Future fuel
TRE14 future fuel

The equations behind burning fuel are extremely difficult to understand on the micro-scale. Scientists studying combustion must rely on guesswork. With Titan, scientists can model the chemical reactions for combustion of relatively simple fuels like alcohol and butanol. But because gasoline and biodiesels are complex fuels -- the molecules inside are longer and thus trickier to model -- more and more powerful supercomputers will be required to parse them.
