too late for me--but someday!

In the team's experiments they were able to produce 64 nanowatts per square metre (10.8 square feet) of power

A nanowatt is One thousand millionth (10-9) of a watt.

I'm impressed they were able to measure that. It's a completely useless amount, and takes up a large footprint. "Neat", but they'd be better off putting lightning bugs in a jar. :p
