Is building a data marketplace same as building a plane or inventing the telephone? David Knight describes the big void above the IoT stack and what he envisions as a big exchange in the sky that would interconnect all the sensors and facilitate transfer of data in a curated way.   David is a self-describe serial entrepreneur, angel investor, filmmaker and ardent supporter of STEM education. He founded, co-founded and held leadership roles in tech companies with exits including two IPOs, two M&A buyouts, and two post-bubble meltdowns. He is also a trustee of the California Science Center Foundation involved in building a large new Air & Space center for the Western U.S. Terbine is building the first large-scale digital marketplace for sensor data – things like vehicle counters, sound levels, powerline loading, carbon emissions and crop density. Terbine’s highly curated data trading/exchange system makes sensor information accessible, actionable, and trustworthy for applications across a broad range of industries. The company's initial focus is on Intelligent Transportation and Smart Cities. http://terbine.com/video.html   IoT ONE is an online platform devoted to accelerating adoption of Industrial Internet solutions.
