Simple Computer Animation

I'm a university student working on a design project, and need to produce a simple animation of what a working design of our idea would look like. Basically, we want to have a small animation of a person placing trash into an incinerator (basically just a big grey box), and the incinerator would produce steam as it burned the trash. This steam would turn a turbine that would generate electricity. This electricity would be stored into another big grey box (a generator). The waste from the steam would then be placed into a hazardous waste container to be disposed of, and the remains of whatever was burned would be sorted through and anything that could be recycled, would. So some sort of simple animation showing that would be good. After the electricity from the turbine is stored, the generator would be connected to an apartment building, which would use the electricity collected, as required. Maybe at the end of the video, it would show people who live in the building happy because they had saved money. The animation should be very basic, with little detail other than what I described. It's a bit urgent, as I need in done within 24 hours if at all possible. Thank you!
