It turns out that the current state of the art in this has the supercapacitors being produced using *standard DVD drives*!! http://www.nature.com/ncomms/journal/v4/n2/full/ncomms2446.html <quote> Here we demonstrate a scalable fabrication of graphene micro-supercapacitors over large areas by direct laser writing on graphite oxide films using a standard LightScribe DVD burner. More than 100 micro-supercapacitors can be produced on a single disc in 30? min or less... These micro-supercapacitors demonstrate a power density of ~200?W?cm?3, which is among the highest values achieved for any supercapacitor. </quote> - -- ((Udhay Shankar N)) ((udhay @ pobox.com)) ((www.digeratus.com)) -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (MingW32) Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iEYEARECAAYFAlFQOoQACgkQnmFnu1X6uNMcMQCfapN6SnLfdxkYtsSKhvx6ALv+ CfsAn3MVWDRSF6XpZvRsa5n0oXJrcXAi =IZk2 -----END PGP SIGNATURE-----
