Using an ethanol fuel content of 21.2 MJ/L and TTW efficiency of 3.08 MJ per \(\mathrm{km}\), calculate the theoretical travel distance (units of \(\mathrm{km}^{2}\) per \(\mathrm{km}^{2}\) of land) for an E-85 vehicle powered by corn grain ethanol. How does this number compare to sugar cane ethanol and cellulosic ethanol? Employ appropriate assumptions for crop yields and process conversion efficiency.
