    1. It's weird and useless 2. IT RUNS OUT OF BATTERIES!

    1. You say that like it's a bad thing. 2. Eventually, sure. It might be possible to rig a solar collector to it, if the cover has enough openings.

    It doesn't even have to have many openings you could put the solar panels on top of the man hole cover and feed the wires down one of the slots :)

    Runs out of batteries?

    You should make it power itself from the methane gas in the pipes!!

     Somehow, I can't understand what this thing actually does. What does it do? 

    it lets random people who find the grate talk to other random people at the other grate.

    oh lol. Thank you for answering a 1-year old question!

    don't try this in Boston because they will think that you are a terrorist and be all paranoid about everything and you will get arrested.
