The heat on the tube and the introduction of fans to keep people more comfortable was a little news blip yesterday. Annie had of course covered it a few weeks ago and I meant to comment at the time, but y’know… didn’t.
The issue that doesn’t seem to have come up at all is how much the temperature on the tube is currently being raised by the new batch of illuminated advertising pitches. I might try to find one of those flat thermometers to see just what the surface temperature is, but in the meantime just laying my hand on one (or my back, actually, when busking) proves to me that it’s quite a lot warmer than a paper poster :) This goes for the animated doodads that line several escalators.
So how many of these screens are there now? I am not a physicist, so does anyone want to help me work out the effect a single screen might have on the ambient temperature? What is the cumulative effect of all the screens in one station, how about across the 24 stations that are getting them? And are CBS Outdoor, who are responsible for their installation, made any effort to counter the effects? Wouldn’t it be a good idea to be shouting about this if they were? And I’m not a green extremist, but what effect have these screens had on the tube’s carbon footprint as a whole – how much electricity is being used to run them?
