Kinda like just plain old gas aka rec. fuel. Get a petition together to make it more readily available and I will sign. I burn it in my 64 Dodge, three motorcycles, all my lawn equipment, and four outboards.

Anything would be better than ethanol. Done
Biosynthesis of Isobutanol
Higher-chain alcohols have energy densities close to gasoline, are not as volatile or corrosive as ethanol, and do not readily absorb water. Furthermore, branched-chain alcohols, such as isobutanol, have higher-octane numbers, resulting in less knocking in engines. Although produced naturally during the fermentation of carbohydrates and may also be a byproduct of the decay process of organic matter, Isobutanol or C5 alcohols have never been produced from a renewable source with yields high enough to make them viable as a gasoline substitute before the 2008 Nature article that produced over 20g/L isobutanol from glucose in E.coli.[6]
To modify an organism to produce these compounds usually results in toxicity in the cell. This difficulty was bypassed by leveraging the native metabolic networks in E. coli but altered its intracellular chemistry using genetic engineering to produce these alcohols. Key pathways in E. coli were modified to produce several higher-chain alcohols from glucose, including isobutanol, 1-butanol, 2-methyl-1-butanol, 3-methyl-1-butanol, and 2-phenylethanol. This strategy exploits the E. coli host's highly active amino acid biosynthetic pathway by shifting part of it to alcohol production. It is proposed that these unusual alcohols can be produced as efficiently as the biosynthesis of ethanol.[6]

Juan, are you a Chem E or did copy and paste that? Very impressive.

I wish they would test stuff in a limited study before assuming it's the best thing ever. I'd like to know more about how isobutanol affects things like fuel bulbs and gaskets that weren't designed for it's introduction. I'll agree that it will absorb less water than ethanol, but that's not the only issue...

Is Biobutanol the same stuff or just similar ?

As long as it doesn't have an affinity for water, it's an improvement both from an ecological and marine operational viewpoint.

I'm assuming biobutanol is the same fuel, only derived from plants. If they said bio Isobutanol then it would be the same chemistry. It's possible that it could be N-butanol, but I doubt it.
