A Heated Runway?

Sign in to follow this  


Last night while I was watching the news, one of the featured stories was about a heated runway at Des Moines International Airport in Iowa. The runway was being kept at 62 degrees Fahrenheit so any snow that landed on the strip of the heated runway would melt very quickly.

To do this, researchers at Iowa State University embedded electrodes into the concrete and powered the electrodes. When they turned on the electricity the electrodes began to heat up the concrete around them, which would make the snow on top melt. The even cooler part is that although an entire runway costs about 200 million dollars to heat, it is projected to save passengers, airlines, and airports 273 million per heated runway. Useful and money well spent!

Really cool topic. There are prototypes of smart roads which actually display useful information to drivers. I can only see this technology growing in the future.

I read something on this before and it would be very interesting if there was a way to implement the technology into all of the roads throughout the country!
