Your Questions About Wind Turbines For Home Use
Thomas asks…
Can i use a Desktop PC UPS in a small wind turbine system?
Iam a mechanical engineer and i would like to make a small wind turbine for my home in Chennai. i can easily make the turbine part and couple it with a DCPM motor. it is difficult for me in the electronics side. In any way, is it possible to use my desk top PC UPS for storing and reusing the power generated?

Hi.. I am an electrical engineer!!!
Yeah its is possible till u meet some requirements
1. From the UPS.. The output is AC.. And the input of the DCPM Motor is DC.. So u need to convert this into DC with a converter called Rectifier.. I would recommend a ful wave recitifier..
AC converted should be of the frequency of 50Hz!!… This is very important!!
2. The current and voltage rating of the wind turbine should meet the rating of the UPS..
The rating of a standard household domestic purpose UPS would be 240V, 5A.
(Voltage is constant and the maximum current is 5A)
3. If the rating of the turbine is more than 240V.. Please do not connect to the turbine.. It causes overload on UPS!!
Hope this might help
Maria asks…
How efficient are small wind turbines for homes (not wind farms) in percent efficiency? Which small is a buy?
Germany has a program (“A Million Points of Light”) to install wind turbines in homes. Finland has small vertical axis wind turbines going up in cottages, on chimneys.
Which is the best design for a home-power installation? What are the efficiencies of the different blade designs?
Anybody know anything about the ‘bent-prop’ design, like this one?

Does the chimney need to be reinforced?
How high does the wind turbine have to be, over the tallest house in the neighborhood?

Wind is free so it does not make sense to talk about efficiency.
Robert h mentioned NOISE, that should be your primary concern.
Remember wind does not blow all the time, so, you will need a battery bank, and an inverter, to turn it into AC power. This is all rather complicated to run, if you do not have a technical bend.
Lookup some suppliers and ask them to explain it to you.
