An interview with Powercast at the Energy Harvesting & Storage USA exhibition. Powercast is a designer and producer of embedded wireless power based on RF energy harvesting. Powercast’s technology enables remote charging of micro-power devices using controllable wireless power, over distance, between one or more sources and multiple receivers. Devices with Powercast components can be designed for battery-free or battery-recharge operation, thereby eliminating disposable batteries.

Interview with Witt Limited at Energy Harvesting & Storage USA. Witt Limited has created a scalable energy harvesting device called the WITT which captures energy from motion. Whilst there are numerous applications for the technology, Witt Limited are initially creating WITTs to power small vessels and navigational buoys from sea motion. This will be followed by a smaller WITT to generate power from human motion when the right development partners are identified. Future applications could extend to generating grid scale power from the ocean. For more information see http://www.witt-energy.com and http://www.IDTechEx.com
