Comments Off on How to make a solar powered toy car

Ramchander Koushik.R: This article will teach you how to build your own solar-powered toy car. Knowing how to do this will not only benefit children, but also adults. When people are taught to use solar energy, they will become more aware of the fact that using natural sources is always better than thinking of sources that are fast depleting. Solar energy is available in abundance in all parts of the world. Children need to realize that electrical energy might not last really long. Drilling this thought into their minds at a really young age will augur well for the generations to come. Moderate level car Using the steps mentioned below, anybody will be able to build a solar-powered toy car. This is a moderate level version. Even if someone has to take this as a science project, they are free to do so. It will be an informative project and real fun too. Time required Once you have all the items required to make a solar-powered car ready by your side, it is just a matter of assembling them and putting the pieces together. Depending on your creativity and level of interest, it might take just about half-hour to a maximum of two hours to get your car completely ready. Resources required Most of the items required can be picked up easily from stores which sell radio control equipment. A wooden panel is the first item that you require. A 2*2 panel should suffice. Next, pick up DC motors that have rubber wheels. You require two such motors. Ideally, these have to be 1 to 3 V and about 145mA – 150 mA. 2 numbers solar panels (3 volts each) with all required wires two sided tape electrical tape rubber wheeling Estimated cost 1. Solar panels – $10 per panel 2. Wooden panels – $10 per panel All other items which you will need during the process would not cost you much. Detailed procedure to make the car 1. Now, we will shift our focus to understanding how to make your solar-powered car. Place the DC motors facing each other on the wooden panel. Once this is completed, fix the wheels to the wooden board. 2. The wires of the motor and the solar panel need to be connected with one another. Care should be taken to ensure that the positive gets connected only to the positive not to negative. If by mistake you connect the negative and positive, the circuit will not work. 3. Using the sticky tape, attach the panels to the wooden board. 4. Put the wheels to the front portion of the wooden panel to ensure that your car is balanced. 5. You have now completed the assembly. Leave your car in the Sun so that it gets charged through solar power. FAQs related to solar-powered cars 1. What other materials can one use other than wood? Ans. You might think of using a plastic bottle in place of wood. If you are creative enough, you can use even empty milk cans, CD cases and mobile phone panels as the body of your solar-powered car. 2. Where can I buy all the items required to make my solar-powered toy car? Ans. Most of the items which are required for making a solar-powered toy car can be purchased from stores which sell radio control equipments. Alternatively, you may also place orders for these components with online sellers. E Bay, Amazon, etc. are lots of sellers of these items which are available on online stores. Quick tips Rather than buying solar panels think of some DIY kits which are available in the market place and create your own panels. These are extremely cheap and would last longer than you ever anticipated. Things to watch out for There are not any dangers associated with solar-powered toy cars as such will stop, however, make sure that your kids are playing in an open ground and not in the terrace. There is always a risk of tripping and falling from the terrace, in case they are careless. Now that you have learned the procedure, it is now time to build your own solar-powered toy car. Initially, you might find it a bit difficult. As is the case with most other things, with practice, you will be able to become an expert in building your own solar-powered toy car and it will also give you feeling of joy and happiness. People wishing to exhibit this in their school science projects will definitely receive lots of appreciation from all people.

Future Perfect : Fusion power as a safe alternative to fission power

Comments Off on Future Perfect : Fusion power as a safe alternative to fission power

Divyam Singh: Fusion power as a safe alternative to fission power Fusion power as a safe alternative to With various countries undergoing liberalization for faster economic development, the energy needs of the world are growing at a very fast pace. The availability of fossil fuels is only for a limited time period and their effects are also very devastating for the global environment. As increased carbon levels in atmosphere have been found to damage economic systems throughout the world, the nuclear power is emerging as a more useful and easily explorable option for fulfilling the energy needs without causing any environmental damage. The common man in general has not been able to trust nuclear power and the word ‘nuclear’ still instills fear in many people. There are various dangers which people associate with the world nuclear. These includes the link between nuclear power and nuclear weapon, the nuclear disasters of Russia and Japan and the likely occurrence of such events in the future which can have catastrophic effects for mankind etc. The fast depleting energy sources have led the scientists to explore the area of nuclear energy and power in a much deeper way and such measures are being devised so that the nuclear power generation can be done in such a way so that there is no risk involved. One answer to the complexities mentioned above is thorium. thorium is a silvery metal which is present in the earth’s crust in abundance, is clean and is able to produce more energy when compared to uranium. As of now many countries are taking part in the fusion research with the EU, USA, Russia and Japan lading the way. Other countries contributing to a certain extent are China, Canada, Brazil, and Korea. In earlier days, both USA and USSR linked the fusion technology to their atomic weapons development programs. The fusion technology was classified till the year 1958’s Atoms for Peace Conference in Geneva happened. Thereafter, a breakthrough at the Soviet Tokamak made the fusion research as the most sought after ‘big science’ in the 1970’s. International cooperation for developing fusion energies ensures that cost and complexity of the devices which are involved in developing fusion energy no longer remain a setback and issue and the process is not hindered by economic shortfalls. Evolving trends In the last fifty areas, enormous progress has been made towards achieving scientific and technological progress in the field of fusion. The industrial scales containing fusion devices where plasma are manipulated at hundreds of millions of degrees are used by the scientists. JET or the Joint European Taurus-the central research facility of the European fusion program is also called as the JET. it is located at Culham, Great Britain. It is the most eminent fusion facility in the world and is the focus of significant fusion research funding. The state-of-art facility has enabled Europe to make great strides in the area of fusion research. Around twenty individual EU member states run a number of specialized smaller devices. The operation of JET started in the year 1983 after the facility was approved in1974. It met all its operational goals in the year 1990. After it, new scientific program were started and JET now also serves as a research facility and hosts a great number of operational researches. JET has been able to produce significant fusion power in the deuterium and the tritium plasma with numbers going up-to 16 MW in the short pulses which are characteristic of the current and existing experimental devices. The ‘beak even’ condition where the output power of the fusion process equals the external power which is inputted has been successfully achieved by the JET. The jet has also demonstrated clearly that the fusion devices can be operated in a very safe manner by using the tritium fuel. By using the remote handling techniques the radioactive structures can be easily maintained and also modified in the JET. The Eco Homes- the eco-homes use the cylindrical solar panels for generating more power. The eco house, which is 800 square foot in size uses the solyndra cylindrical photo-voltaic which by their unique shape capture more amount of sunlight when compared to traditional solar panels. The system is also termed as the green roof integrated photo-voltaic or the GRIP V. Here the green roof located beneath the panels help in creating greater efficiency for powering the solar house. The green roof underneath ensures that the reflectivity is minimized and the greenery regulates the temperature of the solar panels which are located above the house. The house is expected to produce zero emission. The house has been built using sustainable materials. The wood sided flooring is obtained form an old Pennsylvania barn and the house also has an indoor garden which contains herbs and other plants. MIT’s Alcator C Mod Reactor- MIT’s Alcator C Mod Reactor is the tokamak type fusion reactor which is university based. The new process of fusion burn has been revealed after 30 years of experiments which have been done at this reactor. The basic operational problems of the fusion reactors can be solved by this reactor. As per MIT news,self heating sustains the power and fusion reactions in this reactor and no outside heat supply is needed. The Concept- When the nuclear processes generate power the power is termed as nuclear power. A fusion reaction is said to occur when two light atomic nuclei bind or fuse together to form a more heavier nucleus. While binding, a large amount of energy is released which arises form the binding energy that occurs due to strong nuclear force that is manifested as an increase in the reactant’s temperature. The fusion power forms the primary research area in plasma physics. The Advantages- the reaction of the nuclei of tritium and deuterium produces fusion power. The availability of these hydrogen isotopes is in in-exhaustive proportions. The fusion reaction gives helium as its byproduct which is not harmful to the environment. Moreover the fusion reaction does not gives any harmful waste as is the case with fission reaction. Thus, the energy obtained from nuclear fusion reaction can be the answer to global warming, nuclear waste and the impending energy crisis. The impact- the fusion power and energy can be seen as the future in-exhuastible source of energy for the whole world. Many researches are currently going on in the area as there are extreme scientific and engineering challenges in this fled of energy production. Different countries are contributing their scientific expertise and research acumen and working towards the attainment of fusion energy by their combined efforts. This is in sharp contrast to the initial days of exploration of fusion energy when countries like USA and USSR kept the fusion energy exploration processes secret.
