Blinds are used in many applications, but most of them are just to cover the sun or to protect privacy. The Eco Leaf shutters, designed by designers L im Wan Xuan and Tang Xueling Jane, are distinguished from traditional shutters. The solar cells used in the fabrics not only function as traditional shutters but also absorb sunlight and convert them into electricity. Charging during the day can also block the sunlight, and at night, the small leaves on the curtains will glow, giving the room a warm illumination. A small monitor above can also show the temperature of the room. At the same time this Eco Leaf was nominated for the 2011 Liteon Grand Prix.
what makes most electric power tools "different" from one another depends on how the physical energy is used, or its application. The process of making physical energy with electrical energy is very similar and where most performance issues occur. for most power tools, and happens to be where most maintenance is required
Although there is a lot more to be said about how electric motors work, no one has to be an electrical engineer to understand a motor's basic parts. And understanding what goes on inside of a power tool makes diagnosing problems easier.
If the problem can be pinned down early, then the tool is just a part and a quick repair away from being almost like new again. Even some of the repairs and maintenance required for electric power tools are fast and easy to do.
