Solar Window Solar windows are windows that function as solar panels to harvest the sun’s energy and convert it to electricity. Building owners can purchase solar windows to replace existing windows or buy solar film to retrofit existing windows. In the past, materials scientists have embedded light-absorbing films in window glass. But such solar windows tend to have a reddish or brown tint that architects find unappealing. The new solar window technologies, however, absorb almost exclusively invisible ultraviolet (UV) or infrared light. That leaves the glass clear while blocking the UV and infrared radiation that normally leak through it, sometimes delivering unwanted heat. On a skyscraper, where rooftop solar panels can only provide a fraction of the massive amount of energy that big buildings use, the new windows could power a much larger chunk of an electric bill. Rooftop space available for conventional PV is so limited it is difficult to generate meaningful ene

Solar Powered Tent for Campers:   Recreational camp­ing is all about communing with nature and spending time with your family outdoors be it in the park, at the beach or in the woods. To differentiate from regular life that make it count: Cooking over a fire instead of over a gas stove, sleeping under the stars instead of under a solid roof, carrying water on your back instead of turning on a faucet If you love outdoors and enjoy camping, you’ll agree that the tent is a very important equipment. It provides us shelter and most importantly, it gives power supply in your camping. Solar power is a common alternative energy source these days, and it's not just giant solar panels on buildings anymore. The U.S. military is developing flexible solar-panel fabric that can be used for tents and uniforms. And on the civilian front, you can use small, portable solar panels to power devices like cell phones, MP3 players and digital cameras -- and for indoor tent lighting, it turns out. Ther

In cities, usually we will be little worried about drying clothes in our balcony. During winter and rainy, we try a lot to dry our clothes, turning them, changing to sunlight, fading out colour, if receives too much sunlight. Here we got a hanger rack that can be automatically rotated by solar power generation. Compared with traditional hangers, this hanger can greatly reduce the drying time of the clothing. It will sterilize the whole surface, eliminate bacteria, protect family health. An Innovation different way from traditional clothes drying method. It is a hanger rack that can be automatically rotated by solar power generation. Compared with traditional hangers, this hanger can greatly reduce the drying time of the clothing. It will sterilize the whole surface, eliminate bacteria, protect family health.   The hanger rack can rotate 360 ° to sunlight the laundry in all directions. Derived by rigorous calculation, It can reach 6 rotations per minute moderate rotation speed. Th
