Wind turbines at the end of runways?
« on: December 04, 2015, 04:48:32 PM »
Just a thought - would it be possible to install wind turbines low down to the ground at the end of airport runways? I'm just thinking about when a plane takes off; when commercial jet engines power up to full thrust that's a lot of energy being released backwards. Perhaps we could somehow harness the jet blast? I guess the main concern would be safety.

Could you ever see this happening?

I had this exact same idea, and also came to the conclusion that safety might be an issue. Remember that only half the energy is being used to push the plane forward, with the rest being used to push air back.

In the corners of some runways I can see it being viable. The turbulence spreads far so you could harvest energy away from danger. It would take years of red rape though in all likelyhood.

I doubt this will ever happen. Building a windfarm close to an airport is already cause for planning rejection, due to radar interferences. Building one on the runway itself would never happen.

Surely having some sort of low Veritcal axis turbines wouldn't affect radar though, surely?
