Here is a circuit that can detect the presence of a radio frequency (RF) signal. If it is close to RF-emitting devices such as a television set or a computer, it shows a high reading in the VU meter, giving us an idea about the intensity of RF radiation in the room. High-intensity RF radiation from mobile phone towers in the vicinity is considered to be harmful by most.

that sod farm debate is a tricky one.  there are no trees to cut and the site is level and ready for panels. there must be a reason the sod farm is not profitable or seen as less so than a PV array.  maybe the soil is depleted after the years?  (the fertilizer supplier will not be happy.) one point to remember is the relatively low impact that the PV support structures have on the land once they are installed and how easily they can be removed afterwards.  the shade provided is a plus in a lot of locations. i bet it will make the groundhogs happy on the sod farm who've been getting run off all this time.

Infrastructure / energy use efficiency  - 
 
 
Electromechanical energy meters have been the standard for metering the electricity since billing began. But these are now being gradually replaced by Digital Signal Processor (DSP)-based energy meters, or Kilowatt-hour (kWh) meter. More accurate energy measurement and additional features are in fact accelerating the adoption of DSP-based meters. Their additional features include power quality monitoring, re-cording of Current/Voltage peaks and voltage sags, registering of digitized waveforms for analysis, and monitoring of active and reactive power and power factor information. Here's an energy meter using Ana-log Devices' ADE7757 chip for single-phase, 2-wire (phase and neutral) systems used in households. IC ADE7757 is a low-cost, single-chip solution for electrical energy measurement.

so many old systems being thrown away that these various distros will run on.
just go to the electronics reclaim center and pick one.

Energy storage (heat storage, batteries, fuel cells, etc.)  - 
 
 
Batteries are the marathon runners of energy storage; ultracapacitors are the sprinters. What do you think about this hybrid energy storage system, which combines both?
http://www.engineering.com/ElectronicsDesign/ElectronicsDesignArticles/ArticleID/12740/Hybrid-Energy-Storage-System-Combines-Ultracapacitors-and-Batteries.aspx

Batteries hold more energy, but ultracapacitors have quicker response times. Duke Energy uses a hybrid to get the best of both worlds.
