A huge group of jellyfish clogged the cooling pipes at a nuclear power plant, forcing one of its units to shut down. After a couple days, the jellyfish had finally been cleared and the reactor ready to be restarted.

So next time you’re up on your roof giving your solar panels a gentle cleanse, feel secure in knowing that the only thing you have to worry about is some bird poop. And while the jellyfish situation is comical, having to shut down a nuclear reactor can be dangerous. So you’ll be breathing a little easier knowing that going solar means relying less on conventional energy.

Why is everyone looking at me? I was just exploring a cool looking pipe.
