At last we have some good news to report! As I mentioned before, we have had delivery of the first 10 RidgeBlades. After a slight delay due to the heavy snow, we have now got the first two units installed, and we are very pleased with the results. As you can see, the finished unit looks very much like the artist's impression in the previous blog entry. As with any new product we have encountered a few small teething problems which are already fixed, and will be incorporated into future production versions of the RidgeBlade. Until you actually have a builder on a roof installing the things, all you have is theory, and the modifications are mostly to do with making the units easier to work with and install - I'm pleased to say the the actual operation of the units is exactly as we had expected. It's too soon for any output figures yet, but there's nothing to suggest that we are going to be disappointed. One thing that I can say is that the units operate almost silently - so that's another objective achieved. As ever, we seem to be progressing much more slowly than we would like, especially given the level of interest around the world, and it can sometimes be very frustrating, but I recently spoke to someone within a much larger wind turbine company, and they were amazed at how far we had come in so short a time, so I suppose that it is all a question of perspective. So our "to do" list is pretty clear: incorporate modifications into the design of the next production units, install the remaining 8 RidgeBlades, gather lots of data about real-world performance, and then see if anyone wants to buy one....
