The inventor of the Gravia lamp has also issued a retraction, stating that estimations and decisions made during the design process were incorrect (<a href="http://pesn.com/2008/02/19/9500471_Gravity_Lamp#Inventor_Concedes_Error" rel="nofollow">http://pesn.com/2008/02/19/9500471_Gravity_Lamp...</a>). So, while the other ideas presented here are neat, the Gravia lamp should be allowed to fade back to the land of ideas.ZoeWed, 03 Dec 2008 00:02:23 -0000
