biomass environmentally safe ??
Totally agree, it is fucked up, even if we had sustainable forests next to the plants and used the wood from there ... still better than nuclear, though ... because CO2 levels can be reduced to acceptable levels in time-frames several magnitudes (couple centuries vs millions of years) below nuclear waste disposal.
There are much better alternatives, though, wind, solar, and geo-thermal (admittedly, all still need substantial research and development). The thing is, the energy source is unlimited and free, when the sun stops shining, humanity will have already been long gone ;-).
PS10 solar power plant is very interesting, I think. We need to increase efficiency and get the costs down ... that was the first of a series.
