More "Miles Per Acre" From Bioelectricity Than Ethanol

CarnegieScience writes "Scientist calculate that, compared to ethanol used for internal combustion engines, bioelectricity used for battery-powered vehicles would deliver an average of 80% more miles of transportation per acre of crops, while also providing double the greenhouse gas offsets to mitigate climate change."

Food crops as energy was never a good idea.

[LordKazan]

Food crops as energy sources was never a good idea, we didn't breed them for their modern harvestable energy content, and even if we did we'd be offsetting fuel crops. Algal Oil is a MUCH better biofuel solution as it can be build anywhere you have the following things:

A) Land [cheaper the better]
B) Source of Water [doesn't neccesarily need to be fresh or particularly clean, in fact fertilizer polluted water might even be a good thing]
C) Source of Carbon Dioxide [clean CO2 .. so cannot pull it straight from the air, have to filter it.. but pretty much everywhere]
D) Sunlight

And it already works, we have "pilot plants" already cranking it out.

Don't have to offset prime forest or prime agricultural - vast stretches of the semidesert southwest would be usuable.

Re:Units?

Miles per acre? What's that in rods per hogsheads?

Miles per acre ca't be converted into rods per hogshead. However, you may find the following conversions useful:
1 mile per acre is exactly 80 rods per rood.
1 mile per gallon (US) is exactly 63 furlongs per firkin (US)
Anything else you need can be computed from information at http://www.unc.edu/~rowlett/units/index.html
