Yes, it is possible to use a grapefruit as a battery, the lightbulb has to be fairly low wattage though.
Acid fruits do this. Lemons, oranges, grapefruit come to mind immediately.
The cost of a grapefruit in 2008 is apparently unknown, but estimated somewhere in the range of $100,000 to 1 million dollars a grapefruit seed.
there is pretty much no acidity in a grapefruit...it is only bitterness.
