Green escalators...

I'm at a conference watching empty escalators roll constantly and I'm thinking what an incredible energy waste. Ironically, the first speaker of the morning touted the "green-ness" of the Raleigh Convention Center.

My first inclination was that escalators should come with sensors that would detect an approaching person and start it rolling and continue rolling until they are detected to have left the disembarking area.

After further consideration, given that we have an obesity epidemic accompanying our energy challenges, the best thing for our energy and our health would be to just turn them off entirely...
