That's all, folks!

I think he's referring to the amount of energy available in a given square of sunlight. You can't get more energy out of it than already exists, no matter what the efficiency.

Sounds simple. Step 1: Invent 100% efficient solar cell. Step 2: Invent power beaming. Step 3: Profit!

I'm pretty sure you are right... the earth is almost 25,000 miles in circumference, and rotates once in 24 hours, which comes out to just over 1000mph at the equator.

Slashdot effect strikes again!

If only you had multiple personality disorder you could sell yourself as an entire development team! They say I have megalomania... once I'm emperor of the world I'll show them a thing or two!

I used an HP Ipaq for years, then switched to a Windows Smartphone, and now finally to an Android smartphone. A Kindle is great for battery life and daylight reading, but way too big to carry around all the time. The smartphone has drawbacks... bad battery life, small screen, but can be read in all but the brightest lighting conditions, and mainly, I have it on me ALL the time. I never know when I'm going to get a few minutes to read, and since I always have the phone with me it is very convenient. I have read hundreds of books this way in the last 10 years, in line at the store, in the bathroom, waiting for a pizza, waiting for updates to download on a client's computer, etc.

This was my choice too... I did a search to see if anyone got there first and sure enough... I usually love post-apocalyptic stories, but this one had a very depressing ending.

A lot of Andre Norton's stuff, like "Daybreak 2250AD"...I've loved post-apcalypse stuff ever since, or "Breed to Come", "The Zero Stone". I could go on for hours.

Oh, and, while not really Science Fiction, "The Mad Scientists' Club" by Bertrand R. Brinley was pretty cool.

...when I was a kid were "The Runaway Robot" by Lester del Rey and "Secret Under the Sea" by Robert Silverberg. I think I still have them in a box somewhere.

I get my kicks ABOVE the shell, sunshine!

Viagra.

Russia still hasn't managed to do what the US did in 1969 (43 years ago). When they actually land a human on another celestial body then they will have cred.

L. Sprague de Camp - "Lest Darkness Fall" ...Probably my all-time favorite. Andre Norton - "Daybreak 2250 AD" or "Star-Man's Son" ...I had a thing for post-apocalyptic stuff when I was a kid. i secretly hoped for a nuclear war so I could live in such a world! Brian Aldiss - "Starship" Eric Frank Russell - "Wasp" ....someone mentioned this one earlier. Also "Men, Martians, and Machines" Niven and Pournell - "The Mote in God's Eye" and "The Gripping Hand" Larry Niven - "The Integral Trees" and "The Smoke Ring". Also all of the "Ringworld" books. Harlan Ellison - "Phoenix Without Ashes" ...they made a really BAD TV series (The Starlost) based on this book. Too bad, because the book was really good. Steven Gould - "Wildside" Kenneth Bulmer - "Keys to the Dimension" series. E. C. Tubb - The "Dumarest" series.
