Silver is the new green

The title might be a bit of an overstatement but I am mightily impressed by the guys from Altaeros from Massachusetts. For the windsurfers and kitesurfers amongst us we all know what a boost you get from flying your sail that much higher in the air. And the way Altaeros has delivered this is nothing short of amazing. What a beautiful and innovative way of delivering renewable energy. I am sure that a lot of wider impact assessments still have to be done before we can hail it as a perfect step forward but the signs are good.
