I wonder when netbook makers will incorporate 3G in their products. Seeing the specs of some smartphones I found myself wondering where the line between them and netbooks should be drawn. Apart from screen size, the difference is small. So, if Asus, Acer and othernetbook makers start to include a slot for a SIM card, the difference will definitively only be in size.

We don't need to convert cropland into pulpwood production. The idea, IMHO, is to use crop waste (which is discarded) into ethanol.

Much of sugar-cane production isn't used for ethanol, but burned because it's cellulose, and bacteria find it hard to degrade cellulose into its component sugar blocks.

If you get a cheap way to do this, you can produce much more ethanol per square meter. Be it from beet, soy, rice, sugar-cane or the grass you cut from your lawn.
