Can you harvest electricity from a jellyfish?

Yes, a jellyfish is comprised of Nematocyst capsule and tenticles, the sting from a Jellyfish is not electricity. It is a toxin produced in the Nematocyst. The only way to harvest electricity from a Jellyfish would be from the small amount of heat that is produced from the living organism. An enormous Jellyfish farm would be required in order to produce enough heat to move a turbine.

So nope, you haven't figured out the worlds energy crisis.....

They are useless little fu*?kers!!
