Google is always known for it’s quality service and superb software. Here, we are giving you an example of the work by our expert Shashi Prakash Agarwal on Google Sketchup. He has created a dream home in Google Sketchup and further enhanced it with optical fiber and hybrid lighting system solutions.
A must watch for everyone. It’s high time to conserve the environment and energy. Energy can neither be created not destroyed but can be wasted easily. To stop this wastage, it is always our objective at techite.com to promote such creations which make people aware about eco-friendly ideas or alternatives to the normal conventional sources of energy.
An independent solar /battery power system is called a stand-alone solar electric energy system. It uses a large solar panel, a large capacity lead acid or nickel based battery, a power inverter to convert the low-voltage DC into utility AC, and a sophisticated charging circuit. Such a system is best suited to environments here there is sunshine a high percentage of the time.
Solar cells, either alone or supplemented with rechargeable batteries, can be incorporated into an interactive solar electric energy system. This requires a special arrangement with the electric utility company. When the solar power can’t provide for the needs of the household or business all by itself, the utility program can take up the slack. Conversely, when the solar power system supplies more than enough energy for the needs of the home, the utility company can buy the excess OR store it in batteries.
Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.
An optical fiber is a thin, flexible, transparent fiber that acts as a waveguide, or “light pipe”, to transmit light between the two ends of the fiber. The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune to electromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers.
Lighting costs money—more than most people realize. The costs are not just simply the prices of fixtures, replacement lighting elements, and the electricity to operate them. We must also pay the price for artificial lighting’s inefficiency—namely, its production of heat. About 10% of our cooling and ventilation costs result from clearing away the heat generated from lighting. As the use of artificial illumination has grown more extensive and necessary, numerous efforts have been made to reduce cost, increase efficiency, and improve quality. Significant improvements that have resulted over the years include extensive use of fluorescent fixtures; halogen, sodium, and mercury vapor elements; and automatic turn-on and turn-off systems. Compared with standard incandescent bulbs, these improvements have been major; nevertheless, the world’s light bill will continue to rise considering that the amount of office floor space is expected to double worldwide by 2020.
Hybrid lighting is a combination of natural and artificial illumination to be used indoors for all lighting needs. Ideally, hybrid lighting is effectively indistinguishable from standard artificial lighting except in quality and cost, where it will likely be an improvement. Hybrid light fixtures will allow use of all available natural light and supplement it with the amount of artificial light required to bring the total level of illumination to the rated value. As shown in the graph below, the level of natural light available is quite high during working hours in most places on most days. For many hours during a typical work week, essentially all illumination could be provided by natural light. In fact, fully hybridized lighting in industrial and commercial working environments could cut artificial light requirements in half. By combining natural light and improved artificial sources available today—centralized, high-efficiency light sources—energy costs for lighting could be reduced by one-third.
The Need for Hybrid Lighting
Considering the light bill for the industrialized world today, there is a financial incentive to use higher-efficiency lighting. The real problem boils down to two factors: cost and degree of user friendliness. If you entered a hardware store tomorrow and heard that new, twice-as-efficient lighting fixtures were available free of charge with free installation, you would probably ask for them. If, at the other extreme, you were told that the price of the fixture and its installation would be prohibitively high, you would not be interested in them. The goal of hybrid lighting development is to find the practical middle ground: costs that are manageable and future savings that are significant.
Lighting costs are an issue because they include not only fixture prices but also installation, retrofitting, and maintenance. When new construction is planned, modern lighting costs that are higher than those for standard, low-efficiency lighting can be justified (unless they are exceptionally high), because of long-term efficiency. For retrofitting, the same argument holds, again, as long as the cost is not extraordinary. For maintenance it is important that hybrid systems cost little if any more than today’s standard systems. Long-term efficiency improvements can pay for only so much. Despite the massive benefit to the whole society that accrues when large amounts of electric power are saved, individual investors will not cooperate unless their individual “bottom line” is in the black.
This system can decrease electricity cost and wastage of electricity due to usage of artificial lights.
