September is here, and TIDES' 4th Annual Fall Demo is just one month away.  If you'd like to participate in this exciting event, now is the time to act. See details below.    
This month we are beginning a new feature, highlighting organizations that work in humanitarian assistance and disaster relief.  Also in this edition is Larry Wentz' Haiti paper, a must read for anyone wanting to know more about the ICT sector after the earthquake.  Finally, Lin Wells will be on the EmeraldPlanet TV program tentatively scheduled for Sunday, September 26th, see details below.

Feature:  SunNight Solar
By Mark Bent
Conventional recommendations for providing emergency lighting have not changed much in recent years - buy a flashlight and extra batteries and hope the cavalry arrives and the power comes on before the batteries run out.  While this advice is a boon for the battery manufacturers, recent advances in three separate technologies offer a less costly and more reliable answer to illuminating the night in post disaster recovery operations.  
     Solar or photovoltaic panels, rechargeable batteries and light emitting diodes (LEDs) have all shared the following in recent years - they have gotten much better in reliability and performance while simultaneously become much cheaper. These solar powered products showed immediate value after the devastating Haiti earthquake of January 2010.   There was an immediate call for lighting by the World Bank, non-governmental organizations and the US government.  USAID estimates that one light impacts ten people each night in the Port-au-Prince area.  At a wholesale price of just over $10.00, the cost to benefit impact ratio is quite attractive.
     The operation of the products is simple - place in the sun during the day, the solar cell generates electricity; the power is routed via a circuit board to rechargeable batteries where the energy is stored.  The energy is then released at night, powering the LEDs.  The circuit board is an energy management device - too much sun, resulting in too much electricity being generated, could overcharge the batteries.  Full discharge of the batteries is also not good for long term use and power spikes to the LEDs could destroy them.  Many products use off the shelf rechargeable AA batteries, which can also be removed from the device and used for other purposes - powering a radio or small GPS.
     In one day, sufficient energy is collected to provide illumination for four to six hours each night.  Some products have high/medium/low settings which allow for illumination all night long.  The AA batteries are rated on charge/discharge cycles, normally between 750 to 1000 cycles.
     In the developed world where power, and illumination, is taken for granted, these products should be in every family's home emergency kit. In the developing world, where close to two billion people remain off the grid, lighting, or the lack thereof, impacts health, education, safety, security, economics of the end user, agricultural productivity, the environment and overall quality of life.
