Work is defined as force x distance.
You can push forever on wall and you have done no work unless the wall moved.
Stoping time sounds cool enough, but your still at the mercy of linear reality, you still have to get were you are going and you are the only thing not subject to the laws of our time space continuum.
Now teleportation and the idea of moving through almost limitless energy to your destination is simply a matter of infinite energy x distance.
But if your going to play with limitless energy, by FAR the coolest things is energy to matter coalescence.
Einstein told us that E is = to mc^2 so we know that we can reverse the process and take energy back into matter.
The power I'd want is matter coalescence. You'd be tapped into unlimited power. You could created anything. You could even bend the laws of physics if you want.
In the end, id have the power to even make more powers if i wanted, all based on science.
Suck it Geoff.
