    Andrew, you had me until the part where you mentioned me eating algae. Yucko. Hok-ptui!

    I was not suggesting eating the algae, but growing it for energy. Algae can be grown in plastic bags in the desert, so there is no displacement of conventional food agriculture, and algae grows far quicker than conventional crops, and results in 3 feedstocks, a plant residue/biomass, a vegetable oil and oxygen.
    interesting to know whether conventional biodiesel plants could accept the algal oil as a feedstock, to ensure corn goes to food. The paradox is that ‘the green credentials’ of corn are going to see more trees destroyed, and more people starving.
    Does anyone still believe in democracy. It really is just a legitimatised form of fascism. Tyranny of the majority, or minority, its still a tyranny, even if we all get a few token gestures here or there.

      I’m in total agreement about the potential of algal fuel, but that was definitely not under the purview of this particular infographic.

      And taking your point about “the green credentials of corn” one step further, I’m not sure it has any.

    There have been many claims about the level of net energy production from corn ethanol. It’s been stated here that it’s 1.3 times the input. This is still hotly debated. I’ve seen claims ranging from a negative to a positive energy balance, but have never been convinced that all of the inputs have been recognized. These inputs include everything from manufacturing the equipment that’s needed to grow, process, and transport the corn and all the other ingredients; includes the fuel, fertilizer, pesticides, and enzymes needed to grow and ferment the corn and distill the alcohol; and distributing the ethanol to all the gas pumps. There’s got to be some bean counters that could run those numbers.
