Can You See the Fire? -- Extreme Science #2

Real Time - Dr. Michael Mann on Climate Change

newtboy says...

You certainly have a choice in how you use the electricity.

I think YOU missed the point, if you can only sell your power for 8 c perkwh, and pay 36c per kwh, and you sell ALL the power you make, then buy it back later, YOU are subsidizing the power company, who makes 28c on every kwh you sell them. No one is subsidizing that 8c they pay(I would hope, 350% profit is already insane) so what "high feed in tariff" are you talking about?

The power grid is fairly smart, and takes into account the amount being produced by ALL sources, and shuts/ramps down those not needed. For you to be sending power when it's not required would require more PV generation than the entire grid uses, because ANY other generation could be put on hold until night. The certainly DO do this on a 'few hundred times per second' basis, at least here in the US. Solar generation may jump up and down on individual systems, but the total amount fed to the grid by all solar systems in an area is fairly stable, and doesn't jump radically from a cloud...come on.
Here, peak power is at peak temperature time, mid-late afternoon, when businesses turn up the AC and people get home, exactly when PV makes the most power, I can't speak for AU.
The point being that the grid CAN and DOES adjust rapidly to account for all generation methods, and it does already shift production because some of the need is supplied by PV.

Not so, the return on energy invested is at least double the return on coal in the long term...for the consumer, that's why you save money VS the electric company in the long term.
It's certainly not cheap or easy to deal with the waste in the US where the company(s) (and the taxpayer when it goes bankrupt) has to pay for destroying major river systems because of inevitable waste releases...as happened recently and repeatedly. Only if you ignore most of the actual costs of coal can you think it's cheaper, if you count all the costs, it's FAR more expensive.

ALL the power/energy needed to produce PV panels is reflected in their cost...100%.
Again, to be a bad way to reduce carbon pollution, you MUST assume it takes more carbon to make a panel VS the amount of carbon pollution it saves VS coal power production of the same amount of KWH. That's simply not the case by a long shot, so it does significantly reduce CO2 production, by around 20-30X vs coal. Even in Germany and Denmark, where it's often overcast, they found ....
"solar PV works out to about 50g of CO2 per kWh compared to coal's 975g of CO2 per kWh, or about 20x "cleaner."" In places with better weather, it can be up to 40X.
http://www.mnn.com/green-tech/research-innovations/blogs/how-much-co2-does-one-solar-panel-create

Once again, my electric company doesn't pay me a dime, it trades me power based on peak and non peak hours. Yours on the other hand makes 350% profit on every kwh you produce. I save cash because making (and USING) my own power is FAR cheaper than buying (mainly) coal produced power from the electric company. No "high feed in tariff" required at all. No feed in tariff at all, in fact.
It obviously makes an inroad on reducing carbon because, beyond the panel's production and shipping, there's ZERO carbon, unlike coal which produces more carbon per 10 KWH than it likely took to make each of my 20 panels, meaning they pay off their carbon debt in about 100 hours of sunlight, and are total carbon savers for the rest of their 20 year lifespan.
If we're going to fix climate change, we need to be HONEST about energy production, not compare 150%-350% of the cost of one production source with 5% of another production source to be able to say the 5% source is better.

HAHAHAHAHA!!!! Nuke requires a jump in your bill (even with the HUGE government subsidies the nuke industry gets at every step), but it's better than home mounted PV which SAVES you >50% off your 20 year power costs without a taxpayer cent?!?!? Please think about that.

I'm not basing my figures or thoughts on any study, but on my own personal, long term, economic experience with a system.
As someone who purchased a solar system for purely economic reasons, and has found it to be a HUGE cost saver over buying coal/nuke power from the electric company, all without counting subsidies at all, and even considering I paid top dollar for my system and have battery backup (that produces nothing but cost thousands), I'll simply say you're completely wrong in your assessments based on my own dispassionate, no child having, purely economical experience and leave it there.
I'm happy saving 50% of every power/dollar, you are accepting of giving away around 80% of your power/dollars to the power company. That doesn't make solar unworthy, non-"green", or economically unviable, it makes it a TERRIBLE choice for YOU because you're doing it wrong, and your electric company is punishing you rather than incentivizing you.

/off-topic & longish

I'm not trying to belittle you or anything, so please don't misinterpret the things I'm about to talk about. Regarding your supernatural experiences (which to be perfectly honest IF they do exist, and that is a big if) there are a few problems with them or rather that type of "belief". If it really did happen to you, then it wouldn't be very hard to see why you would believe in religion or be spiritual in a very strong sense of the word (though it depends I suppose on just what you experienced, or what "they" experience).

But, if your faith can be helped along by these type of events, then it would be the type of thing that science should be exploring. I know people will clearly state that you just "can't catch these events", but to be honest, if your body is able to see, hear, smell, or sense it...any number of scientific tests could as well. But, the problem is: when do they happen, how do they happen (by what mechanism, i.e. sound, smell, sight, etc...), and to whom will it occur (and even where will it occur might be a justified question too).

Eventually this should become something, even if on the "fringe" of science or rational belief, should become a real talking point...recognized by all. Simply because, eventually scientists must experience them too, or those with no faith or belief at all...

But, this is why I ask what kind of "event" did you experience?

I suffer from Narcolepsy. With this, I suffer nightly from huge attacks (around 3-15) sleep paralysis events. These events come in ALL sorts of flavors, and since it is from Narcolepsy it doesn't necessarily have to happen at night--like ghosts, or alien abductions (I mean, is it not a good question to wonder why these things almost always happen at night--oh, and the animals don't seem to be involved too much in this stuff for some reason as well). I also (and this is the real winner right here) suffer from, more or less, permanent bouts of hypnagogic hallucinations (typically they happen just as you are about to fall asleep or as you are waking up--with me, they can occur as soon as I'm getting tired). I also have severe Sleep Apnea, just to make all of this more "grandiose"...

Sleep Paralysis is something that was reported constantly even in the Middle Ages; a great painting named "The Nightmare" depicts someone that is actually going through one of these events. This is the actual foundation for succubi, demons, and even angels that visit people in their sleep--these people will feel unbelievable things, things you simply do NOT feel in normal day life...thus many believe a supernatural event has just occurred. The first one I had was when I was just waking up, for some reason I was petrified, couldn't move (and barely breath). Then I looked around my room. It was early morning so I could see in my room, in the corner of my room sat a dark humanoid "solid" shadow. From it emanated a feeling of pure, utter evil (which is were you get a supernatural feeling to this; because for one you do not see "humanoid shadows", nor is it possible to "feel" evil). Eventually I snapped myself out of it and later woke up. It left a stark impression upon me. Later my mind figured out somehow that if I relaxed in these moments, it ended immediately--meaning that I started o become somewhat lucid during the majority of these. I remember my friends and family always saying I was weird or that I scared them sometimes, because I would sleep with my eyes opened--well, this is part of that problem (like I said, I could see my room...everything seemed for the most part, real; it's like being awake and partially asleep--in a dream--at the same time).

Onto my real problem: Hypnagogic Hallucinations. I have no doubt whatsoever that EVERYONE that believes or rather has experienced ghosts/haunting(s), alien abductions, angels, demons, people yelling outside, dogs barking, your phone ringing when it hasn't, and "you name it, because EVERYTHING can happen in this category"... I suffer from this so much that the things I experience now are just a joke to me. Things grabbing me, my body changing shape (and YES you do "feel" the change), all manner of sounds (which is the most annoying; sometimes it sounds like someone has called my name...so I have to go check, it's very frustrating). Then combine this WITH a Sleep Paralysis event (and trust me, it does happen, but it it rare), you get an epic "light show".

So, this is why I asked you what type of supernatural event did you experience. Because, you may want to remember (this is JUST some things Narcolepsy can cause; other medical issues, medications, etc... can cause the same issues if not worse, more pronounced in certain ways and even causing certain changes in behavior, sensations, and feelings) that just with Narcolepsy I run into these issues--sleeping disorders are possibly responsible for a LARGE assortment of the "supernatural" issues you see out there. Then add in the countless number of other things that also affect our bodies and it isn't far fetched to soon realize that you just may have to hold onto what science has proven--only--or you may get lost.

I cannot say that this is you. I will not either. I don't pretend to know your experiences. But, I can share mine... The first Sleep Paralysis and or Hypnagogic Hallucination (as I have been able to move in a few Sleep Paralysis events...but very rarely; if I can though I move slowly) event I had, believe it or not, was when I was around 8 or 9. I imagined that I woke up in the night, turned and looked under my bed (it was a sleepover, so I was on the floor that night) and I saw a pair of red glowing lights, shaped vaguely like eyes looking at me. I kept looking at it, trying to figure out what it was, but very quickly it "blinked" and I knew it was alive. I was scared enough that I simply turned my back from it and tried to go back to sleep. The fact that I simply just turned my back to it and went back to sleep...is proof that it simply wasn't even real.

Had that BEEN real, I would've jumped up, flipped the light on; told everyone in the room and gotten my parents in the next room... But, it felt extremely real. Even to this day, the only thing that makes me realize it was fake was HOW I handled the situation...that is it. In fact that is usually the best way to tell reality apart from a dream (or hallucinations caused by enhanced REM cycles--REM cycles that start even while you are awake). You simply do not act like yourself in a dream, period.

I'll agree with you otherwise. I was definitely smothered by religion and it "stunted" me. It didn't cause me to hate it as much as many might think, but I became extremely wary of anything to do with it.

Great post. Brings closure to a 19 year long argument with my wife on knuckle cracking. Does anyone have a video that proves pubic hair doesn't defy gravity and jump up onto the kitchen counter when walking around the house in the nude?

Though, I have to say, thanks to sufficiently vigorous swing dance training, I can now jump up and down in a regular bra without crying out in pain. I was thrilled when I discovered this new soft-landing skill.

Fantastic. Bravo.

Love that he (apparently or actually) filmed at the same arches Rick Astley used.

Too bad they cut it short. I would've loved to see Jordan Peele jump up and bounce off the chain-link fence and do a few 360-degree spins.

K, I read Tucker Max in college. There's a much more offensive and disgusting story about a girl's first anal experience where Tucker empties the entire bottle of lube up her butt while his friend is in a bedroom closet filming it.

Too much lube, it fires out like a lube-shit volcano, his friend vomits, stumbling out of the closest from the stench, and all three of them end up tangled up in the middle of a shit-lube comforter on the ground.

How does he do it?

xxovercastxx says...

It could be as simple as he knocked the thing over, or sneezed, or a cat jumped up onto the table. But yeah, cuts are going to arouse suspicion in a video like this. He should have reshot the whole thing instead.

Stormsinger said:

You've clearly got the right explanation, but now I wonder just why he had the video cut in those two places. All it did was add yet another opportunity to cheat (which is all that the near-triangle gimmick is, really).

Eric Hovind Debates a 6th Grader

shinyblurry says...

My justification is simply that it has a good track record. If you are really trying to say that I am unreasonable to assume that all physical laws will remain more or less unchanged for the next five seconds then you demonstrate your own stupidity.

The main problem with your justification is that it is logically fallacious. You're still using circular reasoning. Your evidence that the future will be like the past is the past. Is it correct reasoning to use logical fallacies?

You haven't demonstrated that we need to know anything with absolute certainty. Is there any practical value to it?

Can you show me one instance where knowing that something has been the case in every conceivable instance since the dawn of time is just too vague for you?

Things seem to hum along just fine under the crazy assumption that breathing in and out is the way to go.


Well, the thing is, we live in a world of certainty, not uncertainty. What this means is that you are living a double life of sorts. You are uncertain about everything in theory, but of course you never live that way in practice; you expect everything to continue as it has from the beginning of the Creation. You expect that when you jump up you will come back down again. You expect when you say the words "juniper tree" that the sound waves will carry those words to the other persons ear, and they, using universal rules of logic, will comprehend what you're talking about. You are living according to the ideals of a Christian worldview, but simultaneously denying it with your atheism.

Did you know, for instance, that the idea in science of nature being lawfully ordered is a Christian one? It was supposed by 12 century Christians who believed that the Universe was governed by Gods laws, and that we could suss out these universal laws by investigating secondary causes. Here is some of the history of all of that:

http://bede.org.uk/sciencehistory.htm#introduction

So this world of certainty we live in is based in no small way off of Christian ideals and principles. You could not actually justify any of it unless you invoke an omnipotent God who created and maintains all of these things, and will continue to do so. So, the argument is the impossibility of the contrary, which is not only a denial of the world of certainty that we live in, but also the loss of any basis for rational thought.

Water drops floating on water

dirkdeagler7 says...

I imagine it's a result of various forces and circumstances (I don't think it's a coincidence that the droplets were soapy water which would increase it's surface tension/bubble strength).

Also keep in mind that a droplets surface would be a mesh of the outermost water molecules held together by their polar attraction. As the sphere bounces and moves its surface would have mini waves and ripples along it that would push against and then move away from the molecules on the water surface below it as the kinetic and polar forces acted.

If you imagine that every sphere of water had portions of its surface moving away from the water surface below and then oscillating back towards the surface while the molecules on the spheres surface that had been touching the water surface below would begin to oscillate back into the sphere.

This would create many points of contact oscillating against and away from the water surface below and thus there might not be enough contact/pressure between the 2 surfaces for it to coalesce at any given time. Imagine bugs whose feet are tiny enough for them to "stand" on water due to surface tension and the principle would be the same. It'd be like an infinite number of these bugs legs jumping up and down on the water at a microscopic level.

Also I'm not familiar enough with how water molecules align themselves while at the surface of something so perhaps the alignment of their atoms helps as well?

Thats all a guess though I'm sure you could google the real answer.
