At which point the jammers switch to the new frequencies and or up the power. The problem with jamming is that it is on the side of the jammer. It takes a lot less power to jam that it does to break through the jamming.
So if the blue car comes into view, maybe the lasers will not see it (I still don't get that part, can't the lasers find range?)
I've been thinking about this and I have a possible answer. Most, if not all, lasers used in rangefinding are some form of red. A blue car does not reflect red light (or at least not enough red light) and if you took a photo of it with a red filter (only allowing red light to pass through) it would appear black or very close too it. So basically, the lasers that are being used don't reflect off the blue cars and so it appears that there is nothing there (a no return is considered "clear"). So the problem comes down to improving the sensors used, which is relatively cheap and trivial in the long run compared to the software development involved.
A number of cars use both lasers and video cameras and analyze the picture from the cameras. However, some are relying more on lasers than cameras (easier to process laser information). I'm not sure, but some may not be using any cameras at all.
Have you ever thought that the heavy sentences for murder are what keep the recidivism rate low? After all, it's kind of hare to commit a second murder while in jail.
Also, as you say, vast majority of murders are by people the victim knew. Ever think that the heavy sentences keep others from committing murder?
Sentences are for multiple reasons. Rehabilitation, Punishment and Deterrence. Rehabilitation so the person does not do it again. Punishment for their crime. Deterrence to keep others from committing the same crime.
Geez, at least give the full quote for context.
"Essentially, you don't want to use a billion dollar DDG [guided missile destroyer] to suppress pirates," Work said. "That's a mission for a much smaller ship. But we have a lot of ships in that area because of ongoing operations in the Horn of Africa. These are ships designed for high-end war fighting, not chasing pirates." Using a DDG for this is like using a pile drive to crush a beer can.
I doubt you'd be able to disable all services without going through a roundabout way of posting to the internet. Last I heard, browsers had exploits. Hell, even drivers, such as your ethernet card, could have drivers. Remember the old Ping of Death?
May I know how exactly they are going to get through my OpenBSD firewall and implant a trojan on my FreeBSD desktop? I'm a bit confused... What makes you think they haven't already?
"an email from Attorney Jack Thompson stating that his 15-year-old son purchased the Mature-rated game BioShock from a local Best Buy."
Me thinks Jacko may have made a bit of a mistake this time. Last time I heard about someone doing this, it was a guy who dressed his 14 year old daughter up and made her look over 21. He sent her to a bar who's owner he hated to get the owner in trouble. The judge took one look at the case, threw out the charges against the bar, and had charges filed against the parents for contributing to the delinquency of a minor.
Here's to hoping a similar thing happens in this case.
As long as the US, which is by far the largest source of CO2 on a per capita basis, is doing nothing to curb emissions it is rather hard to put much pressure on China to step up to the plate.
Tell you what. Calculate CO2 per capita based on where the consumers are and not by where the producers are and then tell me that. The EU has essentially been exporting its manufacturing to the US and China. Except that in China more CO2 is produced per product than when it was in the EU due to the lax environmental regulations and lower factory efficiency.
Try flying ANA. Best airline food I've ever eaten (vegetarian meal; the corpse-eater one looked like it was only nice if you liked things with tentacles).
Except the SDI plan uses a much more focused laser than this is likely to be. 10MW over a 10m diameter dish comes out to ~125kw/m^2 "merely" 100 times more than the sun. Most microwaves generate at least 9kw/m^2, so this is about a 14kw microwave instead of your regular 1kw. The SDI focuses those multimegawats into an areas less than 6 inches in diameter. A power density a few orders of magnitude greater.
Distance to Moon: ~238,000 miles
Distance to Mars: ~95,000,000 miles at closest approach
Further, there were flybys and landings before hand.
On July 19 Apollo 11 passed behind the Moon and fired its service propulsion engine to enter lunar orbit. In the several orbits which followed, the crew saw passing views of their landing site in the southern Sea of Tranquility about 20 kilometers (12 mi) southwest of the crater Sabine D (0.67408N, 23.47297E). The landing site was selected in part because it had been characterized as relatively flat and smooth by the automated Ranger 8 and Surveyor 5 landers along with the Lunar Orbiter mapping spacecraft. It was therefore unlikely to present major landing or extra-vehicular activity (EVA) challenges.[3] http://en.wikipedia.org/wiki/Apollo_11
Doing any kind of heat based power generation in space on a large scale is pretty much a complete no-no.
Which is why they are doing solar photo voltaic and not solar thermal power generation. No heat gradient required. However, you can still use mirror to focus the sunlight onto a smaller panel to increase electricity generation.
Unfortunately, all the new power generation technologies suffer from the same problem - they are all much more expensive than fossil fuels, so fossil fuels win every time,
Which is why companies do some development before hand and don't do a crash program to replace the older fuel sources. They figure out if it will work, what most of the problems are and what the challenges will be, then wait until it is cheap enough to start full scale deployments.
People here keep claiming that the more intense sunlight will result in high power generation, but i'm skeptical of this.solar cells here now aren't capable of extracting more then 35% of the light that makes it to earth now, so they won't do any better in space.
On earth, you get ~250w/m^2, is space, you get 4-5 times as much. So, a solar cell in orbit at the same efficiency will produce 4-5 times as much power. It's not that they are more efficient, it's that they are getting more sunlight->more power.
the only type of solar generation that will produce more power in space due to the more intense soalr rays will be some form of mirror heating, and that present a whole bunch of other problems.
A) not it isn't. B) Such as?
i'm also curious as to how they will keep the solar array in a sationary orbit? if it's not, you will still end up with the problem of night time
A satellite in orbit will receive 100% of the sunlight for a far greater period of time than a satellite on earth. Further, a satellite in orbit will receive light for well over 70% it's orbit. So, put a couple satellites in geostationary and just point a few of them sideways. Enough sufficiently spread out will allow you to cover your base load at night as they will be in the sunlight even if the area they are beaming to is in night. This is the same way the moon reflects light to earth for 99% of the time, albeit the moon is a lot further out.
There's more important hurdles to get over before we do anything like this. namely making exiting the earth's atmosphere cheap and safe
It doesn't have to be cheap, just cheap enough to make it worthwhile. As to safe, we are shipping up a machine. It just needs to get there. Also, once a proof of concept is done, then all it takes is to wait for delivery to get cheap enough and it will be done. One might as well test it prior to it being "cheap enough" to see if it is worth while.
The DC area has two HOV lanes that are physically separated from the rest of the interstate. They go into DC in the morning and out in the afternoon. There is no 'carpool lane' that is immediately adjacent to the regular lanes.
The big problem, is that over the years the HOV lanes have been shrunk from a minimum of four people per car to a minimum of two people. This has caused an increase in traffic on the HOV lanes, making it take about as long in the HOV lanes as the regular lanes, eliminating the reasoning behind the HOV lanes entirely.
ABC is NOT providing "High Quality" video. What they are providing is a lower quality video that is below TV resolution and framerate, containing bluring and blocking that would not be considered acceptable by any TV station. It is not even up to VHS quality.
Further, you did not even look at the requirements of providing two different services off of the same connection which, as I mentioned, would require at least a small amount of packet shaping to keep segregated.
You aren't watching TV off of NBC or ABC.com, you're watching videos that buffer on your PC. TV over IP is what Verizon is offering on their Fios networks and uses at least an order of magnitude more bandwidth. UDP packets delivered across the ISPs network to the decoder box to the TV. It requires constant latency. As such, the setups are made so that you have your internet and your TV running off the same line, but even if you aren't using the TV, you aren't getting access to the bandwidth the TV had. It still requires packet shaping to block off bandwidth specifically for the TV.
TV over IP. Say you're getting TV from your ISP and they both use the same IP connection for both internet and TV. The TV connection is going to require it's own dedicated bandwidth which, unless you know of a few methods I don't, would require some form of packet shaping.
I'm pretty sure regular cloth is not going to stop it. Cotton wool and nylon don't stop, or really even attenuate, radio waves. Metal and water, do. The water in your skin's outer layer is what this is affecting and how it is causing pain. So, I'm pretty sure a burka isn't going to stop anything from this device.
Escalation is the point. There are now more nukes.
Exactly what do you mean by "there are now more nukes"? Looking at the total number of nuclear weapons in the world, that number has been going down for roughly 15 years or so. The U.S. stockpile has been steadily shrinking for that time as well and still is. The number of nuclear countries has been going up, but that has been outside of U.S. control.
Or do you mean more nukes pointed at Iran or something else?
Also, contrary to popular opinion, the U.S. does not have more nukes than anyone else. That still belongs to Russia and has for several decades by several thousand warheads.

i guess the percived threat from the USA was why russia developed them.
Actually, the Russian nuclear weapons program started during WWII, just like the USA's.

Not any more. Carter's idiotic presidential order was overturned by the present Bush's presidential order.

I dont have a dogmatic bias against Nuclear - if it can be done economically and safely, fine - if not, and history so far is against it, why do it?
If you list every single problem you have with Nuclear Power Plants I will address each and every single one that I can.
You missed one other source of power loss. Capacitance in the wires. Estimated total transmission loss in '95 was 7.2% according to wiki. http://en.wikipedia.org/wiki/Electric_power_transmission#Losses
