OK, what's a good black swan?

If you know comment about it here...
I have a little idea...

A new bio-fuel made from plastic waste fished out of the oceans... provides clean burning fuel for a billion cars.  

Solar panels on business rooftops provide over 50 percent of US consumption requirements.

Another black swan could be...

"An alien visitation disproves all religious beliefs". Thus proving there really is no dog at the wheel.
