• WiTricity described by MIT's Institute For Soldier Nanotechnologies
• IEEE C95.1-1991 IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz -Description
• Ofcom's Guide to the Use of Radio Transmitters and the Law
  

Human Active Energy

• FreePlay's Wind-Up Radios
• FreePlay's Wind-Up Mobile Phone Charger - "FreeCharge"
• US Patent #5630155 - Portable Computer System with Mechanism for Accumalating Mechanical Energy for Powering the System
  

General Energy Harvesting

• An excellent chapter (pdf) from Christian Piaguet's book Low-Power Electronics Design by Thad Starner and Joseph Paradiso
