It would basically put large swathes of the printer manufacturers, printers, the book publishers, the ink makers, paper mills etc etc out of business. It'd have quite an effect on forestry as well.
BTW, anyone know of anything similar to the Gutenberg project but storing the scanned images of the pages?
"Thanks to the precision and accuracy of modern electronic hardware, this calculation can be accurate to within 20 meters or less."
The Ordnance Survey mapped the British Isles to an accuracy of less than 1 metre, top to bottom in 1935. Modern electronic hardware doesn't sound quite so accurate or precise when put into that kind of context.
"To charge a car in 60 seconds is going to require one heck of a conductor!"
True but power (Watts) = voltage * current. You can supply power either through big voltages, big currents or both. Big voltages need good insulators, big currents need good conductors. Our trains already use those levels of power, the engineering and experience to handle it is decades old.
A couple of other things to consider. The infrastructure rather than the car becomes the limiting factor in the speed of recharging, but the basic infrastructure already exists.
How long do you typically stop on an N hundred mile journey? You're talking 4 hours solid driving at 70mph on a 300mpc battery. I personally can't go more than 2 hours without a rest. A cup of tea or coffee takes 20, 30mins.
There would be no particular reason for the electrical equivalent of a gas station, you'd plug the car directly into the parking space when you stop, electricity is already distributed pretty much everywhere, it makes much more sense for car parks to install charging stations.
You could also charge the car over night at home from your domestic supply.
"but it's not the only game in the book, and every year the likelihood of a high-tech terrorist attack will increase."
I disagree, high tech is by nature inflexible and brittle. It requires a certain infrastructure to work. Break or interfere with the infrastructure and the high tech stops working, which is why it isn't going to be a significant terrorist problem.
Batteries exist today, are rechargable from any domestic power source. Last for several thousand full discharge cycles with negligible degradation. Have a high enough energy density (higher than compressed hydrogen gas) to power a car for 300 miles per charge and they can be recharged in 60 seconds.
"How many charge cycles before the nasty insides of those batteries end up inside a landfill"
The insides are lithium based rather than heavy metal based for a start and if you had bothered to follow the link and read the article before bothering to reply you would have known before bothering to reply that there is a one percent degradation per one thousand full cycle discharges. Battery electric cars have been capable of 300+ miles per charge for several years now. We are talking hundreds of thousands of miles, more probably millions of miles of life out of the battery.
"Lithium is considered a pollutant, as is sulfur"
Hydrogen is highly explosive and oxygen makes things burn very quickly, the combination of the two must be horribly dangerous, I wouldn't like to have any dihydrogen monoxide anywhere near me, would you... Do you have any idea what you're talking about?
Just in a global competitiveness sort of way. The US has shipped most of it's manufacturing abroad, is busy shipping it's IT sector abroad. Allowing the patenting of business processes is I admit rather a bizarre way of pushing the rest of business out of the country but hey, most of the world is poor and could do with the trade.
So it only makes sense that everyone outside the US should help Amazon lock down the US markets by buying stuff from them. They're also pretty cheap for books.
Installing firefox is simple. The only thing you're changing is your browser. Installing and using Linux requires a significantly larger investment in time and effort (Call it work, as in Work = Force * displacement * cos(Ø)) because everything is changing; document formats, applications, menus.
In order to justify the work invested in switching to Linux there must be a benefit larger than that investment. The fact that there is a trend towards linux at all actually proves that the benefit to the end user is real, the fact that it's relatively slow says that the work required to do it is significant.
Things like KDE, Open Office reduce the distance required to travel but the rate of people converting to linux is always going to be relatively low until a Linux CD can be popped into a Windows machine and "upgraded" automatically exactly as if going from Fedora Core 3 -> Fedora Core 4. Preinstallation would also help.
We'll see it tested in airports, university campuses, small towns at first in various incompatible guises over the next couple of decades. It'll end up everywhere.
Any electricity which can be used to generate hydrogen can now be stored in batteries with a higher energy density than compressed hydrogen gas and yes, with negligible degradation. Go check out the state of the art in battery technology.
The fact that they get away with it is a shame. It's even worse when they have an influence on government policy. Ugh.
Lots of people can't think of a good reason to do science, maths and statistics at school. Well, a bloody good reason is so you can prevent the wool being pulled over your eyes.
Get rid of the unnecessary crap installed on your system to help improve your boot times. Have you seen the junk FC4 installs and starts at boot by default?
Totalitarian regimes can only survive as long as there is no real opposition. That means getting rid of the middle classes who have money, education and influence. Russia and China did it, as did Cambodia. We can see the process in Africa with Mugabe at the moment.
Today China is busy building back up it's middle class. The inevitable result of this is going to be increasing demand by the moneyed class to have a say in how they are governed, that will ultimately mean liberalisation and a form of democracy.
"Seriously, do you really believe terrorists won't be using strong encryption, knowing their data packets are probably being sniffed by the feds."
Actually. No I don't believe the terrorists will bother using strong encryption. They'll have their instructions memorized, with information passed in person. You don't need a computer to blow up a train or a plane.
All this high tech stuff is futile, the terrorists aren't using it. The fact that the FBI are chasing it says to me that they don't understand the nature of the threat or they're after something else.
In a market, people generally try to choose the best product at the lowest price. That means you have to know what the best product is as well as how much it's worth. Information is power.
Well, if your product is chalk, then people aren't going to be willing to shell out £2.50 for a box of 30 chalk pills are they? So they sell you Settlers Tums instead of selling you chalk. Think of branding as economic disinformation.
Exactly the same techniques are used in business management for exactly the same reason. To confuse the market and get people to shell out more money for the same commodity product (management). Economic disinformation.
Not per day. The bigger stations handle 20,000 -> 30,000 people per hour during rush hour.
So they'll have about 1/10th of a second to scan each person at peak times.
Lets say it takes 5 seconds to scan someone and identify that they're harmless, which is the key bit. That's only 720 people per hour, they'd need 42 scanners + personnel to cope.
Basically they're dreaming. It's not going to happen and if it does, it's not going to work.
Seriously, the logistics just don't stack up. At rush hour there are tens of thousands of people per hour going through many of the stations (20,000 -> 30,000). There isn't a snowballs chance in hell of any meaningful level of scanning of people at those types of rates.
Therefore we either slow the rates down, and turn people away from the tube (*not* going to happen), or (and this is what'll really happen) the scanners will be just for show and the money spent on them should be considered as public relations.
Don't think you're going to be able to generate your own hydrogen, the govenment gets plenty of tax revenue from fuel companies and the fuel companies are going to want you to continue to spend money with them, so home production of hydrogen is almost certainly going to be illegal, justified on safety grounds of course.
Um, your ignorance is showing. You don't need 350bhp in an electric vehicle, they produce peak torque at 0rpm. The 350bhp your BMW produces is peak power, probably at around 5000-6000rpm, you run your car at 6000 rpm all day? Do you know the difference between power and torque?
ACP have an electric sportscar called the Tzero which does 0-60 in 3.6 seconds and has a range of 300 miles per charge (Don't take my word for it, look it up). The batteries cost a few thousand dollars (Sub $10k), not $20 million. Toshiba li-ions (the ones mentioned by the parent) will happily do several thousand full discharge cycles with negligible degradation.
"Did they already figure out how to make Li-Ion batteries last longer than a few hundred recharge cycles ?"
Yes. The degradation is negligible.
"Sorry, it's one thing to recharge a battery for a small portable electronic device in a few minutes..."
Correct, but that is an infrastructure problem, not a battery one. Producing and distributing hydrogen is just as big an infrastructure problem. The difference being that the basic power distribution network already exists.

You'd better phone the RAF before someone gets themselves killed then.

Have a high enough energy density (higher than compressed hydrogen gas) to power a car for 300 miles per charge and they can be recharged in 60 seconds.
Hydrogen is a red herring.
Read the article. 60 seconds to 80% charge. The limitation is the infrastructure, not the battery.

In terms of the mathematics of getting from A->B, it's the optimum solution. Highest performance for lowest cost, lowest energy consumption.

You go to a chemical supplier to buy your fuel.
