Last minute repairs in Marathonas

Last weekend we went to Spithari.org in Marathonas to put up one of the two wind turbines that we will be going to see on Friday. Two of the coils had managed to short themselves out, so Kostas put on his scrubs and did some keyhole surgery to put it right.

Unfortunately we got soaked in torrential rain putting the turbine back up and to make things even worse, when we flipped the brake switch, nothing happened. You win some, you lose some.

One week to go!

With just a week to go until WEAthens2014 kicks off, preparations are well and truly underway here in Athens:

The video above shows the rotor of a 1.2m Piggott turbine mounted onto a variable speed drive to control rpm. A torque meter is mounted in line with the rotor to measure mechanical power via rpm and torque. On Thursday morning, NTUA students will take you through the experimental procedure used to measure the Cp-TSR curves that characterise a wind turbine rotor’s performance.

The working section of the wind tunnel is so big, you could park your car in there!
