- put on a screensaver of art that you like
- close the doors of a cabinet around it
- roll down a screen in front of it
- roll it into a closet
That's a great idea, although I wonder what the typical power consumption is of a big screen TV and how much it would cost to leave it on 16 hrs/day.
A Tesla model S can get 240 wh/km, so the energy use of the display would power an electric car for 10 km. so for a year then it would be the equivalent of moving an electric car 3650 km. I don't drive that much, but it is actually about half of my yearly driving averaged over the last 10 years. Personally I rather turn that screen off and power my next car with it.
Edit: just saw you said 16 hours. Well you can do the math. :)
