Road Energy Utilization

Introduction:

 

In this project we will utilize rood energy. We will generate electricity from the vehicle moving on the road. There are two ideas to make this project. One is with weight factors and other is with rotational energy. In first method when heavy vehicle will move on road then it will pass from speed breaker. Speed braker will be connected with spring. Which will help to move gear assembly. Gear assembly will move the shaft  of alternator. And  alternator will give electric output. That electricity will be stored by us in invertors to utilize later for commercial purpose. And another method is  to us tyres on road. Which are connected with shaft & will help to move shaft of alternator. In this way we can generate electricity

 

 

What is dynamo

 

 

Objective- Rotational Energy Saving

Introduction about project- In this project we will utilize the rotational energy. We know that  traffic is increasing CONTINOUSLY these days. Thatís why there  is lots of energy wastage without usage. We can utilize these energy .

We use rotational energy - friction energy of vehicles  to generate electricity. Electricity we know the value of it .  No need to explain its uses. So we are saving energy for street lights.

When vehicles will pass from road then energy will be changed in to electric energy using dynamo.  Converted electric energy can be stored in Battery. But we are not using battery because we know that when we will store energy in battery then it can not show in project that we are generating

Most of us are aware these days that the world-wide demand for electricity is actually growing much faster than the population, and that the cost of building new electric power plants and fueling them has become staggering. We have also heard that power shortages and 'brown-outs' are becoming much more common. What many might not realize, however, is that the world's pressing need for fresh water may well become the most critical resource issue of the early 21st century.
 
    In 1997, a United Nations freshwater resources assessment found that at least half a billion people then lived in countries with conditions of moderate to high "water stress". This figure is expected to rise to 3 billion by 2025, by which time the industrial use of water is expected to double. This sad situation is potentially desperate for developing countries with high water stress and low per-capita income. At the present time, nearly a billion people do not have access to clean drinking water. Countries in the more arid regions of the globe are especially vulnerable: in
Israel, for example, the annual fresh water deficit exceeds 50 billion gallons, about 10% of their total yearly demand.
 
   Even in the United States, shortage of water is an issue of major concern in large metropolitan areas from Los Angeles to Tampa. Much of California will be chronically short of water by 2010; the big cities of the Southwest could run out of water in 10 to 20 years; and Florida's reservoirs are nearing depletion levels while its water table is increasingly briny from seawater infiltration. Even cities in the Great Lakes region, which encompasses one-fifth of the world's surface fresh water, may very well face serious water shortages within 20 years
 
   The World Resources Institute in Washington, DC recently reported that even with the implementation of stringent measures to control the global growth of demand and require that fresh water be used more efficiently, most particularly in the irrigation of farmland, new sources of supply will inevitably be needed. Historically, the desalinization of seawater has always been viewed as much too expensive to represent a reasonable solution to our water shortages. But with the advent of the StarDrive Electronic Dynamo developed by Archer Enterprises, this may no longer necessarily be true.

On an iron ring twelve equal windings are winded in five layers of a 3-tenth wire and they can be connected between them in three different manners, by two interruption hooks and four plugs fixed on the basis.
  According to the directions attached to the apparatus in the first connection (single-phase), the twelve windings are in series and the current is taken on two diametrically opposed points.
  In the second connection (two-phase), the twelve windings form four sections of three series elements; then the four sections are connected in series: the first with the third and the second with the fourth. In this way we obtain two couples of free ends that will give us the two-phase system.
  In the third connection, the twelve windings are still connected in series, and the current is taken from three points at 120 degrees one from the other (three-phase system with a delta-connection).
  The ring is fixed vertically on a brass basis that supports also the inductor system formed by an electromagnet turning in the plane of the ring and stimulated with a battery of accumulators (8 V) or by a direct current with a maximum intensity of 5 A.
  A heavy flywheel helps to make the electromagnet rotation regular. The connection is all-visible and the ends of the twelve sections are fixed to metallic gaskets, joined between them with mobile bridges, so that we can make different combinations from the one indicated above.

Electricity generation is the first process in the delivery of electricity to consumers. The other processes are electric power transmission and electricity distribution which are normally carried out by the electrical power industry.

Rain Water Harvesting

Rainwater harvesting is the collection and storage of rain from roofs or from a surface catchment for future use. The water is generally stored in rainwater tanks or directed into mechanisms which recharge groundwater. This is appropriate in many parts of the world, such as western Britain, China, Brazil, Thailand, Sri Lanka, Germany, Australia and India, where there is enough rain for collection and conventional water resources either do not exist or are at risk of being over-used to supply a large population. Rainwater harvesting can provide lifeline water for human consumption, reduce water bills and the need to build reservoirs which may require the use of valuable land.

Traditionally, rainwater harvesting has been practised in arid and semi-arid areas, and has provided drinking water, domestic water, water for livestock, water for small irrigation and a way to replenish ground water levels. This method may have been used extensively by the Indus Valley Civilization.

Currently in China and Brazil, rooftop rainwater harvesting is being practised for use for all the above purposes. Gansu province in China and semi-arid north east Brazil have the largest rooftop rainwater harvesting projects ongoing.

Rainwater harvesting in urban areas can have manifold reasons. To provide supplemental water for the city's requirement, to increase soil moisture levels for urban greenery, to increase the ground water table through artificial recharge, to mitigate urban flooding and to improve the quality of groundwater are some of the reasons why rainwater harvesting can be adopted in cities. In urban areas of the developed world, at a household level, harvested rainwater can be used for flushing toilets and washing laundry. Indeed in hard water areas it is superior to mains water for this. It can also be used for showering or bathing. It may require treatment prior to use for drinking.

Two residences in the city of Toronto, Canada, use treated harvested rainwater for drinking water, and reuse water (i.e. treated wastewater) for all other household water applications including toilet flushing, bathing, showers, laundry, and garden irrigation (Toronto Healthy House).

In New Zealand, many houses away from the larger towns and cities routinely rely on rainwater collected from roofs as the only source of water for all household activities. This is almost inevitably the case for many holiday homes.

Rain water harvesting is one of the best way to utilize our natural sources. We know as population increases continuously,it decreases our water sources.
