Certainly first generation crop based biofuels. Algae based fuels are not as bad, but they need lots of work and there are better alternatives (the energy conversion efficiency for photosynthesis is low). The frightening realization is the use of these first generation fuels - notably corn based ethanol - probably increases atmospheric carbon dioxide.
Sadly every state has two senators, so the US is making some costly and stupid mistakes. All three of the major presidential candidates have said very foolish things and are suggesting dangerous programs. This is nothing more than a welfare program. If we were interested in energy independence, there are many other things that make more sense. Sadly patriotism is just making sure you are shopping these days.
Two Peels. Basic, two cycle (heavy pollution and inefficient), light, small ... I don't think my 2 meter friend Colleen would have much luck here.
now how many cup holders can you put in one? If you wanted something small and efficient, take a 3 wheel bike, put an electric motor in it and make a body. Maybe if gas goes to $10 a gallon we'll see some cleverness.
There are those that would argue that the US has done some pretty bad things and such efforts have a bit of the pot calling the kettle black, but it is reasonable for individual citizens to act and hold countries as well as the companies involved to a standard.
