3) Does this article really answer whether clean fuels are feasible? They say it is in the near future, but I'll belive it when I see it

4) List the fuels on the Comparison chart by octane rating, from lowest to highest:

Gasoline= 86 to 94
No. 2 Diesel = 8 to 15
Biodiesel(B20) = ~25
Compressed Natural Gas(CNG)= 120+
Electricity= N/A
Ethanol(E85)= 100
Hydrogen = 130+
Liquified Natural Gas (LNG) = 120+
Liquified Petroleum Gas (LPG) = 104
Methanol (M85) = 100

5) Which alternative fuel has the most diversity to date for types of vehicles?

6) Rank the all the fuels on the chart by their energy content from highest to lowest:

7) Gaging by the chart, what seems to be the safest fuel?

8) Do you have any way of gaging whether this chart was accurate or not? How would you go about finding out if it is true or not?
