New Solar Cell Converts Heat to Light to Break Energy Production Barrier
Energy May 26, 2016TREVOR ENGLISH Trevor English


MIT has been working to make solar power more efficient and sustainable for some time now, in fact, not too long ago a research team developed a method of stacking solar cells that would almost double their capture efficiency. Now, a team of engineers at MIT have overcome the limit that was thought to forever define how much energy you could capture from the Sun, the Shockley-Queisser Limit. This Limit essentially states that there is a cap on the amount of power that can be collected by a solar cell due to the wide range of light frequencies, which is around 32 percent, according to Gizmodo. The new solar cells were designed to convert the excess heat energy from the sun into light energy that can be reabsorbed by the solar cell. Ultimately this increases the efficiency of the cells far fast the 32 percent limit, and it could change the green energy industry.

How To Calculate or Estimate Long-span Aluminium Roofing Sheets.

Image
Aluminium roofing sheets, they come in rolls of average of 600mm to 1300mm depends on the manufacture and specifications. As stated in previous articles, the aluminium sheets comes in rolls at the factory just like toilet rolls but with different widths and thickness based on specifications. Calculating the roof required could be done by calculating the surface area in square meters of the area covered by the aluminium and for some companies it could be calculated in meter lengths ,knowing the width which is 600mm above as constant. For a simple gable roof as shown in pic 1 with length of 25.2m. First you must know the height of roof from the section. For this sample we are taken the eight to be 3meters (10 feet)to know the length of leaf “x” or “y” Remember the pythagoras theorem x2=32 +6.12 x=6.8m Hence the area of roof is (6.8 i.e x)+6.8 i.e y) multiply by length 25.2m=342.72m2 If the width of the roof comes in 600mm or 0.6m, the length of the roof

Post Tension Slab – Advantages and Disadvantages of Post Tension Slab

Image
Post Tension Slab Although concrete is a strong material for construction, it is not resistant to breakdown especially where longer concrete slabs are required like in a bridge or a length of a beam. For this, the concrete slab is tensioned with a process called pre-stressing and the slab of concrete which comes out after this process is known as post tension slab. This slab is much stronger as well as more durable than the normal concrete slabs. In today’s world, where the modern engineering is finding new ways to build longer, more efficient and stronger structures, post tension slab becomes one of their chief requirements. There are many advantages and disadvantages of post tensioned slabs which we will discuss in this post. Advantages of Post Tension Slab Post tension slabs are advantageous in many ways. Some of the major benefits of post tension slabs are as follows. 1. Reduced cost: Post tension slabs are excellent ways to construct stronger structures at an affordable

How to install POP (plaster of paris) ceilling

Image
Plaster of Paris is regarded as any type of plaster containing calcined gypsum (calcium sulfate dihydrate), sand and water. When these ingredients are combined, they result in the formation of a tough, dry product; however, plaster of Paris can be sanded to achieve a variety of looks. By following some basic guidelines, you can use plaster of Paris to mend cracks, fix dents,for ceiling, in walls and even to create artworks. However in this case our focus is on ceiling. POP popularly called plaster of Paris is used for a lot of purposes because it can easily be formed to any shape and it hardens quickly and is easy to operate. To do a pop ceiling in your home, getting it done is in two ways, you can buy the materials yourself which include pop cement , yarn(sponge-like material) etc then pay the installer based on per square meter of area of coverage, or you can give it out totally as a contract. But these are the basic steps in getting pop ceiling cast-on-site done. Get cemen
