Wireless radio systems have been around for about a century now, and Im not aware of anyone ever pulling off a hack of a car radio system or a radio tower through radio transmission.

But you don't have to gain control of a car to do damage. If you can convince a V2V car that the 5 cars immediately ahead just came to a full stop because of a collision, you may be able to trick it into braking hard, causing a collision behind you.

is gonna get anywhere anytime soon... it's nearly worthless until every car on the road has it.. which will take a LONG time.. even getting to something like 90%+ v2v-enabled will take decades.

The benefits start accruing once 10 percent of the vehicles on the road have it. You don't need 90%. You don't even need 30%.

As you rush headlong into a fogged in traffic jam, there is a good chance that at least one vehicle in that jam will this technology and warn your car well ahead of time, so you can slow down (also slowing those behind you). You don't need every car to have this. Similarly, in-road transmitters can warn just enough new cars of trouble ahead to slow an entire stream of traffic.

Sure, not ALL of the capabilities of V2V will be available immediately, but plenty of them will work even with a small percentage of participants.

That being said, development of these systems is far from complete, and shifting them to new frequencies is really a last minute decision. There is no real reason that 5GHZ is ideal for this V2V use, and something much higher up in the spectrum might actually work just as well, if not better.

I thought the same thing when I read the summary. In one breath they are talking about Major crimes, and in the next sentence they lump in iphone theft in that group. Yet if you report an iPhone theft the police won't do a damn thing about it other than give you some paper to fill out. How is that considered a Major Crime?

No I did not overlook Tiananmen, which happened 23 years ago, the same year as the Exxon Valdez disaster, and the US invasion of Panama.

This is not a political issue, it is an economic issue.

My point is that it is simply ridiculous to state that China is just now entering the industrial revolution, when the truth is that China is in the later stages of that revolution, and is quietly entering a social revolution, which is being allowed to happen by the (nominally) communist government.

Contrary to your assertion, I don't expect any violent upheaval in China, nor do I expect progress toward greater freedom and environmental responsibility to slow. China has never known democracy as we understand it in the west. Yet for the average Chinese citizen these are the Good Old Times. They have never had it so good in their long history. They have always lived in a feudal serfdom. It will take perhaps 50 years but they will eventually get to current western standards.

I've maintained for years that China, Mexico, and similar countries going though industrial booms are simply in early stages of industrial revolution. Next we shall see environmental, wage, and health reforms, as these countries realize the need for sustainable management of their labor base.

Actually, they are in the LATE stages of the industrial revolution (as any casual use of Google Earth would reveal). They are entering that state where increased disposable income and increased levels of education cause individual citizens making purchasing choices that drive the economy in a direction of more open-ness, more freedom, and more environmental responsibility. These people enter government and start working toward taking care of the environment.

Progress is slow, but this is exactly the predicted pattern that has been seen all over the world as prosperity and education increase, people start taking better care of their environment, investments, and themselves. Much of the west went thru this in the 60s, 70s, and 80s. You rarely hear of smog alerts in the US any more. They used to be common and long lasting in the past. You actually see clear skylines over most cities these days. Hell, even the Hudson river is recovering.

And yet there are tool for this, no?

Epub is largely just packaged html. You can download free word processors (Atlantis) that will take what ever format you write in directly to Epub. I'm sure there are far more sophisticated tools as well.

And you really don't have to format for each device. It's the device's job to handle standard formats, and most of them do it rather well. Don't kid yourself into thinking they test on a wide variety of devices. Doesn't happen.

The truth is, once the book is through editing it can get to ebook format ready to ship much much quicker than it can be printed. Sometimes from editor to ebook in less than an hour.

I hope you're joking. $15 for any fiction ebook is not a sound business model. I'd buy a good ebook for $5, but not $15.

I can only accept prices like that for certain kinds of non-fiction works where the market is smaller and the production/compilation effort is way higher.

Paying $15 is paying to have it NOW.

If you wait to read it in a couple years, it will be much cheaper. Given the huge amount of written material available since the invention of the printing press, there is no real reason to read any fiction NOW, when reading it later will be just as entertaining.

Waiting a couple years or three e-books start costing closer to the amount of the author's royalties (if he was smart). I'm fine with paying a few bucks to the author. Maybe a few cents to the distribution chain.

Generally 3 to 4 bucks is what I like to pay. But Free is a good price a well.

Sequestering CO2 is not simple, and is currently done mostly by pumping it into used oil fields. It's not certain whether these costs were factored in.

Sequestering it is a lot simpler if you can simply draw if off the top of the CLOSED chamber rather than trying to scrub it out of the stack.
You've got half the battle won already.

What to do with it long term is another problem. But its a problem you would have anyway, so having the CO2 handed to you all
contained is better than where we are today.

Besides coal ash, it appears CO2 is the only by-produce that is not recycled back into the feed-stock.

But, hey, Clean Coal stories have to be knocked down immediately. We can't have it prove even partially successful under any
circumstance. /rollseyes.

Sounds nice, except for the 'combusted in a sealed chamber' bit. How is this going to scale up so they can feed 100 tons/hr through the plant cycle? That is the question.

The key to the technology is the use of tiny metal beads to carry oxygen to the fuel to spur the chemical reaction. For CDCL, the fuel is coal that’s been ground into a powder, and the metal beads are made of iron oxide composites. The coal particles are about 100 micrometers across—about the diameter of a human hair—and the iron beads are larger, about 1.5-2 millimeters across. Chung likened the two different sizes to talcum powder and ice cream sprinkles, though the mix is not nearly so colorful.

The coal and iron oxide are heated to high temperatures, where the materials react with each other. Carbon from the coal binds with the oxygen from the iron oxide and creates carbon dioxide, which rises into a chamber where it is captured.

They ran this for 9 days straight. They only stopped because they were tired. Scaling it up probably is not that much of a problem.
The bigger problem might be obtaining both the fuel and the oxidizers in quantity economically.

Coal powered that finely would be rather dangerous, because it has so much surface area. Exposure to air, any spark could set it
off. Handling it would require special care never to let it flow around or accumulate around the crushers. They might have to
make it in a slurry just for safety, then waste more heat drying it before use.

TFA shows them handling bottles of it, and even then they are wearing masks.

A better word might have been "oxidized" but the good professor probably was trying not to confuse the journalism major
who wrote the story with words too big for their tiny world view.

Lots of CO2 is produced, but it is retained in the chamber and captured, and oxygen and coal are fed in continuously.
They operated it for 9 days straight.

There's no debt until after a sale. A business can refuse to make a cash sale in the first place, and that's legal.

But no business would turn down the sale because you wanted to pay in cash. They would have someone drive it to the bank immediately, but they sure as hell aren't going to turn it down. Oddly enough, businesses that sell $90K cars aren't afraid of money.
