I agree with some of your points and will address some of the ones I don't
On wind and solar changing the weather I introduce you to another widespread use of technology that changes weather condition and by a lot more. They are called cities.
On energy use to build things. Most if not all renewable sources produce far more energy then is used to make them.
On land use even if solar is 10% efficient you can generate enough energy from a small portion of the Australian deserts. (of cause you would spread it out)
On transmission losses, place a few appropriate renewable energy sources near big user of energy and you cut losses by a lot.
The person receiving uses one of 2 filters/readers .
Use the right filter and you get the correct bit.
Use the wrong filter and half of the time you get the correct bit and the other time you get the wrong one. This means if you incept the key you can not send the same set of photons on.
Discard the ones that you used the wrong filter on and then compare your key with the other person. (over an un-encrypted line). If there are too many errors then it has been incepted and the key is discarded.
Then using the key you can XOR binary data in a un-decodable stream which can be sent over an un-encrypted line

60W incandescent bulb =
1.26watts light
58.74 watts heat
http://en.wikipedia.org/wiki/Incandescent_light_bulb#Efficiency_and_environmental_impact
Look a how much of the light is shining off the panel and the efficiency of the light->cpu is even better
And is the cpu using all the power available from the panel?
distance driven not cars. although you might need to look at area too.
I have seen statements saying that the US has 500 years of coal left at current usage. and is about 20% of the energy mix.
now if their is a 5.00% annual growth in coal usage that 500 years drops down to 67
simple:
Many universes and we live in just one of them. (random chance)
complex.
the one universe just happens to be the one for us. (something has selected)
Occam's razor is not the she simplest answer but the one with the least amount of assumptions.
oops.
meant to say amount emitted in kg multiplied by amount of heating by a kg
1. How much heating total doe the greenhouse effect provide? 300Kish
2. How much change is predicted? 1Kish
3. Does x = the change predicted
>Trailing
Look at any thing in equilibrium (nitrogen dioxide(A) and dinitrogen tetroxide(B))
Increase A and B will be a trailing indicator .
Increase B and A will be a trailing indicator .
>CO2 being a small part
about 300K of global warming is normal. (space is very cold)
(Numbers picked out of thin air)
297K of non-co2 warming
3K -300pmm CO2 warming
4k-400ppm CO2 warming
>Human Contribution being small
if you can serve 10000 people an hour and 10000 people an hour come there is no problem.
But if 10 more people an hour come then a backlog will form despite those 10 people being less then 1%
1. Atari should pay 3x the retail cost of the GPL code. 3 x $0 = $0
Jammie Thomas did not try to sell the music as her own.
The problem is the average customer does not like the same things that reviewers like.
A game that is very good and is 60 hours length that gets a review of 99 would not suit them.
They used the number of IP's connecting to their server vs the number of purchased games. (it does connect to there servers)

My information shows that they last about 20 years and payback their energy cost in about 2-4 years.
Cost is the big problem though.
According to my data the energy payback is less then 3 years for solar PV.
Lifetimes of more then 20
= 6-7 times more energy made then produced.
The panels need to face the sun not earth.
A nuclear plant could produce twice that on about ten acres.
Is that including the mines?
but if he is authorised to make copies then does his copy imply the rights in that case only.
Hydrogen doesn't escape to space. It combines with oxygen before reaching space.
Helium however does.

the hot coffee case is not as simple as that.

Average of 5 hours a day = total power per square meter = 5Kw
My house + 50% = 30kwh / day
= 6 square meter
30% efficiency
Only about 20 square meters required.
Simple answer.
a one-time-pad is unbreakable but needs keys to be distrubted.
QC is used to send the keys and if it is incepted it can be detected and the key discarded.
In a sense.
A number of Polarised photons are sent.

Quantum cryptography gives you a secure way to pass the key to the person your communicating with.
Wireless communications are not fundamentally incompatible with Quantum cryptography
The stream they are talking about is the key.
The thing is you can only accurately read about 50% of the photons.
When Eve reads the message changes to 50% correct, 50% incorrect.
When Bob gets the photons his 50% will consist of 25% correct and 25% incorrect ones. (assuming true randomness)
When Alice and Bob compare there keys they will see the discrepancy.
Then the 1 and 0 are XORs with the message and then the result is sent.
