[RE-wrenches] Up for a 1-Line Riddle?

[Andrew Truitt]

Ahh yes, the old "combine strings before landing on a fused DC input
terminal" trick.  Sure to blow the fuse the first sunny day.  This is why
SMA created their fuse-bypass DC input terminal.  I take it the installer
was not aware of this...

"Don't get me wrong: I love nuclear energy! It's just that I prefer fusion
to fission. And it just so happens that there's an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it's wireless!"

~William McDonough
