Gasoline substitutes from water - again
Remember what I mentioned about making substitutes for gasoline using water and a carbon source? The methods I talked about used ethylene or coal, but Autoblog Green reports that scientists have done one better and found a way to make methanol directly from water and carbon dioxide. Of course, you need an external source of power to drive their device, called a methanol fuel cell, in reverse. But since this device just recycles the products of burning hydrocarbons, it does not necessarily need any fossil fuels at all, unlike the methods I wrote about earlier. Plus, it gives us something to do with all that pesky carbon dioxide.
