The factor of 500 refers to the absorption only, not to conversion. It is perfectly imaginable to increase the absorption coefficient by such a factor.
A factor of 500 is easily within reach when using other semiconductors with a direct bandgap (Si is indirect). InGaN would be such a material. It could cover the entire spectral range from IR to UV depending on composition.
Actually you don't even need any form of identification for domestic travel (yet). Airlines do not have the jurisdiction to ask for some form of ID.
Don't believe it?
I travelled from LAX to SFO last July and just wanted to see if it is possible. I got send over to a special line for "no ID" people and got searched thoroughly but it was still faster than standing in the normal line. This was on Southwest.
Just try it. It will make a point against the real ID.
Note: I am a white male and was decently dressed but had an evil german accent. It would be interesting to hear reports from people with a middle eastern complexion.
Next thing you know, Porn will be made illegal and some sexual practices you enjoy will get you into jail.

A few months back i flew back from Sao Paolo to the US over Houston. I got thoroughly searched at customs (could not refrain from laughing as the guy went through my old underwear). As the officer saw my digital camera he asked if i would mind him looking at it. Sure as hell i did and told him so politely. He went on to ask me if there was any childporn / incriminating material on it. I said that no, but that there could be my girlfriend naked on there. He said, he would not let me pass without scanning through all pictures.
I am not US citizen and had to catch an ongoing flight, so i had no choice but ask for a complaint form (no answer from them). I was pissed!

The absorption coefficient of Silicon itself ranges from zero to 10^7 depending on the wavelength considered. See here http://www.ioffe.ru/SVA/NSM/Semicond/Si/Figs/145.gif

Amen, not to mention excessive use of parenthesis.
Why, www.girlsfornerds.com of course!

Oh yeah, i feel suicidal.
Well i guess ALT+F4 will do this time.
I did. This works in Germany and Switzerland. Not in United States where i live now though...
What actually ticks me off most is the Spam that lands in my "brick and mortar" mailbox everyday.
Much more of a hustle to get through and a waste of resources.When are Walgreens, Target and other big stores finally going to be flagged as spammers??

What's next, they will read my diary?
Most of the video content freely available online is usually of lower quality or illegal. Makes me wonder how these guys do it:
http://www.watchtvonline.ws/tv/simpsons.html
Seriously, i am downloading episodes at almost 1 MB/sec. I am not uploading anything, so it does not seem to be a p2p thing.
Anybody care to explain how this is possible physically/legally?
I hope they take this site down soon, because i have a job and not enough time at hand to go through 18 seasons of Simpsons!
