Re: Carbon based fuel

All repeat all fuel is carbon based.
The difference between Bio and Petro is that CO2 released by burning Bio was recently removed from the atmosphere so re-releasing it does not affect the overall levels of atmospereic CO2. Petro releases CO2 that was removed from the atmosphere several eons ago so it does increase atmospheric levels of CO2.

The statement that you must burn dino based fuels to produce Bio is false, why not use Bio fuels to produce it. After the first cycle it is a neutral situation.

Bio fuels can be produced from crops that are essentially weeds ie camelina BD and switchgrass for ethanol, thus greatly reducing the work done with farm equipment to produce the crop. They are esentially broadcast and harvest crops tillage is unnecessary.
There is a lot of effort being placed on developing algae that produces oil. This is promising because yields are very high per acre. I believe cities could build algae ponds and use treated waste water to fill them thus turning waste water treatment into a revenue source instead of an expense.
The next best yeild per acre crop is palm nut oil. There are large tracts of unused desert in the south west, where palms grow well, that are not suitable for growing other crops.
When you add the different oil source crops together and realize that they can utilize land not currently used for food production that arguement goes away also.
