Whats The Best Snowmobile Helmet On The Market

In the early XX, electric cars were more common than internal combustion models for multiple benefits ranging from silent to the fact that work this type of vehicle does not produce noxious fumes of high character. it happened that this type of vehicle began to decline in sales, this is because electric cars have a limited scope. At the beginning of the century, this was not a problem because the only routes were suitable for driving in cities. However, after the First World War, nations began to build highways and roads linking their cities. Which hindered the work of the electric vehicle.

The discovery of abundant oil resources from its depreciation allowed, making gasoline more affordable again to society. But electric cars have not disappeared and the oil crisis back to get known in the automotive world of business, but were best known by the need for countries to adopt sustainable transport measures, to overcome the high environmental pollution affects the world. .

theory prototype electric car, is directed to solve the biggest problem of environmental pollution. You do not need a combustion engine to recharge the battery and internal combustion electric car. Since this electric car can self-generate their own electricity, exploiting the fact that the shape of turning a wheel on a car is similar to the constant rotation of a wind mill resulting in the production of clean electricity.

This car uses the same principle used in hydroelectric plants, which convert the speed and weight of the water into electricity. These examples show that it is possible to convert the displacement speed and weight of a car into electrical energy.

Operation

The electric car is battery operated previously recharged by an external source (such as the outlet), which sends the electricity that the engine needs to drive the car. The car's acceleration will make by spinning the wheel generators, they produce electricity, which is stored in the battery, which in turn sent back to the engine that moves the car.

Unlike the electric car internal combustion car is a type of machine that obtains mechanical energy directly from chemical energy produced by burning fuel in a combustion chamber, the main part of a motor.

Among the many advantages of an electric car a combustion front is the first that does not pollute the environment further. Resulting in a healthy alternative to global warming. Second is the economic manufacture. A burning car has about 7000 different pieces. 40% of business from automakers aftermarket parts and repairs that are virtually electric vehicles. This electric car obviously requires no combustion engine, gearbox, crown, etc cardan. If they are essential in a combustion engine car. This means that will reduce costs of production or manufacture. Resulting in price accessible to all audiences. To this we must add a minimum maintenance and economical as it does not need fuel, the savings grows much more and for the owner, but above all the environment. Costs

The constant hikes in fuel prices has made us see ourselves in the need to find a solution to the large investment we make to our daily mobilization.

On 19 August this year, arrived in Chile-called first 100% electric car, a small Indian-made motor model, called REVA. Having a vehicle be charged by simply plugging and not contaminate the dream of many, but what the numbers back him?

This car measures 1.5 meters high, 1.3 wide and 2.6 long. It was designed for congested city streets, has a top speed of 80 km / h, accelerating from 0 to 40 km / h in about 8 seconds. To charge your battery at 100% must be connected for 8 hours at 220 volts, which allows 80 km of autonomy.

REVA

The connection to the power supply costs about $ 130 per hour. That is, a little over $ 1,000 to go 80 kilometers. Not bad, considering spend a conventional car in the same mileage, about $ 2,400 pesos.

Another advantage is the environmental impact it produces. It is true that a zero-emission car helps the environment. However, little use if its use does not become massive, which is the REVA very unlikely, due to its high cost. And in a country like Chile, where the electrical system is not based on so-called "clean energy", each charge of EVAR to the grid, means that "the other side of the plug" is a plant, coal or diesel polluting. The use and promotion of electric cars in our country must be necessarily accompanied by the use of clean and renewable energy.

The Chinese market presents us with another alternative, the "C-ro", belonging to the US-1 brand in China. This model requires 8 to 10 hours of charging, the difference is that spending is $ 700, which allow us to drive 130 kilometers, reducing the cost by 80%. Reaches a maximum speed of 60 km / hr and its selling price is 4 million plus VAT.

By way of comparison, the performance of a combustion engine vehicle is below 40%. So in 10 liters of gasoline launched 6 liters in the form of gases, heat, noise, vibration, waste, etc. More than 400 million tons of carbon dioxide is sent into the atmosphere each year by vehicles worldwide. Oil consumption in the world representing more than 87% of global warming. 90% is generated by cars, ie over 78% of global warming due to the use of oil in internal combustion vehicles. The world is made up about 160,000 cars. Circulating more than 3.000 million vehicles that emit greenhouse gases. In contrast, the level of pollution generated by electric cars is not even half of the pollution generated by burning vehicle internal, making it very favorable electric car use, both for the environment and for personal gain.

Although the benefits of electric cars are higher, as the environment and vehicle costs, compared to internal combustion car, its use has been massive and there are multiple reasons for this question, which mostly relate to the security gained from an electric vehicle and the convenience of capitalists to maintain high profits from sales of cars that use internal combustion of fossil fuels a more lacking in the world, increasing its price and and gains the automotive-related trade.

Studies show the great benefits that produce electric cars, both for ourselves and for the environment. But the question of the majority is, Why not in the market yet?

The main advantage is that electric cars are charged by electricity, but this brings condigo a small storage capacity of batteries in the car and long recharge time, which still causes pollution, since electricity is produced by burning oil and coal, bring essential spending by industry and government. For it is said that one of the many opportunities that this market still is in the amount of money needed Parea develop this unique way to recharge electric cars.

Another difficulty that prevents these electric cars were installed in the market is definitely where the difficulty of charging its batteries, should be designated places where you can charge the battery, bringing more spending for the government because it would only be an installation, distance but each would have to build a loading station for the car, plus the batteries must be renewed every 600 loads (two years approximately) at a cost of $ 700,000.

Another major difficulty is that the flammability of hydrogen, what batteries are constructed to operationalize the car, would be a great danger to everyone. A hydrogen leak could trigger an explosion highly potent. In several countries, these cars are unsafe because they were tested to qualify their safety, in one of these was a car collided 64km / h against a deformable barrier simulating the collision with another car. The result was disastrous because the car was totally destroyed and the driver dummy that had ended up torn between the metal of the vehicle. After this test electric cars are not easily implemented in different markets.

Finally, there is another reason that causes the electric cars are not sold to the masses. Currently

barrel of crude oil is around $ 130 (about 81,510 Chilean pesos) and about a liter of petrol costs 750 Chilean pesos, unlike the general use of electric vehicles equivalent to approximately 1000 pesos Chileans, for distances of up to 80 km with a speed of 80 km / h. Although the provision of internal combustion car is more immediate than the electric car, your costs are much lower, which could jeopardize the investment of hundreds of businessmen who prefer contained automotive electric vehicle sales (which generate less pollution and short term are more economically desirable) to increase profits.

We may add, finally, we believe that these obstacles can be overcome in a not too distant future. Technology advances and new ways to solve these problems soon arise. We'll see how in a few years the mass of electric cars will be real.

If you have enough money Would you invest today (with current technology) your money on a car like this?, explain why.

Consider the famous car REVA, who arrived in Chile with great fanfare, and emerges as the main tender to completely eliminate the pain caused by instability pocket of oil.

But we would buy a car like this? We face a difficult decision.

analyze benefits and detriments to buy a model like REVA to make a decision. So go with the concrete.

Based on those of the press [1] this car would cost about 6.7 million pesos. Quite high considering it is a small car in few seats inside. It is a city car designed for city use only, with a very limited range (about 80 miles on a charge of 8 hours) and a maximum speed of not more than 80 miles per hour. But instead, according to various sources, the first argument to buy electric cars is economic.

could say that the average Chilean spends about $ 80,000 monthly maintenance of your car, including spare parts, fuel and insurance. [2] With a car like REVA significantly reducing costs:

First, the maintenance costs are almost nil, and the engine does not require special maintenance. Also, the companies importing the parts are cheap, the car tends to fail a lot less than a conventional one and uses less brake and tire.

Second, expenditure on fuel is removed entirely, replacing it with a suitable yield of 80 miles for about $ 1300, which gives us, making a parallel with a conventional car, a consumption of about 47 kilometers per liter (considering the price of gasoline $ 750), an amazing value and unthinkable a few years ago.

loading facility also makes a car like this is convenient. It connects the car by any standard outlet, no adapters of any kind. To charge 100% of the batteries are required eight hours and for 80% capacity just two hours.

is the perfect car for novice drivers, since it has no gearbox. It also foresees that exemption from the registration certificate for 4 years for those who purchase this type of car.

Finally do not forget the environmental need. The existence a car with virtually no emissions in a world that needs it most every day is not a minor issue.

Given the speed with which the runs progress, we are sure that in some years there will be new technologies that go far beyond what we choose today, but immediate action is required. It's a hard desicion, I even risky, but investing in an electric car is very productive.

We decided. If we had the money now in our hands, we would buy an insurance.
