I have bad feeling about prairie grasses.
Nothing will be returned to the soil and it will be the same old story.
Such fascination with new sources for old habits.
Like in Geoff's video except we are the maggots.
As you might tell, I am very skeptical of all this.
It is not PERMACULTURE. I do not believe you can renew what you burn.
The Sun is free, clean and limitless. The wind is free, ample and clean.
Save the carbon fuels for critical needs and transitioning.
Must we burn everything we find? This just feels wrong?

>From the article, "Tilman's research now shows that
the opposite will be true when it comes to growing
crops for fuel. He and his research team discovered
that land planted with a highly diverse mix of prairie
grasses and plants will actually produce more than
twice the bioenergy of the same land planted with any
single species, including Corn.
"We were getting as much and in fact, in some
conversion processes, more energy per acre on marginal
land than we get with current corn production," Tilman
explained.
Perhaps even more promising are the findings
concerning greenhouse gasses. Native prairie grasses
and plants appear to drastically reduce greenhouse
gasses, findings recently published in the journal
"Science."
By capturing airborne carbon dioxide and returning it
to the soil, prairie grass biofuels are essentially
carbon negative."
He goes onto say, even if you used all of the corn
currently in production the ethanol would be less than
15% of what we consume ....
Food for thought......
