wind resistance, the only real energy consumption comes in the form of rolling resistance (friction) and changes in altitude (potential energy). Potential energy can be recovered by going back down hill. So, if you're assuming a perfectly efficient engine (impossible) you simply need to equate the heat content of the fuel with the product of the friction and the distance traveled. Solve for distance, and there you have it. BIG NOTE: This problem is typically contemplated in highschool physics as it has little basis in reality.
40 miles each way, to and from work, 50 weeks a year (2 week vacation), with a 500ft altitude change and see what kind of milage/reliability results the bloody thing gets. My guess is that it wouldn't last a week before some major malfunction. Optimization in one area often degrades performance in others.
Back in the day...(Waxing Poetic) when I was working as a mechanic, I was required to purchase and maintain my own set of tools. The cost of these tools, over about 5 years of accumulating most of the tools I needed to do my job, came to well over $15k. How would being required to purchase your own computer workstation be much different? I never really thought about it like this before, but it is interesting nonetheless.
I know guys that would cook chickens in front of the antenna arrays of shipborne radar systems. A bit more power, to be sure, but it just shows that radar is not something to be taken too lightly.
I am aware that they are EM waves. So is gamma radiation. The question how much power per unit area (flux) are they using to see you behind a wall and how does that flux interact with your body. If it is being used in an imaging process to see your body, you are either absorbing it or scattering it in such a manner that it can be read by the instrument on the other side of the wall. I should think that this non-line of site imaging would require slightly more power than your average x-ray machine. As far as the x-ray stuff goes, I actually found a tech that knew the answer to the question. It happened to be approx. twice as much dose as I recieved in a year of operating a submarine nuke plant. So, there you go.
What the radiation exposure to people on the other side of the wall would be. Operators of this type of equipment rarely understand the implications of its use. Just ask your xray tech what your equivalent whole body dose will be next time you get a chest xray.
Maybe I gave you the wrong impression. This is not a rampant problem. He is 14 and interested in girls. I have confronted him and asked him what he thinks would happen if his mother found this material on this computer instead of me. I have told him to stop, and he has, for the most part. Where the problem is now is that my kids like to surf the gaming sites and they are bombarded with popups and banner ads for adult material. Granted, the images are generally of thumbnail size but inappropriate nonetheless. Hell, my daughter and some of her friends were entering their names in a search engine and ended up getting naked pics of girls even with the filters turned on. This is the type of problem I am seeing. As far as the disabling of the network. He may or may not actively try to get around this in the future. I was merely referring to his ever increasing knowledge of how computers, and the like, work.
I have installed two different filters on my kid's computers and I still find porn in my son's cache. Whether Linux or Windows, to date, the only filter that realy works 100% of the time while I am not at home is to disable the lan connection to the internet. It's only a matter of time until he figures that one out too.
Let's see... Isn't amature radio is still faster to set up and can cover greater distances than cellular technology? When I say "greater distances," I mean on the order of thousands of miles. Wide area cellular is dependent upon far more infrastructure than amature radio and I think it would prove to be less reliable in a truely large disaster.
Interestingly enough I do exactly the opposite. I use KEDIT on Windoze as my main dev tool. Unfortunately it has not been ported to Linux. Samba and Putty are also indispensable tools for me as they allow me to directly save to and run programs on remote Linux servers.
The armor piercing projectile from the 16" guns on an Iowa class battleship deliver approx. 1.6x10^8 Joules of energy to a target 24 miles down range. This calculation does not even take into account the high explosive in the shell. The aftermath of these little babies leaves plenty of debris lying about the place. Nothing like the solar furnace you describe. You can check my calculations if you like.
impact energy will be SO HIGH that they will vaporize everything they attack ergo no residual debris, waste, chemicals or ash
Really? I find this interesting. Just where do you think everything will go? Hit something the size of an apartment building and you will not "Vaporize" everything into nothingness. The residents of a small town in Oregon found a dead whale washed up on their local beach. The whale was too big to be easily moved so they decided to blow it up. Sounded like a good idea at the time. Long story short, they only acomplished blowing rotting whale flesh all over the place. Check it out: Here Moral of the story: Blowing shit up does not necessarily get rid of it.
The impulse delivered to a projectile with a rail gun can be spread over a longer period of time, thus allowing more sensitive electronics of steerable munitions to survive launch. I think these munitions would be the logical next step of such a weapons system. The best target riffles fired from fixxed platforms are just capable of sub minute of arc accuracy. With the pitch and roll of a ship coupled with atmospheric effects, I should think that this weapons system would be very hard pressed to maintain MOA accuracy at range with conventional munitions. Keep in mind that a minute of arc at 250 miles is just under 384 feet. Even with a downrange spotter it would be extreamly difficult to hit the target at which you are aiming. So, here we are back to spending more for smart munitions to get the job done without wiping out a whole town/village. 'Tis all fairly silly.
I'm not sure where H2O2 came into this conversation, but it does not supply free Hydrogen. H2O2 is an oxidizer that supplies water and a free Oxygen ion to a chemical equation. It would require energy (endothermic reaction) to separate it into H2 and O2. That would be a little difficult to power your laptop off of that particular reaction.
I'd go with the TI-89 for x-treme calculus. I can do calculations on both HP and TI calcs and I find the TI-89 to be generally superior to the HP-48GX. I have not, however, tried the HP-49

Every person on board wears 2 or 3 hats. Their rating, supporting the maintainence for the equipment required for their rating, and damage control.
Yah! Sitting 12 hours of freeze seal watch is tons-o-fun
Right on... The only real 'extra' people are the non-quals that are just breathing and taking up space.

100% efficient being defined as what energy you put in you get out as mechanical energy
Something like that WWI French aircraft where output was controlled by turning the ignition on and off. Pray that sucker comes back on...
