Last week a Swiss start-up around the concept of Hyperloops emerged from the research stage into testing mode, saying it eventually plans a transport system from Zurich to Geneva which would take 15 minutes – a journey of 139 miles. Short airplane rides or long distance train rides seem to be best suited to the Hyperloop concept of a hollow, low air pressure tube, having pods accelerated within them, to speeds approaching 500 miles an hour. So little power is required for one of these systems that painting solar around the tube would provide more than enough energy to ruin the system, which could be a net contributor to the grid – very different from today’s trains.
