1. Benefits, Examples, and Applicable Fields of Energy Harvesting

2. What is Energy harvesting?
Energy Harvesting is a way to collect and use energy from sources other than fossil fuels, like the solar, wind, thermal, vibration, and other biological sources. Energy Harvesting allows the ability to tap into these alternative energy sources and provide electricity for our small electronics, or supply power grids. 
Most known energy harvesters:
Solar Panels
Wind Generators
Huge Addition to the Power Grid
Still more out there
Alternate sources:
Alternative energy sources are called ambient energy
Ultra Low Power MCU's (microcontroller families) convert ambient energy into useful energy. 

3. The crystal radio Introduced in 1904 Was popular Components:
Wire for antenna
Coiled copper wire for adjustment
Capacitor
Crystal Detector* made from a crystalline material like galena (diode)
Earphones 
Powered by the waves picked up by antenna

4. Applicable fields Built infrastructure and systems
Buildings, transportation (public, commercial, and personal), and consumables
Ecosystem Services and the Environment
Examining certain habitats, species, watersheds, and global climate change
Sociotechnical Systems
 Society, organizations, and people

5. Emerging technologies
Na-TECC: 
Uses expansion of sodium and solar heat to directly generate electricity
Distributed energy applications, such as powering your house
Flexible Generators (TEG)'s:
Solid-state devices that convert heat to electricity made from attractive polymers
Generates small amount of electricity, but could be sprayed anywhere
Fuel converted from sky:
Uses solar energy to reverse the combustion process to make synthesis gas which can be converted into kerosene, gasoline, and fuels like them.
Instead of using fossil fuels, uses byproducts of combustion and energized by  the sun to create these fuels.
Graphene Supercaps:
Graphene-based supercapacitors that could replace batteries
Current low energy density, but graphene based supercaps offer much greater energy dense devices that will provide high power and longevity.
