Hi Readers, do you know what Mr.Newton wrote about in his first published scientific paper? Let’s discover his big idea back to February 19, 1671.

The content of his first paper started with: A letter of Mr.Issac Newton, Mathematics Professor in the University of Cambridge; containing his New Theory about Light and Colors: Where Light is declared to be not Similar or Homogeneal, but consisting of difform rays, some of which are more refrangible than others: And Colors are affirmed to be not qualifications of Light, derived from Refractions of natural Bodies, (as ’tis generally believed;) but Original and Connate Properties, which in divers rays are divers: Where several Observations and Experiments are alledged to prove the said Theory.

This paper was proudly published by The Royal Society – world’s oldest scientific publisher. The good news is, The Royal Society has its world-famous historical journal archive – which includes the first ever peer-reviewed scientific journal – has been made permanently free to access online. Treasures in the archive include Isaac Newton’s first published scientific paper, geological work by a young Charles Darwin, and Benjamin Franklin’s celebrated account of his electrical kite experiment.  And nestling amongst these illustrious papers, readers willing to delve a little deeper into the archive may find some undiscovered gems from the dawn of the scientific revolution – including accounts of monstrous calves, grisly tales of students being struck by lightning, and early experiments on to how to cool drinks “without the Help of Snow, Ice, Haile, Wind or Niter, and That at Any Time of the Year.”

Being located in the equatorial zone, hot humid tropical region is commonly recognised as a promising site to adopt solar power systems. It has ample solar radiation with average daily irradiance of exceeding 5 kWh/m2. The sunshine duration could over 4 hours easily. Despite of these encouraging figures, the sky ineluctably facing cloudy skies and rainfall that might potentially challenge the performance of any solar powered technologies. Thus, the effects of this phenomenon should be accounted in the system design to promote the solar application in this zone.

Renewable Energy Solar Power

Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, windmills for mechanical power, wind pumps for water pumping or drainage, or sails to propel ships.
Large wind farms consist of hundreds of individual wind turbines which are connected to the electric power transmission network. Offshore wind farms can harness more frequent and powerful winds than are available to land-based installations and have less visual impact on the landscape but construction costs are considerably higher. Furthermore, offshore poses problems when considering accessibility for maintenance issues. Small onshore wind facilities are used to provide electricity to isolated locations and utility companies increasingly buy surplus electricity produced by small domestic wind turbines.

Wind power, as an alternative to fossil fuels, is plentiful, renewable, widely distributed, clean, produces no greenhouse gas emissions during operation and uses little land. The effects on the environment are generally less problematic than those from other power sources. As of 2011, Denmark is generating more than a quarter of its electricity from wind and 83 countries around the world are using wind power on a commercial basis. In 2010 wind energy production was over 2.5% of total worldwide electricity usage, and growing rapidly at more than 25% per annum. The monetary cost per unit of energy produced is similar to the cost for new coal and natural gas installations.

Wind power is very consistent from year to year but has significant variation over shorter time scales. The intermittency of wind seldom creates problems when used to supply up to 20% of total electricity demand,  but as the proportion increases, a need to upgrade the grid, and a lowered ability to supplant conventional production can occur. Power management techniques such as having excess capacity storage, geographically distributed turbines, dispatchable backing sources, storage such as pumped-storage hydroelectricity, exporting and importing power to neighboring areas or reducing demand when wind production is low, can greatly mitigate these problems. In addition, weather forecasting permits the electricity network to be readied for the predictable variations in production that occur.
