I think that roads are ways for people to get places, in the cities where cars have been limited or banned all together, the city centres have prospered, contrary to the naysayers.
Just because you can afford a car does not mean you have to buy one! even if you have one you don't have to always use it. Think of the parking issues in major cities eg New York, or Beijing for example has 1/3 the number of car parks for its estimated 5 million registered cars on its roads as of 2011.
I doubt it, car sales are dropping, all over the developed world. More and more people are walking, riding bikes and talking public transport. In all the cities I have lived(Launceston, Brisbane, Melbourne and Shanghai) in bicycle use and infrastructure has increased while I was living there. Also there will be big changes when the self driving cars start going commercial, some of the above problems may be solved. Studies have proved that traffic jams are often caused by the inconsistent braking and acceleration of drivers. With self driving cars, they maintain a constant speed, and optimally brake and accelerate, thereby reducing congestion. Plus other interesting ideas could occur, such as sending your car home after dropping you off, or sharing cars, so that they are almost like taxi's, that arrive on time. All that parking space can be re-allocated to bike paths or more car lanes. see car sales drop. http://www.nytimes.com/2013/01...
isn't this already know? how is this different to a light sail?
SternisheFan points out that there is a great new panorama made from shots from the Curiosity Rover. "Sweep your gaze around Gale Crater on Mars, where NASA's Curiosity rover is currently exploring, with this 4-billion-pixel panorama stitched together from 295 images. ...The entire image stretches 90,000 by 45,000 pixels and uses pictures taken by the rover's two MastCams. The best way to enjoy it is to go into fullscreen mode and slowly soak up the scenery — from the distant high edges of the crater to the enormous and looming Mount Sharp, the rover's eventual destination."
are you so sure of that MIT has done it http://web.mit.edu/newsoffice/2007/wireless-0607.html
unixfan writes "Georg Greve, developer of Open Document Format and active FOSS developer, has received a knighthood in Germany for his work. From the article: 'Some weeks ago I received news that the embassy in Berne had unsuccessfully been trying to contact me under FSFE's old office address in Zurich. This was a bit odd and unexpected. So you can probably understand my surprise to be told by the embassy upon contacting them that on 18 December 2009 I had been awarded the Cross of Merit on ribbon (Verdienstkreuz am Bande) by the Federal Republic of Germany. As you might expect, my first reaction was one of disbelief. I was, in fact, rather shaken. You could also say shocked. Quick Wikipedia research revealed this to be part of the orders of knighthood, making this a Knight's Cross.'"
The Chinese stuff isn't an exact copy is a modernized version, a lot of work has gone into it. They didn't buy the rocket they built it them selves, thats something I'd say.
yes gravity wells that block radiation, that at least in the short term is difficult to block.
is twitter that popular? i hear a lot of people talk about it(and websites) but I don't actually know anyone(outside celebrities that use it)
