[Concrete]

very good stuff I'm enjoying this

Duffman,
excellent points
my concern with nuclear is not truly technical, it is human
- you know the political crap that hamstrings progress
- the greed that might entice short cuts
- the incompetent and mistake prone humans that will run the system
- the short memory and lack of concern to properly care for long term waste
the stakes are higher with nuclear - but it is the same quality of humans

as for fuel reprocessing
I usually think of Hanford and think it might be best we don't
(Radioactivity is like a booger, it is hard to flick off, best to minimize contact )


Neil,
you are right - eventually all products have to be sustainable
this a very interesting topic for another thread
but all commodities will be scarce in the sustainable future
what is left, looks like biology - carbon cycle etc.

I do think Mr. McDonough left one important aspect of trees out of his speach
They Grow Back
and I could not understand his issue with a paper book - it seemed like a stunt
he printed his book in plastic? so it could end up in Pacific gyre?
instead of a product of the carbon cycle that can decay back into tree fodder
- is he serious?
I'm almost persuaded by James that this is propaganda (or a get rich scheme)

I personally use as much paper as I can
that way when it gets sent to a land fill - never to rot
I have successfully sequestered some dangerous carbon
just kidding

Wind, solar, nuclear, natural gas, biofuels, coal, oil.

Each has its positives and negatives.

We need to desist in trying to pick one winner. We need to get government out of the way of ALL OF THEM.

Dave,
I'll vote for you

and may the best solutions win!
