It’s a fusion reactor the Bane gets his hands on. I’m going to assume he isn’t looking to provide Gotham with an alternative clean energy source.
Here’s a bit on fusion reactors Comic Book Movie grabbed from How Stuff Works:
Fusion reactors have been getting a lot of press recently because they offer some major advantages over other power sources. They will use abundant sources of fuel, they will not leak radiation above normal background levels and they will produce less radioactive waste than current fission reactors.
Nobody has put the technology into practice yet, but working reactors aren’t actually that far off. Fusion reactors are now in experimental stages at several laboratories in the United States and around the world
You can catch TDKR in theatres July 20th.
