If my dimensional analysis is right, you could store 12 kW*hours by  
lifting a mere 500,000 kg about 10 meters. Just start storing your old  
UPS batteries (or dead batteries from someone else's battery-based  
tornado backup) in the attic for use as a working mass. Then when the  
tornado triggers a structural failure in the building containing the  
main data store -- the very event you are protecting against -- your  
gravity-based generator is automatically activated.
