I think combined fusion/fission options are the clear choice for the future. (Also, yes, that is what the H-bomb does, and no, that is not what the sun does.)
Here's how combined fusion/fission plants would theoretically work:
A fusion reaction is used to create a large quantity of high-energy neutrons. These high-energy neutrons are then used to cause fission in an otherwise subcritical fission assembly with extremely low enrichment fuel. 'Natural' uranium (U-238) is fissionable, which means that it can undergo fission in the presence of /high energy/ neutrons.

Fusion power is actually already above break even. There are a lot more practical engineering problems with fusion power before that means anything, though. Most of these problems have to do with materials science: Plasma is incredibly difficult to contain, and it's very difficult to design a cooling system that could work sustainably. Without a cooling system, there is no way to make use of the heat generated in fusion.

This still conveys a lot of information.
Engineering is more male-heavy than lawyering.

But noscript says that it's not blocking anything on my search results pages. Does google detect my addons and remove the redirects if I might be blocking them?

I have never experienced this behavior in google, but would be very annoyed if I had.
My question is: Why haven't I ever experienced this? I use firefox with adblock (with a very limited filter - nothing on google is blocked) and noscript (nothing on google is blocked).
My other addons have no reason to alter google's search page.
