For a car, fuel costs are some half the total maintenance. That's a design that was improved in the last 100 years, and that supports the research and design costs over tens of millions of cars yearly.
I'm surprised the fuel costs only $2000, but I'm not surprised at the cost per seat - this considers research and design costs for maybe a dozen units built, the costs of the base (buildings, transportation related to the business, storage tanks, and what not else), the employees costs (including taxes), the maintenance of the space vehicles, the (probable) hundred flights or less per rocket, insurance for bad things that might happen (I think this is a non-trivial chunk of the total costs), and so on.
I'm not sure I've seen many cats until I was older (10 years maybe). We lived pretty secluded, only had a dog (and we only saw that dog maybe a couple of times a day or less). We had plenty of poultry though, and we played with chicks (we run after them mostly)
That's rain from evaporation. The device suggested throws salt water into the air - assuming the water evaporates without forming a cloud, all it remains in the air are small crystals of salt.
Hopefully those devices will be installed in such places that the wind will blow the salt water into the sea
Drag is an issue in the Low Earth Orbit (some hundreds of kilometers up). However, Geo Stationary Orbit is at some 36 000 km above ground (more than 20 000 miles)
I want to see a netbook that has a sensitive screen. Multitouch would be nice (all this at less than half the cost of an iPad). And that can be folded "tablet-style" for reading simple things in a cramped environment.
Yes, and if someone doesn't know about Maxwell electro-magnetism, we shouldn't let them use a microwave oven. Or an incandescent light bulb if they don't know the physics of radiation. What about them using electricity from a nuclear plant without them knowing nuclear physics? Or mobile phones without knowing a thing about transistors, logic circuits, liquid crystals, the physics of Lithium batteries?
The Middle Age Church was an organization with a millennia of experience, teaching millions of people, and having even more serious resources behind it.
Even so, it did many things wrong (based on our understanding of right and wrong)
This pin asks for "playing appropriate age-group games", playing based on a schedule cleared with the parent (not hours on end). It might not be what Baden Powell wanted, but it's not so totally bad either.
EvE is not free world PvP - you can stay in high security space and be pretty certain that nobody will attack you (if you stay in 1.0 security space, help is coming in seconds). You might still die, but there's little chance of someone camping you
Hypervelocity missiles run straight at the target, they don't manoeuver (they would be pressed to, at almost a mile a second). Only standard cruise missiles (like the Harpoons) have the option to pop up and dive on target (which they do on a not very steep dive, probably inside the Phalanx's field of fire).
I've read too much Tom Clancy it seems:) On the other hand, 12 launches are three containers, and one simulated fire on a ship might mask them enough for the missiles to reach cruise velocity
If what Wikipedia says is true, Phalanx in auto mode doesn't target missiles that aren't coming for the ship they are installed on. True, this might be programmed, but I think the hit percentage degrades greatly against missiles just flying by.
Diesel-electric subs are also limited in submerged time - but if they use non-air breathing engines they can recharge batteries silently and deep under water.
You can't secure or raid the ocean with diesel subs - but there's nothing better for guarding/raiding traffic through choke points like straits, approaches to ports and so on.
3 Mach cruise missiles have approach velocity at about 1 km/s, so this gives a small window of successful engagement. Also, the Phalanx has only 1500 rounds - I don't know how many missiles it can engage with that. If firing at long range, the hit probability decreases sharply (as the shells fired will scatter). And the attacker will launch the missiles so that they will arrive at the target as close to each other as possible
We're assuming you could put a container ship in close proximity to the aircraft carrier (let's say less than 10 km) - very possible while steaming in crowded waters (Persian Gulf, Panama Canal, even home ports). Maybe even faking a fire on the launching ship, to hide the thermal plume of the launching. This space would be enough to accelerate the missiles to cruise speed then send the final stage at 3 Mach. Total response time would be less than a minute (maybe 30 seconds), with the missiles in range of the gattlings for about one second.
That makes the Phalanx systems each able to intercept one missile (we're assuming missiles on somewhat converging trajectories), and there aren't many Phalanxes. I'd say a 12-missiles attack have a fair chance to burrow one missile in the carrier (the carrier containing a nuclear reactor, aviation fuel for all its planes and plenty of ordnance). Not to mention that we might be talking about an attack from many more missiles.
That's only effective when you need to build some million crowbars, as sending probes anywhere but Low Earth Orbit is very very expensive (and an autonomous smelter would by necessity be huge).

Superior and oversized firepower? What about nuclear bombs?

At much lower prices, and much of those prices go to the companies that actually produce them (ARM is an Intelectual Property company)
I knew the possibilities of wireless communication - I didn't knew it was so (relatively) inexpensive.
Yes, the price also kinda beats the free (included in laptop) and $30 (wireless N router) that the typical home user will pay.

Not to mention the top speed of 200 mph - that's kind of slow for a rocket powered plane (even if the 15 foot long rocket flame is nice looking)

Iran is in the market for this. Should all their vessels be classified as legitimate military targets?
You could use civilian ships (one armed, the rest unarmed) to herd an aircraft carrier towards a waiting submarine
What about a US-owned, US-flagged ship captured by "Nigerian" pirates and steamed to the Persian Gulf?
