Able to rotate on a graphite disc magnet, to generate electricity.

Aoyamagakuindai team has succeeded in taking advantage of the properties (graphite) to repel the magnet, the magnet is rotated on a disk of graphite, graphite to generate electricity. That can be applied to power generation technologies with low environmental impact at low cost.

Graphite is also used in pencil lead. Team of colleagues and Kobayashi Abe university professor, was placed one centimeter disk of graphite of 0.25 mm diameter and thickness on top of the permanent magnet. Then, the disk is now floated at a height of about 0.6mm.

Was shed sunlight collected by a lens on the end of the disk, we have rotated at 200 revolutions per minute or more. Has changed the nature of the graphite temperature of the portion may shed light up. Momentum when the disk goes down slightly by the repulsive force between the magnet is weakened, sink that has brought a turning force.

By all means, I want you to put into practice in some form for practical use, but further research and development will be required.



黒鉛（グラファイト）が磁石と反発する性質を利用して、黒鉛の円盤を磁石の上で回転させて、発電させることに青山学院大のチームが成功した。安価で環境負荷の少ない発電技術へ応用できるという。
　黒鉛は鉛筆の芯にも使われている。同大の阿部教授と小林研究員らのチームは、永久磁石の上に直径１センチ、厚さ０・２５ミリの黒鉛の円盤をおいた。すると、円盤は約０・６ミリの高さで浮いた状態になった。
　円盤の端にレンズで集めた太陽光を当てたところ、毎分２００回転以上で回転した。光を当てた部分の温度が上がって黒鉛の性質が変わった。磁石との反発力が弱まったことで円盤がわずかに沈み、沈む時の勢いが回転力を生み出した。
　実用化に向けて、更なる研究開発が必要でしょうがぜひ、何らかの形で実用化して欲しいですね。
