We all have more abundant resources than most of us realize.
I realize that this branch of research is just beginning, but we all have un-utilized energy sources.
Yard clippings, leaves, pooper-scooper material! Even our septic tanks!

All of this and more could be used as energy resources.

This is mostly out of our reach 'at present', but while reading some of the articles here at greentech I was once again reminded that what is economically or fiscally impossible today doesn't apply for tomorrow.

We can do this if we apply ourselves. We aren't trilobites or T-rex. Whatever we we put our determination behind, we will learn a lot more than we bargained for.

Only a few years ago reports were coming out stating that "bio diesels" and ethanol (fuel production) were not practical because of cost analysis results.
Today we see them looming on the horizon and even closer.

One day I asked my (late) dad, when he expressed disbelief about being able to see the ISS from earth
"Hey dad, when you were growing up, did you ever think men would land on the moon"?
His answer? "No"

My point behind all of this crap is that we can determine our own direction.
We don't need cost analysis behind everything we do.
Sometimes we just do things because we want to and it turns out for the best, even if it takes a while.
