to save energy (Connected to a car) (Daryl)

Now time for the research dump written by Daryl.

- Solar energy

Solar energy is a renewable source energy meaning it would be extremely useful but not efficient as it is obtained as an energy from the sun's rays. The many different ways of using solar energy has widely increased.

Types of ways

- Electrical Generation

Description : Sunlight can be converted into electricity using photovoltaics (PV), concentrating solar power (CSP), and various experimental technologies. PV has mainly been used to power small and medium-sized applications, from the calculator powered by a single solar cell to off-grid homes powered by a photovoltaic array.

- Photovoltaics

Description : A solar cell, or photovoltaic cell (PV), is a device that converts light into direct current using the photoelectric effect. The first solar cell was constructed by Charles Fritts in the 1880s. Although the prototype selenium cells converted less than 1% of incident light into electricity, both Ernst Werner von Siemens and James Clerk Maxwell recognized the importance of this discovery.

- Concentrating Solar Power

Description : Concentrated sunlight has been used to perform useful tasks since the time of ancient China. A legend claims that Archimedes used polished shields to concentrate sunlight on the invading Roman fleet and repel them from Syracuse. Auguste Mouchout used a parabolic trough to produce steam for the first solar steam engine in 1866, and subsequent developments led to the use of concentrating solar-powered devices for irrigation, refrigeration and locomotion.

Concentrating Solar Power (CSP) systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. The concentrated light is then used as a heat source for a conventional power plant. A wide range of concentrating technologies exists; the most developed are the solar trough, parabolic dish and solar power tower. These methods vary in the way they track the Sun and focus light. In all these systems a working fluid is heated by the concentrated sunlight, and is then used for power generation or energy storage.

Basically solar powered vehicles are very limited due to need of having enough solar power produced by the sun so that the car has sufficient energy to run.

Information Adapted from http://en.wikipedia.org/wiki/Solar_vehicle :

Solar cars combine technology typically used in the aerospace, bicycle, alternative energy and automotive industries. The design of a solar vehicle is severely limited by the energy input into the car (batteries and power from the sun). Virtually all solar cars ever built have been for the purpose of solar car races (with notable exceptions).
Like many race cars, the driver's cockpit usually only contains room for one person, although a few cars do contain room for a second passenger. They contain some of the features available to drivers of traditional vehicles such as brakes, accelerator, turn signals, rear view mirrors (or camera), ventilation, and sometimes cruise control. A radio for communication with their support crews is almost always included.
Solar cars are often fitted with gauges as seen in conventional cars. Aside from keeping the car on the road, the driver's main priority is to keep an eye on these gauges to spot possible problems. Cars without gauges available for the driver will almost always feature wireless telemetry. Wireless telemetry allows the driver's team to monitor the car's energy consumption, solar energy capture and other parameters and free the driver to concentrate on just driving.

---------------

As you can see solar energy does saves up a whole lot of energy but is very limited. The power generated by the sun is by far one of the most useful source to us. However limited the usage of the car, if these solar powered converters usually know as solar panels could be placed on small materials like solar powered portable mini fans, it would be of great use.\\

Although solar power may seem to have its up and downside, there is another positive side to it. Since solar energy is able to be reused the next day, it could be named as an unlimited source, therefore Solar power energy is very extremely useful and is our main source for making this project work out.
