I am surrounded by a lot of electronic gadgets such as a PC, cell phone, music player, IC dictionary, portable game, and so forth. Most of them are using a rechargeable battery and they need to be charged from the power line. I have four outlets in my room which are far from enough. In order to compensate for these insufficient outlets, I'm using a lot of power taps and there are several taps like this picture. We call in Japan this kind of wiring "octopus wiring" because it looks like legs of an octopus. This octopus wiring is said to be dangerous because it might cause fire. But It is so convenient and necessary for me that I can't stop using it. As you know in most gadgets, how to supply the power is the last remained problem. The Li-on battery is surely a great answer, but it needs annoying charging process which is even dangerous. So I'm urgently desiring that the fuel battery comes into practical use as soon as possible.
