Science Fair Projects Made Fun! -
Wednesday, May 22, 2013
Science is uneventful, lifeless, dull, and just plain boring! Unfortunately, this is a sentiment shared by thousands of students. Schools have taken what is actually a very FUN subject (yes, I said science is FUN) and turned it into a geekfest of boring technical textbooks, lame experiments, and stuffy professors with no personality.
When it's time for the local Science Fair, many students just don't show much interest or put forth their best effort. Part of the reason is the array of lifeless and lame science fair projects they're tasked to perform. If the projects aren't fun or interesting and there is already a pre-conceived notion of Science as being boring, how can anyone expect the students to really try? The answer can be found at a new website that is putting the fun back into Science! At the Science Fair Adventure (http://www.ScienceFairAdventure.com), you're going to find more than just science information and news. Covering categories that include Physics, Biochemistry, and even Computer Science, the Science Fair Adventure will become your definitive resource for Science Fair Projects'! Each science fair project features everything you need to conduct the experiment from beginning to end, including step-by-step project instructions. Best of all, each project is explained in detail to allow the science novice to fully explain the observation and results of the experiment. If you find a project you like, you can bookmark it, share it on social bookmarking websites (such as Technorati), rate it, or email it to a friend! The Science Fair Adventure is putting the fun BACK into science!

Wind turbines -
Wednesday, May 22, 2013
wind turbines' convert wind into kinetic energy to create electricity. The force of wind causes the large blades of the turbine to spin. As the blades turn the energy created is piped through a narrow shaft into a gearbox, which relays the energy to a generator. Wind turbines are typically configured in groupings, called wind farms, and are primarily found in farm areas with constantly high wind speeds to bring the best return on investment.
The investment in renewable energy sources is an important one. Having the right resources and qualified technicians who are trained in wind turbine maintenance' is essential to keeping the investments working. The focus needs to be placed on maximizing long-term productivity while maintaining environmental safety and adhering to the strictest code of ethics.

carbon fiber sheets -
Wednesday, May 22, 2013
Protech Composites manufactures carbon fiber sheets', panels and carbon fiber fabrics' used for Aviation, Marine and industrial applications.
So, what is carbon fiber? Carbon fiber is the super hero of the materials world – it’s one of the strongest and most lightweight materials available on the market today. Five times stronger than steel and one third its weight, carbon fiber composites are often used in aerospace and aviation, civil engineering, military, car racing and other competitive sports applications.
Carbon fiber starts as very, very thin strands of fiber that are finer than a human hair. These strands are twisted together like yarn (called a tow) and woven into carbon fiber fabric which typically comes in 3k, 6k and 12k weights. A 3k fabric has 3,000 strands of carbon in each tow while a heavier weight 6k fabric has 6,000 strands per tow.
Carbon fiber fabric comes in a variety of weaves that have different strength properties. Weave is critical for two reasons – appearance and functionality which also impacting strength. A unidirectional weave creates a carbon fiber sheet that’s very strong in the direction of the fibers, but weak in the opposite direction. Plain and twill weaves, on the other hand, have more uniform strength since they’re strongest at the points where the fibers cross in either direction. At Protech, we use a 6k 2x2 twill weave for our standard product line; we’ve chosen it for its all around strength and good looks. We also work with a variety of other fabrics for custom orders.
To make carbon fiber fabrics' (also known as a composite), carbon fiber fabric is saturated or infused with epoxy resins and heated at high temperatures. Shaped pieces are made by layering several pieces of fabric over a mold, saturating them with resin and heating it until the resin has infused through all layers.
