What type of engineering uses a lot of thermo?

[zachdr1]

I'm taking mechanical engineering thermodynamics right now and it's awesome. We just got into enthalpy and stuff like that and it's so interesting. It has me thinking that maybe I want to do something that has a lot of thermo or subjects that are similar.
