Assuming that there are no accidents, what is the downside to nuclear power generation? How much toxic waste does a nuclear power plant generate over its lifetime?

Would we be saving the atmosphere at the peril of the terrasphere? (I think that I just coined that term, but feel free to use it in dissertations and such.)

When I hear George Bush promoting nuclear power, red flags automatically go up.

It is inside a glass sphere with a glass tube that comes down outside the sphere and goes up to the center of the sphere. On the tip of the tubes top a cone sits on it with 4 arms that have one card on it. One side of the card is dark colored and the other side is white. When you but this thing in the sun it spins slowly. Why?

-My only guess is the heat from the sun is held on the dark side of the card and some how releases energy to move.

Would it fracture from within? Would it crumble from the top, or crumble from the bottom? Would it possibly suffer a different consequence? What are the chances that it would remain standing?

I use 4 mortar like cannons to propel a projectile. Attached to the projectile is a net. The net is shot over birds to trap and relocate them. The motive force for the projectiles is compressed air at 120psi. The air is discharged into the mortar barrels simultaneously. I've been told that if I lengthen the barrel, I will be able to obtain greater projectile velocity. What are the parameters that would control the velocity? How can I calculate the optimal barrel length? I'm thinking with a short barrel, a lot of the compressed air escapes from the end of the barrel as the projectile leaves. Thus energy wasted. It seems like the optimal barrel length would be when the compressed air pressure has dropped to atmospheric pressure at the point at which the projectile exits the barrel. Assume a large tank feeds each mortar barrel and there is a negligible drop in pressure during the discharge. An electronically controlled orifice of diameter D opens for duration T.

There's really only 2 choices you have either to believe in God or not.

1: The universe is uncaused and there are multiple universes that caused the universe accept what caused the mutiple universes???

2. Or an infinite uncaused being or force caused the universe.

Which makes sence?
