The interaction between theory and careful experimentation has always strongly attracted me. I also like to work on the problem in front of me.
Orchardists around the world spend millions of dollars on expensive and labour-intensive ways to protect crops from frosts.<br><br>But engineer Rafael Guarga, having witnessed the devastation caused by frost to citrus fruit
crops in his own country, developed the Selective Inverted Sink system (SIS) and later patented the device.<br><br>A motorized fan sucks up the frost-forming air and expels it 100 metres above the fruit trees, dispersing
it into warmer layers of air. The SIS is used on crops grown across thousands of hectares on hundreds of farms from New Zealand to Spain. Guarga, the President of Frost Protection Corporation, believes it is likely that, with increasing
frost damage due to climate change, the SIS system will be installed to protect many more thousands of hectares in the next few years.
