How to make a concrete base for a wind turbine.
Kit for sale now- www.berezintechnologies.com blog -- http (more info) DIY vertical wind turbine of the Savonius style. Notable is that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy and the generator is a recycled automotive alternator with magnets added). Axle: 3 inch PVC piping from Home Depot Bearings: 5 inch lazy suzan from Lowes. Part 3 will cover connection to the battery bank with charge controller www.berezin.com (My Blog with more info and photos on this and will contain DXF drawings of the gears and other components which can be made manually or with CNC)
Wind Turbine setup. First turbine in Garissa Kenya. Off Grid system runs 12v DC lighting and 240V AC wall outlets. To buy these wind turbines in Africa contact: acewindenergy.com To buy these wind turbines in the United States, contact: oemwindpower.com
Savonius running at night in gusty winds. Base is expanded over previous version to make room for generator which will be mounted in a few days.
berezin.com for more information This is a preview of our new turbine. This turbine is still under development but is performing very well in initial tests. This turbine is much lighter and faster than previous turbines I've built. For one, it is a lift based turbine utilizing symmetrical airfoils rather than a drag based turbine such as the Savonius. This has both advantages and disadvantages. This turbine really goes, but the Savonius starts up easier in super light winds. The airfoils were designed using open source design software and fabricated with composite materials for light weight. This wind turbine also uses sealed bearings and requires no oiling or regular maintenance.
Here we put up a wind turbine from start to finish.
This vertical axis wind turbine uses a permanent magnetic bearing to support the vertical forces. Only small conventional bearings are needed to support the side forces. Next additions will be hall effect sensor to log rpm and PIC processor to record RPM, voltage and current and allow us to cross correlate with our weather station wind data which is being archived. This will allow us to determine whether design modifications help or hinder power output. Neodymium ring magnets (2" x 1/2") are used for the actual levitation. These same magnets are used in the alternator thus reducing the number of different parts needed to build the turbine. Small roller blade bearings are used to handle the side forces. berezintechnologies.com

My associate, Paul Gelling, populating the front panel of Collabworx/Sensyr Energy Monitoring AC Power Distribution and Network Hub which will be used as part of a smart building system in the Syracuse University Center of Excellence building located in downtown Syracuse, New York. The system will be used to monitor energy in a cubicle to analyze the way people use energy in an office situation. All eight outlets will be switchable over the Internet using an embedded controller with solid state relays. Total energy consumption will be monitored and logged, for the purpose of determining whether or not the smart building system can actually save energy when providing personal environmental monitoring and adjustments. Because this cabinet cover is not perfectly flat, it was a challenge to machine the text without making it too shallow or cutting completely through the box. We used one box as a test unit and finally found that a depth of 5/100ths worked well and set the zero point on the Z axis at the highest part of the lid.

Part 2 is now done and covers power generation: www.youtube.com Harness the wind for less than $100. DIY vertical wind turbine of the Savonius style. Notable is that this cost less than $100 in materials so far and that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy). Also, this turns well in a very light wind. Axle: 3 inch PVC piping from Home Depot Bearings: 5 inch lazy suzan from Lowes. Part 2 will cover power generation and connection to the battery bank.
more details at berezin.com This is my first attempt at a wind turbine. It is a lawn ornament at the moment (no power generation). I will follow this up with a video on construction details and power generation. Notable is that this cost less than $100 in materials so far and that the largest part of this turbine is recycled materials (the PVC drums previously held Balsamic Vinegar from Italy). Also, this was turning pretty well in a very light wind. Axle: 3 inch PVC piping from Home Depot Bearings: 5 inch lazy suzan from Lowes.

Analysis by Paul Gelling of an inexpensive grid tie inverter. This inverter will plug into a normal wall outlet and allow you to produce 110 V electricity from a wind turbine or solar panel and lower your electric bill. We are going to use this inverter on a wind turbine but first wanted to give it a thorough testing out to make sure it wasn't a lemon.

This wind turbine research is a cooperative effort between Berezin Technologies,LLC and Dr. Sanza Kazadi of the Jisan Research Institute ( www.jisan.org ). This is a simple, rugged drag based design modeled after a anemometer. The axle is using a patented technology developed by Dr. Kazadi ( www.google.com ). PWM Axial Flux generator is being developed now and product will be available for sale in July 2010.
