Electricity use in the US is such that each person would need 100m^2 of panels to supply their average demand over a year to supply around the 1e13kWhrs needed (with incident solar radiation averaging 250W/m^2 and conversion efficiency of 16%).
There will still be transmission losses - An apartment block with 100 people? Well, that will be an acre of solar...
I would suspect that over time the lack of tension on the muscles around the joints (especially the knee) will cause the joint to slacken up, eventually causing them not to pivot correctly.
Gosh I hope it works long term, but I doubt that the joints will adapt...
Yes, I agree and understand 100%, but I have never built a runway in my back yard. Perhaps you work in broadcasting or telecoms?
As per your second paragraph, for most people they do not have to take account in their daily lives that the earth is not flat... Heck, even when working with raw GPS data from runs and cycles I can approximate the globe with a 2D space with difference scales on the X and Y axis, to allow for my being 47 degrees south...
I know that the earth is round, but does it really make a difference? Is there something that you can do in your daily life where the curvature of the earth needs to be accounted for?
We all know that Relativity is more accurate, but who even needs Newtonian Gravity in daily life? You drop things and they accelerate at 9.8m/s/s, And I can't get two bricks to stick to each other with their mutual gravitational attraction.
Can you go out in your back yard and prove that the earth is round? I'ld like to hear your method. And if you can't, why can't you?
I say good on them for questioning what they perceive as dogma. I'ld rather that they were flat-earthers than selling herbal remedies...
... is available here. It has lots of interesting information, allowing you to substantiate statements like "If Nuclear generation was increased 3-fold solely to generate H2 for Automotive use, it would only make just over 1/3 of the current energy used in transportation.". I can not see solar curtains fitting in there anywhere at all...
In the US electricity is about half the residential energy usage (Natural Gas being pretty much the other half), and in total is only around 20% of the total US energy usage. To make things worse, over 50% of the energy is lost in conversion, transmission, transport and other losses. For example, 1KWhr worth of coal burnt in a power station does not deliver 1KWhr of electricity to the wall outlet in a house.
For each unit used at home, another 4 units are used outside of the home (in transport or industry) and another 5 units are 'lost'.
If everybody was able to make better use of their power - including industrial & commercial users - most of the social and political drivers for alternative energy would disappear.
Which brings me back to the starting point. If you are able to reduce your energy consumption to the point where renewable can supply it all, then your energy usage will be so small that you won't have a big economic driver making you consider renewable in the first place.
It will be an expensive, altruistic lifestyle choice.
Agreed, but I strongly believe that it is impossible for the energy consumption to get to a point where renewable are able to provide for the energy needs of the population.
The current world's energy consumption is 1.5e15W. The global average of incident energy is 250W/m^2. If we are able to convert and distribute solar energy with 10% efficiency it will take 60 million square kilometers - or over one third of the world's surface area of 150 million km^2.
Renewable will never be able to meet even a small portion of the world current energy usage - if you disagree please explain how the energy usage of the average US citizen of 10KWhr every hour can be meet?
Currently hydro and other renewable account for only 6% of that figure.... even if renewables increase 10-fold, you still only get half way there!
Why can't people see that if we become energy efficient to the point where solar is viable for most people, then you don't need solar!
Solar power can never reliably provide all your energy needs - cooking, water heating, gadgets, lighting and so on.
Say I lived in London, the average solar energy on a an area in London is 109 watts per square meter. Given a spectacular 20% efficiency, a solar cell will get 22W per square meter over the year.
Last month my family averaged 1.4KW (we have a new son, and had the heater on most of the time, but we do use a wood fire too!). Even if I were able to store all my summer power to use in winter, I would still need 60M^2 of these magically efficient solar panels.
In December, the incident solar radiation averages only 22W per square meter (yes, London must be a grey place in winter). I would need to cover 600M^2 to get enough power to meet my average demand.
And given that I would need storage capacity for a bad storm, maybe 5 days usage (168KWhrs). A 'car battery' sized Deep Cycle Cell holds about 2.4KWhr, so I would need 70 of these!
There is no way on earth that each London household can have 600m^2 of solar panels and 70 deep cycle batteries. And I don't even start to allow for an electric vehicle
Solar will not save us from needing other forms of power - especially not solar curtains. Who's dumb idea was that?
This has already happened with popular media like TV.
I think the answer has to be yes. Watching a rape or murder has got to warp people.
You can't say "advertising works", and then say showing graphic violence has no effect.
And I don't understand American TV's hang-up about showing nudity. Why do people watch graphic violence without getting upset, but you can't show a nipple.
Why are 'naked dead bodies' allowed to be shown in crime based TV shows, but not live ones? What's with that, eh?
Yes, and if you have lots of interactions in a small space, you could just make the local time run slower.
Oh, and if it just gets too hard to simulate it, you just make it not available to the rest of the simulation , and only model the important global properties of that area.
It saves the hassle of the analogue wiring, and I can listen on the radio alarm clock and in the garden shed.
They work under Linux as USB speakers, so I've got a MySQL DB of my MP3s and the music queue, a Apache/PHP front end to queue up the songs, and I use a shell script and mpg321 to take the tracks from the queues and play them. And if nothing is queued up, I've got a semi-random music selector program to keep the sounds coming - if you punt a song in the Web Gui, it gets played less often.
Cost for a 3 FM channel system? Under $150 for the hardware, and half a day's coding.
The explosion will change the shape of the orbit, but the orbit of any debris will still pass through the altitude where the explosion occurs. There is no way to achieve 'round out' a orbit without thrust (something that the debris will not have..)
Orbital velocity is around 7km/s, so it is going to take a big bang to radically alter the orbit. I wonder how much momentum an explosion in a vacuum can impart... it would have to be pretty close. If it just crashes into the target then the average velocity of the debris will then be lower than what the target was traveling at (since the missile will be sub-orbital).
Whatever happens the smaller bits should experience higher drag-to-weight ratio and deorbit quicker - there is still drag in the very low earth orbits. So if this bird is in a useless high drag, low earth orbit, smashing it will not be too bad.
But smashing things in high orbit is not very nice though!
In general, to "troll" means to allure, to fish, to entice or to bait - usually wanting to slam the other person.
I can see two reasons why your post was a troll.
1. Ones persons verifiable personal contact to an act of terrorism is not "utterly meaningless" - it is at least one datum. I guess if I were to call a fact that your school buddy lost a leg in 9/11 "utterly meaningless" I would be marked as a troll too.
2. Regarding the media - I think from my post it was quite clear that I don't think that muslims are bad people, and I gather you don't follow Fox News... headlines line "KUWAIT CITY -- Valentine's Day is just three days away, but one Muslim politician is heading up a committee to make sure it goes completely ignored.". What sort of reporting is that???
If I were to say something like "And what about those Christian American paediophile soldiers who pack-raped a 14 year old Iraq girl then shot her and her family in Mahmoudiya - those sons-of-a-b@#$h Americans are evil". That, my friend, is quite a worthy troll.
Notice how the "those" in that sentence refers to the the five soldiers and is 100% true (assuming they have been . Notice how the "American" adjective seems to tar all Americans with the same brush. Do you disagree with me about those Americans being evil? If not, do you support murder and rape? That is the Fox News way... the American "Have you stopped beating your wife yet?" School of making News.
Um, You missed his point. All of these groups 'could' be treated in the same was as you currently view Muslims - there are justifications in history!
Were you in London while the IRA were bombing? I went to school with somebody who who lost a leg in an IRA bombing. Which is far closer to me personally then any body killed by a Muslim terror attack.
In some cases reputations are earned. In this case popular media is portraying all followers of the Muslim faith as being fundamentalists - and some people less capable in critical thinking are believing it.
Surely it is everybody with the name "Bin Laden" that should be screened!
The 8x86 in 16 bit 'real' mode had a 20 bit address space, allowing access to 1MB. The 24 bit address was the contents of a 16 bit segment register shifted left four bits plus the memory address.
With a 16 bit address space you can only address 64K of memory, without using page switching or some other form of banked memory. Most 8 bit micros (Z80, 6502...) had a 64 bit address space.
If I understand this right, it is saying that from an external frame an object will not cross the event horizon.
But from a local frame of reference you will, except due to the distortion in spacetime time will be running infinitely slow - the upshot being that you will cross the event horizon at the end of (external) time or when the black hole (and event horizon) evaporates.
Is the far side of an event horizon a spacetime disconnected from the external space time? Does it really exist at all? I wonder if the gravitational signature of a black hole is that of a solid sphere or a hollow shell?
Ah, that makes me feel better... I'll just clear my Browser's cache next time I am planning a crime.
By the way how are things going down at the station's computer forensic lab? do many suckers fall for your misinformation?
...is Serial Comms.
I've just spent two hours hooking up a medical blood analyzer (speaking RS232 - and this is a brand new $$$$$ device). The customer had it completely FUBARed. The plug was wired wrong, the fly-lead only had 4 wires crimped, the serial port server was miss-configured....
How many IT people know what a DCE and DTE device is, how XON/XOF works, and how hardware handshaking works? Not many... if any.
Oh, and I guess that H2 production would be an exothermic reaction - with a large amount of energy wasted in the process, and potential for fire if the 'fuel' gets too wet. The best use I can think of for this is "spit on it" hand warmers, or a cigarette lighter that 'runs on water'.
It seems to be about as useful as using glow-sticks for street lighting.
But if you really want to make it unpopular call the reduction of the Aluminum oxide back to a metal "fuel reprocessing"...
Intelligence and free will is not reserved only for humans. One of my dogs understands very well how water gets into its bowl, and other complex processes.
She was cunning enough to move the big weight away from the vertical freezer, remove the tub of berry ripple icecream, close the freezer, eat the ice cream and then frame the other dog by putting the container on his bed. That takes a lot of intelligence, free will and planning for the future consequences of her actions.
We know it was her because Kuzak is just too stupid to even plan anything nearly as cunning, while he was kicked outside she was the one who curled up on our bed put her head under the blankets and then THREW IT ALL UP, leaving it for us to find at 11pm that night...
Why do people thing that timeliness and quantity is the same as quality when it comes to human-to-human communication?
People have only so much capacity to take in information - why would I want to fill my life with junk. One well reasoned, concise and consistent message (be it email, phone, or face to face) is usually priceless compared to hundreds of unfinished ideas, mumbles or rants.

Most of everything has to be on auto-pilot, we just don't think that fast.
But we are in control of the autopilot. We program our own responses allowing us to push as much as possible out of the higher levels.
Don't believe me? Then learn to juggle five balls. It is more than you can deal with, but still you can still learn how to do it.
