I had a 2.5V 5F supercap. I charged it for a while using a solar cell and 
then discharged it through a small motor. It ran the motor for about 30 
seconds befor it died to a crawl then stopped. I was very surprised by how 
long it ran. Look for projects on the net that use supercaps as power 
sources for small motor driven toys or bots.
