Solar powered trash compactors

I never thought much of trash mashers, that wonderful device people used to put in their kitchens which magically turned forty pounds of garbage into a perfect square of forty pounds of garbage. They are pretty much gone now that people separate their garbage and recycle. Except at the San Diego wild animal park, where they are putting them throughout the park in a new, 21st century solar powered version.  i was was at the park over the weekend visiting and saw them in action.  Good Job! i’m happy to see solar applications in the market place.
