black body cooling on venus

a personal question, considering the incredible heat you find on venus, could a narrow band black body thermal radiator similar to that being developed at Stanford (other people are probably doing the research but, this is the team I am both aware of and find when I do a quick search), be developed for the atmosphere of venus.  On a planet with an incredibly thick atmosphere that holds onto heat harder than an action star hanging off of a helicopter in a movie, are there parts of the electro-magentic spectrum, that one could successfully dump heat into the void of space.

Nanny Bots

The nanny bot system first came about as an augment tool for UN forces overseeing wartorn regions, a true 3rd party overseer the network of quadcopters and cameras could not only observe and report on the actions of people but could learn patterns, over time limited non lethal tools were added to the repetaiore

all over the world company's and national institutions started to emulate the nanny bot system,
traffic stops started to eliminate patrol cars, while there might be a human operator on the otherside to talk to drivers, passengers, no one was risked

As time went on more police departments gave way to these systems

.....

turns out this is roughly the plot of robocop sans evil corporation plot line


tattlebots,(combo of tattle and paparrazzi) they follow you around, while following the local laws keeping an eye on individuals who might be up to something sketchy, their recordings can only be used when something bad happens, the vehicle gets damaged it sprays DNA barcodes all over the place
for the US an alternative/augment to low grade criminal monitoring tools
for abroad, following suspected millatants in a region
