Good catch on date!

I didn't understand because there's So Much Energy Harvest technology that running a chip on a solar cell (2 sq in?) seemed ridiculously easy to me.

I didn't read much further into the article thinking there was a mistake Or something unique. I don't know what size chip can boot/work with Just RF harvest but there's many.
