Comment Re:Only 8%? (Score 1) 655

Fortunately the validity of the scientific theory of Global Climate Change doesn't rest on whether, or not, Black Parrot provides a citation for every comment he/she makes on Slashdot.

Actually, it does.
This absence of evidence is evidence of absence of validity.
And your answer is evidence of your incompetence.

But why stop at evidence? I can prove that I am right:

Comment Bright ovens (Score 1) 1080

I use light bulbs in the winter, because winter is dark, which summer is not.
I also use electric ovens in the winter, because winter is cold, and electric heating is the only allowed in my apartment.
So: I only use light bulbs when I also need electric heat, which the light bulbs also make.
The result: I only need one oven, because I can heat the other rooms with light bulbs, and get a lot of nice light in the process.
In other words: Light bulbs are ovens that I must use, but which give off nice light as a byproduct.

And light bulbs have a nice reddish spectrum, which do not mess up peoples sleep cycle so much.

You seem to understand it.
A defect of this method is electromagnetic radiation, which means that undetectable eavesdropping can be done, and the speed of light and relativity, which means there is no simultaneity of changing of resistors.
In other words, Eve can eavesdrop by passively listen at two different locations on the wire, thus seeing differences in Alice and Bobs signaling.

Comment Sundiver (Score 2) 502

In the book Sundiver by Robert L. Forward, a research ship traveling inside the Sun gets its drive sabotaged, and they escape by using the cooling laser as a drive, freezing everyone aboard.

Lasers are today used to cool to a few milli Kelvins, and below, very close to absolute zero temperature. The reflected colour of the laser is a little bit less pure, as the thermal vibrations are removed by increasing the entropy of the laser light.

The same principle is going on in this light diode.
