Sure, I do see other brands fail after a year or two, but I've seen more brand new defective Linksys routers than I have Netgear routers that dies of old age.
I've got a WRT54GS, a WRT54GL, and a WRT54Gv8 scattered around my house acting as dumb access points. The oldest is probably seven years old. Once configured, I haven't had to touch any of them. Meanwhile, my pair of Netgear gigabit switches are awful. I've replaced them each twice. Good thing they have a lifetime warranty. I get some issue where they will just start flooding the network with traffic, preventing anything from getting through, and requiring a power cycling. The 24-port Netgear switches at work have the same exact behavior. The only thing I can think of is some sort of STP failure.
The problem with solar power is that there is a lot of uncertainty. In normal climates, you have to deal with cloudy days. In arid climates, you have to deal with sandstorms. In all climates, you still have to worry about nighttime. Molten salt systems with solar power plants are good for minor disruption, but won't last for more than a few hours after the sun goes down. Without some major improvements in energy storage, they will not serve as a replacement for baseline coal and nuclear plants. You're still going to need a worldwide energy grid, or geothermal, hydroelectric, or gas turbine plants for peak and nighttime load.
If you go to a fancy restaurant in the states, that is how they operate. They don't expect to get more than two seatings in during an evening, say one at 6PM and another at 8:30-9PM. You're also paying several hundred dollars for a quality of food and service that makes it worthwhile to tie up a table for so long. If you go for your $5.95 buffet at the Golden Food Trough, it's in their best interest to shuffle you through as quickly as possible.
Put in another way, if you're at a restaurant whose menu has any prices other than whole dollar amounts, eat up, get out, and let the wait[er|ress] have another round of tipping customers.
Microsoft, Apple, Google, and Opera are all publicly traded companies. They all follow the same rules, and they all exist to make money for their shareholders. Microsoft can compete on even footing.
Mozilla is a non-profit organization, and as such, follows different rules and different motives. Think of h.264 like high property taxes. They are a means to create a monetary barrier to entry, to make it too costly for the open source 'riff-raff' to compete.
And just 5 years earlier, you could have gotten the same 15mpg on a car with more than double the horsepower. Lousy government emissions regulations...
Nonsense. Ridiculously parallel applications can soak up tens of thousands of cores, with near linear scalability. For those, you may as well use grid computers running on the idle time of tens of thousands of desktops. Supercomputer applications are run on supercomputers specifically because they have difficulty scaling. They require a large amount of frequent communication between the compute nodes that a detached grid cannot provide, and even commodity 'beowulf' clusters struggle with. You build a supercomputer for that interconnect bandwidth and latency.
Flywheels, compressed air, hydrogen fuel cells (again scale may be an issue) all work just about completely clean.
Flywheels don't work too well on a mobile platform. They're great for stationary installations, and will work for trains which don't do anything quick, but getting a flywheel with enough inertia for any significant energy storage is not going to do well in a car intended to be maneuverable. Compressed air has fairly low energy density, while hydrogen fuel cells require very expensive rare metals, with costly and dirty refinement processes, in their reactors. Both of which can be very dangerous in a crash, and thus have to be very strong and mounted in a secure location in the vehicle.
Hydrocarbon fuels, and diesel more so than gasoline, are just the rare chemical that is both stable, and has a high energy density at standard conditions. Diesel will not burn. Gasoline has to be vaporized first, so it burns slowly. Even high density batteries have the nasty problem of short circuiting. It's going to be hard come up with another energy storage that works so well.
They have proved that bird DNA contains genes that create dinosaur characteristics. The only way this can happen is through the evolutionary process.
You can't prove anything in science, you can only posit a theory that best describes the available data. Another theory that matches the data, but one that can neither be validated nor refuted, and thus cannot be considered 'science', is that God was feeling tired on the day he made 'bird', so he just reused some code he had laying around from an old project. Leave the proofs to the mathematicians.
Given that trying to teach religion in public school is *illegal* for good reason.
What good reason is there to forbid religion class in public school? A good portion of the world (if not better than half) claims to follow one denomination or another. Religion shapes a culture's ethics and customs. It affects how people think and act. Teaching any single religion over others should not be allowed, but not teaching the basic tenants of the world's major religions is a major disservice.
There are two reasons to teach history. You can either learn the history of a people, so you can understand their culture and better deal with them in modern life, or you learn from their successes and failures, rather than having to repeat them yourself. Surely a world religion class would serve those purposes better than the mindless rote memorization of names and dates that they currently teach.
The classes covering religion and alternate belief systems are structured around facts about said groups. Like pillars of faith, holy texts and history about the origins of the religions. It has been decided long ago here that it is essential for our population to at least have a minimum of information about such issues as it makes society a whole lot less ignorant and hateful.
I don't understand why we don't do that over here. Everyone is so feverent about 'no religion in public schools'. The simple fact is that a huge portion of world population claims to follow one denomination or another. Understanding a religion goes a long way to understanding the behaviors and actions of its believers. A good foundation in the world's major religions should be every bit as important as history and geography classes.
"You may have come from a monkey but I certainly didn't."
He's right. We're both descended from a common ape-like ancestor around thirty million years ago. Monkeys are fairly long separated from the great apes we branched from.
Of course the other option would be to have some fun at his expense. God was lazy when he made us 7,000 years ago. That 2% of measured genetic difference means we're basically a shell around a chimpanzee. Some types of surgery can be dangerous, as when they crack the shell open to operate, the chimpanzee may escape, leaving you as a lifeless husk.
This is not a diesel-electric. The vehicle has two independent drives. The electric motor is only geared for up to about 35mph. Above that and it disconnects, and the vehicle relies on the 800cc diesel engine.
Then it's an electric drive with two types of chemical battery. A hybrid vehicle requires that there is more than one type of motor providing motive force. If induction motors are the only thing connected to the wheels, it is not a hybrid. Just because 'hybrid' is the latest buzzword doesn't mean it is something to aspire to, and we need to rename everything we can to be hybrids. Well... except for those cases where the hybrid volkswagen is pure awesome.
There is no such thing as a 'series hybrid'. Modern trains are diesel with an electric transmission. A hybrid necessitates that there is more than one type of motor directly providing motive force.
It's the implication of what 99mph means. It is not artificially governed, that's simply all the more power the car has. It's going to take you 20+ seconds to get up to highway speeds. With short on-ramps that go uphill, that poor of acceleration is downright dangerous. I got a low end Ford Focus loner while my car was in the shop once, and even with it floored I only managed to get to 45mph before I hit the end of the on ramp. On a crowded highway where the flow is going 65mph, you can get in some real trouble.
Is LI the only way to feasibly go on these? You cannot refurbish LI, so it would seem you're creating another non-green problem by using cars like this.
I'm surprised sodium-sulfur batteries haven't gotten more attention. High power density, similar energy density to L-I, very high cycle count. The internals are corrosive, but no worse than existing lead acid cells. The only significant problem I see is that the batteries must be maintained at temperature, so they will have a fairly high self-discharge rate if you leave your car sit for long periods.
I could see it being kind of scary to drive on the highway unless its got some serious aerodynamic down force.
If it had serious aerodynamic down force, they would lose a lot of fuel economy. There's a good reason most sports cars have surprisingly high coefficients of drag.
Diesel-electric drives are not hybrids any way you want to look at it. There is only one type of motor directly attached to the propulsion unit. There is only one type of motor generating power. It's an electric drive with a generator, or a diesel drive with a fancy transmission, but not a hybrid.
Either way, I doubt this car has such a setup. The article mentioned a 7-speed gearbox. The only reason you would do that is if you were connecting the engine directly to the drive train and wanted to ensure efficient operation. If it were straight electric, the engine could be run at optimum conditions at all times, and the electric motor would have at most a 2-speed gearbox.

I got the conversion backwards. It's actually 27hp.
Yeah. This was a POS 3-speed automatic, down from a 200hp 5-speed manual. I was not happy with that loner car.
No, it cant. The electric motor is only rated for 15hp, and its geared such that it red-lines and clutches at 35mph.
Except that the car weighs far more than that, and with car, driver, and fuel, you're up over 2000lbs.
