Gravity Lamp Grabs Green Prize

jmt(tm) Re:It can't possibly work either (596 comments)

OK, let's go back to physics 101. The device has stored a certain amount of potential energy when the weight is on the top, and a lower potential when on the ground. That's all there is, that's all the energy you can transform into light. Nothing can change that. The only effect (besides added friction) of making it spin around is that you stretch the time in which you make use of the energy. Result: less light, but over a longer time period.

Not that it would even be a bright light if the weight would go straight down...

They take a look at Apple's own documentation, now available at the Mac OS X 10.5: About the Application Firewall page. Their verdict is clear: "Alltogether this confirms the impression created by the initial functionality test. In its current version, this firewall cannot be recommended for practical use.""

It seems that pictures marked as moderate or restricted cannot be accessed anymore. There are ongoing discussions at Flickr. Have verified the issue myself with a German Yahoo! account."
