Discard bulky power adapter! Notebook can be built up

As a flagship notebook portable equipment, since weight loss itself, what the bulky AC adapter can be used for? Japanese scientists have developed a new achievement. According to Nikkei BP reported, Osaka University and Kyocera, Roma, Murata will jointly develop an AC adapter miniaturization technology. By improving their use of each module wiring and miniaturized circuit board and a semiconductor element, its size will be reduced to 1/20 now and can be built into the notebook.
 During this cooperation, Kyocera is responsible for circuit panel and Roma is responsible for semiconductor device, Murata is responsible for capacitors, which is their problem to solve.
Experts predict that within three years the technology will be commercially available, then you can lose the "disgraced" the AC adapter.
