Ship in Santo Domingo Harbor, Dominican Republic

I saw this ship docked in the harbor at Santo Domingo, Dominican Republic in February 2008. I used my new Kodak Z812IS camera with built in panoramic stitching to take this shot. Well the shot was way too large to display on the internet, so I used a free tool from the clever Brits at for displaying panoramic photos on websites after first downsizing the number of pixels in the image. The final product is a flash object which can be embedded in any web page or blog. Let me know what you think.

Dominican Republic

Just returned from the Dominican Republic. We stayed in Santo Domingo for about a week and had a great time. We stayed with a relative who is working on the new subway project and got to see the country in a non-tourist fashion. I will post a movie shortly on some of our DR experiences.

I looked for wind turbines when I was there but found none. A pilot project was abandoned, purportedly due to "lack of wind". The wind was blowing 10-20 knots north of Santo Domingo most of the time I was there so I want to go back to the DR with some VAWTS and see if they are viable.

VAWT video

Here is a video demonstration of our sub-$100 VAWT.

If you want to make one yourself, here is an instructional video (about 8 minutes long).

Here is a video of it running in some gusty winds.

Wind Power, CNC, and More

Welcome to my blog. Here I will keep you abreast of new developments at the Berezin house. Currently, we are developing an inexpensive "build it yourself" VAWT (vertical axis wind turbine). After checking locally for a wind turbine and finding entry level prices in the $3,000 to $5,000 range, I decided to build a plastic barrel VAWT. Last week we bought a CNC machine to fabricate parts for our VAWT. I will be publishing videos of our progress on these projects.
