What to do with NiMh batteries?

Ok guys and gals.. I need you to put your heads together and help me out

I am in possession of thousands of NiMh cells

They are for all different cars

Prius
Camrhighlander
Accord
Civic
Insight
Escape
Focus
Mariner
Vue

They are coming out my ears

99% are good cells and hold a charge

We are getting them faster than we can use it up for repairing customer cars

Any ideas who else might need them?

Some ideas are using in a solar application. I saw this video from a collaborative effort between Toyota and Yellowstone Park which was pretty cool. If you have other ideas post them up here
