Our reactor actually burns nuclear waste as fuel. So not only is it safe and powerful, it solves an important issue: It actually reduces nuclear waste instead of creating. It’s the reactor of your dreams.
For relatively modest amounts of sulfur dioxide injected into the atmosphere, you could easily cool Earth by 1% or more, if you want.
Age can be wonderful for red wine, but not for spacecraft.

The depressing thing about battery technology is that it gets better, but it gets better slowly. There are a whole bunch of problems in materials science and chemistry that come in trying to make existing batteries better.
