I've always thought what they could do is incorporate a small, propane powered generator, like say around 2.0KW. To get an estimate of the size, honda makes a 2kw one that is about the size of a small suitcase, and weighs around 50lbs.

Maybe make it a modular add-in that you can take in and out of the trunk. The generator is way too small to actively power the car, but it could be ran so that the heat of the motor could be used to warm the cabin (like all gas vehicles do today) when it is extremely cold. The electricity it provided would extend range much, but it would keep you out of resistive heat, which is a real waster.. It would also provide a means of emergency charging for a stranded vehicle

I'd make it propane, because in a quality tank, the stuff lasts virtually forever, and it burns really clean.

United States Begins Flying Stealth Bombers Over South Korea 567

skade88 writes "The New York Times is reporting that the United States has started flying B-2 stealth bomber runs over South Korea as a show of force to North Korea. The bombers flew 6,500 miles to bomb a South Korean island with mock explosives. Earlier this month the U.S. Military ran mock B-52 bombing runs over the same South Korean island. The U.S. military says it shows that it can execute precision bombing runs at will with little notice needed. The U.S. also reaffirmed their commitment to protecting its allies in the region. The North Koreans have been making threats to turn South Korea into a sea of fire. North Korea has also made threats claiming they will nuke the United States' mainland."

They did not say they are using VHF low. They are most likely using VHF HI (>175 MHZ), or UHF frequencies between 400-700MHZ.
These frequencies are in a "sweet spot", traveling much better than > 2GHZ signals and don't get hammered by Sporadic E, Meteor scatter or other weird propagation effects as much as lower frequencies.

Although from TFA, the hop they are doing is 6.2 miles. With decent towers and highly directional antennas on both ends, 2.4ghz could work.

it could make it possible to substantially lighten the weight of automobiles

Possible but steel is actually better than titanium when it comes to the metallurgical property of toughness and fatigue resistance, and its cheap.
Maybe some elements could be titanium-ized, but the body will probably be steel for the near future.

s122604 writes "Automakers aren't too happy about a recent U.S. Federal Communications Commission (FCC) proposal, which uses part of the wireless spectrum assigned to vehicle-to-vehicle technology for Wi-Fi instead.

The FCC announced that it plans to free up 195 MHz of spectrum in the 5 GHz band for unlicensed use in an effort to address the U.S.' spectrum crisis. This could potentially lead to Wi-Fi speeds faster than 1 gigabit per second."

People used to buy cars a lot more frequently, as cars used to wear out a lot more quickly.

Just look at stock photos of traffic from the 50's 60's and 70's, you wont see many cars on the road that are more than a few model years distant from when the photograph was taken.

Now walk through a parking lot, you'll see no shortage of vehicles from the mid to late 90s to early 2000s.

Don't think for a second the car manufactures wouldn't love to go back to the purchasing cycles of yesteryear.

Entirely unrelated

I think you meant "entirely bullshit" cars are more reliable now then they ever have been.
Easy to work on? no.. but cars are more reliable, cleaner, safer, and faster than ever. A car that didn't need some kind of serious engine or transmission work before hitting 100,000 miles used to be the exception, now we get pissed off if we don't get this kind of reliability.

There is a lot of .net interest right now.
I'm getting hit up by recruiters asking me about the tiny bit of C# Asp.net experience that I have (other technologies are much more prevalent on my resume). There's enough interest that I'm thinking about getting the set of magic books that everybody gets and going ahead and getting my certification.

IIS/asp.net/c#/Sql Server isn't the answer to everything, but it allows small to medium sized business to do things that are fairly good, fairly quickly, with programmers that are fairly skilled (and therefore fairly cheap). The purists and self-appointed alpha geeks might howl, but it turns out to work for a lot of folks.

In any case, Hydrogen is probably being used to support the fracking industry.

seriously, the amount of natural gas, used to produce hydrogen for a fleet of these things would be lost in a rounding error in the natural gas industry

Now, what IS being pushed by natural gas industry is LNG powered trucks and trains, and you know what I say: yea for them

Hydraulic fracturing is not a new technology (although horizontal fracturing is), and it does have potential impacts, but those impacts can be mitigated far easier than drilling in deep water.

the side effect is less oil needs to be refined (which is a dirty and energy intensive process), more money stays in this country, and our air is cleaner...

the perfect need not be the enemy of the better.

no, I am NOT a oil industry shill, I think other oil proects like the oil sands pipeline, are absolutely horrible ideas, and I do think the industry needs to be monitored and regulated closely, but natural gas displacing petroleum in transportation, and coal in electricity generation, with alternative energy, like wind and solar, eventually replacing gas in transportation and electricity generation long term is a win for everybody..

A sort? Seriously? I looked at this comment and asked myself if I could write a simple bubble off the top of my head. I muddled my way through it, so I guess I would have "passed". But I do know that there are much better implementations of the sort algorithm. but its been 10 years since i took data structures, and I doubt I could s ruble out a heap sort in the middle of an interview.The thing is I don't write sort implementations every day. Smart people have done this for me, that is the beauty of OO and generics.

Comparing to the 90s is just not apt, not Toyota only sold 1.8 million, are they "dying" too?
Cars are lasting longer than they ever had, and the world economy is still getting over the biggest collapse since the great depression, so such comparisons are not valid

Fine, when you do it wrong, you can have problems

ANY kind of petroleum extraction can, and does, have problems.
Issues with an on-shore hydrofracking operation are far easier than dealing with an issue in deep water
It is unwise economically, and I dare say immoral, to use energy, but demand it come from somewhere else.
My furnace doesn't run on fairy sweat and neither does anyone else's.
We (meaning the "west" in general) would be far better off economically, and even environmentally, if we ran more of our transport on natural gas.
It's also a great compliment to alternative energy sources like wind and solar, given the extreme reliability and variablility of a well desigined combined cycle natural gas electric generation plant.

People are slimy, and the petroleum industry is especially so, so tough, enforcable, and actively enforced regulations are needed, but lets not throw the baby out with the (natural gas heated) bathwater...
