Calculated Spontaneity is 80% Efficient

Found a pretty astonishing article out of Idaho National Laboratories. Apparently, sometime last year, they developed an inexpensive solar 'panel' - really a sheet - that is around 80% efficient. The technology relies on collecting IR waves. Unfortunately, more work has to be done to convert the energy that they have collected into usable power, but this is still a massive leap forward in solar technology... kind of surprised it wasn't mentioned in class.
