[sci.electronics] Need Help!!!

engage@uokmax.ecn.uoknor.edu (Eric Neal Gage) (09/19/90)

     I am working on a project at the University of Oklahoma.  I need input
and this seems to be an efficient method to hear from people who know a
little more about electronics than I do (I'm an ME).  We are developing a
portable, 100W remote power system that couples wind power and photovoltaics.
If you can spare a few moments, please answer the following questions...
      
     1.  What can a 100W system be used for? (camping, military, etc.)
     2.  Would you recommend 12V or 24V system?  Why?
     3.  What would you consider to be maximum allowable weight?  Why?
     4.  Do you think there is a market for such a device?   

     Even if you aren't going to answer, thanks in advance for reading this
far.

Many telephonre systems have remote stations. 100W would be more
than adequare to drive subscriber multiplexers from remote
communities. Typical products would be
called SLC96 SLC96 mux's or newer TR303 mux's. There are a
host of similar products for remote sites from many
many manufactureres.

For telephony a 24V or 48V system would be desirable. The higher
potentials can be more efficently used to derive other voltages
required in the box. The 48 or 24V can also be use  to power
the station equipment (telephone sets etc).

There is a market today in the telephone market for remote
unattended devices. I've seen a lot of articles and
ad's for photovoltaic systems.
