I'm smart. Your a dweeb you dweeb.

It does not appear that we are mature enough to discuss real scientific matters.

I personally dislike IFLS because it takes a personal point-of-view on lots of topics and personal beliefs rather than solid science. It used to never leave sources for its articles, but has gotten better at that recently. Either way, I can't stand by the site.... One of the many reasons being that I can't stand the name of the site itself. I don't see how that shows any professionalism...

I'm mature.

What kind of animals/insects/etc. are your favorite?

I like sea otters and sharks.

As for bugs....

Mantises and katydids're pretty cool.



Mmmm....I don't wanna sound dumb so I'll keep my actual comments to myself, but if anyone likes quantum mechanics/superconductors, Essen, Germany has the world's longest superconductor and it's been workin' beautifully: http://eandt.theiet.org/news/2014/oct/a ... review.cfm

During a briefing in Essen the project partners praised the trial, saying the 15cm diameter cable not only allows transmission of as much electricity as the previously used ten-times thicker copper cable but also enables simplification of the city grid scheme, reducing the number of transformer stations required by 40 per cent.

“We plan to extend the test until 2016, to see that the system performs well in various weather conditions. If the results are good, we may consider a more widespread implementation of superconductor technology as part of our electricity network.”

“We had to switch off the cable only once for a very short period of time during the first 180 days of operation,” said Oliver Sauerbach, RWE’s head of grid planning in the Ruhr region. “It was during the power outages caused by the Ela storm, which disabled the cooling system of the superconductor. However, the data later showed we could have left it on as the temperature wasn’t raising that fast.”

“The liquid nitrogen flows through the 1km-long cable from the cooling station through the outer channel and returns back through the inner path,” Sauerbach explained. “That’s 2km to complete the circle there and back to the cooling station, after which the liquid nitrogen returns three to five Kelvin warmer than when it left. About 2.5 cubic metres of liquid hydrogen are circulating inside the cable at any given time.”

Bednorz, who together with his colleague Müller received the Nobel Prize for Physics for his work, was present at the AmpaCity 180-day review in Essen, expressing optimism that superconductors could revolutionise power transmission in the not-so-distant future, minimising transmission losses and contributing to cutting carbon emissions.

He said that integrating the superconducting technology with an efficient cooling system was likely the greatest lesson to be learned from the Essen trial.

According to Frank Schmidt, head of Nexans’ Superconductor Division, the price of the superconductive cable was only twice as high as that of a similarly powerful copper cable. The whole system, Nexans said, can perform more efficiently than a conventional one, reducing operational cost by €10m over a projected 40-year lifetime.

“With a copper cable system with all its transformer stations, twice as much energy is lost than we need to power the cooling system of the superconductive cable,” Schmidt said.

“The fact that the superconductive cable is considerably thinner than a copper-based one with the same performance makes the installation much easier as you don’t need to dig such a big trench. That’s especially valuable in an urban environment as it minimises disruption plus all the land that can be freed for other purposes when we get rid of the transformer stations.”

The technology is basically ready for the market,” Schmidt said. “In the future, we would like to install longer cables, up to 3km long, and continue with tests in the city environment, which we believe could benefit the most from the technology."

Over the first 180 days of its operation, the AmpaCity cable delivered about 20 million kilowatt-hours of energy to customers in Essen, powering approximately 10,000 households.

did i overquote the article

That's really awesome. I'm sure a lot of "green" folks out there are looking forward to that a lot! I'm just curious on what major side effects could come out of this considering what it's being powered by...

[GoldenPower89]

Speaking of being "green", I found this sticker inside my fridge. Do these gases have a negative effect on the food I eat as well?

[JCTC]

Yes. You will die.

I think the name itself implies their goal isn't to show any professionalism. It seems like they just wanna educate the masses, even if their articles are a bit "skewered" with biased thoughts.

I'm smart. Your a dweeb you dweeb.

*You're

Mmmm....I don't wanna sound dumb

Too late. Say whatever you want no matter how wrong people THINK it is. Science is just 99% educated guesses anyways, mostly everything is just theories and everything always changes.

iz hype.

I'm pretty sure this won't last long. For SOME reason, some of the most useful and beneficial things (like this) have abruptly stopped out of nowhere, and almost never worked on again. I actually remember watvhing a documentary on a few fellows who claimed to have discovered a source of unlimited energy, and even tried to sell it, but they either died or disappeared shortly after.

Still, hopin' for the best.

... How old is that fridge...?

No, if I remember my facts correctly, then your food'll be fine (for the most part). If you paid attention in school, they explained alla that. Old models like that (and I think some modern ones) use chemicals that damage the Ozone layer. At worst it might affect your plants and probably small pets, I think (iunno I slept through school).

But I HIGHLY suggest you invest in a new fridge. Your fridge might as well be powered via hair spray. Plus that thing'll probably break down within no time at all if it's as old as I'm imagining.

[K73SK]

I'd probably just google whether CFC11 or CFC12 is really bad. I have very little knowledge on that side of the table, so I can't tell ya... But like Red, I doubt it would because they'd probably consider NOT using it for a fridge of all things.

[JCTC]

why not?
