- C1 (one carbon atom fuel - methane)
- C2 (two carbon atom fuel - ethane)
- C3 (three carbon atom fuel - propane)
Banging more carbon atoms into these molecules gets you more energetic fuels:
- C7-C10 (gasoline)
- C10-C16 (jet fuel/JP8)
And when the carbon combines with air during combustion, you get a C02 molecule for every carbon atom ... hence the problem with fossil fuel emissions ... and the potential of Carbon Sciences' approach.
