What can I say – I admire Borschberg’s courage at attempting such a difficult feat. But his failed attempt to fly to Hawaii was surely a perfect metaphor for what is wrong with renewables. Borschberg’s plane can’t carry cargo or passengers, it can barely carry its own weight. It would have been impossible to construct without high tech petroleum based plastics. And when the weather turned against him, Borschberg’s ingenuity and courage was helpless to overcome the inherent shortcomings of renewable energy.
