Every energy source is energy harvesting at some level (even oil, gas, hydro, coal, geothermal, wind, and solar). It seems to me that the emerging Energy Harvesting Market should exclude those sources in the market analysis and only include the harvesting of "incidental" energy (vibration, local temperature gradients, ambient radio waves). Otherwise the statistics will be "double dipping" energy sources.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
