Dear Nobel Prize Academy, With all due respect, after four years research on LED and Lighting I haven't come across with a single light source that saves energy. Besides the cancer potential of the blue-hazard, the invention is revolutionary. Thank you. _______________""The Nobel Prize in Physics 2014 was awarded jointly to Isamu Akasaki, Hiroshi Amano and Shuji Nakamura "for the invention of efficient blue light-emitting diodes which has enabled bright and energy-saving white light sources"."" _______________ http://www.nobelprize.org/nobel_prizes/physics/laureates/2014/
