Frank Binney is an interpretive writer and long time caver. I worked with him in the past to dream up and draw exhibits to be installed in the new National Cave & Karst Research Institute under construction in New Mexico.
The building will feature a Ground Source Heat Pump which exploits the fact that the constant temperature under ground — in a cave say – is an average of the summer/winter extremes above ground. So using some sort of exchange medium you can cool a building in summer and heat it in winter with a lot less energy.
Frank needed a drawing of a simple interpretive panel to explain to visitors how it works, bearing in mind that most people spend 45 seconds tops at each display in a visitors center or museum. (Advertisers have known this for years.)
Below is a series of sketches Tom prepared that led to the drawing at the bottom, which Frank sent to the client as part of his proposal for the exhibit.
