That's just the solid part of the coal plant waste Morris. Don't forget the fly
ash and the various poison vapors that are released into the atmosphere. And
then there is the CO2... Statistically, it can be shown that coal plants kill
people, lots of people. Public deaths caused by nuclear power are insignificant
compared to those from coal. It makes no sense to discuss the safety of nuclear
energy without contrasting it with the public danger of NOT using nuclear power.
Here .http://www.ecomall.com/greenshopping/cleanair.htm is a slightly hysterical
article about coal plant pollution that nevertheless frames the issues and
points to some research papers.

approach the energy challenge from a different direction...
It's fairly easy to conduct a debate in terms of the advantages and
problems associated with various fuels. It might be productive at some
point to ask ourselves what we most hope for the world in the coming
century and millennium.
When I did that I found myself drawing a distinction between "fueled"
energy sources and "non-fueled" energy sources - and that's a lot of
what has motivated my interest in point-of-use solar energy. I don't see
it as a cure-all, but rather as something that leaves the door open for
future generations to pursue their own visions and hopes.
Yes - though, as mentioned above, I'm inclined to a broader perspective
and frame the entire picture somewhat differently...

They charge you to haul the crushed silicate slag away:
I bought one bag directly from the power plant. It cuts fast and well
on its first pass through the sandblasting gun but breaks down
quickly. So I switched to sand from the side of the road, filtered
through window screen.
