Re:Tornado Alley Could Be the New Middle East
T. Boone Pickens demonstrated someone getting in too far over their head too fast in this market. I really wish he would explain to everyone what went wrong with his plans. Who knows? The cement for the bases could get too expensive?
He tried to change Texas law so that the water supply corporation he owned in the Texas panhandle would be able to use eminent domain to take land on a corridor to Dallas/Fort Worth, so as to convey the wind power. Oh, and he could use the same corridor to convey water from the panhandle to DFW as well.
In all those wind power ads and interviews you saw, he never did mention the fact that he owned significant water rights in the Texas panhandle, and just needed a route to pipe that water to major cities to sell it. Do you recall that part?
When Texas balked about letting him pump the panhandle dry and flood (literally) the DFW market with his water, he stopped his ruse of caring about the environment.

Where does free software come from? Or music put under a Creative Commons license? Well, where that comes from, so can other things come from.
> "If people only do the work they want to do, who will do the dirty jobs?"
Seriously, what percentage of jobs are there that are "dirty"? 1%?
People who think they need to be done. Do you ever vacuum your house or take out the trash or clean up after dinner? If no one wants to do them, then we can either re-engineer the work to be fun, we can re-engineer it to not be needed, or we can re-engineer it to be automated.
If, for example, no one liked working on cars, we could probably re-engineer them to require less maintanence effort, or design them for automated maintenance by making them more modular. Electric cars may require much less maintenance, for example.
> "Who will collect the trash?"
Well, what about home recycling systems based on nanotech disassembly? Or what about robotic garbage trucks which pick up standard containers (see the DARPA Grand Challenge to see how trucks can drive themselves)?
Besides, why not just create a public logistics system for moving packages, where the same trucks or robotic vehicles or subway tubes that bring stuff to the homes take unwanted stuff away?
> "Who will work in the sewer plants?"
Well, John Todd developed biological sewage treatment plants that are pleasant greenhouses. Lots of people like working in nature. Just because you can force desperate people to work in today's chemical monstrosities of water treatment systems does not mean their are not alternatives.

Most US crop land is used for animal production and people would be healthier with a mostly vegetarian diet. That would reduce the amount of people working in agriculture from about 1% to maybe 0.1% of the workforce. Lots of people like working with growing plants, especially with machines and robots to do the hard work. As for actually slaughtering the animals, people are learning how to grow meat in vats, so that won't be needed.

Re:NIST's SLIM program would be a better use
The only significant value of resources in space is to use them in space (and maybe to send back information through their use). To use resources in space, we need to better understand manufacturing. Hydrocarbons being imported back to Earth? Solar panels are a lot easier, as are windmills and lots of other things. Even a large amount of energy use can have a minimal impact on the Earth with the right renewables.

Re:DieselsOne reason is that the Hybrids spank TD's on city gas mileage. Sure TD's get 40-45mpg, but that is on the highway. In city driving the hybrid's usually beat the TD's. Here is an article comparing the Jetta TDI & The Prius:

Here's some data...
I agree that the data and code should be made public. Fortunately, NASA has been doing this for some time, as have many other researchers. Gavin Schmidt at NASA has put together a list of links to global warming data and code that is available online.
If you are interested in the scientific context of this story and the emails, I would recommend reading Gavin's posts on context at Real Climate as well.
There have also been interviews with Gerald North who led the NAS investigation into the hockey stick controversy a few years ago, and Peter Kelemen, prof at Columbia, explaining why this hack will not affect the science. Basically, global warming theory is supported by many lines of evidence from many different sources, and does not depend on the credibility of any one source. Furthermore, there is nothing in these emails or data that actually disproves any of the published research.
If this is the best skeptics can do, I think they're in for a rough time. The skeptical argument has little scientific support, so they resort to a silly PR stunt like this hoping to get a draw in the public debate. It has been great to see prominent deniers like Inhofe in the senate going way out on a limb, claiming this proves global warming is a hoax and so forth. There will hopefully be full investigations, at which point they'll probably end up looking pretty foolish when the science is vindicated.

Re:Diesel fuel fire
WTC 7 was NOT a hardened building. It was constructed in the early 80s as a run of the mill office building. The only thing unique about it was the unusual arrangement of the load-bearing members. This was needed because the thing was constructed on top of a massive utility vault. The Emergency Command Center was shoehorned into the building and not everyone thought the location made any sense for obvious reasons. (It was located there AFTER the '93 bombing)
As for the collapse, it looks "controlled" because buildings don't usually fall down for any reason other than controlled demolition. That's the only point of reference most people have. That aside, physics ensure that buildings tend to fall straight down, or twist a little and then fall straight down.
But if you want more in-depth detail about how stresses were distributed and how the building was comprimised, then check out this link or or this one.

Wind is worthless from a cost pov anyways...
Oh really? Payback period: The Energy Information Administration lists average U.S. residential electricity prices at 11.23 cents per kwh, as of February 2009. A turbine that puts out 2000 kwh a year saves $224.60 annually at that price, making the payback period just under 20 years on a $4500 panel. (The government rebate would lower the payback period to about 14 years.)" 3.5.4 Payback
"The detailed analysis done regarding the payback shows that with good wind resource at the installed site, the payback for a 15kW wind turbine will normally be about 10 years. Further with the usage of additional storage facilities like battery would increase an additional payback period of 13 years."Meanwhile the nuclear power industry is Hooked on Subsides. "How do France (and India, China and Russia) build cost-effective nuclear power plants? They don't. Governmental officials in those countries, not private investors, decide what is built. Nuclear power appeals to state planners, not market actors."

paying for roads
Right, the rest is covered by use taxes on commercial trucks and shipping services. Just like they would be under a free market. Individuals would be able to use the road for little or no cost, perhaps a hundred dollar a year pass (which they would save in gas).
Wrong, fuel tax, taxes on commercial trucks, and shipping services does not fully cover the costs of roads. Here's a page from the Oregon state government: Road User Fee Task Force. In it they propose using a mileage fee to cover the cost of the roads. From Popular Mechanics, Should the US Tax Mileage or Fuel?: Guest Analysis. Heck some of the so called stimulus money is going to roads. A few miles from me a road is being repaired and there are signs all along it saying the work is being supported by the American Recovery and Reinvestment Act of 2009, notice how core investments are being made in roads

Re:space junk
It just not so bad that theres any need for something as expensive as the shuttle yet. No immediate crisis for government action, and certainly no profitability for the private sector.
No crisis? So there was no problem when China used a "ballistic missile to destroy one of its defunct weather satellites"? And the experts are all wrong? It was just a mirage when an American commercial satellite and a Russian retired satellite collided? " Close calls in orbit happen all the time--scientists estimate that launch vehicles and other objects come within striking distance of one other over 1000 times a day." That article says how the collision of the two satellites created a cloud of debris that spread around the world in a few hours. Further it says "The junk was in the orbital path of the Hubble Space Telescope and just 250 miles higher than the orbit of the International Space Station."
there really isn't that much salvage value in most of the stuff floating around
There isn't? The Pop Mechanics article above says that best possible space-junk solution: salvage isn't allowed by the 1967 Outer Space Treaty. It prevents businesses from salvaging defunct crafts. I don't know if without the treaty it would be profitable now or not, but when one or more critical crafts collides with space junk people will think differently. Personally I think those who put the junk in space should be responsible for it, but because the US put a lot of it there I doubt that will happen. Nor do I think Russia or China will agree.

Re:Vaporware
Citation please. Common sense tells me you are probably misrepresenting this. Most likely the battery housings are the same and the electrolyte and plates have been replaced, making it a "remanufactured" original battery at best.
Thomas Edison invented the alkaline battery. My Baker still has some original alkaline batteries. These have lead plates and use acid; we wash them out and refill them regularly and I'll use them indefinitely. But even Edison realized the future of the automobile was elsewhere. Legend has it that back in 1896, at a dinner party, he passed a note to his friend Henry Ford. Essentially it said, "The electric car is dead."

Every last detail. I'm waiting. While you're at it, go ahead and explain how your "personal experience" with large, actively-cooled 50% DoD NiMH packs explains why so many people are deluding themselves into thinking that they never had their Prius pack replaced.
After all, your experience with high-DoD, non-cooled 18650 cobalt cells and similarly managed lead-acid batteries has oh so much bearing on actively cooled nickel-iron, LiP, manganese spinel, or NiMH packs with low DoD.
Tell we where I can go buy one of these cars with the 10 year battery warranty?
Obviously the Volt is not on sale yet, but you can get a Prius today with an 8 year warranty and a near-zero battery failure rate.

Re:Not necessarily so funny

Re:And they will hit the shelves in...
The mercury thing is a highly over-rated problem.

CFLs are dimmer than "equivalent" incandescentsin 2007, Popular Mechanics compared a variety of CFLs. The headline finding was that their staffers subjectively preferred the light from any of the CFLs they tested to that of the incandescent bulb they used as a comparison point. This would be more compelling if they'd included a variety of incandescents rather than just one - perhaps that Sylvania bulb was particularly poorly suited for their tests. But set that aside and just look at the numbers they measured. Every CFL they tested put out less measured light than the "comparable" incandescent. They were all "rated" as being 13% brighter (1200 versus 1075 lumens) but actually measured output was 5-15% dimmer (eg, the Westinghouse Natural Light was 840 lux versus 975 lux for the Sylvania). A difference between "13% brighter" (as advertised) and 5-15% dimmer (as delivered) explains quite a lot of the disappointment surrounding CFLs.
It also might explain their findings - perhaps being 10% dimmer made a significant difference in the subjective light quality. They probably should have compared with a 90 watt incandescent to make the comparison more apple-to-apples.

stop with the "off-grid" bullshit.
BS! People have been building off the grid since the beginning of civilization. Only those who do it today have electricity. Offgridders use various sources of alternative energy including geothermal, solar, wind, and microhydro along with others.
producing your own needs for electricity is great
but its a VERY SMALL amount of the world's total energy consumption.Today off grid applications are small but it can easily be expanded. Solar, wind, and other systems can quickly be added. Solar panels can be placed of roofs for instance. Farmers can erect, or have erected, wind gennies on towers. They don't take up much space and they'll create a new source of income for farmers.
But the first thing offgridders do though is to reduce energy use, conserve electricity. Instead of using 75 watt incandescent lights, they'll use 15 watt CFLs or LEDs under 10 watts. For hot water, tankless instant on water heaters are more efficient. Solar hot water heater systems can bee used themselves, or can preheat water for instant on heaters. Passive solar designs can reduce any need for heating and cooling of indoor space, and with insulation with high R values heating and cooling can be eliminated. But even if heating is needed or wanted geothermal heating can be used. And by reversing the system when hot it can cool space as well.
There are many things that can be done to reduce energy consumed.

Re:I have tried it - use the meter correctly
Contrary to what the poster above says, CFLs generally emit a broad spectrum of light, and in most cases it's actually broader than incandescents.

A comparison is available here: http://www.popularmechanics.com/home_journal/how_to/4215199.html?nav=hpPrint&do=print
In any event, a CFL certainly DOES NOT use more energy, so if you think they do based on some past experience, then your test methodology was flawed. Plug your lamp into a wattmeter and try again. If your generator was using more fuel, then something else was on.
