Fiber Reinforced Polymer (FRP): A material to strengthen deteriorated and damaged constructions

The need for repair and strengthening of deteriorated, damaged and substandard civil infrastructure has become an important challenge confronting the repair and rehabilitation industries worldwide. Deterioration of structures begins shortly after completion of construction due to environmental influences and/or due to the structures’ routine use. Deficiency of structures may be the result of insufficient reinforcement, excessive deflections, poor concrete quality, reinforcement corrosion, or insufficient bearing capacity.

Now, Continuous development of Fiber Reinforced Polymer (FRP) materials in various form sand configurations offers an alternative design approach for the construction of new structures and rehabilitation of existing civil engineering infrastructure. Nevertheless, their applications to structures are still relatively few. FRPs offer designers an excellent combination of properties not available for other materials and present a potential solution to civil infrastructure's crisis. High strength-to-weight ratio, ease of installation and corrosion resistance characteristics make FRPs ideal for strengthening applications. Externally bonded FRP sheets and strips are currently the most commonly used techniques for strengthening bridges and concrete structures.

Windbelt: A new wind power device
Traditional micro wind power devices are plagued by various problems and he output of a classic micro–windmill is very low because there is less wind and more turbulence in a built-up environment — they hardly deliver enough energy to power a lightbulb. Because of the low yield, micro-wind turbines are also much more expensive for every delivered kilowatt-hour of electricity.

Young American inventor Shawn Fayne has designed a wind power device that does not have most of these disadvantages: the windbelt. It’s the first micro–wind machine that does not try to miniaturise the concept of a big turbine, but instead takes a completely different view; the machine does not include any mechanically moving parts, but makes use of vibration.
Small prototypes of the wind membrane (it cannot technically be called a windmill) have produced 40 milliwatts with a wind speed of 3 Beaufort. This makes the device 10 to 30 times as efficient as the best micro-wind turbines on the market today. That profit is made because with a traditional windmill lots of energy is lost by the friction of mechanically moving parts.

Floating windmills: Energy from the clouds
The most important disadvantage of wind power is that there is not always (enough) wind. Wind turbines only spin one tenth of the time at their maximum output, which makes wind not a very reliable energy source. At higher altitudes, wind conditions are much better. Floating windmills, which send the generated electricity to the earth by means of a cable, could harvest much more energy. Wind speed increases with altitude. Because wind power corresponds with the cube of wind speed, the amount of energy that can be harvested grows exponentially as one goes higher. Historical data from the Dutch weather institute shows that at a height of a thousand metres, wind power is on average 6 times stronger than at an altitude of 100 metres. At an elevation of 5,000 metres, there is 17 times more wind power. At a height of 10,000 metres 30 times more wind power can be gathered.

A common wind turbine stands at a maximum of 125 metres tall — twice as high as ten years ago. Nothing stops us from building even taller windmills, but floating wind turbines could provide a cheaper solution. The idea is all but new. At least 3 inventors have been testing the concept for some decennia, making models and building small prototypes.
