wireless power transfer
MITの物理学者のMarin Soljačićて人が
ワイヤレスの電力伝送技術を開発したみたいです。
以下は彼のHPから抜粋。
In last few years, our society experienced a silent, but quite dramatic, revolution in terms of the number of autonomous electronic devices (e.g. laptops, palm pilots, digatal cameras, household robots, etc.) that we use in our everyday lives. Currently, most of these devices are powered by batteries, which need to be recharged very often.
This fact motivated us to think whether there exist physical principles that could enable wireless powering of these and similar devices.
Results of our research on the feasibility of using resonant objects, strongly coupled through the tails of their non-radiative modes, for mid-range (i.e. a few meters: e.g. within a room, or a factory pavillion) wireless power transfer applications seem to be quite encouraging.
今回達成したのは電力源から2メートル先にある60Wの電球をワイヤレスで電力供給したとのことです。
研究を始めたきっかけはiPodとノートPCをいちいち繋いでぐだぐだするのが嫌だ、と地元紙？の紹介記事には出てますが、ホントに達成できたら部屋からコードが劇的に消えますね。
