What is it? Some people dream of riches. Others dream of world peace. Others still dream of powering a skateboard using a cordless drill. That was the dream of Tony Ward, inventor of the Kranx Powerstik – and now he wants to make it a reality. When’s it due? September 2015. Why are we excited? The Powerstik is to skateboards what the hamster is to the MacFormat office computers: a source of power. It’s the kind of insane invention that we all love, where someone has clearly taken their two favourite things and cheerfully mashed them together. It’s a labour of mechanical, drill-based love, and we can’t imagine where it might lead.
