Comments on: Cellulosic ethanol plant to open next year

Range Fuels says it will be the first to produce the alternative fuel on a commercial scale.

Waste as a feedstock, good...

But if it turns out that the economics of using purpose-grown
materials for cellulosic ethanol are good, there would be nothing to
prevent food crops from being displaced until we have a balance
where both driving and eating are financially painful. Not enough
land to do both at a reasonable cost with this technology.

Waste? Is there really such a thing?

The trouble with cellulosic ehtanol is that the type of plant and
animal waste used for these plants would have been composted
and returned to the soil. Whether food crops or cellulosic waste,
making ethanol turns out to be mining top soil. If we don't return
the cellulosic material to compost, our farmland will be dead in a
century-- the great plains will be turned into a desert wasteland of
soil with no nutrients. Everybody needs to wake up to how
dangerous this is!

Handn't looked at it that way

The same comment would apply to all kinds of crops, wouldn't it?
Perhaps the waste products from the ethanol plants could be put
back onto the land. On the other hand, I think we should not
depend on ethanol being more than a niche product anyway. Not
enough land for much more.

OK, this may not be a good solution. What is?

Your point about "waste" being a meaningless term in the
environment is well taken. One man's trash is another
(microbe's) treasure. Nevertheless... and I mean this without
sarcasm... if the answer isn't:

* fossil fuels (due to carbon emissions),
* cellulistic ethanol (for the reasons you raise),
* hydrogen (because the required electricity is likely a problem),
* windmills (killing migratory birds),
* dams (killing salmon and snail darters),
* nuclear (waste radiation issues),
* solar (pesky nighttime and dirty batteries)

...then what is the answer to our energy requirements? Is there
one? Every solution has issues, it seems, so should we discount
all of them because of these issues? Is this an example of
"perfect is the enemy of good enough"?

Our farmers have figured out

that tricky crop rotation thingy. They've known about it for centuries. Your concerns are unwarrented. Farmers today make decisions of what they are going to grow based on what he believes will grow in what field. He knows what crops will produce the most money but he also knows that he can't deplete the soil each season.

76 Million Dollar Grant

The damn plant only costs 150 Million, and that pays for 50.6 percent of it...

What am I doing wrong???

What you're doing wrong

You are not a well-heeled investor seeking corporate welfare! Let's
cut single parents off of welfare and give $76M to wealthy
investors, they really need a hand up from the government.
