Very little.
In 2030 we would just need 496,805 square Kilometers.
Why not beginning NOW?

LED? No, OLED
The appearance of LG's 15-inch OLED TV at IFA 2009 is a small (but significant) step on the road to replacing LCD, LED and plasma technology.
Organic Light Emitting Diode (OLED) technology is poised to oust LCD just as LCD stuck the knife into the CRT.
An OLED panel consists of a layer of organic, light-emitting material sandwiched between two conductors (an anode and a cathode). This diode layer emits light when an electric current is passed through it. A TV panel features thousands of OLED pixels mounted in rows and columns onto a TFT array. This is referred to as an Active Matrix OLED or AMOLED display.
Advantages:
No backlighting required
OLED outperforms LCD and LED
Sony, LG and Samsung love OLED
OLED is available now (albeit in small sizes)
OLED can be 'flexible'
OLED can be 'transparent'
But:
OLED is expensive
It is not a perfect Technology
OLED displays are expensive to manufacture
There are concerns about its lifespan

Vaccine from China?
"Scientists in China claim they have produced swine flu's first "magic bullet" - a vaccine that prevents the virus in a single dose.
China's State Food and Drug Administration said it approved the vaccine Sinovac after testing was completed last month.
It is the first "one shot" vaccine to be approved by the Chinese regulator, and is said to be effective on people aged between three and 60 years old."
No, thanks, I think I prefer the flu.

The secret of beauty is knowing how to look beautiful
Once I decided to hide all mirrors in my house and, where not possible, to walk in front of them looking on the other side.
It was because I didn’t like myself and I didn’t want to see my reflection.
That lasted some time.
Then one magical day I changed my hair style and found a very nice dress which fit me and showed the best of me, hiding the worst, and I began liking what I saw.
I realized that looking at the others and trying to be like them didn’t work for me.
Because they were tall and could afford things I couldn’t, and they had curly and beautiful hair, while mine was the opposite.
It is just understanding how you are and making the best out of it that can help to change your look.
If you are a size plus you need special clothes to look your best.
I have skinny friends that can wear (almost) anything they like, but that doesn’t mean that I cannot look as glamorous as them, sometimes, I look even better.
For example.
I like very tight pants, and one would think they are not good if you have a few pounds more.
They look perfect if you are smart enough to wear a larger blouse, that covers what has to be covered.
I like a classic look and would wear a pair of tight black trousers with a very nice linen shirt, not too big, not too tight, and not too long.
I also do not dislike jeans and I prefer the straight leg type, because I am not tall and certainly do not want to look little.
I once overheard a comment of two men looking at me:
"She is certainly not thin, but she is very well shaped..."
Well, that is exactly the point.
And where can you find the right outfit also for "Plus" sizes?

No return ticket to Mars
On The New York Times:
"The most challenging impediment to human travel to Mars does not seem to involve the complicated launching, propulsion, guidance or landing technologies but something far more mundane: the radiation emanating from the Sun’s cosmic rays. The shielding necessary to ensure the astronauts do not get a lethal dose of solar radiation on a round trip to Mars may very well make the spacecraft so heavy that the amount of fuel needed becomes prohibitive.
There is, however, a way to surmount this problem while reducing the cost and technical requirements, but it demands that we ask this vexing question: Why are we so interested in bringing the Mars astronauts home again?"
The logical answer would be: because you wouldn’t find anybody eager to go into a no way back trip.
But:
"If it sounds unrealistic to suggest that astronauts would be willing to leave home never to return alive, then consider the results of several informal surveys I and several colleagues have conducted recently. One of my peers in Arizona recently accompanied a group of scientists and engineers from the Jet Propulsion Laboratory on a geological field trip. During the day, he asked how many would be willing to go on a one-way mission into space. Every member of the group raised his hand.
The lure of space travel remains intoxicating for a generation brought up on “Star Trek” and “Star Wars.”
Conclusion:
"Delivering food and supplies to these new pioneers — along with the tools to grow and build whatever they need, for however long they live on the red planet — is likewise more reasonable and may be less expensive than designing a ticket home. "
I wouldn’t certainly be among them.
But then, I never liked “Star Trek” and “Star Wars.”
