Some guy engineers his own 9/11 experiments

joedirt says...

For reference...

NIST report and press conference:
Sunder said that his team investigated these hypothetical causes [thermite] and ruled them out. "We asked ourselves what is the minimum amount of charge we could use to bring the building down," he said. "And we found that even the smallest charge would release an extremely loud sound heard half a mile away." There were no reports of such a sound; numerous observers and video recordings found the collapse to be relatively quiet.

FEMA:
The eutectic temperature for this mixture strongly suggests that the temperatures in this region of the steel beam approached 1,000 degrees C (1,800 degrees F), which is substantially lower than would be expected for melting this steel...

FEMA:
Temperatures in this region of the steel were likely to be in the range of 700 to 800 degrees C (1290 - 1470 degrees F).

NIST:
In no instance did NIST report that steel in the WTC towers melted due to the fires. The melting point of steel is about 1,500 degrees Celsius (2,800 degrees Fahrenheit). Normal building fires and hydrocarbon (e.g., jet fuel) fires generate temperatures up to about 1,100 degrees Celsius (2,000 degrees Fahrenheit). NIST reported maximum upper layer air temperatures of about 1,000 degrees Celsius (1,800 degrees Fahrenheit) in the WTC towers (for example, see NCSTAR 1, Figure 6-36).
However, when bare steel reaches temperatures of 1,000 degrees Celsius, it softens and its strength reduces to roughly 10 percent [***NOTE: no reference] of its room temperature value. Steel that is unprotected (e.g., if the fireproofing is dislodged) can reach the air temperature within the time period that the fires burned within the towers. Thus, yielding and buckling of the steel members (floor trusses, beams, and both core and exterior columns) with missing fireproofing were expected under the fire intensity and duration determined by NIST for the WTC towers.

What is concerning is that thermite was rule out because of the noise, and that 1000 lbs would be needed.

Also, no one has explained the UL testing on the steel for 6 hrs at 1000C?

Finally, what is troubling is that softening girders causeing collapse, fine, steel is weakened at 1400degF, but the core wouldn't fall. Certainly wouldn't break apart.

The Dresden Dolls - "Coin Operated Boy"

eric3579 says...

coin operated boy
sitting on the shelf he is just a toy
but i turn him on and he comes to life
automatic joy
that is why i want a coin operated boy

made of plastic and elastic
he is rugged and long-lasting
who could ever ever ask for more
love without complications galore

coin operated boy
all the other real ones that i destroy
cannot hold a candle to my new boy and i'll
never let him go and i'll never be alone
not with my coin operated boy......

this bridge was written to make you feel smittener
with my sad picture of girl getting bitterer
can you extract me from my plastic fantasy
i didnt think so but im still convinceable
will you persist even after i kiss you
goodbye for the last time
will you keep on trying to prove it?
i'm dying to lose it...
i want it
i want you
i want a coin operated boy.

and if i had a star to wish on
for my life i cant imagine
any flesh and blood could be his match
i can even take him in the bath

coin operated boy
he may not be real experienced with girls
but i know he feels like a boy should feel
isnt that the point that is why i want a
coin operated boy
with his pretty coin operated voice
saying that he loves me that hes thinking of me
straight and to the point
that is why i want
a coin operated boy.

CBC thoroughly deconstructs homeopathy

spoco2 says...

Ha! Brilliant idiot: "Homoeopathic remedies take longer than the 'quick fix' medicines but there's nothing bad in there for them"... you are actually spot on Ms.

They take longer because they do nothing, it's just your own defenses doing their job (which in a lot of cases IS actually a good thing to let happen, this over reliance on Antibiotics is a bad thing) . And there IS nothing bad in there because it's just sugar or lactose... well done...


Hey, wait! They're not shaking it the right way... oh man, they're going to create terrible homoeopathic medicine... don't they know anything? It has to be "vigorously shaken by ten hard strikes against an elastic body"... amateurs!


And it's a standard bullshit speak to stare bald faced at facts that say your product contains nothing of benefit at all and just wave it away with "well, science can't measure what's _really_ in these 'medicines'"

I didn't know that people were taking this crap over vaccines... that's horrible.

F*ck I hate homoeopathy, hate that SO MANY people are suckered in by it because the mainstream media (at least here in Australia) don't seem to say anything against it, and such large 'professional' companies sell it in chemists that it just gets lumped in with natural remedies. I'm all for natural remedies when they've been shown to actually do good, and am also all for letting the body fight off illnesses when it can compared to attacking it with drugs. But MAN, you just KNOW that 90% of the people who make this shit know that it's shit.


ARRRGH! Seething at the STUPID mother who says 'if people did a little more research'... FUCK! She has obviously done NONE... it really isn't hard AT ALL to find out what a steaming pile of crap homoeopathy is, and it's not like it's complicated to understand. THERE IS NOTHING IN THE 'MEDICINE' AT ALL

Scientific Experiment: Slapping the Posterior in Slow Motion

honkeytonk73 says...

BAD SCIENCE. They need a naked butt control group to make sure the spandex shorts aren't inadvertently affecting the elasticity of the buttock upon impact. I think this experiment should be redone, and I am willing to sacrifice my valuable research time TO DO IT RIGHT!

LOL you can go from mouth to vag without skipping a beat.

It's a good think you can't see what I'm thinking while watching this video. That kiss of the spider woman pose makes me have naughty thoughts.



>> ^Lann:

^ That's what jimnms was getting at without actually having to say anything...slick.

Solar Highways!!!

malakai says...

Not only does it have to follow contours of the land, but these panels would have to be able to deal with subsidence of the layers of earth under the foundation due to constant rolling point loads from trucks (since cars weigh nothing compared to a fully loaded truck). Asphalt/bitumen can elastically deform and still be a via road surface (i'm sure everyone's noticed 'channels' in the road). Couple that with the need to remove surface run-off water when it rains. True you could make the top road surface bumpy, but once those bumps are worn down you cant re-surface without replacing a whole panel.

On top of that, what happens if the micro-processors suddenly crap out, or some of the LEDs blow. In the first case, any road markings would suddenly disappear, or conversely the road would suddenly light up blinding drivers. In the second case, you'd either have to replace a full panel, or have "acceptable defects" where a certain number of LEDS can blow and the panel won't be compromised.

If they manage to get this to work, kudos to them, but i just can't see it happening with what they've been showing. Would seem to be easier to harness the thermal energy of roads rather than solar energy acting on the roads.

TED: The Gulf Oil Spill's Unseen Culprits and Victims

GeeSussFreeK says...

I am all for ending all subsidy of energy, oil, coal or otherwise! I would LOVE to see technology finally take government out of energy production. I would love for every house in America to be its own power generator. Could you imagine stopping off at someones house to "fill'er up"! That would be so cool to me! We still might want to keep "the grid" around, but it would fulfill a totally different function. I am hopeful that a combination of solar power + hydrogen fuel cells will give us this ability. Solar seems like such a cash crop of energy, and fuel cells give you the mobility aspect. Time will tell if this comes to be, but it seems pretty promising now with solar cells reaching 50% effectiveness!

I know of studies that talk about feedback loops for weather, and while intellectually intriguing ( I love all things dealing with Apocalypse!), it seems to be without any real historical evidence. Most mass extinction due to weather change that we have any real evidence of are due to catastrophic events such as massive volcanic activity or comets and meteors. While I don't doubt that human CO2 levels could do something that equates to those, I question if we produce the amounts necessary at this point in time. I have tried with little success to find ice and CO2 levels of the Mesozoic era. However, I have read somethings to the contrary of the capacity of the ocean to stabilize the temperature better than ice. Liquid water has a very high specific heat, by increasing the volume of water, you could have an even more effective heat dissipation system than that of reflective ice. I lack any real education into which one is more true. Interestingly enough, CO2 levels were most likely 10% higher than today during the Cretaceous period. There might be slightly more elasticity in the climate than most people have come to understand.

I disagree that the government needs to "create a market for something". If it is one thing governments are very poor at doing is creating markets for things. People do this better and faster than government think tanks. I do however support new understandings in pollution in how it interacts with property rights. If you clog my air with filth, there has to be some legal ramification to that. It is due time to assess how property is defined in terms of air, water, and the like, I welcome that conversation.

Fully Functional Lego Sniper Rifle

heathen says...

>> ^nanrod:

Duh! I was kinda thinking about the reaction when this shows up fully assembled on an X-ray>> ^heathen:
>> ^nanrod:
OK. Who wants to be first to try and board a plane with this in their carry on?

Would be pretty easy, disassembled, just some Lego bricks and elastic bands.



In that case, no chance. These days a picture of a gun on your T-shirt is enough to stop you boarding a flight.
