It so happens that we need uninterrupted power supply for some time and it is cut off! So what we do in that case? We simply wait, nothing more. But Rupert does not!
Rupert Sweet-Escott, has invented a wind turbine which you can easily mount on your roof top.
The conventional wind turbines you must know are quite bulky ones. The blades rotate around a horizontal axis with which is mounted on a very long pole. Actually there are not one, but many. Such places are called wind farms. There are special places for developing these farms. The primary requirement is wind, it should flow regularly at a required pace. Moreover, they make very loud noise. To solve these problems, Rupert accidently, thought about making something which can be fitted right on our roof tops.
He aimed at eliminating all these problems. He also wanted to make these devices reliable. Eventually, a design which he finally thought ‘suitable’ was a turbine rotating about a vertical axis. Taking into account, he settled with two sizes 60cm and 100cm. The design which he actually settled for resembles a cylinder. According to Rupert, the horizontal axis designs actually a very efficient, economical and reliable only for large wind farms. For small scale applications like this one however, the vertical axis is good. And more what, it does not even need much of a maintenance. The smaller one of the two comes for £750 while the larger one costs £1,865. Pretty costly though, but it is just a onetime investment. It will pay you rich dividends in terms of saving your electricity bills.
Now, how much does it make? On an average, it would provide with half of your domestic consumption. If you install a smaller one, it can produce power equivalent to 5Kw while the larger one is twice of that.
