Wow! Those cities look amazing. And I do like the sound of digital books actually, I didn't even know what they were until I heard about them on this forum. I also love the feeling of having my own paper book, being able to fold the pages, I even like them smell of them...is that weird? But I am very forgetful, and I have lost a lot of books (after I read them thankfully). So a digital book like that which can hold, what was it, 500 texts? Now, that would be handy! But I also agree that it would be nicer if it was solar powered (although it does seem like it doesn't take toooo much to power it, 10,000 pages on 4 AAA batteries, not bad!)
I have seen in Denmark and other places they are already using wind power. They have windmills spread out across the ocean. I have also heard about people doing research trying to find a way to use hydrgen as energy. Its so available in the air and in water, it could happen someday.
Those Petronas Towers look amazing, that is almost exactly how I imagined the sky cities in my head! And that bridge, I never connected it with the bridge in the sky, although I am sure the bridge in the sky goes on a little longer than 24 miles, right?
